15个元件组合并联，用动态规划逆序求安全系数最高的并联方式(dynamic programming backward)

根据信号的时域表达式，在matlab中求出他的自相关函数，并绘画出来(correlation spectrum)

Note that the energy-regenerative current is directly proportional to the motor speed and the braking torque. Hence, if the rider brakes his EV at a high speed, the surge current of the energy regeneration will damage the battery at the braking transient.
