The reasons why electric vehicle chargers do not change their lights may involve multiple aspects, and the following are the answers sorted out according to the requirements:
1. Mismatch between charger and battery: The parameter settings of the charger do not match the battery, especially when the voltage is too high, which may lead to long-term overcharging of the battery, ultimately causing the battery to lose water or be damaged, resulting in the situation where the charger remains unlit. At this point, it is recommended to replace the charger that matches the battery and check if the battery is damaged.
2. Charger or battery failure: Internal component failure of the charger: Electronic components inside the charger may malfunction, resulting in the inability to correctly detect battery status or perform flashing operations. In this case, the charger should be inspected internally and repaired or replaced if necessary. Battery failure: There may be one or more individual batteries in the battery pack that are malfunctioning, hindering normal light jumping during the charging process. Battery dehydration is also a common problem that requires battery replacement or professional repair.
3. Charging environment or habit issues: The charging environment temperature is too high: When charging in a high temperature environment, the charging voltage at the battery end may not reach the set value, resulting in a sustained high current and inability to trip the lights. It is recommended to lower the temperature of the charging environment and choose a well ventilated and cool place for charging. Bad charging habits: Long term charging, frequent charging, and charging immediately after the electric bike ride may cause the internal temperature of the battery to become too high or lose water, thereby affecting the normal flashing of the charger. Suggest adjusting charging habits to avoid overcharging and immediate charging.
Attention should also be paid to checking whether the contact between the power socket and the charger is good, whether the charger power cord is plugged in properly, and whether the socket has power and other power issues. If none of the above measures can solve the problem, it is recommended to seek professional assistance for inspection and repair.
