A protection structure for an on-board battery. The on-board battery includes a battery stack and is configured to be mounted on a vehicle. The protection structure includes a first frame, a second frame, and a fixing member. The first frame is to be coupled to an upper portion of a battery case that contains the battery stack, so as to fix the battery case to a vehicle body of the vehicle. The second frame is to be disposed above the battery case and to be coupled to the first frame. The fixing member is to be fixed to the second frame so as to suspend and support the battery stack. The second frame is to be disposed in a direction crossing a longer direction of the battery stack and at least at an approximate center in the longer direction of the battery stack.

Protection structure for on-board battery

A vehicle battery protection structure includes a vehicle frame member, a first duct, and a second duct. The vehicle frame member is disposed in a region including a battery. The vehicle frame member has a through hole. The battery is mountable on a vehicle. The first duct is disposed on an outside of the battery at a location oriented toward an outside of the vehicle. The second duct is inserted through the through hole of the vehicle frame member. The second duct is disposed to overlap the first duct in a vertical direction of the first duct on the outside of the battery at the location oriented toward the outside of the vehicle.

Vehicle battery protection structure

A battery stack structure includes a battery stack, a passage, a junction box, and a bus bar. The battery stack includes spaced battery cells. The passage is adjacent to a first side of the battery stack. The passage allows air to flow in the passage before the air cools the battery stack. The junction box is adjacent to a second side of the battery stack. The junction box allows the air to flow in the junction box after the air has cooled the battery stack. The junction box contains an electronic device. The bus bar is contained in the junction box and is electrically and thermally coupled to the electronic device. The bus bar allows passing of current. The direction of the flow of the air flowing from the battery stack faces a major surface of the bus bar.

Battery stack structure

A vehicle battery temperature control apparatus includes a battery temperature detector, first and second ducts, an exhaust pipe, a heat receiver, a blower fan, and a processor. The processor causes the blower fan to rotate in one of opposite directions, thereby introducing cooling air from the first duct into a battery compartment, and emitting the cooling air that has cooled a battery to the outside via the second duct, if the battery temperature is higher than a first set temperature, and causes the blower fan to rotate in the other direction, thereby introducing air raised in temperature by exchanging heat with the exhaust pipe through the heat receiver from the second duct into the battery compartment, and emitting the air that has raised the temperature of the battery to the outside via the first duct, if the battery temperature is lower than a second set temperature.

Vehicle battery temperature control apparatus

A battery-pack storage structure includes: a battery-case upper part configured to store a battery stack; a battery-case lower part; and a cooling air path through which cooling air for cooling the battery stack flows. The battery-case upper part is disposed on the battery-case lower part, and a bottom-part cooling air path, through which the cooling air flows, is formed between a bottom surface of the battery-case upper part and a bottom surface of the battery-case lower part.

Battery-pack storage structure

There is provided a vehicle battery pack protective structure which protects a vehicle battery pack including battery stacks disposed in a width direction of a vehicle. The structure includes: a battery pack storage container that stores the vehicle battery pack; and a first upper reinforcing member that extends in a front-rear direction of the vehicle between the battery stacks, and is connected to the battery pack storage container at a front end and a rear end. A first fragile part is formed below an intermediate position of the first the upper reinforcing member.

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.

Onboard battery for vehicle

An onboard battery includes an accommodation case that has an upper accommodation unit and a lower accommodation unit positioned below the upper accommodation unit battery modules each having battery cells, and joints that couple the upper accommodation unit and the lower accommodation unit to each other. At least one battery module is accommodated in each of the upper accommodation unit and the lower accommodation unit. When a predetermined load or more is applied to the upper accommodation unit, a stress acts on the joints such that the upper accommodation unit and the lower accommodation unit are separated from each other, and the upper accommodation unit is moved away from the lower accommodation unit.

Onboard battery

An onboard battery includes an accommodation case that has a hollow cross section formed with multiple cavities, and at least one battery module that has at least one battery cell and is accommodated in the accommodation case. At least one disposition depression that communicates with one of the multiple cavities and is opened upward is formed in a portion positioned below the at least one battery module in the accommodation case, and at least one heater that heats the at least one battery cell is disposed in the at least one disposition depression so as not to be in contact with the at least one battery cell.

A vehicle approach informing device includes: an informing sound output unit mounted on a vehicle and configured to inform of approach of the vehicle by transmitting sound to the outside; a distance measurement unit to detect a current position of the vehicle and to measure a distance between the detected current position and a predetermined position; and a sound volume control unit configured to set a sound volume outputted by the informing sound output unit to a predetermined normal sound volume when the distance measured by the distance measurement unit is equal to or longer than a first distance, and to set the sound volume to a lower level than the normal sound volume when the distance measured by the distance measurement unit is shorter than the first distance.

Vehicle approach information device with volume control

A battery system for a vehicle.
