Electric bicycle extraordinarily rapid development momentum in recent years, almost no speed product development to catch up with the development of electric bicycles, but because the battery life issues so that each user in each charge of the battery electric vehicle up to 50 yuan, not only for the user has caused enormous economic pressure, but also the protection of the environment had a big impact. So how to improve Laptop battery life, reduce costs, improve performance problems are battery users and resellers of common interest. Select the battery repairable should meet the following criteria:
1, the appearance of the battery without distortion, leakage, fever, leakage, without battery internal short circuit, open circuit, the turbidity of the apparent electrolyte and negative phenomena such as black.
2, restoring the battery is normally not exceeding three years.
3, the terminal voltage exceeds the rated voltage above 20%;
4, while the initial capacity of the battery should be 30%.
Deformation of the cell, leakage, fever, leakage, etc., can be seen with the naked eye, short circuit, open circuit can also use a multimeter and test the capacity test, the initial load and capacity discharge of the ways you can get a more accurate figure, only the electrolyte Black muddy and difficult to verify, and now focuses on what steps to detect the electrolyte.
The first detection of a sealed IBM ThinkPad X60 battery, determine the battery without leakage after shaking the battery so that the full integration of liquid and plates, then the proportion of the electrolyte to the suction device for electrolyte see if the liquid is cloudy and dark. In case of electrolyte in black, and the plates of the battery negative have softened, and this time the battery should not be able to repair, if the electrolyte is also colored properly, you can determine the main reason for decline capacity of the battery must be caused by a plate curing, so that the battery can be repaired using lead acid batteries for electric vehicle batteries in the series of specific repair systems to repair.
After discounting the batteries mentioned above, you can begin the healing process.
Repair time based on time of use the battery, the actual situation and the initial capacity of the battery to determine the time required for the repair, the use of lead-acid battery repair the system after repair, installation or maintenance of protective device directly to the battery for the car routine maintenance. After 7 days, can be repaired using a special battery charger adapted to charge and complete discharge device for detecting the battery capacity. Note:
1, charging things must be aware that the charge voltage of the battery must not exceed 1.2 times the rated voltage.
2, determine the effectiveness of rehabilitation, it is necessary to repair or repaired before the initial state of the test Dell Inspiron 1420 battery (the first non-healing, not a first charge-discharge cycles of recording capabilities) to charge and discharge to see if the initial capacity of the obligation to repair can not be blind to the repair operations to prevent half of things, electricity, achieve the desired effect repairs.
The battery in the process of repair issues that require attention to the repair while the battery does not become an industry, but work to repair the battery has been there. Many manufacturers of batteries within the battery warranty to back to back to “repair or older, to occur, put the battery back through the service provided to the user, to improve battery life effectively, reduce scrap rates, reduce battery manufacturers part of the reason for the alleged losses.
1. This set a new distribution group
After back to back, battery, battery manufacturer to charge and discharge test on review are often more than 50% of the battery does not meet the conditions of the batteries back to back. The reason is the battery in the thread group, the individual cell lag behind the formation of functional decline in the overall group of cells caused by the whole group back to back.
2, the removal of sulfide
Using specialized equipment, the hp F4812A battery to eliminate the hardening treatment. There are two kinds of resources here, there is a high voltage at high load current pulse through the elimination of a negative amount of sulphide block wear. This method is fast, fast, but the impact on battery life is relatively large. Another method is to use low currents up to 8KHz frequency on the use of the method of large crystals resonance solution, this method is slower restoration, repair effects are better, but the recovery time relatively long, often 120 hours or more. Test data show that there is no future for the recovery of 60% additional battery capacity more sulfur there are about 2 / 3 of the pile can reach 60% of capacity, more although 35% of battery capacity can reach over 80% of capacity.
3, install the pulse generator in parallel with the battery on the pulse of the battery maintenance
This method of repairing the battery more slowly, but due to many years in maintenance, so if there is no over-discharge the battery for continuous use, the battery is often the complete elimination the possibility of cure.
4, a comprehensive repair method
If the test battery used on a regular basis, timely more sulfur and pay only a single battery charge, new distribution group. After taking these approaches, the average life expectancy of the battery will be greatly improved. Regular maintenance of the service is big enough, do not wait for the battery due to water loss and hardening of the positive impact of the repair plate injuries later. In this way, can greatly extend the battery life. Once the battery of severe dehydration and healing after injury compared to the positive plate is relatively large. Therefore, it should be in the positive plate injury in a long time before the battery properly maintained. Preventive measures taken by the redesign of the method is more effective than the methods to remedy the situation.
