Patent attributes
An onboard battery includes a battery module; and high-voltage devices. An inside of a housing case is partitioned into respective predetermined parts by a partition plate in the onboard battery. The partition plate has a disposition hole. The onboard battery includes, as the high-voltage devices, a first high-voltage device disposed on the partition plate and a second high-voltage device configured to be cooled by a convection caused by a cooling fan and attached to the partition plate with a part of the second high-voltage device protruding downward from the disposition hole. The partition plate has a discharge hole for a heat emitted from the first high-voltage device. The discharge hole communicates with a heat exhaust path for a heat emitted from the second high-voltage device.
