Title:
HIGH-VOLTAGE MONITORING METHOD AND APPARATUS, STORAGE MEDIUM AND SYSTEM
Document Type and Number:
WIPO Patent Application WO/2022/156805
Kind Code:
A1
Abstract:
A high-voltage monitoring method, which comprises: in response to a high-voltage monitoring request, synchronously collecting first voltage data and first current data of a power battery pack of an electric vehicle by means of a high-voltage monitoring unit; calculating a first energy value of the power battery pack on the basis of the first voltage data and the first current data by means of the high-voltage monitoring unit, and sending the first energy value to a battery management unit, wherein the first energy value is used to instruct the battery management unit to monitor the high voltage of the power battery pack. The invention further relates to a high-voltage monitoring apparatus, a storage medium and a system. In practical applications, the method can ensure the accuracy of collected data, thus ensuring the operation safety and reliability of electric vehicles.
