Can a Car with Start-Stop Function Use a Regular Battery?

[DeBrayden]

Cars with start-stop function cannot use regular batteries because regular batteries pose several hazards, including shortened lifespan, rapid capacity degradation, inability to properly support the start-stop function, and potential health impacts on passengers. Below is relevant information about the start-stop function: The original intention of engine start-stop technology is energy saving and emission reduction: The system is designed to automatically put the engine into a dormant state during brief stops to achieve energy saving and emission reduction. When the vehicle stops due to traffic congestion, the driver presses the brake pedal, shifts to neutral, and the system automatically detects that the engine is idling without being in gear. At the same time, the wheel speed sensors show zero speed, and electronic sensors indicate sufficient energy for the next start. When these three conditions are met, the engine will automatically shut off. To restart, the driver simply needs to release the brake pedal, press the accelerator, or turn the steering wheel. Advantages of the car's automatic start-stop function: The principle of the automatic start-stop system is to add an electric motor to a conventional gasoline engine. When the car is stationary and the engine is idling, the engine will completely shut off. When restart is needed, the electric motor quickly starts the engine in response to the driver pressing the accelerator, engaging the clutch, or turning the steering wheel, ensuring smooth transition and reducing fuel consumption during idle time.
