摘要： In the area of the charge level of 20.about.80% where the charge level of a battery does not appear in the terminal voltage of the battery, the battery ECU estimates charge level by integrating the currents of the charge and discharge of the battery. When the engine ECU detects that the ignition key is turned on, the motor generators are driven by the engine, and the generated electric power is accumulated in the battery. When the area where the charge level appears in the terminal voltage, is reached, the calculation of the charge level is performed from the current and voltage at that time. When this charge level has reached 80%, the calibration of said estimated charge level is performed by this value. Furthermore, it is also possible for this calibration to be prohibited when a heavy current is flowing and the error may become large in the calculation of the charge level. By the above mentioned methods, the charge level of a battery can accurately be detected.

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： A voltage detector (12) detects the voltage levels of the battery blocks of the battery set (10). A presence of an overdischarged cell is detected when a voltage difference between each of the battery blocks reaches or exceeds a predetermined value (for example, 1V). At this point, a battery ECU (14) sets the SOC value of the battery set (10) at the lower control limit value (for example, 20%). This triggers an HV ECU (16) to control the load (18) such that charging is effectuated in the battery set (10). If further discharge occurs, the battery set (10) is disconnected from the load (18) by a relay (20).

摘要： In a pre-replacement process, a replacement battery module is provided with a memory effect before being dispatched, by performing at least one of the process of performing a cyclic charge/discharge operation on the replacement battery module while limiting the width of SOC change to an intermediate range, and the process of setting an initial SOC and then letting the replacement battery module stand for a predetermined time in an environment of temperature above normal temperature. This pre-replacement process substantially eliminates the difference between the voltage characteristic of the replacement battery module yet to be used and the voltage characteristic of a battery module having a history of use, thereby achieving a uniform voltage characteristic of a battery pack as a whole.

摘要： A hydrogen sensor which may be employed in an overcharge/overdischarge detector for a battery and a hydrogen leakage detector for a fuel cell is provided. The hydrogen sensor includes a sensor element and a diffused resistor member. The gas to be measured passes through the diffused resistor member and reaches the sensor element. The sensor element outputs a signal indicative of the concentration of hydrogen contained in the gas as a function of a decrease in concentration of oxygen contained in the gas arising from reaction of the hydrogen on the oxygen. The diffused resistor member is so designed that speeds of diffusion of the hydrogen and the oxygen when passing through the diffused resistor member are different from each other for increasing the sensitivity of measurement of the concentration of hydrogen.

Thereby, the internal resistance per cell is reduced, and higher power output and improved service life characteristics are achieved.
