Energy storage apparatus
An energy storage apparatus includes: an energy storage device group in which a terminal surface and a side surface intersecting the terminal surface are formed by a plurality of arrayed energy storage devices; and a busbar frame holding a plurality of busbars. The busbar frame is provided with a body holding the busbar and disposed on the terminal surface, a connector holder having a connector, to which an external connector is connected, and disposed on the side surface, and a coupling portion coupling the body and the connector holder.
1. An energy storage apparatus comprising:
an energy storage device group in which a plurality of arrayed energy storage devices including terminals form a terminal surface where the terminals are disposed and a side surface intersecting the terminal surface; and
a busbar frame holding a plurality of busbars that connects the terminals adjacent to each other,
wherein
the busbar frame includes:
a body holding the busbars and disposed on the terminal surface;
a connector holder including a connector to which an external connector is connected, the connector holder being disposed on the side surface; and
a coupling portion coupling the body and the connector holder,
wherein the coupling portion couples the connector holder to the body variably between a first posture located along the terminal surface and a second posture located along the side surface,
wherein the connector holder is disposed on the side surface by bending from the first posture to the second posture, and
wherein the energy storage device group further includes an outer case surrounding an outer periphery that includes the side surface and including the terminal surface located at one end, and
the outer case is provided with a locking portion that locks the connector holder in the second posture.
2. The energy storage apparatus according to claim 1 , wherein the coupling portion is formed integrally with the body and the connector holder and is bendable with respect to the body and the connector holder.
3. The energy storage apparatus according to claim 1 , wherein a binding portion surrounding a plurality of wires connected to the connector is formed at an end portion of the connector holder located on the body side.
4. The energy storage apparatus according to claim 1 , wherein in the connector holder, a void in which the wires are installed is formed around the connector.
5. The energy storage apparatus according to claim 1 , wherein
the connector holder includes:
a binding portion that is provided at an end portion located on the body side and surrounds a plurality of wires connected to the connector; and
a void that is provided around the connector and in which the wires are installed, and
at least one surface of an outer wall constituting the binding portion or the void is made of an openable and closable cover.
6. The energy storage apparatus according to claim 1 , wherein a direction in which the external connector is connected to the connector is located parallel to the side surface.
7. The energy storage apparatus according to claim 1 , wherein the connector includes a first connector and a second connector juxtaposed against each other.
