Title:
BATTERY STATE TESTING METHOD, VEHICLE DEVICE AND COMPUTER-READABLE STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2023/279762
Kind Code:
A1
Abstract:
Provided are a battery state testing method, a vehicle device and a computer-readable storage medium. A voltage phase shift between battery cells is calculated by means of controlling an inverter (200) to generate a ripple current on a battery (13), and measuring the ripple voltages of a plurality of battery cells. Furthermore, a normal analysis or another type of analysis can be performed on the battery (13) according to the voltage phase shift between the plurality of battery cells. The state of a battery (13) can be monitored and tested, such that the good battery performance can be ensured, and the service life of the battery can be prolonged, thereby improving the safety of a vehicle device.
