摘要:
In a power storage unit in which a bipolar battery is covered with a resin body, at least one through passage is formed to extend through the resin body, and a heat exchange medium is introduced into the through passage so that heat is exchanged between the heat exchange medium and the bipolar battery when the heat exchange medium flows thorough the through passage. The heat exchange medium may be a cooling medium or a heating medium. This configuration promotes heat release from the resin body from which heat cannot be sufficiently released.

摘要:
A battery ECU estimates the SOC by integrating the battery current measured by a current sensor, and the battery voltage Vnis measured by a voltage sensor, and the battery temperature Tnis measured by a thermometer if the fluctuation of the charging/discharging current is great. If the number m of estimations of SOCnis m≦10, m is incremented. The battery internal resistance Rnis estimated from the measured battery temperature Tnby using a correlation map showing the correlation between the previously stored battery temperature T and the battery internal resistance R. An estimation charging/discharging current Inis determined using the measured battery voltage Vn,the battery open voltage Vocvn-1determined on the basis of the previously estimated charged state, and the estimated battery internal resistance Rn. The SOCnis estimated by integrating the estimated charging/discharging current In. If the number m of estimations of the SOCnis m=10, the number m of estimations is changed to 0. The charging/discharging current inis measured by a current sensor. The battery internal resistance Rnis calculated from the battery voltage Vnand the charging/discharging current in. The battery temperature Tnis also measured, and the T-R correlation map is corrected

摘要:
The temperature of a battery in a hybrid car is supervised by temperature sensors. When the temperature of the battery is at a temperature not exceeding a predetermined temperature, a battery ECU issues a command to a control CPU to perform forcible charge/discharge of the battery to raise the temperature of the battery. When raising of the temperature is performed by charging, a requested output from an engine is increased as compared with a usual state. In such a state, motor-generators are operated as generators so as to generate electric power and charge the battery by passing an electric current to the battery rather than generating a driving force. When raising of the temperature is performed by discharging, the requested output from the engine is reduced as compared with the usual state. In this case, the motor-generators are operated as drive motors to consume electric power so as to draw electric current from the battery causing discharge of the battery. The electric current allowed to flow at this time causes internal resistance to be generated in the battery that heats the battery from an inside portion thereof. Thus, an apparatus for controlling a charge/discharge state of a hybrid car can be provided that quickly and easily controls the temperature of the battery to a predetermined temperature.
