The invention discloses a parking power generation control method for an extended-range electric vehicle. The parking power generation control method comprises the following steps that S10, a parking power generation function is started; step S20, judging whether the MP5 end selects an efficient mode or not, if so, carrying out step S21, and if not, carrying out step S22; step S21, the VCU selects an optimal oil-electricity conversion efficiency power point from the range extender efficiency Map based on the battery charging power limit value, requests the range extender to generate power, and then performs step S30; step S22, judging whether the MP5 end selects a'speed 'charging mode or not, if not, executing step S23, and if yes, executing step S24; the problems that in the parking charging process of an existing battery, the battery is overcharged, and the health and the service life of the battery are seriously damaged are solved, and the problems that the environment temperature in winter is low, the temperature of a battery cell is reduced, the battery cannot reach a full-power charging state, and the charging efficiency of the battery is reduced are synchronously solved.

    本发明公开了一种增程式电动汽车驻车发电控制方法,包括以下步骤:步骤S10,将驻车发电功能开启;步骤S20,判断MP5端是否选择高效模式,若是则进行步骤S21,若否则进行步骤S22;步骤S21,VCU基于电池充电功率限值,从增程器效率Map中选择最优油电转化效率功率点,请求增程器发电,然后进行步骤S30;步骤S22,判断MP5端是否选择“速度”充电模式,若否则进行步骤S23,若是则进行步骤S24。本发明解决了现有的电池在驻车充电过程中,会出现电池过充,严重损坏电池的健康和寿命的问题,并同步解决存在冬季环境温度较低,电池电芯温度会降低,电池无法达到全功率充电状态,降低电池充电效率的问题。
