Figure 5 shows the relationship between storage battery temperature and battery capacity, and as is clear from Figure 5, the battery temperature is 40°C.
When the temperature peaks at , the battery capacity decreases rapidly as the temperature rises above that point. In the case of the single-crystal battery 1 using the hydrogen storage alloy used here, the battery temperature becomes about 40°C at the end of charging at a room temperature of 25°C. Therefore, among the single crystal batteries arranged side by side as shown in Fig. 4, the temperature of the outermost single crystal battery 1-2.

Battery l: The battery capacity itself is set high to compensate. Specifically, the battery capacity of the inner single crystal battery 1=1... is set to be 10 to 25% higher than that of the outermost single crystal battery 1-2.1-2. By adopting such a configuration, even when a plurality of single crystal batteries 1 are closely arranged in a system, it is possible to compensate for the temperature increase and keep the total energy output constant.
