The invention discloses a control method for quick parallel charging of hybrid electric vehicle batteries, which comprises the following steps that: a hybrid electric vehicle determines the current parallel charging required torque according to the opening degree of an accelerator pedal and the rotating speed of a motor so as to perform parallel charging on the batteries; setting a target torque required by quick parallel charging, and setting an external instruction input switch; and when an instruction that the external instruction input switch is switched on is received, switching from the current parallel charging required torque to the target torque required by the quick parallel charging, and performing parallel charging on the battery according to the target torque required by the quick parallel charging. According to the control method for quick parallel charging of the hybrid electric vehicle battery, due to the fact that the set target torque required by quick parallel charging is much larger than the torque required by current parallel charging, the battery can quickly recover the electric quantity, the power assisting requirement of a quick acceleration motor is met, and the driving feeling is improved.

    本发明公开了一种混合动力汽车电池快速并联充电的控制方法,混合动力汽车根据加速踏板开度和电机转速确定当前并联充电需求扭矩,以对电池进行并联充电;设定快速并联充电所需目标扭矩,以及,设置外部指令输入开关;当接收到所述外部指令输入开关接通的指令时,从所述当前并联充电需求扭矩切换至所述快速并联充电所需目标扭矩,并根据该快速并联充电所需目标扭矩对电池进行并联充电。本发明所述的混合动力汽车电池快速并联充电的控制方法中,因所设定的快速并联充电所需的目标扭矩较当前并联充电需求扭矩大得多,因此,可令电池能够很快恢复电量,从而支持急加速的电机助力需求,提高驾驶感受。
