The embodiment of the invention provides a mine truck braking energy recovery system and method.The system comprises a main control module and a main DC/DC conversion module which are connected with each other, and the main control module is used for collecting a brake pedal signal, an accelerator pedal signal and a brake resistor input contactor feedback signal from a mine truck control box; when a feedback signal of a brake resistor input contactor is a high level and a brake pedal signal is greater than a first preset voltage, the main control module controls the main DC/DC conversion module to enter a charging mode; and when the accelerator pedal signal is greater than the first preset voltage, the main control module controls the main DC/DC conversion module to enter a discharge mode. According to the application, the electric energy converted from the kinetic energy generated during the braking of the mine truck can be stored, and the electric energy is converted into the kinetic energy required by the acceleration of the mine truck during the acceleration of the mine truck, so that the problems of energy conservation and environmental protection caused by the fact that the kinetic energy is dissipated into the air through the braking resistor during the braking of the mine truck are effectively solved.
本申请的实施例提供了一种矿卡制动能量回收系统和方法,该系统包括相互连接的主控模块和主DC/DC变换模块,主控模块用于从矿卡控制箱采集刹车踏板信号、油门踏板信号以及制动电阻投入接触器反馈信号;在制动电阻投入接触器反馈信号为高电平且刹车踏板信号大于第一预设电压时,主控模块控制主DC/DC变换模块进入充电模式;在油门踏板信号大于第一预设电压时,主控模块控制主DC/DC变换模块进入放电模式。本申请能够将由矿卡制动时产生的动能转换而来的电能进行存储,并在矿卡加速时将电能转换成矿卡加速需要的动能,从而有效地解决了矿卡在制动时动能通过制动电阻耗散到空气中所造成的节能环保问题。
