1. Never store a battery in a discharged state: Lithium-ion batteries must never be stored in a discharged state. A discharged state refers to a battery that has not been charged promptly after use. Storing a battery in a discharged state easily leads to sulfation, where lead sulfate crystals adhere to the plates, blocking ion channels, causing insufficient charging, and reducing battery capacity. The longer the battery is left idle in a discharged state, the more severe the damage. Therefore, when a battery is not in use, it should be recharged once a month to better maintain its health.
2. Regular Inspection: If the driving range of an electric vehicle suddenly drops by more than ten kilometers in a short period of time, it is very likely that at least one battery in the battery pack has a short circuit, such as a broken cell, softened plates, or loss of active material from the plates. In this case, it should be taken to a professional battery repair shop for inspection, repair, or replacement. This can extend the life of the battery pack and save costs to the greatest extent.
3. Prevent high-current discharge: When starting, carrying passengers, or going uphill, please use foot pedals for assistance to minimize instantaneous high-current discharge. High-current discharge can easily lead to lead sulfate crystallization, thereby damaging the physical properties of the battery plates.
4. Correctly determine charging time: During use, accurately determine the charging time based on actual conditions, referring to the usual usage frequency and mileage. Also, pay attention to the battery manufacturer's capacity specifications, as well as the performance of the matching charger and the charging current parameters to determine the charging frequency. Generally, batteries are charged overnight, with an average charging time of about 8 hours. If the battery is shallowly discharged (with a very short driving range after charging), it will quickly become fully charged, leading to overcharging, causing water loss, overheating, and reduced battery life. Therefore, it is optimal to charge the battery when the depth of discharge is 60%-70%. In actual use, this can be converted into riding mileage, and charging should be done as needed to prevent damaging charges.
5. Prevent exposure to direct sunlight: Do not expose the battery to direct sunlight. Excessively high temperatures will increase the internal pressure of the battery, forcing the pressure relief valve to open automatically. The direct consequence is increased water loss from the battery. Excessive water loss will inevitably lead to decreased battery activity, accelerated plate softening, and fatal damage such as overheating, bulging, and deformation of the casing during charging.
6. Prevent the charging plug from overheating: Loose charging plugs and oxidation of the contact surfaces can cause the charging plug to overheat. Prolonged overheating can lead to a short circuit, directly damaging the charger and causing unnecessary losses. Therefore, if you find any of these issues, you should promptly remove the oxide or replace the connector. 1. Activating lithium-ion batteries in electric vehicles does not require any special method; the lithium-ion battery will activate naturally while the electric vehicle is in motion. Intentionally using the commonly circulated method of charging for 12 hours three times for activation will be futile and ineffective.
