Abstract

The embodiment of the invention provides a testing device and method for a battery management system, and a storage medium, and belongs to the technical field of testing of battery management systems.The testing device comprises: a CAN board card used for reading an SOC value and an SOH value stored in the battery management system; a single board card used for simulating the voltage of the single battery for the battery management system; a current board card used for simulating charging and discharging current for the battery management system; and an upper computer which is connected withthe CAN board card, the single board card and the current board card, and is used for controlling the work of the CAN board card, the single board card and the current board card so as to complete thetest of the battery management system. According to the testing device and method and the storage medium, whether the battery life prediction function of the battery management system is normal or not can be tested through simple devices and steps.

Description

technical field [0001] The present invention relates to the technical field of testing battery management systems, in particular to a testing device, method and storage medium for battery management systems. Background technique [0002] Battery aging is a long-term gradual process. The battery life SOH represents the ability of the current battery to store electric energy relative to the new battery. It expresses the state of the battery from the beginning of the life to the end of the life in the form of a percentage, and is used to quantitatively describe the performance of the current battery. state. At this stage, the mainstream battery life SOH is estimated and calculated through battery capacity decay. Whether the battery capacity decay prediction algorithm is accurate and reliable requires testing and verification of battery life prediction. [0003] The current verification method mainly uses the charging and discharging cabinet to cycle charge and discharge the b...
