PROBLEM TO BE SOLVED: To prevent lowering of charging rate during external charging under low temperature environment.SOLUTION: A secondary battery warming device of vehicle includes a secondary battery (lithium ion battery 3), charging control means (controller 7), and temperature rising means (temperature rising device 6). The temperature rising means has a latent heat storage material 62, and an electric heater 63 configured to warm the latent heat storage material. When the temperature of the secondary battery is lower than a predetermined temperature zone, the charging control means increases temperature of the secondary battery through the latent heat storage material, by supplying power of an external power supply to the electric heater, stops power supply to the electric heater after temperature of the secondary battery exceeds the predetermined temperature zone, and starts external charging of the secondary battery by supplying the power of the external power supply to the secondary battery.SELECTED DRAWING: Figure 1

    【課題】低温環境下の外部充電時に充電レートが低下することを防止する。【解決手段】車両の二次電池加温装置は、二次電池(リチウムイオン電池3)と、充電制御手段(コントローラ7)と、昇温手段(昇温デバイス6)と、を備える。昇温手段は、潜熱蓄熱材62と、潜熱蓄熱材を加温するよう構成された電気ヒーター63と、を有する。充電制御手段は、二次電池の温度が、所定の温度帯よりも低いときには、外部電源の電力を電気ヒーターに供給することによって、潜熱蓄熱材を通じて二次電池の温度を高めると共に、二次電池の温度が所定の温度帯以上になった後、電気ヒーターへの電力の供給を停止しかつ、外部電源の電力を二次電池に供給することによって二次電池の外部充電を開始する。【選択図】図1
