How to connect the electric car power battery connecting wire

Battery red pole note is positive, black is negative, at the same time note that the battery in the battery box is connected in series, that is to say, the positive terminal of a battery connected to the negative terminal of another battery, according to this method, the last will be left with a positive and a negative two lead wires, connected to the battery discharge port. Pay attention to one-to-one correspondence, generally left positive and right negative.　　First connect the two car positive terminal, then connect the negative terminal, this order is to prevent accidental hitch short circuit. When connecting the negative terminal, there are many cars where the negative terminal is covered by other parts and cannot be connected.

　　That can also be done by finding any metal part on the body of the car and connecting it, as the entire body is equivalent to the negative terminal of the battery. The point is to never connect it backwards.

　　Positive to negative will cause the engine computer and other parts to burn out because it is the equivalent of two batteries in series and the voltage is too high. When removing the battery cable with the fire on, remove the negative terminal first, then the positive.

　　The battery is dead resulting in the inability to start, many people have encountered this situation, especially the older car. The battery is dead for the following reasons, first of all, the battery life to, the storage capacity greatly reduced, so the car put a night not open can not start; secondly, the vehicle is placed for a long time not open, the natural discharge and lead to loss of power; there is also a situation is to forget to turn off the power equipment caused by the vehicle or vehicle failure, there is a leakage, resulting in putting a very short period of time will be loss of power.

　　So once you have a dead battery and can't get it to start, you generally call for assistance or find your own ride. Call rescue to save heart, do not need to operate their own, the disadvantage is that generally have to wait a long time, there may also be charges. If you know how to build electricity, you will save a lot of time, so how to build electricity?　　You also need to have a car with electricity, or an emergency starter power supply will work. Next get the two cars close enough together that the battery cables can reach the batteries of both cars, whichever is appropriate, either head to head or parked side by side. Then connect the battery cables, the mnemonic is positive to positive, negative to negative.
