Abstract

An onboard battery includes predetermined members such as battery modules, and a housing case. An internal space of the housing case is partitioned by a partition plate into an upper space and a lower space in which the predetermined members are disposed, and the battery modules are disposed below the partition plate. The housing case has a bottom surface on which the battery modules are disposed, a front surface that has a front-side tightening part, and a rear surface that has a rear-side tightening part. The partition plate has a partition base that partitions the internal space of the housing case into the upper space and the lower space, a front-side fixation target part that is continuous with a front end of the partition base, and a rear-side fixation target part that is continuous with a rear end of the partition base.

First claim

1 . An onboard battery comprising:
predetermined members comprising at least one battery module; a housing case an internal space of which is partitioned by a partition plate into an upper space and a lower space in which the predetermined members are disposed, and the at least one battery module is disposed below the partition plate, wherein the housing case has a bottom surface on which the at least one battery module is disposed, a front surface that has a front-side tightening part, and a rear surface that has a rear-side tightening part, the partition plate has a partition base that partitions the internal space of the housing case into the upper space and the lower space, a front-side fixation target part that is continuous with a front end of the partition base, and a rear-side fixation target part that is continuous with a rear end of the partition base, the front-side fixation target part of the partition plate is fixed to the front-side tightening part, and the rear-side fixation target part of the partition plate is fixed to the rear-side tightening part, the bottom surface is made stronger than the rear surface, and the rear-side fixation target part is made stronger than the partition base.

2 . The onboard battery according to claim 1 , wherein
the partition base has a bent part between the front-side fixation target part and the rear-side fixation target part, the bent part being bent to protrude upward.

3 . The onboard battery according to claim 2 , wherein
a part of the partition base in front of the bent part serves as a front-side surface, and a part of the partition base behind the bent part serves as a rear-side surface, and the front-side surface is located at a higher position than a position of the rear-side surface.

4 . The onboard battery according to claim 1 , wherein
a first high-voltage device and a second high-voltage device are attached to the partition plate, the first high-voltage device and the second high-voltage device being located apart from each other in a longitudinal direction, and a bent part is located between the first high-voltage device and the second high-voltage device.

5 . The onboard battery according to claim 2 , wherein
a first high-voltage device and a second high-voltage device are attached to the partition plate, the first high-voltage device and the second high-voltage device being located apart from each other in a longitudinal direction, and the bent part is located between the first high-voltage device and the second high-voltage device.

6 . The onboard battery according to claim 1 , wherein
a bent part is located from a left end to a right end of the partition plate.

7 . The onboard battery according to claim 2 , wherein
the bent part is located from a left end to a right end of the partition plate.

8 . An onboard battery comprising:
predetermined members comprising at least one battery module; a housing case an internal space of which is partitioned by a partition plate into an upper space and a lower space in which the predetermined members are disposed, and the at least one battery module is disposed below the partition plate, wherein the housing case has a bottom surface on which the at least one battery module is disposed, a front surface that has a front-side tightening part, and a rear surface that has a rear-side tightening part, the partition plate has a partition base that partitions the internal space of the housing case into the upper space and the lower space, a front-side fixation target part that is continuous with a front end of the partition base, and a rear-side fixation target part that is continuous with a rear end of the partition base, the front-side fixation target part of the partition plate is fixed to the front-side tightening part, and the rear-side fixation target part of the partition plate is fixed to the rear-side tightening part, and the partition plate has a bent part between the front-side fixation target part and the rear-side fixation target part, the bent part being bent to protrude upward.

9 . The onboard battery according to claim 8 , wherein
a part of the partition plate in front of the bent part serves as a front-side surface, and a part of the partition base behind the bent part serves as a rear-side surface, and the front-side surface and the rear-side surface are located in a horizontal state.

10 . The onboard battery according to claim 9 , wherein
the front-side surface is located at a higher position than a position of the rear-side surface.

11 . The onboard battery according to claim 8 , wherein
a first high-voltage device and a second high-voltage device are attached to the partition plate, the first high-voltage device and the second high-voltage device being located apart from each other in a longitudinal direction, and the bent part is located between the first high-voltage device and the second high-voltage device.

12 . The onboard battery according to claim 9 , wherein
a first high-voltage device and a second high-voltage device are attached to the partition plate, the first high-voltage device and the second high-voltage device being located apart from each other in a longitudinal direction, and the bent part is located between the first high-voltage device and the second high-voltage device.

13 . The onboard battery according to claim 8 , wherein
the bent part is located from a left end to a right end of the partition plate.

14 . The onboard battery according to claim 9 , wherein
the bent part is located from a left end to a right end of the partition plate.
