て特性に悪影響を及ぼすという問題があつた。At the time of starting the battery (1), when the temperature is raised from the heat retention temperature to about 120 to 130 ° C, which can be raised by the heat of reaction of the battery, the cooling medium is heated by the heat exchanger (3) or the heater as shown in Fig. 4. Then, the temperature is raised by circulatingly supplying the heating medium to the battery. However, at the start of startup, the medium temperature in the circulation path is room temperature, and even if the medium is heated by the heat exchanger or the heater, the heat is absorbed in the circulation pipeline, so the heating medium temperature at the battery inlet is higher than the battery temperature in the initial stage of temperature increase. Low. Therefore, conversely, the heat of the battery is taken away by the medium, and the battery temperature becomes lower than the heat retention temperature, which causes a problem that the phosphoric acid electrolyte in the matrix deteriorates and adversely affects the characteristics.
