The sign of a fully charged electric vehicle battery is generally based on the green light. However, in practice, the charging time should be avoided for too long, and the charging time should not exceed 10 hours in principle. The charger does not turn the lamp when the battery is charging for the following reasons: 1. The charger current is too small, the charging time is long, and the battery cannot be effectively filled within the expected time, resulting in the charger does not turn the lamp. 2. The charging ambient temperature is too high (≥45 ° C), resulting in the battery end charging voltage can not reach the limit voltage value, the charging current is always maintained at a large value, can not be reduced to the inflection point current value, resulting in the charger does not turn the lamp.
3. The charger parameter Settings do not match the battery, resulting in long-term overcharging or undercharging of the battery, resulting in battery water loss, and the charger does not turn the lamp when charging. [Overcharge, direct water loss; undercharge, after salinization, \"thermal runaway\" water loss] 4. The amount of acid stored inside the battery is too much, resulting in poor oxygen circulation inside the battery, causing \"thermal runaway\" and causing the charger to charge and not turn the lamp.
5. Battery memory acid is insufficient, in the late use of the battery due to battery water loss, charger charging does not turn the lamp. (This case is very rare) 6. The internal short circuit of the battery causes the charging voltage at the battery end to fail to reach the limit voltage value, and the charging current is always maintained at a larger value, which cannot be reduced to the inflection point current value, resulting in the charger does not turn the lamp.
7. Poor contact with the power supply

8. When the circuit board in the dial is disconnected, it is very normal that the battery is not charged or the electric vehicle battery is not charged. What to do at this time is to replace or repair the circuit board to ensure normal contact.

Note: When charging the electric vehicle, do not randomly pull the wire, to regulate the wiring, limited time charging. Try not to charge at the exit of the corridor or at home, so as not to cause accidents.
