Abstract:
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.
Abstract:
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.
