will not
The charger input terminal of the electric vehicle is connected to 220 volts AC, there is a neutral line and a live line, but it is not differentiated, and it can be connected at will. The output end of the electric vehicle is direct current, there are positive and negative points, positive and negative poles can not be connected wrong, wrong connection is short circuit, will burn the charger and so on. Electric car charger has no zero wire, there is no wrong connection problem, zero wire can be randomly connected, will not damage the charger.
The wrong charging port of the electric vehicle charger makes the positive and negative terminals of the plug-in port opposite to the positive and negative terminals of the battery connection port, resulting in short circuit of the line, which will generate huge heat and instantly burn out the charging port.
Therefore, electric vehicle manufacturers pay special attention to this hidden danger in the design, so as to require the use of special chargers.
This maximizes the avoidance of safety accidents caused by incorrect charging port insertion.
It'll burn the charger's resistance, and some of the electrical components that power it. When the charge is reversed, there is a lot of current flowing through the battery and the charger, so the charger is burned out.
< br >
Because there is a lot of current flowing through the battery and the charger when the charging is reversed, the charger is burned out. Because the battery current is too large, it will heat violently so that the plate swelling damage, and even fire
Principle comes from, power supply?? Must be separated from ten and one, the problem of principal and vice, so pay attention to safety when using electricity,
The positive and negative connections will burn the capacitor in the battery.
