The invention discloses a whole vehicle power control method and system for an electrified road heavy truck, and mainly relates to the field of new energy heavy truck power control. A vehicle control unit is used for controlling a DC/DC module to output interval voltage values V1, V2 and Vx; the interval voltage value is compared with the current voltage value of the battery system, and the charging and discharging state of the battery system and the working mode of whole vehicle operation are determined according to the voltage value comparison condition; switching between voltages can be shortened to be within one interval, the voltage interval difference value can cover voltage fluctuation generated by a voltage holding method, the influence of the fluctuation on the battery system is reduced in time, therefore, repeated charging and discharging of the battery system cannot be caused, and the service life of the battery system is prolonged.

    本发明公开了一种电气化公路重卡整车动力控制方法及其系统,主要涉及新能源重卡动力控制领域。本发明使用整车控制器控制DC/DC模块输出区间电压值V1、V2、Vx;将所述区间电压值与电池系统当前电压值进行比较,根据电压值比较条件确定电池系统充放电状态和整车运行的工作模式;本发明可将电压之间的切换缩短到一个区间内,电压区间差值可以覆盖电压保持法产生的电压波动,及时减小了波动对电池系统的影响,从而不会造成电池系统反复充电和放电,提升电池系统的使用寿命。
