Title:
METHOD FOR TESTING STORAGE BATTERY OF VEHICLE, AND BATTERY TESTING DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/007712
Kind Code:
A1
Abstract:
A method for testing a storage battery of a vehicle, and a battery testing device (100). The method comprises: acquiring an open-circuit voltage of a storage battery to be tested and a battery feature of said storage battery (410); acquiring a discharge voltage of said storage battery when discharging electricity under a preset discharge condition (420); obtaining a voltage drop value of said storage battery according to the open-circuit voltage and the discharge voltage (430); determining a CCA parameter of said storage battery according to the voltage drop value and the preset discharge condition (440); and determining a health state of said storage battery according to the battery feature, the open-circuit voltage, the CCA parameter and a preset mapping relationship (450). That is, a CCA parameter of a storage battery to be tested is acquired by means of controlling said storage battery to discharge electricity under a preset discharge condition, and a health state of said storage battery can be quickly and accurately determined according to a battery feature, an open-circuit voltage, the CCA parameter and a preset mapping relationship, thereby facilitating a user in maintaining said storage battery in a timely manner.
