JP 2009-170687 A

  In the conventional electrochemical storage element module, each capacitor and each heat transfer pressure rubber are arranged without gaps, so the flow of cooling air sent into the metal casing by the cooling fan is the cell and heat transfer pressure rubber. This makes it easier for dust and dirt to accumulate in the metal casing. Thereby, it becomes easy to produce a short circuit between the positive electrode and negative electrode of a cell, and an electrochemical electrical storage element module will become easy to fail. In addition, the cooling fan needs to be maintained, and the maintenance and inspection work of the electrochemical storage element module takes time.

  The present invention has been made to solve the above-described problems, and an object of the present invention is to obtain an elevator battery module that can facilitate maintenance and inspection work and can be made less likely to fail.

There are provided an opening and an exhaust port disposed at a position higher than the intake port.

  In the battery module of the elevator according to the present invention, a ventilation path is formed between the cells by interposing a spacer between at least one of the cells, and the container is arranged in accordance with the position of the ventilation path in the cell arrangement direction. Since the intake port and the exhaust port arranged at a position higher than the intake port are provided, the resistance to the cooling air flowing from below to above in the container can be reduced. Therefore, the ascending airflow generated by the heat generation of each cell can facilitate the flow of the cooling air into the container, and can facilitate the outflow of the cooling air within the container. Thereby, the stay of the cooling air in the container can be reduced, and the failure of the battery module can be made difficult to occur. In addition, a sufficient cooling effect can be obtained by the cooling air generated by the rising air flow in the container, so that it is not necessary to attach a cooling fan that requires maintenance to the container, and the maintenance and inspection work of the battery module can be facilitated. it can.
