How much is the starting current of an engine starter?
1 Answers
When a gasoline engine starts, the battery output current can reach 200 to 600 amps, while for a diesel engine, it can reach up to 1000 amps. Introduction to starting current: The starting current (CCA) index refers to the minimum current obtainable under specific conditions at -17.8°C and -28.9°C. This index links the starting capability of the battery with important variables such as engine displacement, compression ratio, temperature, starting time, the technical state of the engine and electrical system, and the minimum operating voltage for starting and ignition. Starting current vs. operating current: Generally, the starting current is 20 times the operating current. This occurs when the battery is weak or not fully charged, or possibly when the under-voltage indicator is damaged. It is recommended to test the battery voltage after 25 kilometers. For a 48V battery, a reading around 50V is considered normal.
