The invention provides a vehicle charging control method and a vehicle. The method comprises the steps that a battery SOC value, a battery temperature value, an accelerator pedal opening value and a vehicle speed value are obtained; in response to the condition that the battery SOC value, the battery temperature value, the accelerator pedal opening value and the vehicle speed value meet the low-temperature charging closed-loop control enabling condition, the available charging power and the actual charging power of a power battery are obtained; obtaining a generator power correction value according to the available charging power and the actual charging power; correcting the original target power generation power of the generator according to the power correction value of the generator to obtain the corrected target power generation power of the generator; and controlling the generator to generate power according to the corrected target generated power of the generator. According to the method and the vehicle, the charging capacity of the power battery in the low-temperature environment can be improved.

    本发明提出一种车辆充电控制方法和车辆,方法包括:获取电池SOC值、电池温度值、油门踏板开度值以及车速值;响应于所述电池SOC值、电池温度值、油门踏板开度值和车速值满足低温充电闭环控制使能条件,获取动力电池的可用充电功率和实际充电功率;根据所述可用充电功率和所述实际充电功率获得发电机功率修正值;根据所述发电机功率修正值对发电机原始目标发电功率进行修正以获得修正后的发电机目标发电功率;根据所述修正后的发电机目标发电功率控制所述发电机发电。本发明的方法和车辆,可以提高低温环境下动力电池充电能力。
