The invention relates to a method for calculating and displaying energy consumption of a pure electric truck, and solves the problem that the energy consumption cannot be calculated or jumps when a vehicle exchanges electricity at present. After a vehicle is powered on, the display screen (1) obtains the mileage and the current average power consumption of the vehicle from the instrument (3) through the CAN bus (2), an interval calculation mode is adopted, every time the vehicle travels for 1 kilometer as a calculation interval, and after the vehicle travels for 1 kilometer, the display screen (1) obtains the accumulated discharge amount and the accumulated kinetic energy feedback charge amount from the battery management system (4) through the CAN bus (2); the average power consumption data with the historical average power consumption of about 50km is displayed in a curve mode, the current average power consumption data calculated in real time is displayed in a straight line, the average power consumption is calculated by two groups of power consumption data received by the display screen every time when the display screen is powered on, and the average power consumption is calculated with the data before power failure. And displaying a calculation result on an energy consumption query page of the vehicle-mounted display screen. The driving behavior can be standardized, and the energy utilization rate can be improved.
本发明涉及一种纯电卡车能耗计算及展示方法,解决了目前当车辆换电时,存在能耗无法计算或能耗跳变的问题。车辆上电后,显示屏(1)通过CAN总线(2)从仪表(3)获取当车辆行驶里程,当前平均电耗采取区间计算方式,每行驶1公里作为一次计算区间,车辆每行驶1公里后,显示屏(1)通过CAN总线(2)从电池管理系统(4)获取累计放电量、累计动能回馈充电量,历史平均电耗为近50km的平均电耗数据,以曲线的方式显示,当前平均电耗显示实时计算的平均电耗数据,用一条直线显示,显示屏每次上电取上电收到的2组电耗数据计算平均电耗,并与断电前的数据做计算,计算结果展示在车载显示屏能耗查询页面。本发明有助于规范驾驶行为、提高能源利用率。
