A battery temperature control device for an electric vehicle is provided which is capable of maintaining both the range of the electric vehicle and the battery life at a high level without drastically reducing either of them. A recommended temperature range suitable for battery use and a usable temperature range in which a battery is usable and which is wider than the recommended temperature range are included, and while the battery temperature is basically controlled to converge to the recommended temperature range to maintain the battery life, in a situation where the power consumption necessary for controlling the battery temperature to converge to the recommended temperature is increased, making it difficult to travel a desired travelling distance, the recommended temperature range is switched to the usable temperature range and the battery temperature is controlled to converge to the usable temperature range, and the power consumption necessary for controlling the battery temperature is suppressed and the range of the vehicle is maintained. |
