Abstract: A battery system for an electric vehicle, including: a high voltage (HV) battery subsystem including a battery cell stack with battery cells electrically connected between stack nodes; a low voltage (LV) battery subsystem including a LV battery and a supply node connected to the LV battery; a DC/DC converter with a primary coil in the HV battery subsystem and a secondary coil in the LV battery subsystem, wherein the primary coil is connected to one of the stack nodes via a switch. A threshold signal indicative of a voltage at the supply node may be generated in the LV battery subsystem and may be transmitted to the HV battery system. A state of the switch may be controlled based on the threshold signal.

Abstract: A power supply system for a battery system of a vehicle is provided. The power supply system includes: a switch control unit configured to control a power switch to switch an external load; an electronic unit; a first power supply electrically connected to the switch control unit and electrically connected to the electronic unit; a second power supply; and a switching unit. In a normal mode, the first power supply electrically supplies the electronic unit. The switching unit is configured to, in a cold crank mode: electrically disconnect the first power supply from the electronic unit when a voltage of the first power supply drops below a threshold voltage; and electrically connect the second power supply to the electronic unit when the voltage of the first power supply drops below the threshold voltage such that the second power supply powers the electronic unit in the cold crank mode.

Abstract: A battery system includes: a battery management system comprising a DC/DC converter and a system basis chip; a microcontroller connected to the system basis chip to receive power from the system basis chip; and a relay driver configured to control a relay. The DC/DC converter receives power from a power source, and the system basis chip receives an output voltage from the DC/DC converter. The relay driver is connected to a node between the system basis chip and the DC/DC converter to receive the output voltage from the DC/DC converter. The microcontroller is electrically connected to the relay driver and is configured to: before switching the relay, control the DC/DC converter to increase the output voltage from a first voltage to a higher second voltage; and control the relay driver to switch the relay while the DC/DC converter outputs the second voltage.

Abstract: A bidirectional power supply system receives power from a low voltage (LV) primary power supply, providing power to a control unit of a LV board net in a first mode of operation. A high voltage (HV) board net is coupled to a HV traction battery. A DC-DC converter, in the first mode, transfers energy from the LV board net to the HV board net to power components of the HV board net via the primary power supply, and, in a second mode of operation, transfers energy from the HV board net to the LV board net to power the control unit via the traction battery. The bidirectional power supply system includes a measurement element to detect whether the primary power supply is lost, and a switching element to switch operation of the DC-DC converter from the first mode to the second mode, when the primary power supply is lost.
