digital batteries

1, the pricing of common sense

Here, we must first note that the load is an important step in the use of rechargeable batteries. Load appropriate and reasonable to extend the battery life is very good, while the random brutal life of the rechargeable Laptop battery will be greatly affected. On one side, said the current lithium batteries are based on the basic package of each product individually and not jointly, if different products to provide their own equipment for loading, and not common, when in service as long as you can use to follow their instructions. While it is the introduction of the battery refers mainly nickel-cadmium batteries and nickel-hydride batteries in metal.

The battery compartment on nickel and nickel hydride batteries, metal, there are two ways in which we are known as “fast charge” and “trickle charge”. Quick charge and trickle charge is the charge of an important concept, and only learned about the fast charge and trickle charge in order to properly grasp the load.

Firstly, the fast charge and trickle charge is a relative concept. Some people have asked, my charger with charge current of 200mA is not load quickly? The answer is not absolute, should have answered some batteries is fast charging, and some batteries, it is simply loaded slow. So how can we judge fast charge or slow charge it?

For example, a 5, Ni-MH power capacity IBM ThinkPad T41 battery of 1200 mAh, while the other section is 1600mAh. We have a battery capacity is called 1B, 1C see is a logical concept, the same 1C, are not equal.

During loading, the load current is less than 0.1C, we called the trickle charge. As its name implies, refers to the current very low. In general, the burden of maintaining the battery can be comprehensive without harming the battery, but the trickle charge to use the time spent far too long, so rarely used alone, but rather, and other pricing methods used in combination.

0.1C, 0.2C charge current between the two, we called the trickle charge. Load current is greater than 0.2C is less than 0.8c is a fast charge. When the load current is greater than 0.8c, we call it super-fast loading.

Precisely because the concept of 1C is a logical rather than absolute values, therefore, according to 1C slow conversion of the fast charge is a charge of relative value. Mentioned in the previous example 200mA charging current for Dell Inspiron 1420 battery 1200mAh fills slowly, but it is for the 700mAH battery fast charge.

Aware of the concept of fast and slow filling, we also need to understand the situation charger can charge the battery properly. Charger on the market can be divided into two types of constant current charger and automatic battery charger

2, constant current charger

Constant current charger is the most common chargers, nickel-cadmium batteries of the time we started to use the charger with constant current. Constant current chargers typically use a load current slow, its use is relatively simple, just put the battery in the battery can be charged storage. Note that the calculation of the charging time must be accurate.

The calculation of the charge time has a simple formula: Hour = 1.5C / load current. For example: on the charger 1200mAH hp Pavilion ZE2000 battery charge current of 150mA, then the time to 1800mAH/150mA equal to 12 hours. Of course, in many cases can not be calculated exactly the time we can choose the nearest half an hour to facilitate the chronograph. For example: charger current 160mA, right 1400mAH battery charging, then time for 2100mAH/160mA about 13 hours, instead of calculating the points.

Construction of a simple constant current charger, labor stability, is a good way to charge little effect on battery life. But it also has its limitations, we must first calculate the time, while nickel-metal hydride batteries with a capacity for growth, the constancy of the time course load required for longer and longer, the use of ’cause a number of drawbacks. Thus, in recent years, rapid charger system is also very popular

3 autoloader and quick

Fast automatic charger in these two years are always better received, he has the speed of loading, security and so on. But there are also some people have doubts about this because of the fast chargers are essentially using current fast charge to charge, the impact of these people will be scared about the life of the sony VGP-BPS5 battery. So the current situation?

Firstly need to be sure that the current charging high impact on the life of the battery is very low, and in many cases, we use fast charge and even ultra-fast load, the current load can sometimes reach 2C or higher. Mainstream is not a killer battery, the real impact on battery life is the heat capacity at high current generated during charging.

We charge the battery when using the nominal voltage above the battery voltage to make, but the battery itself, the load current produces a back EMF, it is part of the current to compensate the the back-EMF and in vain for power and transformed into heat. When the load current is larger, more electrical energy is converted into heat, charging the higher temperature. Too high a temperature on rechargeable batteries is harmful, and a slow charger with constant current, because it is slow charging, the heat generated within the control box, so no need to take special measures. But in the ADF rapidly using a fast charge current will generate high temperatures. Therefore, currently available rapid charger automatically have adopted various methods to reduce the load when the temperature, typically using the cosine law is not a constant current load, but it has intensity current wave of cosines The changes that will reduce heat buildup, thus controlling the temperature within a certain range. Since this type of charger is no longer using the constant load current, charger current is constant in the past, a clear distinction between

To use the quick charger Another problem is that when the charging time is counted if you forget to stop after charging damage the toshiba PA3284U-1BRS battery charger to be much larger than the current slow constant overload resulting damage. Therefore, to solve the problem of overload, voltage fast charger is generally used as the France and other methods to determine the slope to determine if the battery is nearly full, these chargers are used to control the circuit, or IC chip to perform this task. When the battery is almost full, the control circuit will automatically slow charge mode, trickle charge the battery. Used trickle charge current of the battery on the advantages are obvious, the one mentioned above, can trickle charge the battery charge very complete, followed by anxiety billing question, if the maximum use of chargers such advantage n is not obliged to go computing time. The specific use to consult the manual for instructions specific to avoid improper operation.

It is a branch of the fast charger is ultra-fast charger, line battery charger applications of these small, design, structure and processes are very complex, so the prices are quite expensive.

On special occasions, people need in a time short of a good rechargeable apple M8403 battery, which requires the use of ultra-high speed charger. As the ultra-fast charger requires a lot of load current, and some have even used the 2C-3C load current, the heating problem is particularly serious, just by using the cosine wave accusation is not enough, both of these chargers adopted a cosine wave in the post – Insert a landfill very short this approach. This approach can reduce the back-EMF due to the consumption charge current generated by the accumulation of heat, so an additional control of temperature.

4, discharge

Were introduced to a memory effect of rechargeable batteries, we also know that when the memory effect gradually accumulated, would be the actual use of the battery capacity has dropped significantly. To reduce the memory effect caused by the negative role of an effective discharge. In general, nickel-cadmium batteries because of the memory effect most obvious, it is recommended to use 5-10 times after repeated charge for a discharge, while nickel-metal hydride memory effect of batteries must be better, you can charge made after the use of 20-30 times per discharge.

On the market a number of high-end loader to carry out their functions, but the vast majority of feeder medium and low Aspire 3000 battery is impossible to perform functions, then how can we do? To understand the principles of the landfill, we can also try to have the battery discharge.

We already know that nickel-cadmium batteries and nickel-metal hydride battery nominal voltage is 1.2V, but in fact, the battery voltage is a change of values, the adequacy of electricity around the volatility of 1.2 V or more. Generally fluctuated between 1V-1.4V, different brands of batteries vary in regularity, the fluctuation of voltage is not fully consistent with

Discharge the battery is to use a low current discharge, the battery voltage falls slowly to 0.9V-1V between the discharge should stop. Not recommended under the discharge of the battery of 0.9V, it will cause excessive discharge, the battery is not irreversible damage, said on a rechargeable battery is not suitable for use in appliances to the remote, because the use of the remote being very low for a long period of the remote is easy to use cause an excessive discharge. Following a performance of the VGP-BPS9A/B battery, you’ll be pleasantly surprised to find the battery capacity has recovered its original level, so when the battery capacity has been found to decline, it is preferable to a landfill.

His discharge the battery so there is easy way to make a small bead like electric charge, but you must use the meter to monitor voltage changes, to avoid excessive discharge.

For the shipper to choose the shipper to choose fast or slow charger with constant current, which depends mainly on the orientation of their own use. Such as the frequent use of digital cameras and other equipment from a friend, you should choose a quick charger, to meet time requirements, and even ultra-fast charger, you can buy, but only the use of portable devices listening as a friend, a constant current charger will be able to meet the needs of

In controlling the correct charge and knowledge of the landfill, everything will be better able to use their own rechargeable batteries. Please do not adhere rigidly to a fast charge.

In recent years, electric vehicles extraordinarily rapid development momentum, and many people like the green of this convenient means of transport, use of electric vehicles, according to incomplete statistics, the number of people in the country were put on a million, but 90% of users experiencing the same problems six months after the use of electric cars, cars Pao Bule how we should load – is a sharp decrease in Laptop battery capacity. This is the commitment of the distributor of origin: Our cycle battery life of up to two years, replacing the battery for one year if there are quality issues, the battery is completely different for a half – year began to age, so most consumers are looking for distribution operators to replace the battery.

Dealers spend a lot of energy, time tested the battery and the battery is no big problem, they put the drums a little maintenance, maintenance of back to consumers may be near the battery looks the same problem, cars Pao Bule How much we should charge in order to avoid complaints. In no other choice but dealers will be issues with battery manufacturers, battery manufacturers, but they are unable to explain the difficulties the actual design and the battery charge-discharge cycle tests indicate that the cycle of life is indeed more than three years when the production process in strict compliance with quality control may be why much of the battery will be after six months of aging? Return rates rise sharply? In the end that broke our batteries?

To this end, I visited a number of professional skills of experts in cell research and academics, including Shenzhen map of America was the inventor of the shipper frequency pulse Jiang Haiqing us said: “Batteries not misuse, but poor support.” The IBM 40Y6799 battery is the source of premature aging cheap charger, this charger is simply to accelerate the aging batteries.

I survey also revealed that: At present, many manufacturers of chargers blindness in the pursuit of short-term benefits of price competition “lowest price best” To this end, they are so reduce production costs for shippers to use some electronic components at low prices, and a simple constant current, constant voltage, the charge mode of maintenance of three “low” to meet market demand for the acceptance of so-called consumers to increase product sales and corporate profits, Who would have thought that such low-power chargers, battery low now is the acceleration of the root causes of cellular aging.

Why is this so? First, let’s look at the work of the lead acid battery loading and unloading process: lead acid battery charging and discharging processes of electrochemical reaction is the process of charging, lead sulfate to form lead oxide, discharges of lead oxide is reduced to lead sulfate. Lead sulphate is very easy to crystalline material, when the Dell Inspiron B130 battery electrolytic solution of sulfuric acid concentration of lead is too high or too long a period of inactivity when the static lead sulfate will “take as a group” for form small crystals, which lead sulphate small crystals of lead sulfate and attract around like a snowball that the inertia of the formation of large crystals of sulphate of lead crystal after the small current at low voltage , on the basis of pricing, not only reduces the lead oxide can not be recycled, but will also speed up the deposit attached to the plate electrode ON, which causes a gradual decline of the working area plate electrode (which is also a low power, low current load-lead low-grade battery charger acid to accelerate the root causes of aging), this phenomenon is that people are called sulfate, which is often said aging. Then the battery capacity will decrease gradually until it can not be used. When the lead sulfate will also attract a large number of stacking of lead particles during the formation of conducting sticks, through positive and negative plates of lead sticks between the bridge and cause short-circuit the battery. If the electrode surface or seal molded case has several cracks, crystals of lead sulfate builds up in these cracks and produce tension expanded and eventually burst into the washer or break the shell, causing the hp PP2182D battery can not repair the physical damage.

Second, this low cost charger constant voltage phase of post-gas analysis very serious (that is, a serious loss of water), it directly affects the cycle life of lead acid batteries, This phase of the load current is smaller reaction combination plate is not full access to the runoff phase responsible for the reference method to a sample of high precision is not caused by the battery at an advanced stage of severe dehydration , which can exceed 20% loss of water, charging the latter part of the rapid increase in temperature above 40 degrees above normal, the sharp increase in self-defense, even if the battery is fully charged, the charger can not be filled after the bifurcation load, so that after 180 charge cycles, the battery in the group inevitably arise between the voltage of the single cell capacity and the level of difference 260 cycles, after a decline caused premature battery capacity, aging, damage.

To correct the dehydration and sulfate battery problem, Shenzhen, pulse charger inverter card America was repeated for several years of routine testing that uses non-symmetrical micro-tech digital control, monitoring real-time voltage battery and the current changes, dynamic load frequency adjustment, the use of specific impulse, so continue to organize, activate the sony VGP-BPS5 battery plates so that the plate has always been to maintain a “status” clean, ensuring that each count of the best. America card was also set up internal charger substantially the value of the instantaneous frequency high voltage current pulse can effectively remove the sulphate to clear the circuit, so that regeneration to restore the crystals of lead sulfate in the oxide lead to repair old batteries, semiconductor physical terms, as long as sufficient if the high voltage breakdown of an insulating layer may be, once the insulation was ventilation, lead sulfate of thickness will be rendered conductive state, the strong current under the action of oxidation-reduction re-generate the lead and sulfuric acid, to participate in the electrochemical reaction. If the pulse width short enough support, we can ensure that low-cost power generated in no time under the conditions of the analysis of the breakdown of gas crystals of lead sulfate to do so without compromising battery According to the principle of using the elimination of sulfate impulse to restore the battery capacity, so that the normal battery to extend the cycle life of more than twice the results.

America card was such a pricing method can not only reduce water loss and prevention of cell aging, but also repair old batteries to improve performance of low temperature discharge. Finally, I again appeal to the user being aware of their method of charging fees to save money for themselves, but also for the country to conserve energy to reduce lead acid batteries on the environment caused by pollution to make a contribution.

Battery industry is another important component of the energy sector is the economic development of a new hot spot in the national industry and relevant international battery, drawing manufacturers to increase investment in China, Chinese lead-acid Laptop battery industry has developed rapidly become the world’s largest exporters of lead acid batteries. And the power, transport, development of information industry is closely tied to the truck automotive and other transportation system and large-scale power supply without interruption in a dominant position.

However, with the continued development of industrial lead-acid batteries, energy consumption continues to increase rapidly in the environmental problems that result are becoming increasingly serious, especially the processing and recycling of waste batteries to become a major problem. At present, China is actively pursuing the circular economy, waste batteries can be recycled to 90%, but the industrial policy of China does not waste battery recycling a good development space, has resulted in their becoming long-term problem bottleneck in the development of China Battery. In order to make businesses more understanding of the lead acid battery technology battery recycling process, “Chemical Physics power supply system, an interview with Merloni engineering design-related trading company responsible person details about the used lead acid IBM ThinkPad X60 battery recycling technology processes, applications and perspectives.

Market demand is the fundamental industrial development

Q: Melloni in China over the past three decades, a growing development in the location, please tell us about development in China?

A: The design of engineering and trading company Merloni Merloni Group, a subsidiary of Italian engineering. Founded in 1973, is engaged in export and transfer of technology and patents, the Italian professional society, customers around the world. Especially in the design, establishment of an industrial production line has a wealth of experience has now been established in 23 countries around the world more than 100 production lines and factories. Beijing and Shunde in China, Russia and Moscow Lippe Rizk has offices in Switzerland to build a branch. China has established 43 projects, six are joint ventures. Its scope of environmental protection, construction materials, industrial electrical and mechanical, electrical, automotive and electronics. It is from the mid-80s on the Chinese market, and to do is export of household appliances technology transfer of production from 2000, Italy has lead to acid Dell Latitude D510 battery recycling appliances and processing technologies, the rapid development of China lead acid battery industry, In 2006, the internal promotion of new environment-friendly energy sources – cars, trucks have used the recycling of lead acid batteries and renewable raw materials, production, processing and recycling.

Q: Melloni aggressively promote lead-acid battery recycling technology process, and the application of this technology in China, what happened?

A: Lead-acid battery recycling technology transformation in China has broad prospects for development. With the automotive, telecommunications, electricity, rail transport and the rapid development of automobiles, motorcycles, electric vehicles, the use of railways, military use, fixed use, traction, storage of the energy and emergency power supply seamless lead-acid with the growing demand for battery, domestic annual consumption of lead from 35 to 40 million tonnes. A period of time after the use of lead acid batteries need to update, at present, produce various types of waste lead-acid batteries per year is around 5000 ~ 60 million euros weighing approximately 30 million tonnes. With the new demand growth in the farm, the number of discarded lead-acid batteries is expected to increase.

Currently, in Europe, the United States, Japan and other developed countries, lead-acid hp Pavilion dv8000 batteryusing the recycling rate of 90% or more, while only 60% of our country, and a number Small businesses are mainly engaged in lead-acid batteries, there are a large number of lead, after its abandonment, if used correctly, will be enough on the environment in secondary pollution. China has now been done, but the technology is immature, the future of this technology there is a great improvement, space development. Recovery of post-processing technique back easily leads battery recycling low utilization rates. The State has adopted policies to encourage and support large-scale manufacturers of battery recycling used batteries, which are the development trend, and we have the technology, just follow the market demand to meet business needs.

Conduct waste battery recycling and reuse acid lead to resource conservation, enhance environmental protection and implementation of sustainable development strategies, of great importance. The State shall promote environmental protection, both to support the protection of the environment, but also a shortage of galena to save resources for lead acid battery manufacturers with raw materials is conducive to economic development circular.

Lead-acid recycling efforts cells enter the heights of

Q: Currently, lead-acid battery recycling technology process, there are many, may I ask our technology to recover after the sony VGP-BPS5 battery is to know how?

A: The lead acid battery technologies, including battery crushing, washing, sorting, desulfurization, smelting, refining and bullion and other technologies, can be summarized as mechanical grinding, separation water, chemical desulphurization and melting furnace short. All processing plants to achieve low emissions, low pollution, low power, high efficiency in solving the pollution problem of used batteries at the same time, established a recycling, environmental protection and efficiency Battery model waste of industrialization.

Lead-acid battery recycling technology for waste treatment is Merloni Company with years of experience and outstanding technical R & D capabilities and creates. Compared to conventional treatment, which reflects many advantages: the batteries used in broken steps, installation of two broken hammer, preventing the unit from breaking and the maximum size of material, the process for next step separation has created a good basis for the grid plate can be cleaner and more deeply with other oxides and plastic components for separating, in the broken material sorting system, equipped with two sets of hydraulic separation device in May a greater degree of recovery of lead metal, the recovery levels of residues of lead in plastics could be reduced to 1.5%. At the same time, Polypropylene, would be fully and thoroughly cleaned, waste lead-acid batteries to separate the plaster in the melting pot before being required to perform specific chemical desulfurization processes, the use of sludge added the material of lead carbonate, so the mud Lead All sulfur can be converted to another use of renewable raw materials, thus reducing emissions of sulphides in the fusion process, recycling of water from the factory effluent wastewater has been to concentrate, non-polluting, emissions of NO.

Q: What is our service model in progress?

A: Because each resource area batteries are limited, so we only have an office in Beijing to provide services to clients across the country. We lead products of toshiba PA3465U-1BRS battery acid, transfer of technology and equipment. Domestic customers include windsurfing, camels and so on. In Europe and the United States and the Middle-developed countries and regions, North America, Europe, 95% recycling of waste batteries, most of whom are from the production of lead battery manufacturers of acid complete and the project has received strong government support. Believe that China will become more and more companies in the recycling of used lead-acid batteries in the past.

With the development of new energy in the world

Q: It is understood that we are implementing a turnkey project, specifically how the turn-key projects like?

A: Melloni Design AG hopes that the transfer of technology, advanced technology, training of local staff, enabling its customers to participate in project development.

Turnkey project, once completed, the plant or project ownership and project management to complete the construction and the investment side, by its begun to enter the formal production and operational phases.

Turnkey construction is completed, there was still a large number of monitoring services. One is training to employment. Highly specialized equipment, use and maintenance have many requirements. Secondly, regular professional maintenance. Regular professional maintenance is only focused on certain key equipment, and the board should be on building contractors and other professional societies. 3 is a major change. Many chemical type of material life are 5 to 10 years while the useful life of equipment can usually 20 years or more. Therefore, the process will require the use of different materials based on the life and status of a replacement.

The spirit of the technology to create a green life in entrepreneurship, with the help of advanced technology and equipment, strong technical force and scientific management mode, became China’s handling used lead acid recycling company batteries a marvelous work, working to “protect the battery from the environment, man-made clothes,” the target for renewable energy in China and contribute to the development of environmental protection.
