The invention provides an automobile in-transit battery heating control method and device and an electric automobile. The method comprises the steps that current battery information and navigation information of the automobile are obtained; whether the battery is in a low-temperature environment or not is judged according to the battery information, if yes, the first residual capacity proportion and the second residual capacity proportion of the battery reaching the destination are calculated according to the navigation information and the battery information, and the first residual capacity proportion is the residual capacity proportion of the battery without heating starting; the second residual electric quantity is the residual capacity proportion of the battery for starting heating; and judging whether the first residual capacity proportion is lower than the second residual capacity proportion or not, and if yes, sending a thermal control instruction. According to the invention, whether the heating saving capacity is started or not is judged according to the first residual capacity ratio and the second residual capacity ratio, so that intelligent heating control is provided for a user, the vehicle use cost of the user is saved, and the vehicle use experience is improved.

    本发明提供了一种汽车在途电池加热控制方法、装置及电动汽车,其中方法包括:获取汽车当前的电池信息和导航信息;根据电池信息判断电池是否处于低温环境,如果是,根据导航信息和电池信息计算到达目的地的第一剩余容量占比和第二剩余容量占比,其中第一剩余容量占比为未开启加热的电池剩余容量占比,第二剩余电量为开启加热的电池剩余容量占比;判断第一剩余容量占比是否低于第二剩余容量占比,如果是,则发送热控制指令。本发明根据第一剩余容量占比和第二剩余容量占比判断开启加热节约容量或者是不开启加热节约容量,从而为用户提供智能加热的控制,节约用户用车成本,提升用车体验。
