Title:
NEW ENERGY VEHICLE, VEHICLE-MOUNTED CHARGING DEVICE, TEMPERATURE MEASUREMENT CIRCUIT, AND TEMPERATURE MEASUREMENT METHOD
Document Type and Number:
WIPO Patent Application WO/2023/098521
Kind Code:
A1
Abstract:
A new energy vehicle, a vehicle-mounted charging device, a temperature measurement circuit, and a temperature measurement method. The circuit comprises: a first temperature sensor (TH1), which acquires a first analog quantity temperature signal of a positive electrode connection end; a second temperature sensor (TH2), which acquires a second analog quantity temperature signal of a negative electrode connection end; a third temperature sensor (TH3), which is provided in a housing of the vehicle-mounted charging device of the new energy vehicle and acquires an analog quantity ambient temperature signal of the vehicle-mounted charging device of the new energy vehicle; an analog-to-digital conversion module (10), which correspondingly converts the first analog quantity temperature signal, the second analog quantity temperature signal, and the analog quantity ambient temperature signal into a first digital quantity temperature signal, a second digital quantity temperature signal, and a digital quantity ambient temperature signal; and a micro-control unit (20), which corrects the first digital quantity temperature signal and the second digital quantity temperature signal according to the digital quantity ambient temperature signal. The accuracy of measuring the charging temperature of the vehicle-mounted charging device of the new energy vehicle can be improved.
