  • Auxiliary power supply system for high power loads in a hybrid/electric vehicle
    Patent number: 11332014
    Abstract: An apparatus includes a first interface a second interface, a third interface and a converter. The first interface may be configured to exchange a high-voltage signal with a high-voltage battery of a vehicle. The second interface may be configured to receive a first low-voltage signal from a source external to the vehicle. The third interface may be configured to present a second low-voltage signal to a power rail of the vehicle. The converter may be configured to (i) generate the high-voltage signal by up-converting the first low-voltage signal while in an up-conversion mode to recharge the high-voltage battery of the vehicle and (ii) generate the second low-voltage signal on the power rail by down-converting the high-voltage signal received from the high-voltage battery while in a down-conversion mode.

  • Auxiliary power supply system for high power loads
    Patent number: 10857957
    Abstract: An apparatus includes a first interface, a first converter, a high-voltage battery, a second converter and a second interface. The first interface may be configured to receive a first low-voltage signal from first power rail of a vehicle. The first converter may be configured to generate a high-voltage signal by up-converting the first low-voltage signal. The high-voltage battery may be configured to store the high-voltage signal. The second converter may be configured to generate a second low-voltage signal by down-converting the high-voltage signal. The second interface may be configured to present the second low-voltage signal to a second power rail of the vehicle. The first power rail may be electrically separated from the second power rail.
