Like talking on the cordless handset and wait longer and longer, but also support other types of complex wireless applications, integrated power is becoming a significant demand for these products. This article will deal with the battery, battery systems and energy conversion. We are the first topic for discussion is the heart of the system: the battery. The content of the discussion include the type of battery, VGP-BPS9/S VGP-BPS9/B battery charge and discharge, as well as system maintenance, we will consider energy needs, safety considerations, costs, unit cell (cellular) number of impacts environmental, life cycle, the unit cell fixed amount. Mesh, battery and battery the battery is a chemical reaction is an inherent tension, the battery voltage is the nature of a chemical reaction, its structure or the size and battery size. If a component can produce such an inherent tension is called a “cell unit” (cell). A battery “(battery) May contain many units of batteries can be series, parallel or mixed with, and all placed in the same case in the file. In a shell “stack” (attached) in the battery or batteries in multiple units, and these units has its own battery or the battery case, then the shell pile is called “battery (pack). Applications can also use multiple battery packs, perhaps because it required power exceeds the supply capacity of a battery, perhaps to allow a battery, the other battery is charging or maintenance. Such applications may have circuits of battery management requirements of some other order in the charge cycle at different times or under different conditions of installation and removal can be performed sequentially on each battery. Cell Structure, nomenclature unit cell there are two reaction surfaces, their chemical composition is not the same, and by a chemical reaction can not afford to separate the conductive layer is not fixed separated in the reaction between the surface will be filled with electrochemical reaction of a good material, known under the name of the electrolyte in the battery the more commercial, the electrolyte is a liquid or a gum, but in some rare cells May be gas or solid. The surface reaction, there are contacts of the circuit (tabs), in which a high potential for contact materials are in contact, equipment and low potential for negative contact. Inside the the battery case there are two particular areas to the other for non-drivers, mainly the battery positive and negative of these positive will be connected to the device via a line inside the PA3399U-1BRS PA3399U-2BAS battery positive contact, the electrode be negatively related to negative contact. Since the vast majority of cells are cylindrical, so that vendors will be covered with a layer of anode material of the separation layer, then covered with a layer of material of anode, the final when they are rolled into cylindrical cells. On the other hand, if we can reduce these layered materials covered, you can make a space more battery saving square. Lead batteries of acid on the use of the square of the hull, the battery will be added in the electrolyte, and then the positive and negative electrical panels panels rotate film is fixed, and immersed in the electrolyte. What the battery? The battery using chemicals or ion exchange reaction, the energy stored in the potential field that result. For disposable batteries (or battery) that want to use the circuit operation restoration of these reactions is a thing possible or practical, but for rechargeable batteries (also known as secondary batteries) and the words, if we applied a voltage, which is more important than the battery voltage, you can restore these responses, while the energy stored in the stack, rather than removing power from the battery. Battery management is running a series of chemical reactions. Battery Why do we need management? The so-called “secondary chemical reaction” means a place in the pile of the chemical reaction between components, that is, store and release energy and thus a reaction other than a chemical reaction. secondary reaction will not be released as heat further, but with time and the life cycle (time of loading and unloading) increase, but also produce some solid, liquid or gaseous, in particular the reaction in solid impurities in the cell surface on the crystal and the burden of coverage can be used to store a page of “reaction” (reaction sites). The heat of evaporation of liquid or gaseous electrolyte lighter components, if the rate of gas production is higher than components of the A1060 M8403 battery can absorb, it will generate the internal pressure of a sealed battery, sealed battery without cause “gas leak” phenomenon, and change the combination of chemical ingredients. If we are already at full potential in a battery continue to exercise power, then the rate of secondary reactions will accelerate significantly, the battery is so-called “on-load (overload), it not only reduces the capacity of the battery storage loads, but also shorten the life cycle of the battery; In addition to the chemistry of the battery some, excessive discharge May cause the same effect. To release the pressure inside the battery may be sealed by these gases at high pressure is off, it may cause temporary or permanent damage. The battery has a “self-discharge rate (rate of self-discharge), which refers to the current supply of external loads n ‘ is not the case, the battery of its own “escape” velocity of electricity storage. When the battery is finished loading, we still need to perform maintenance or “floating” (float) charge, and the percentage rate shall be equal to the battery-discharge rate for the battery remained at full power state. Batteries are often used together in series or in parallel. If the adoption of these works, so that a slight difference between these batteries, it is possible for the chemistry of the battery some have a huge impact. Therefore, the battery manufacturers and OEMs require batteries must have the same chemical manufacturers, the time to plant, and even the number of production lot. And even a little chemistry of the battery or the need to keep all batteries. Of all the commercial batteries, manufacturers will be in the unit cell to release pressure within the structures of security to on-load situation is extremely serious, in a gas emission control. Some cells also contain components, as well as components fuse-temperature protection, which are the most common lithium-ion batteries. Choose rechargeable batteries, the chemical mechanism that will be used to select for specific battery chemistry, we must let the battery chemistry and applications of characteristics that complement each other in business applications today, it are five kinds of commonly used battery chemistry.

Traditionally, consumer products, appliances are mainly nickel-cadmium batteries, rechargeable batteries, because the nickel-cadmium batteries are a mature product, and we understand the chemical reactions of nickel-cadmium batteries. On the other hand, metals cadmium, their administration has become increasingly stringent in some areas, it must also make recycling compulsory associated with nickel-cadmium batteries is a mature product, and thus the capacity and life cycle not too much room for improvement. Compared to nickel-cadmium batteries, in terms of unit weight or unit volume density of energy storage, batteries nickel hydride provide a significant performance improvement of lithium-ion batteries in turn , went further, because its density storage of electrical energy that more than double nickel-cadmium batteries. Although nickel-metal hydride or lithium-ion chemical mechanism has its merits, but the drawback is that the circuit very sensitive to them, the lithium-ion mechanism, in particular clear that c ‘ is not only because the battery is damaged by mismanagement and electrolyte May ignite if the battery management is very important. Manufacturers will normally be an internal lithium-ion battery with a number of mechanisms for protection against defects to voltage / current is too large or the temperature is too high, and when the battery charge and / or circuit feeder between the cup In addition, most vendors will be inside the battery installed another series of special tours can be restored to provide protection. However, nickel-metal hydride or lithium-ion PP2182L HSTNN-LB31 battery power supply capacity is still smaller than nickel-cadmium batteries for more power, but can not use external power of the vast majority products, nickel-cadmium batteries is always the best choice. Alkaline batteries with rechargeable batteries as well as the shape of the main purpose is to replace these disposable batteries, although the price of an alkaline battery is about twice as much, but the battery life is concerned, the overall cost of the latter is much weaker. For the application of low current applications, they are not only the chemical mechanisms charge the most expensive, but it also has the lowest self-discharge rate. Life of rechargeable alkaline batteries in the shortest cycle of disadvantage is that if all cycles of charging and discharging, the battery is fully charged, then the type of battery can be used about 25 times.
