20130059191 | BATTERY TEMPERATURE ADJUSTMENT DEVICE - A structure for effectively heating a battery. A battery is housed in a battery container. A condenser is formed such that a heating medium is in direct contact with a surface of the battery container, and condenses the heating medium to heat the battery via the battery container. The heating medium condensed by the condenser is supplied to an evaporator that heats and vaporizes the heating medium. The heating medium vaporized by the evaporator which is in vapor is circulated to the condenser. | 03-07-2013 |
20130234511 | BUS BAR MODULE, VEHICLE POWER SOURCE APPARATUS, AND VEHICLE - A bus bar module has a bus bar housing portion housing a plurality of bus bars placed side by side in a first direction, and a plurality of voltage detecting lines extending in the first direction and each connected electrically to a different one of the bus bars through a conductive member. The plurality of voltage detecting lines are placed adjacently to the bus bar housing portion and are placed diagonally in a second direction inclined relative to an in-plane direction including the bus bar such that a first region in the plurality of voltage detecting lines separate from the bus bar housing portion is located below a second region in the plurality of voltage detecting lines closer to the bus bar housing portion. | 09-12-2013 |
20140038020 | POWER STORAGE APPARATUS - A power source apparatus having an assembled battery including a plurality of batteries of cylindrical shape arranged in a diameter direction of the battery within a case includes a holding member which holds the plurality of batteries from the diameter direction and is in contact with the inner face of the case to divide the internal space of the case into a cooling path in which a coolant flows and a gas discharge path in which gas is discharged from the battery in a battery abnormality, wherein the holding member is a solid plate member conducting heat of the battery. | 02-06-2014 |
20140134470 | BATTERY PACK - A battery pack includes a plurality of battery modules; at least one space that is formed between the battery modules that are adjacent to each other, and that serves as a flow path for a heat carrier; and a plurality of protrusions that protrude toward an inside of the space, and that are arranged on surfaces of opposing surfaces that oppose each other and that define the space. The plurality of protrusions that are arranged on one surface of the opposing surfaces and the plurality of protrusions that are arranged on the other surface of the opposing surfaces are arranged in positions that oppose each other across the space. | 05-15-2014 |
20140154538 | BATTERY PACK - A battery pack includes a space as a heat carrier flow path that is formed between the adjacent battery modules; and protrusions that protrude toward an inside of the space, and that are arranged on surfaces of opposing surfaces and that define the space. The protrusions have a longitudinal direction when viewed from a protruding direction. The plurality of protrusions arranged on one surface of the opposing surfaces and the plurality of protrusions arranged on the other surface of the opposing surfaces are arranged in positions that are offset, in a flow direction of the heat carrier, from positions that oppose each other across the space. The longitudinal direction of the protrusions arranged on the one surface and the longitudinal direction of the protrusions arranged on the other surface are inclined in the same direction, with respect to the flow direction. | 06-05-2014 |
20140287281 | POWER STORAGE DEVICE AND BATTERY TEMPERATURE REGULATING METHOD - A power storage device includes a case in which at least one unit cell is housed; a heat exchanger ( | 09-25-2014 |
20140356666 | BATTERY CASE AND VEHICLE - A battery case within which a battery is housed includes a first layer that is made of metal, a second layer that is made of heat insulating material, and a third layer that is made of phase-change heat storage material. The second layer is closer to the battery than the first layer is. The third layer is closer to the battery than the second layer is. | 12-04-2014 |
20150007583 | TEMPERATURE ADJUSTMENT APPARATUS AND METHOD OF CONTROLLING PELTIER ELEMENT - A temperature adjustment apparatus has a Peltier element supplied with electric power to allow heat exchange between an electronic device mounted on a vehicle and a heat exchange portion of the vehicle, and a Peltier element control section that controls electric power supplied to the Peltier element. When the temperature difference between a first surface of the Peltier element serving as an exothermic surface and a second surface of the Peltier element serving as an endothermic surface becomes larger than a first predetermined value as a result of supply of electric power to the Peltier element, the Peltier element control section stops supply of electric power to the Peltier element. | 01-08-2015 |
20150042284 | CONTROL APPARATUS FOR VEHICLE BATTERY AND CONTROL METHOD FOR VEHICLE BATTERY - A control apparatus for a vehicle battery having a first battery and a second battery connected in parallel is provided. Each of the first and second batteries is provided with a relay operating between an allowing state in which charge from the power supply section is allowed and in a non-allowing state in which the charge is not allowed. The control apparatus includes a controller performing charge processing in which, when a voltage difference exists between the first battery and the second battery, the relay provided for one of the batteries having a lower voltage is set at the allowing state to charge only the one of the batteries, and when the charge causes the voltage of the one of the batteries to be equal to the voltage of the other of the batteries, both the relays provided for the one and the other of the batteries are set at the allowing state to charge the one and the other of the batteries. | 02-12-2015 |
