Can the 12-volt battery of an electric vehicle power the car?

When the battery on the car is out of power, it is not allowed to use the 12-volt battery of the battery car to power the car. This is mainly because the output current of the electric car and the car battery are different, and the current output by most car batteries is different. The DC voltage is 12 volts or 24 volts, but the current output by electric vehicles is basically 220 volts of alternating current.

If the 220-volt alternating current is directly mounted on the battery car with an output of 12 volts or 24 volts direct current, it is easy to cause excessive voltage and cause the battery to be broken down and burn out, or damage the car.YuanIn serious cases, it may cause the car to catch fire and so on.

Therefore, when the car battery is out of power, you need to use the corresponding charger to charge the battery first, or use other series and parallel methods to charge the car battery without a store. Especially when the battery is started across borders, it is necessary to distinguish the connection sequence of the battery cables, otherwise it is very likely to cause a short circuit during the charging process.

However, under normal circumstances, never connect the battery of the car with the external battery for charging, because if the two batteries are directly connected in parallel, if the pressure difference is too large, it will cause damage to the inside of the battery or damage the life of the battery. If it is more serious, it may even threaten the life of the owner, so it is absolutely impossible to use the 12-volt battery of an electric vehicle to charge the car.
