Design and Realization of the Monomer Battery Monitor Module in the BMS
This paper presents a monomer battery monitor module in the BMS.It can collect the battery monomer voltage and temperature precisely and take appropriate measures according to different cases.It uploads the necessary data to the main controller of the BMS through the CAN bus.The realization of this module is based on the microcontroller MC9S12DP256 and the multicell battery monitoring integrate circuits LTC6802.The hardware design and the software design for serial peripheral interface (SPI) communication are given.Moreover,a thermal model of a monomer battery is built to decide the specific spots to place the thermistors or temperature sensors.The off-line test shows that the module is compact in structure,accurate and meet the requirements of stabilization and reliability.
