The invention provides an instantaneous power calculation and display method. The instantaneous power calculation and display method comprises driving power and energy recovery power. The method comprises the steps: calculating the maximum power of a driving system and the available power of a battery according to the torque limit value of a motor, and calculating the residual available power; enabling the available power of the battery to limit the maximum power of the driving system by considering the battery discharge capability, and calculating according to the battery temperature and the residual electric quantity; and calculating and displaying the instantaneous power of a braking energy recovery system according to the actual torque of the motor and the torque limit value of the motor. According to the method, the power parameters are output in real time in the form of percentage, and the specific state of the instantaneous power of the electric vehicle is reflected more accurately.
本发明提出了一种瞬时功率的计算和显示方法,包括驱动功率和能量回收功率。根据电机扭矩限制值计算驱动系统最大功率和电池可用功率,计算剩余可用功率。电池可用功率考虑电池放电能力对驱动系统最大功率进行限制,根据电池温度和剩余电量计算。根据电机实际扭矩和电机扭矩限制值,计算显示制动能量回收系统瞬时功率。本发明通过百分比的形式实时输出功率参数,更准确地体现了电动汽车瞬时功率的具体状态。
