How Large is the Car Starting Current?

[MacBrooklyn]

Typically, the battery output current for starting a gasoline engine can reach 200-600 amps, while for a diesel engine, it can reach up to 1000 amps. Relevant information about the starting current is as follows: 1. Introduction: The starting current of a motor refers to the line current input when the motor is connected to the rated voltage and starts from zero speed. The starting current of a motor is generally 5 to 7 times its rated current. A motor's excessively high starting current can significantly impact electrical equipment and the power grid. 2. Negative Effects: If the motor's load is too heavy and it cannot reach the rated speed within a short time; or if the voltage is too low and the motor cannot reach the rated speed for an extended period; as well as if the motor is started multiple times in succession or frequently reversed, all these scenarios may cause the motor's windings to overheat, and in severe cases, the windings may burn out due to overheating.
