In the automotive market, a multitude of buck-converter ICs enable automotive power engineers to achieve low quiescent current. This effort will help extend battery runtime, especially in applications like infotainment systems that will require standby-mode power coupled with a compact solution. Buck converters also enable a reduced external component count, reducing system cost.
The complete system consists of three components:
- Battery-management-system (BMS) control module (see TI HEV/EV BMS).
- Great Wall Motor (GWM) technology.
- Quiescent-current control module (QCCM): There’s a patent for a vehicle quiescent-current control method, system, device, and computer readable storage medium, and another patent for a control device for quiescent current of automobiles.
