Energy storage apparatus for suppressing adverse effects exerted on circuit boards

An energy storage apparatus comprising:

• an energy storage device;
• an outer case comprising a second restricting portion and a wall surface;
• a first circuit board which is connected to the energy storage device and through which a first current flows;
• a second circuit board through which a second current larger than the first current flows;
• and
• a holding member which holds the energy storage device,
• wherein:
• the second circuit board is disposed such that the second circuit board opposedly faces a position which differs from a long side surface of a container of the energy storage device;
• the second restricting portion restricts a movement of the holding member in a direction along the wall surface of the outer case;
• the holding member is smaller than the outer case and is disposed in an offset manner with respect to the outer case;
• an L-shaped space is formed between the holding member and the outer case;
• and
• the second restricting portion restricts the movement of the holding member by engaging with a portion of the holding member.

An energy storage apparatus comprising:

• an energy storage device including a container;
• an outer case;
• a first circuit board which is connected to the energy storage device and through which a first current flows;
• and
• a second circuit board through which a second current larger than the first current flows,
• wherein:
• the container comprises:
• a lid portion on which a terminal is disposed;
• a bottom portion opposed to the lid portion;
• a short side surface;
• and
• a long side surface;
• the short side surface and the long side surface connect the bottom portion;
• and
• the second circuit board is disposed such that the second circuit board opposedly faces a position which differs from the long side surface of the container of the energy storage device.

• the outer case includes, on an inner surface of a bottom wall thereof, a first restricting portion which restricts a movement of at least one circuit board out of the first circuit board and the second circuit board in a direction along the bottom wall,
• the first restricting portion includes a recessed portion into which at least one circuit board out of the first circuit board, and
• the second circuit board is detachably inserted in a direction toward the bottom wall.
