Document Type and Number:
WIPO Patent Application WO/2020/215233
Kind Code:
A1
Abstract:
Disclosed in the present application is a sleep circuit of a vehicle-mounted charger, which is applied to a vehicle-mounted charger control system and which comprises a first filter circuit, a second filter circuit, a signal input circuit, a resistance detection circuit, and an intermediate circuit: the first filter circuit and the intermediate circuit are connected; the intermediate circuit and the second filter circuit are connected; and the intermediate circuit comprises a first conducting branch, a second conducting branch, a third conducting branch, a fourth conducting branch, a first port, a second port, a third port, and a signal access port. The second port is grounded, one end of the signal input circuit is connected to the intermediate circuit by means of the signal access port, the other end of the signal input circuit is grounded, one end of the resistance detection circuit is connected to the signal input circuit by means of the signal access port, and the other end of the resistance detection circuit is connected to the first port. The present application integrates a vehicle control device in a vehicle-mounted charger input control and guidance circuit into a vehicle-mounted charger control system, which lowers the overall costs and strengthens reliability.
