基于ARM的电动汽车制动能量回馈系统的研究

Electric Vehicle Braking Energy Feedback System Based on ARM

针对电动汽车制动能量回馈系统,提出了利用超级电容作为储能元件来实现电动汽车再生制动能量的回收利用。设计了针对NXP公司的LPC2400系列ARM,应用脉宽调制PWM控制技术,实现了电动汽车超级电容再生制动控制系统。调试结果表明,在模糊PID控制下再生制动控制器响应效果良好,而且双向DC/DC变换器的控制算法和储能系统是影响制动能量回收的两大因素。验证了系统的软硬件设计能够很好地回收电动汽车的再生制动能量。

Aiming at the system of regenerative braking of electric vehicle was put forward. The energy reclaiming scheme by using the super capacitor as energy storage element to realize the regenerative braking of electric vehicles was put forward. A kind of super capacitor regenerative braking controller of electric vehicle based on pulse-width and the LPC2400 series of ARM for NXP company. The test result indicates that regenerative braking controller based on fuzzy PID theory has better performance. And the control algorithm and the converter system of bidirectional DC/DC are two important fac- tors to influence the braking energy recovery. Thus software and hardware design of the system was confirmed to be able to recycle the electric automobile electric regenerative braking energy well.
