Abstract
An energy storage apparatus includes: a plurality of energy storage devices arranged in a row in a first direction; and a plurality of spacers which are arranged adjacently to the energy storage devices in the first direction. Each of the spacers includes a passage defining portion which defines, with the energy storage device arranged adjacently to the spacer in the first direction, passages. The energy storage devices arranged at both ends in the first direction are cooled more easily than the energy storage devices arranged between the energy storage devices arranged at both ends in the first direction.
Claims19
An energy storage apparatus comprising:
- a plurality of energy storage devices arranged in a first direction, the energy storage devices including two end energy storage devices and energy storage devices arranged between the two end energy storage devices;
- an inner spacer arranged between the energy storage devices;
- and
- an outer spacer arranged at an end of the energy storage devices,
- wherein the inner spacer defines an inner passage with the energy storage device adjacently arranged to the inner spacer on one side in the first direction,
- wherein the outer spacer defines an outer passage with an end energy storage device of the two end energy storage devices,
- wherein a relation qo/qi>1 is satisfied, where qo is a mean value of heat transfer amounts transferred from the end energy storage devices to a fluid passing the inner and outer passages of the two end energy storage devices, qi is a mean value of heat transfer amounts transferred from the energy storage devices arranged between the two end energy storage devices to a fluid passing the inner passages,
- wherein the inner spacer includes:
- a first abutting portion which is formed along and in contact with the energy storage device arranged adjacently to the inner spacer on one side in the first direction;
- and
- a second abutting portion which is formed along and in contact with the energy storage device arranged adjacently to the inner spacer on an other side in the first direction, and
- wherein the first and the second abutting portions do not overlap with each other as viewed in a second direction perpendicular to the first direction.
