Reasons for Engine Energy-Saving Auto Start-Stop System

[VanAngelo]

Below are the related reasons for the engine auto start-stop system: 1. Low battery charge: When the vehicle has not reached the ideal operating state and the battery charge is too low, insufficient voltage will cause the auto start-stop system to not work. This is because during engine shutdown, components like the engine cooling fan and in-car air conditioning require power to operate. Engine coolant temperature being too high or too low can also prevent the auto start-stop system from functioning. 2. Excessive temperature difference between inside and outside the car: When the vehicle has not reached the state set by the driver (such as when the air conditioning is on in summer), if the engine is turned off, the air conditioning compressor will not work. Once the temperature inside the car differs too much from the set temperature, the auto start-stop system will restart the engine. 3. Low-speed driving: In other situations during low-speed driving, such as when the speed does not reach 5km/h after starting, or during repeated acceleration and deceleration with speeds below 15km/h.
