How much current is needed to start a car?
1 Answers
Starting a car requires 100 to 300 amps of current. Here are the specific details about how much current is needed to start a car: Engine starting current: When starting a gasoline engine, the electrical output current can reach 200-600 amps, while for a diesel engine, it can reach up to 1000 amps. Relationship between car engine displacement and current: Generally, the larger the engine displacement, the greater the starting current required. Different engines are paired with different starters, and car starters typically have a power rating between 1 kilowatt and 3 kilowatts. When starting the engine, the battery releases a very high current to ensure smooth engine startup.
