The Battery Energy Management System automatically ensures that your car has enough battery power to start the engine, based on the battery charge state and the temperature. It’s designed to be effective even if you don’t use your car for a long time.
Due to systems like traffic news memory and the Anti-Theft Alarm, modern cars constantly tap into the battery’s energy, even when not in use. If the charge level becomes critical, the system gradually shuts down the car’s non-operative consumption. It monitors the battery’s voltage level and the charging activity while driving. If necessary, it increases the idle speed slightly to enhance the alternator’s charging output. In extreme cases, very high-consumption components such as seat heating are temporarily shut down, but if you’re driving normally, this interruption is so brief that you will barely notice it.
