The invention provides a bidirectional charging control method and system for an electric vehicle. The method comprises the steps that a user requests to use the electric vehicle for external charging; respectively obtaining the residual electric energy of the electric vehicle and the future travel of the user; predicting an external supply charging limit based on the residual electric energy and the future travel; allowing and prompting a user to use the electric vehicle for external charging; a user uses the electric vehicle for external charging; and when the electric vehicle is about to reach the external supply charging limit, reminding a user of the external supply charging limit. According to the two-way charging control method and system for the electric vehicle, the external supply charging limit is predicted based on the residual electric energy of the electric vehicle and the future travel of the user, whether the electric vehicle is about to reach the external supply charging limit or not is determined, and if yes, the user is reminded of the external supply charging limit; the user does not need to consider whether the residual electric quantity of the electric vehicle can support the own future travel at any time, so that the convenience is improved, the user experience is improved, and meanwhile, the method is more intelligent.

    本发明提供一种电动汽车双向充电控制方法及系统,其中方法包括:用户请求使用电动汽车进行外供充电;分别获取电动汽车的剩余电能以及用户的未来行程;基于剩余电能和未来行程,预测外供充电极限;允许并提示用户使用电动汽车进行外供充电;用户使用电动汽车进行外供充电;当电动汽车即将达到外供充电极限时,对用户进行外供充电极限提醒。本发明的电动汽车双向充电控制方法及系统,基于电动汽车的剩余电能以及用户的未来行程,预测外供充电极限,确定电动汽车是否即将达到外供充电极限,当为是时,对用户进行外供充电极限提醒,无需用户时刻考虑电动汽车的剩余电量能否支撑自己的未来行程,提升了便捷性,提升了用户体验,同时,也更加智能化。
