1, the charger charging is not bright electric car charger failure: electric car charger electric car charger failure, which is generally manifested as the internal components fall off or damage, so that the charger can not normally jump light, or even can not charge, causing the charger has been showing a red light. For such a case, you can only choose to replace the new charger, rather than repair, because the charger is more troublesome to repair, and it is easier to cause problems again resulting in overcharging of the battery. In addition, there is also a point to note that replacing the new charger needs to match the consistency of voltage and current.

2, the charger current is too small, the charging time is long: the battery can not be effectively filled within the expected time, resulting in the charger does not turn. The charging environment temperature is too high, 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 and so on.
The charger of the battery car will not be bright for a while, and the battery may not be short of power, and the voltage will reach the maximum value for a while. It is also possible that the battery is aging, charging fast and discharging fast, and there is no electricity after use. Battery aging, the battery is prone to such problems after 1-2 years of use, if the quality is poor, it is easier to break. Battery or charger connector loose or dirty, charger damaged.

Electric car charger charging heat automatically does not charge, electric car charger does not work for three reasons:
First, check whether the line is broken between the charger transformer and the charger output port. If it breaks, replace the broken part of the line can be.
Second, turn on the charger and see if any capacitor is missing. If it falls off, solder it back on with a soldering iron, taking care not to reverse the positive and negative ends.
Third, check the output voltage of the battery, if it is not 48 or 60V, and the resistance is very large, it means that there is a broken connection inside the battery - welding or fusing, open the battery box, and connect the broken line.
