1. Correctly determine charging time: The optimal charging time for a battery is when its depth of discharge reaches 60%-70%.
2. Strictly avoid storing batteries in a discharged state: A discharged state refers to a battery that has not been charged promptly after use. Storing batteries 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 maintain its health.
3. Avoid high-current discharge: When starting an electric vehicle, carrying passengers, or going uphill, use pedal assistance to avoid sudden high-current discharges. High-current discharges easily lead to lead sulfate crystal formation, damaging the physical properties of the battery plates.
4. Prevent exposure to direct sunlight: Excessively high temperatures 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 inevitably leads to decreased battery activity, accelerated plate softening, and fatal damage such as overheating, bulging, and deformation of the battery casing during charging. 5. Avoid Overheating of the Charging Plug: 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 these issues are observed, remove the oxides or replace the connector promptly.
6. Regular Inspection: If the electric vehicle's range suddenly drops by several kilometers within a short period, it's highly likely that at least one battery in the battery pack has a short circuit due to a broken cell, softened plates, or shedding of active material. In this case, promptly take the battery to a professional battery repair shop for inspection, repair, or replacement. This can extend the battery pack's lifespan and minimize costs.
