What is the reason for the automatic start-stop failure in the new smart car?
1 Answers
The reasons for the automatic start-stop failure in the new smart car are as follows: Battery depletion: The automatic start-stop function primarily relies on the battery's capacity. When starting the engine, the extremely high current consumes a significant amount of battery power. Therefore, cars equipped with this function use high-capacity batteries that can withstand large current surges. When the battery power is depleted to a certain extent and can no longer continuously provide the massive current required, the automatic start-stop function will automatically deactivate to protect the battery and maintain its lifespan. In such cases, replacing the battery with a new one is necessary. Vehicle temperature and other issues: The engine coolant temperature has not risen after a cold start (normally below 70 degrees Celsius); the outside temperature is below 5 degrees Celsius, or the interior temperature with heating on is below 20 degrees Celsius; the steering wheel angle exceeds 30 degrees; the driver in the front seat is not wearing a seatbelt; parking on a slope (e.g., a gradient of 10% or more).
