基于FPGA的动力电池管理系统研究与开发

摘要

A battery management system has been developed on the basis of a single chip MC9S12DG128 and a FPGA.The functions of the system include data monitoring, cell Equalization,security Management .state of charge (SOC) estimation,cont roller Area Network (CAN) communications and so on.This paper introduce the features of distributed structural module in this battery pack system, CAN bus interface, and the design of the hardware and software function.%构建了基于单片机芯片MC9S12DG128与FPGA的电池管理系统,实现了数据监测、电池均衡、安全管理、荷电状态( SOC)估计、局域网(CAN)通信等功能.详细介绍了使用该系统模块的电池包的分布式结构特点,电池管理模块的CAN总线接口及硬件和软件功能设计.
