The invention relates to a charging control method and system for an extended-range electric vehicle and a computer readable medium, and the charging control method comprises the steps: obtaining navigation information which comprises a destination for charging the electric vehicle and the remaining mileage of current navigation to the destination; calculating the travelable mileage of the current remaining electric quantity; judging whether the travelable mileage of the current remaining electric quantity is greater than or equal to the current remaining mileage for navigating to the destination, if so, controlling the range extender not to generate electricity, and if not, calculating the generated power of the range extender; calculating the endurance mileage of the range extender according to the generated power of the range extender; and if the sum of the endurance mileage of the range extender and the travelable mileage of the current remaining electric quantity is greater than or equal to the current remaining mileage for navigating to the destination, controlling the range extender to generate power according to the generated power of the range extender. The starting and stopping time of the range extender can be automatically calculated according to the driving destination, it can be guaranteed that the vehicle can reach the destination, the range extender is not started as far as possible for power generation, and the vehicle using cost is reduced.

    本发明涉及一种增程式电动车的充电控制方法、系统及计算机可读介质,该充电控制方法包括:获取导航信息,导航信息包括可供电动车充电的目的地以及当前导航至目的地的剩余里程;计算当前剩余电量的可行驶里程;判断当前剩余电量的可行驶里程是否大于等于当前导航至目的地的剩余里程,若是,则控制增程器不发电,若否,则计算增程器的发电功率;根据增程器的发电功率计算增程器续航里程;若增程器续航里程与当前剩余电量的可行驶里程之和大于等于当前导航至目的地的剩余里程,则根据增程器的发电功率控制增程器发电。本发明可以根据驾驶目的地自动计算增程器的启停时间,可以保证车辆能够到达目的地且尽可能不启动增程器发电,降低了用车成本。
