SWITCH POWER SUPPLY, POWER BATTERY SYSTEM, AND VEHICLE
Document Type and Number:
WIPO Patent Application WO/2023/029531
Kind Code:
A1
Abstract:
The embodiments of the present application relate to the technical field of switch power supplies. Disclosed is a switch power supply. The switch power supply comprises a voltage isolation module, a voltage stabilization module, a voltage transformation circuit, a first switch and a power battery monitoring module, wherein an input end of the voltage isolation module is connected to a power battery, and an output end of the voltage isolation module is connected to an input end of the voltage stabilization module; an output end of the voltage stabilization module is connected to an input end of the voltage transformation circuit; an output end of the voltage transformation circuit is connected to one end of the first switch, and the other end of the first switch is connected to the power battery monitoring module; and when the switch power supply is in a low power consumption state, the first switch is alternately switched on and off according to a received clock signal, so as to make the power battery monitoring module intermittently monitor the power battery. In this way, the embodiments of the present application achieve the beneficial effect of the switch power supply monitoring, in the low power consumption state, the power battery.
