The invention provides an in-vehicle battery system. In an in-vehicle battery system, a battery is prevented from exceeding a use upper limit temperature. When the battery temperature (T) is high, the output power (Wout) of the battery is limited, and the temperature rise is suppressed. When the outside air temperature is equal to or greater than a predetermined temperature, the traveling load of the vehicle is equal to or greater than a predetermined traveling load, and the operating load of the battery cooling device is equal to or greater than a predetermined operating load, the temperature of the battery cooling device is within a temperature range equal to or greater than a second power limit lower limit temperature (Tr2) that is equal to or less than a first power limit lower limit temperature (Tr1) during normal operation. The output power of the battery is limited using a high-load output limit value (Wrh) that is lower than the normal output limit value (Wrn).

    本发明提供一种车载电池系统。在车载电池系统中,避免电池超过使用上限温度。在电池温度(T)为高温时,限制电池的输出电力(Wout),抑制温度上升。在满足外部气体温度为预定温度以上、车辆的行驶负荷为预定行驶负荷以上、电池冷却装置的运转负荷为预定运转负荷以上这三个条件时,在通常时的第一电力限制下限温度(Tr1)以下的第二电力限制下限温度(Tr2)以上的温度范围内,使用比通常时输出限制值(Wrn)低的高负荷时输出限制值(Wrh)来限制电池的输出电力。
