<p>PROBLEM TO BE SOLVED: To provide a battery unit capable of simplifying connection parts and connection paths and reducing connection electric resistance.SOLUTION: A battery unit comprises a plurality of battery blocks, a housing for accommodating the plurality of battery blocks and connection metal plates for electrically connecting adjacent ones of the battery blocks. Each of the battery blocks comprises a plurality of batteries with respective positive and negative electrode terminal parts being aligned in the same direction, a stationary portion for fixing each of the positive and negative electrode terminal parts of the plurality of batteries, a positive electrode plate connected via the stationary portion to the positive electrode terminal parts of the plurality of batteries, and a negative electrode plate connected via the stationary portion to the negative electrode terminal parts of the plurality of batteries. The positive electrode plate and negative electrode plate have a terminal connection part disposed on the positive electrode terminal parts or negative electrode terminal parts of the plurality of batteries and an extraction part disposed on the side face of each of the battery blocks. The extraction parts of the adjacent battery blocks are mutually electrically connected by the connection metal plate.</p> |
