Some methods of battery maintenance

Battery/storage battery is the power source of electric bicycle, but also a kind of consumable products, and the price is high, so keep the Maintenance Free Battery in good working condition, prolong its service life, whether from the point of view of environmental protection or economic, there is a great practical value. The following are some maintenance methods of the battery:

1. Newly purchased electric vehicles should be fully charged before use. Because many electric vehicles have been shelved in shops for several months or even more than half a year, they must be fully charged before use. It is best not to use them immediately after full charge, and they need to stand for about ten minutes.

2. The battery is taken down to charge. When the device is installed, the Maintenance Free Car Battery should be firmly installed on the electric bicycle to prevent the battery from being damaged by vibration when riding. Do not throw, roll, or weigh the battery during handling.

4. Never let the Maintenance Free Lead Acid Battery in a state of low power for a long time, and to develop a good habit of charging the battery every night. It should be filled with electricity, placed in a cool and dry place, and charged regularly (generally 10 days).

5. When the electric bicycle is just starting, it is necessary to use the foot (without foot, you can push the bicycle with your foot) to assist the starting. When going uphill, use the foot to help the electric bicycle go uphill, so as to avoid excessive discharge current and damage the battery.)

6. When riding, it is necessary to pay attention not to let the battery overdischarge. After the battery discharge to the termination voltage, continue to discharge is called overdischarge. Overdischarge is easy to cause serious power loss of battery, which greatly shorten its service life. So the battery should be used to avoid the depth of discharge, do shallow discharge frequently charged, its better to generally charging the battery when discharge depth of 50% .

7. Electric bicycles are generally equipped with undervoltage protection function, when the battery power display only one show light, should turn off the power, then use foot to move. And to charge the battery as soon as possible.

When storage battery discharge to the end of the voltage, the internal resistance is large, electrolyte concentration is very thin, especially the plate hole and the surface is almost in neutral, over discharge internal resistance has a tendency to heat, volume expansion, discharge current is large, obvious heating and even heating deformation, then the concentration of lead sulfate is particularly large, the possibility of survival dendritic short circuit increases, Moreover, at this time, lead sulfate will crystallize into larger particles, that is, irreversible sulfation will be formed, which will further increase the internal resistance, and the charging recovery ability is very poor, or even irreparable.

Battery should be used to prevent over discharge, take the "undervoltage protection" very effective measures. In addition, due to the electric vehicle "undervoltage protection" by the controller control but some other equipment outside the controller such as voltmeter, indicator light and other power consumption appliances are directly powered by the battery the supply of power is generally not controlled by the controller, electric car lock switch once closed began to use electricity. Although the current is small, if a long discharge for 1-2 weeks, there will be a discharge. Therefore, do not open the lock for a long time, and turn it off immediately when not in use.

9. Prevent the battery from discharging with large current for a long time, which will greatly damage the internal structure of the battery. It is recommended that the owner should not start for more than 5 seconds each time. It takes two consecutive starts with 1015 seconds between them.
