Electric vehicle batteries should not be in a state of insufficient power for a long time, and should form a good habit of charging batteries every night. If it is not used for a long time, it should be fully charged, placed in a cool and dry place, and charged regularly (generally 10 days).

  Avoid overcharging. When the charger shows full charge, stop charging. You can't charge it overnight or even for a few days. Overcharge will cause the active material of the electrode plate to harden and fall off, resulting in water loss and battery deformation. When the battery operates in high temperature season, there are mainly overcharge problems. Therefore, ensure good heat dissipation, prevent charging after exposure to the hot sun, and keep away from the heat source.

  Avoid long-term power loss, which will vulcanize the electrode plate. It turns cool in autumn. Under the condition of low temperature, the charging mainly has the problems of poor charging acceptance and insufficient charging, resulting in battery power loss. Insulation and anti freezing measures shall be taken at low temperature, especially when charging, it shall be placed in a warm environment, which is conducive to ensuring sufficient power, preventing irreversible sulfation and prolonging the service life of the battery.
