1. Timeliness of charging: (1) The battery is generally in a charged half-charged state when leaving the factory. When riding for the first time, it is best to fully charge the battery, because self-discharge will reduce the charge of the lithium-ion battery, and the active material in it can be activated. (2) Do not run out of battery power every time you ride, because over-discharge can cause great harm to lithium-ion batteries. Long-term over-discharge will reduce the battery life by 3 times. At least, when there is a low battery warning during electric vehicle riding, you must stop riding decisively and charge the lithium-ion battery. 2. Timeliness of charging: (1) Lithium-ion battery is effective at any time, even if there is 50% power before charging, it does not matter. This is because it is different from Ni-MH battery, which has a memory effect. The lithium-ion battery does not. (2) Don't overcharge. When the charging completion indicator light is on, stop charging. 3. Charging to make up for self-discharge: If the battery is not used for a long time, it must be charged once within 60 to 90 days, because the best storage state of lithium-ion batteries is half-electric storage (that is, 40% to 60% of the nominal capacity of the battery) We understand that the maximum voltage of a lithium-ion battery is 4.2V. Therefore, the storage voltage is preferably between 3.8V and 3.9V. At this time, the capacity is basically half. 4. Original charging equipment: try to use the original lithium-ion battery charger to charge. The original charger has strong supporting performance and moderate charging rate. Now there are some fast charging piles. It is recommended not to use too much. Use it once or twice during the year. excusable. Excessive current charging will also cause greater damage to the internal structure of the battery. 5. Temperature environment during storage: The temperature environment of polymer batteries is relatively wide, ranging from -20°C to 45°C, but in fact the most suitable temperature is room temperature. From the perspective of aging, temperature may be an important reason for the gradual decline of lithium-ion battery capacity. For countries like our country with large temperature differences, the northern region must develop low-temperature-resistant lithium-ion batteries, while the southern region must develop high-temperature-resistant lithium-ion batteries. 6. Strictly follow the precautions in the manual: When the lithium ion battery is not in use, it should be placed in a cool and ventilated place to prevent high temperature and humidity. Try to prevent riding on rainy days. Even if you are riding, you must take good care of it. water. The reasons why the battery cannot be charged can be divided into internal reasons inherent in the battery and external reasons for the battery to perform charging.
