Abstract
【解決手段】本発明は、走行用モータに電力を供給するバッテリに外部充電可能な車両の蓄電システムである。蓄電システムは、バッテリの温度を検出する温度センサと、バッテリを昇温させるバッテリヒータと、外部電源に接続され、外部電力をバッテリ及びバッテリヒータそれぞれに出力する充電器と、バッテリの温度が所定温度以下のときに、外部電力をバッテリに充電させる充電制御と、外部電力の一部をバッテリヒータに供給してバッテリを昇温させる温度調節制御と、を行うコントローラと、を備える。コントローラは、バッテリのSOCが所定値よりも大きい領域においては、バッテリの温度が所定温度以下のときにバッテリヒータに供給される電力が、バッテリのSOCが所定値以下である領域においてバッテリヒータに供給される電力よりも小さくなるように制御する。
