    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 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： 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).
