摘要： The temperature of a battery (50) is supervised by temperature sensor (74). When the temperature of the battery is not higher than a predetermined temperature, a battery ECU (68) issues a command to a control CPU (56) to perform forcible charge/discharge of the battery (50) to raise the temperature of the battery. When raising of the temperature is performed by charging, a requested output from the engine (10) is enlarged as compared with a usual state. Thus, motor-generators (26, 28) are operated as generators so as to generate electric power. Thus, electric power is charged to the battery so as to pass an electric current. When raising of the temperature is performed by discharging, the requested output from the engine (10) is reduced as compared with the usual state. Thus, the motors/generator (28) is operated as a motor to consume electric power so as to pass an electric current. The electric current allowed to flow at this time causes internal resistance to be generated in the battery so as to heat the battery from the inside portion thereof. Thus, an apparatus for controlling a charge/discharge state of a hybrid car structured to be capable of quickly and easily controlling the temperature of the battery to a predetermined temperature can be provided.

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.

摘要： The present invention provides a method of replacing secondary batteries. In the method, batteries can be replaced at a low cost and performance of an overall battery assembly can be maximized after the battery replacement. The battery assembly is composed by electrically connecting a plurality of secondary batteries in series or in parallel. When a portion of the secondary batteries is judged as defective, the defective batteries are replaced by replacement batteries. In an aspect of the method, voltage is detected for every predetermined voltage detection block unit concerning secondary batteries composing the battery assembly in order to judge defects of the secondary batteries in the voltage detection block unit. Batteries in a voltage detection block unit will be replaced with replacement batteries if they are judged as defective.

摘要： In the area of the charge level of 20 ∼ 80% where the charge level of a battery (50) does not appear in the terminal voltage of the battery, the battery ECU (68) estimates charge level by integrating the currents of the charge and discharge of the battery. When the engine ECU (46) detects that the ignition key is turned on, the motor generators (26, 28) are driven by the engine (10), and the generated electric power is accumulated in the battery (50). 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： 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).
