Electrode contrary, please check after charging.

1. For the newly equipped smart charger, look at the positive and negative polarity of the plug in the manual or the charger nameplate.
< br >
2, Use a multimeter to measure the positive and negative polarity of the battery car charging port.
< br >
3, if the electrode is opposite, please change the polarity, please be replaced by a professional.

4, if you can not judge, please go to the electric vehicle maintenance point by professionals to check and deal with.
The battery used in the battery car is direct current, and we usually use alternating current at home. When charging the battery, you need a device to convert alternating current into direct current, this process is called rectification, this circuit is called rectifier. (That is, the charger we use to charge, of course, there are some current limiting protection circuits in it).
If you want to send the battery's direct current back to the AC power supply circuit, you need another device to convert direct current into alternating current, this process is called inverter, this device is called inverter. (When we charge our laptop in the car, we use an inverter to convert the car's direct current into 220 volts of alternating current.)
The charger we're using doesn't have an inverter circuit, so it won't reverse power.
