Why does the electric vehicle battery get hot during charging? Is it normal?
1 Answers
Slight heating is normal as the battery generates heat during the charging process, but excessive heat is abnormal. Causes of thermal runaway: Charger output voltage too high. Battery water deficiency. Battery damage. Excessive ambient temperature during charging. Batteries used for over a year without water maintenance frequently exhibit this phenomenon. Irregular charging habits: In daily life, many electric vehicle users have irregular charging habits. For example: charging immediately after riding, charging in high-temperature environments, frequent charging, overcharging, etc. These practices can easily lead to electrolyte depletion in the battery, resulting in battery deformation.
