The invention discloses a hybrid electric vehicle, a control method and device of the hybrid electric vehicle and a storage medium. The method comprises the steps of obtaining a preset first calibration value and a preset second calibration value; acquiring the current environment temperature of the power battery; performing temperature compensation on the first calibration value and the second calibration value according to the environment temperature; acquiring the charge state of the power battery, the current allowable discharge power and the maximum discharge power of the fuel battery; and if the charge state of the power battery is smaller than the compensated first calibration value and larger than or equal to the compensated second calibration value, controlling the output power of the driving motor to be smaller than or equal to the sum of the first discharge power of the power battery and the maximum discharge power of the fuel battery and larger than or equal to the maximum discharge power of the fuel battery. The first discharge power is smaller than the current allowable discharge power of the power battery. Therefore, the situation that the SOC of the power battery is continuously reduced to be too low can be effectively prevented, the SOC of the power battery can be effectively improved, and the performance of the vehicle is better.
本发明公开了一种混合动力汽车及其控制方法、控制装置和存储介质,其中方法包括:获取预设的第一标定值和第二标定值;获取动力电池当前所处环境温度;根据环境温度对第一标定值和第二标定值进行温度补偿;获取动力电池的荷电状态、当前允许放电功率和燃料电池的最大放电功率;如果动力电池的荷电状态小于补偿后的第一标定值且大于等于补偿后的第二标定值,则控制驱动电机的输出功率小于等于动力电池的第一放电功率和燃料电池的最大放电功率之和、且大于等于燃料电池的最大放电功率,第一放电功率小于动力电池的当前允许放电功率。由此,不仅能够有效预防发生动力电池SOC持续下降至过低的情况,而且能够有效提高动力电池SOC,使得车辆的性能更优。
