After the pure electric vehicle was started, the 12V battery suddenly died. What will happen to pure electric vehicles? Can they work normally?

Hello, no. This is equivalent to our traditional fuel. If the 12v battery is disconnected after the engine starts, the vehicle can run normally as long as it does not turn off the engine. In our traditional vehicles, the low-voltage battery is used to supply power for the whole vehicle before the vehicle starts, and the alternator is used to generate power for the whole vehicle after the engine starts. At the same time, our 12v battery is charged to ensure our 12V battery.

Similarly, in our pure electric vehicle, because there is no engine and generator, our small battery needs to be recharged. Therefore, a Dc-dc device (converting the high-voltage direct current of the power battery into the low-voltage direct current of 12V) is used to replace the traditional vehicle-mounted generator. Therefore, if the pure electric vehicle is normally electrified under high voltage, the vehicle can run normally. At this time, if 12V is out of power, hope to adopt it.
