【摘要】：在动力电池生产过程中,电池内阻和电压是最主要的测试参数。由于动力电池的开路电压较高,现有的内阻测试仪只能在电池未成组之前进行测试,测试结果和成组后实际内阻差异较大。设计了一种基于FPGA(现场可编程门阵列)的快速电池分选系统,以硬件逻辑为基础,内建有硬件乘法器,控制、运算和分选等功能均由硬件完成。硬件电路直接由FPGA控制和协同工作,以减少处理器的介入和响应及通讯时间。该系统既能测试整个电池组的内阻,又能测量其它参数如电压、阻抗等,从而可有效提高动力电池的分选效率。
[Abstract]:In the process of power battery production, battery internal resistance and voltage are the most important test parameters. Due to the high open circuit voltage of the power battery, the existing internal resistance tester can only be tested before the battery becomes a group. The result of the test and the actual internal resistance of the group are quite different. A fast battery sorting system based on FPGA (Field Programmable Gate Array) is designed. Based on the hardware logic, the hardware multiplier is built and controlled. The functions of operation and sorting are accomplished by hardware. The hardware circuit is controlled and coordinated by FPGA to reduce the interposition, response and communication time of the processor. The system can not only test the internal resistance of the whole battery pack. Other parameters, such as voltage and impedance, can also be measured, which can effectively improve the sorting efficiency of power battery.

【正文快照】： 电动汽车动力电池组的状态好坏和寿命长短在很大程度上决定了整车性能的优劣。动力电池组合应用不仅要求单体电池的性能指标达到规定的要求,对参与配组的单体电池性能的匹配也有严格的要求。通过一定的电池分选方法,在成组过程中可以检测电池参数,其中串联等效电阻(电池内阻)
