It is not good for the starting circuit, it is easy to overheat, and then it will cause great damage to the starter. Insufficient voltage causes the starter to react too slowly when starting. After a long time, the starting switch and wheels will be damaged, and the service life of the long-term low-voltage battery itself will be shortened.

The power failure of the car has no effect on ECU. ECU (Electronic Control Unit) Electronic control unit, also known as driving computer, vehicle-mounted computer, etc. In terms of use, it is a special microcomputer controller for automobiles. Like an ordinary computer, it consists of a microprocessor (MCU), a memory (ROM, RAM), an input/output interface (I/O), an analog-to-digital converter (A/D) and a large-scale integrated circuit such as shaping and driving. In a word, ECU is the brain of a car. There are also some rules that need to be paid attention to when the car is powered off for emergency charging. The negative terminal of the rescue vehicle must be connected with the metal part in the engine room of the dead vehicle. If it is directly connected to the negative terminal of the car, it will produce sparks. Secondly, when connecting jumper cables, the positive and negative poles must not touch, otherwise sparks will occur. Again, don't go near the car when charging.
