The problem of electric vehicle batteries dropping quickly after being removed and charged may be caused by various factors. The following are possible reasons and corresponding solutions:
1. Causes of battery health: Aging or damage to the battery can lead to a decrease in the efficiency of storing and releasing electrical energy. Solution: Regularly check the health status of the battery, and if necessary, go to a professional repair point for testing and battery replacement. Avoid frequent deep charging and discharging to protect battery life.
2. Charging habits and environmental temperature reasons: Frequent deep charging and discharging can damage battery life. Extreme temperatures can affect battery performance and increase power consumption speed. Solution: Develop good charging habits and avoid charging the battery to 100% or discharging it to extremely low levels. Minimize the use of electric vehicles in extreme temperatures or store batteries in a suitable temperature environment.
3. Reasons for battery vulcanization and water replenishment repair: The white crystalline substances generated on the battery plates can affect the battery chemical reaction, leading to shortened charging time and severe virtual charge. Solution: If the battery life is reduced within an acceptable range, you can try the water replenishment repair method. The specific operation is to open the battery cover, inject an appropriate amount of distilled water into each circular hole, and soak for more than 24 hours. Be careful not to add water with other ingredients to prevent damage to the battery. If the battery is severely vulcanized or the battery life is severely reduced, it is recommended to go to a professional repair point for repair or replacement of the battery.
The following points should also be noted:
Battery level display issue: Some electric vehicles may have inaccurate battery level display methods, leading car owners to misjudge the battery level. Car owners should avoid behaviors such as sudden braking and acceleration to alleviate the rapid decrease in battery life.
Self discharge situation: Electric vehicles with more intelligent functions have more severe self discharge situations. Electric vehicles that are not used for a long time should be charged regularly or the battery connection cable should be unplugged to reduce self discharge.
Driving habits and loads: Heavy vehicle loads or aggressive driving styles can increase energy consumption. Car owners should reasonably control the vehicle load and develop good driving habits to extend battery life.
