摘　　要：CAN(controller area network)总线作为一种优秀的现场总线,被广泛地应用于智能检测系统。该文以C8051F040单片机为核心,设计了一种高精度、低价格的电池管理系统,实现了对电动汽车多组蓄电池组的温度和电压的实时监测。应用CAN总线与动力总成控制器通讯,性能可靠,开放性强,抗电磁干扰能力强,特别适用于复杂的车辆环境监测。As a kind of excellent field bus, CAN ( controller area network) bus is used to intelligent monitor system. The paper introduces a high precision, low price batter management system, it' s hardcore is C8051F040. The system can real - time monitor voltage and temperature of batter packages. It can communicate with powertrain controller by CAN bus, which has characteristic of reliable performance, open system and good electromagnetism immunity, it is specially is used to complex environment.
