摘要
以Freescale系列单片机MC9S12XS128为中央管理单元主控芯片,以智能传感器MM912J637为电池监测终端核心,设计了面向12V铅蓄电池组成的电动汽车动力电池管理系统。由于选用面向车载系统的专用芯片,系统具有较好的电池兼容特性和电气安全特性。中央管理单元中扩展了大容量存储器SD卡接口,可进行SOC估计算法的测试和监测数据的存储。
The 12VLead-acid series power batteries of Electro Vehicle are used as the monitored object,a safe end stable battery system is designed,whose central management unit is based on the Freescale MCU MC9S12XS128and the monitor terminals are based on the intellectual sensor MM912J637.Because of the application of chips specialized for electro vehicles,the system has better eletro-magnetic compatibility and electro safety characteristics.Besides,the SD card interface extended in the central management unit greatly helps the test of the SOC estimation algorithm and the storage of historical monitored data.
