Abstract :
This paper presents a voltage measuring system, which based on the AVR microcontroller AT90CAN32 and one or more multicell battery monitoring integrate circuits LTC6802 used in BMS(battery management system). Gives the hardware design and the software design for serial peripheral interface(SPI) communication. The use of iCoupler technology realizes the high-speed SPI communication and its reliable isolation. The off-line test shows that the system is compact in structure, ease to expand and meet the requirements of stabilization and reliability.
