PROBLEM TO BE SOLVED: To provide a temperature raising system of a battery which allows for execution of normality determination processing, even if a low temperature environment is not brought about after replacing a heater or a temperature raising relay.SOLUTION: A temperature raising system includes a drive battery 13 for supplying power to a traveling motor of a vehicle, a heater for raising the temperature of the drive battery, a temperature raising relay 15 for connecting or disconnecting the power path of the battery for auxiliary machine and the heater, and a control section for controlling the temperature raising relay. The control section performs charging time temperature rise control for turning the temperature raising relay ON from OFF, while charging the drive battery from external power supply and the battery temperature of the drive battery is equal to or lower than a first threshold temperature, performs normality determination processing by turning the temperature raising relay ON, when the battery temperature is equal to or lower than a second threshold temperature higher than the first threshold temperature, after replacement of the heater or the temperature raising relay, and does not perform normality determination processing by turning the temperature raising relay OFF, when the battery temperature exceeds the second threshold temperature.SELECTED DRAWING: Figure 1
【課題】ヒータまたは昇温リレーの交換後に、低温環境でない場合でも、正常判定処理の実行を可能とするバッテリの昇温システムを提供することである。【解決手段】昇温システムは、車両の走行用モータに電力を供給する駆動用バッテリ13と、駆動用バッテリを昇温するヒータと、補機用バッテリとヒータとの電力経路を接続または切断する昇温リレー15と、昇温リレーを制御する制御部とを含む。制御部は、外部電源から駆動用バッテリへの充電中であって、駆動用バッテリの電池温度が第1閾値温度以下である場合に昇温リレーをオフからオンに切り替える充電時昇温制御を行い、ヒータまたは昇温リレーの交換後であって、電池温度が第1閾値温度より高い第2閾値温度以下である場合に昇温リレーをオンし正常判定処理を行い、電池温度が第2閾値温度を超える場合には昇温リレーをオフして正常判定処理を行わない。【選択図】図1
