First, the configuration will be described. In FIG. 1, reference numeral 1 denotes an assembled battery in which a plurality of unit cells are connected in series or in parallel, and is charged by a charger 2. The assembled battery 1 is DC
A current is made to flow through the heater 3 via the / DC converter 4. Further, it is connected via a switch 6 to a regenerative resistor 5 that can consume a large current.

であるので、回生抵抗５による放電を構成している。FIG. 2 is a diagram showing a control flowchart under the configuration of FIG. Next, the operation will be described. Charging of the assembled battery 1 is started by the charger 2. When overcharge is detected by the voltage sensor 9, a signal is transmitted to the charger 2 via the controller 7 and charging is stopped. When charging is completed, the battery temperature T detected by the temperature sensor 8 attached to the assembled battery 1
b is compared with the set temperature T1, and if the battery temperature Tb is equal to or higher than the set temperature T1, the charging ends. On the other hand, if the temperature T1 is equal to or lower than the temperature set value T1, the switch 6 of the regenerative resistor 5 is turned on by the signal from the controller 7 to operate the heater 3 to start the discharge. The temperature of the assembled battery 1 rises due to the heating by the heater 3 and the internal resistance heat generation of the battery. The heat generated by the internal resistance needs to consume about 100 w of electric power per unit cell, and the electric power required by the heater 3 is about 10 w. Therefore, the regenerative resistance 5 constitutes discharge.

を見込んでいるためである。During discharge, the temperature of the battery is constantly monitored, and when the temperature Tb is equal to or higher than the temperature set value T2 or is overdischarged , the discharge is stopped. When the temperature Tb becomes equal to or higher than the temperature set value T2, the charging is started again and is performed until the overcharge is detected. When overcharge is detected, the process proceeds to the next charging step. The temperature set value T2 is set higher than the temperature set value T1. The reason for doing this is that the temperature drop during charging is expected.

図っている。With the above structure, the temperature of the battery is maintained at the temperature setting T1 or higher at the end of charging, so that the charging capacity can be increased and the charging time can be shortened. As shown in FIG. 3, since the internal resistance of the battery is large at low temperatures, if the battery is charged without being warmed, the charging capacity will be small in constant current charging (FIG. 5).
There is a problem in that constant voltage charging takes time (FIG. 4). Further, there are problems that heating by the heater 3 takes too much time and the battery cannot be heated uniformly. Therefore, taking into consideration that the battery can be uniformly heated and that it can be heated in a short time, the heat generated by the internal resistance is taken into the configuration, and the heater 3 is not caused by the heating of the battery but by the internal resistance. By incorporating the heat generation into the configuration as a means for preventing the heat generation from being radiated to the outside, the charge capacity is increased and the charge time is shortened.

きる。In this case, the unit cells 1a at both ends of the module battery 1b have a larger heat radiation area than the other unit cells 1a.
It has a distribution as shown in. There is a problem that the charging capacity does not increase because the single cells 1a at both ends having a low temperature and a large internal resistance determine the charging capacity. Therefore, it is possible to increase the charging capacity by preventing the internal heat generation of the unit cells 1a at both ends from being dissipated by the heaters 3 and 3.

As shown in FIG. 8, the module battery 1b is contained in the battery case 11. The fan 9 and the heater 3 are attached to the circulation flow path 10 to heat the air in the battery case 11. With this configuration, it is possible to increase the charging capacity and shorten the charging time.

If the heater 3 is attached as described above, there is an increase in weight due to an increase in wiring and an increase in cost, which is not practical. Therefore, with this structure, the structure can be realized easily and at low cost.
