の原因となっていた。However, in the conventional device, the substantial support portion of each battery module is
Since it is at both ends, the amplitude of each battery module becomes large due to vibration, and there is a risk of breaking the connection between the positive and negative electrodes of adjacent batteries. In addition, since the bus bar is embedded in the end plate and is immovable, it is difficult to deal with variations in the axial dimension of the battery module. In addition, synthetic resin boxes are not suitable for comparison. Since it is relatively large and requires considerable dimensional accuracy, the cost of the molding die is very high, leading to an increase in the cost of the power supply device and a weight increase.
