摘要： A method for charging a battery pack including a plurality of battery units includes: a first step of charging the battery units with a first electric current at a first rate until an internal pressure of at least one of the plurality of battery units begins to increase; and a second step of charging/discharging the battery units with a second electric current which is lower than the first electric current at a second rate which is lower than the first rate after the internal pressure of the at least one of the plurality of battery units has begun to increase.

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.

摘要翻译： 混合动力汽车中的电池的温度由温度传感器监控。 当电池的温度处于不超过预定温度的温度时，电池ECU向控制CPU发出命令以执行电池的强制充电/放电以提高电池的温度。 当通过充电进行温度升高时，与通常状态相比，发动机的要求输出增加。 在这样的状态下，电动发电机作为发电机进行动作，以产生电力，并通过使电流通过电池对电池进行充电，而不是产生驱动力。 当通过放电进行温度升高时，与通常状态相比，要求的发动机输出减少。 在这种情况下，电动发电机作为驱动电动机操作以消耗电力，以便从电池中吸取电流引起电池的放电。 此时允许流过的电流在电池中产生内部电阻，从而从其内部加热电池。 因此，可以提供用于控制混合动力汽车的充放电状态的装置，其能够快速且容易地将电池的温度控制在预定温度。

摘要： The charge and discharge are performed by a proper electric power corresponding to the service environment of a battery and the state of the battery. When the temperature of the battery is not more than a specified temperature, or not less than another specified temperature, the upper limit value Pin-s of the charging electric power and the upper limit value Pout-s of the discharging electric power are determined so as to be smaller than those at a normal temperature. The temperature of the battery is detected, and the charging electric power and the discharging electric power are determined so that they may be not more than the upper limit values Pin-s, Pout-s of the charging and the discharging electric power at this temperature, and the charge control of the battery is performed.
