An electrical regenerative braking system is provided for capturing kinetic energy as electrical potential energy during vehicle braking (also referred to as a braking event). The electrical regenerative braking system captures kinetic energy from an axle of the vehicle using an electric motor to produce electrical potential energy from the kinetic energy. The generated potential energy is supplied to an energy store, the resistance of which increases as the stored potential energy increases. The potential energy stored in the energy store is used to charge the battery. An electric regenerative braking system uses a controller having a variable resistor to control the braking torque of an electric motor. That is, the controller modulates the resistance of the variable resistor based on the resistance of the energy storage such that the resistance of the variable resistor decreases as the resistance of the energy storage increases.
提供一种电再生制动系统,用于在车辆制动(也称为制动事件)期间捕获动能作为电势能。电再生制动系统使用电动机捕获来自车辆的轴的动能,以从动能产生电势能。产生的电势能被供给到能量存储器,该能量存储器的电阻随着储存的电势能增多而增加。储存在能量存储器中的电势能用于为电池充电。电再生制动系统使用具有可变电阻器的控制器来控制电动机的制动扭矩。也就是说,控制器基于能量存储器的电阻来调制可变电阻器的电阻,使得可变电阻器的电阻随着能量存储器的电阻的增加而减少。
