Abstract

The invention provides a slave control module address automatic coding system of a battery management system. The slave control module address automatic coding system comprises a master control module and N slave control modules, the main control module comprises a parameter detection unit and a main control DO control unit; the parameter detection unit is used for detecting whether the on-line slave control modules finish address coding or not and whether the number of the on-line slave control modules is consistent with the number of the slave control modules set by the battery management system or not; each slave control module comprises a slave control DI detection unit and a slave control DO control unit which are respectively used for receiving a DI signal and sending a DO signal; the master control DO control unit is connected with the slave control DI detection unit of one slave control module, each slave control DO control unit is sequentially connected with the slave control DI detection unit of the next slave control module in series, and the DO node of the last slave control module is in empty connection. According to the invention, the address of the slave control module can be automatically coded, material normalization is realized, and the production and maintenance cost is reduced.

Description

technical field [0001] The invention relates to the field of battery management systems, in particular to an automatic coding system and method for slave control module addresses of the battery management system. Background technique [0002] With the rapid development of the new energy industry, the cost requirements for battery systems are getting higher and higher. In order to reduce costs, battery manufacturers are realizing the normalization of battery packs to minimize the types of materials that need to be used in the production process. Since the battery pack needs at least one slave control module of the battery management system to monitor the voltage and temperature of the individual cells in the battery pack, in order to achieve accurate monitoring of each cell, the battery management system needs to monitor each slave The control module performs address encoding. [0003] The existing technology is to set the address through software when the slave control modu...
