Abstract

The invention provides a CMU test method, device and system, and the method comprises the steps: obtaining the information of a battery sampling chip corresponding to a to-be-tested CMU and a test demand; based on the type of the battery sampling chip, a communication protocol between a BMU simulator and the CMU to be tested is configured, and the BMU simulator is used for simulating the function of the BMU; based on the number of the battery sampling chips and the configuration information of each battery sampling chip, configuring a corresponding acquisition channel of each battery sampling chip in the BMU simulator; generating a first test instruction based on the test demand; and sending the first test instruction to the BMU simulator, so that the BMU simulator converts the first test instruction into a second test instruction according to the communication protocol, and sends the second test instruction to the CMU to be tested for testing. According to the invention, the automatic test of the CMU is realized, the test efficiency of the CMU is improved, the test cost is reduced, corresponding test instructions are generated according to different test requirements, the test flexibility is higher, and the function test is more comprehensive.

Description

technical field [0001] The invention relates to the technical field of batteries, in particular to a CMU testing method, device and system. Background technique [0002] The battery management system (BMS for short) is mainly composed of a cell monitor unit (CMU for short) and a battery management unit (BMU for short). Among them, the CMU is responsible for measuring the voltage, current and Temperature and other parameters, as well as functions such as equalization, BMU is responsible for evaluating the data transmitted by the CMU, if the data is abnormal, it will protect the battery, and also realize the management of battery power and temperature. [0003] The current battery module uses BMS integrated or split type collection. For split-type acquisition CMU, its flexibility is better than that of integrated type. In practical applications, battery sampling chips (Analog front end) from different manufacturers are often used to design CMUs. The resulting problem is the p...
