Method for loadings a low voltage battery for motor vehicle, involves configuring cooling device for cooling low voltage (LV)-direct current (DC)direct current (DC)-transducer and LV-battery, and operating transducer with full load

摘要

The method involves providing electrical power by a high voltage power supply such as a HV-battery (HV-B) or a plug connector (SV). A low voltage (LV)-direct current (DC)direct current (DC)-transducer (W) is configured for reducing a charging voltage of the high voltage power supply for the low voltage battery (LV-B). A cooling device (KE) is configured for cooling the LV-DCDC-transducer and the LV-battery. The LV-DCDC-transducer is operated with full load (s). An independent claim is included for device for loading a low voltage battery for motor vehicle.
