Abstract

A power storage device includes a battery containing body, an electronic device unit, and a chassis for housing them, wherein at a side surface portion of the chassis, an opening for inserting and removing the battery containing body and the electronic device unit is provided; an openable and closable pivoting member is provided inside the opening, the pivoting member, when closed, preventing removal of the battery containing body, and when opened, preventing insertion of the electronic device unit as removed; and the electronic device unit is housed and disposed adjacent to the battery containing body, and includes an opening prevention guide capable of engaging with the pivoting member and thereby preventing the pivoting member from being opened when the electronic device unit is housed.

First claim

The invention claimed is:

1. A power storage device comprising a battery containing body, an electronic device unit, and a chassis for housing the battery containing body and the electronic device unit,
wherein at a side surface portion of the chassis, an opening for inserting and removing the battery containing body and the electronic device unit via the side surface portion is provided;
an openable and closable pivoting member is provided inside the opening, the pivoting member, when closed, preventing removal of the battery containing body, and when opened, preventing insertion of the electronic device unit as removed; and
the electronic device unit is housed and disposed adjacent to the battery containing body, and includes an opening prevention guide capable of engaging with the pivoting member and thereby preventing the pivoting member from being opened when the electronic device unit is housed.

2. The power storage device according to claim 1 , wherein in a state in which the electronic device unit is housed, the opening prevention guide is in contact with a surface of the pivoting member when the pivoting member is closed or pivots.

3. The power storage device according to claim 1 or 2 , wherein the pivoting member, when opened, pivots toward a housing section for the electronic device unit and is thereby positioned so as to interrupt a path for insertion of the electronic device unit.

4. The power storage device according to claim 1 , wherein the pivoting member, when closed, covers at least a part of an end portion of the battery containing body, the end portion facing the opening, thereby preventing the battery containing body from being removed.

5. The power storage device according to claim 1 , wherein the pivoting member is provided with a holding hole for holding a cable connector for connection to the electronic device unit when the cable connector is not connected.

6. The power storage device according to claim 1 , wherein more than one said battery containing body is included, and the respective battery containing bodies have a flat shape and are arranged upright in parallel such that end portions of the battery containing bodies face the opening; and
the electronic device unit is disposed adjacent to a battery containing body at an end of the arrangement of the battery containing bodies.

7. The power storage device according to claim 6 , wherein the electronic device unit has a flat shape, and is placed upright such that an end portion of the electronic device unit faces the opening.

8. The power storage device according to claim 6 , wherein the chassis includes a first housing section on a lower-tier side and a second housing section on an upper-tier side, and the battery containing bodies are arranged in parallel in each of the first and second housing sections.

9. The power storage device according to claim 1 , wherein the chassis includes a cover body that can open and close the opening.

10. The power storage device according to claim 1 , wherein the electronic device unit is a battery management unit.

11. The power storage device according to claim 1 , further comprising a power conditioner.

12. The power storage device according to claim 11 , wherein the chassis has a cuboidal shape including a first side surface portion including the opening, and a second side surface portion facing the first side surface portion; and
the power conditioner is installed on an inner wall surface of the second side surface portion.

13. The power storage device according to claim 1 , wherein the battery containing body holds a film package battery.

14. The power storage device according to claim 1 , wherein the battery containing body holds a lithium ion secondary battery.

15. The power storage device according to claim 1 , wherein the battery containing body is a battery module.

16. A power storage system comprising a power storage device according to claim 1 , and a control system unit for controlling the power storage device.
