Abstract:
PROBLEM TO BE SOLVED: To provide a method for cooling and controlling a vehicle high-voltage battery which suppresses or prevents a temperature of the high-voltage battery from excessively rising when a vehicle is left in idling in the daytime having a lot of sunlight.SOLUTION: When it is determined that a cabin temperature in a vehicle may cause an excessive temperature of the high-voltage battery, proper control maximally suppresses the temperature rise of the high-voltage battery to improve the operation safety of the high-voltage battery.

PROBLEM TO BE SOLVED: To provide an electrical power train for a fuel cell vehicle. SOLUTION: The electrical power train comprises an electrical line 61; a fuel cell 3 connected to the electrical line 61 (wherein this fuel cell 3 includes a first cooling circuit 1 cooled with the use of a first heat-move liquid material and having a first radiator 10); an electrical energy management unit 6 comprising a control module of the fuel cell 3; a control device connected to the management unit 6 and available to the driver of the vehicle for controlling deceleration the latter; at least one electrical machine 4 connected to the electrical line 61 through the control module and connected to at least one driving wheel 40; an electrical dissipation element 8; and a means for, in the event of deceleration demand, and when the management unit 6 detects that the power absorbed by the auxiliary loads is less than the power sent over the electrical line 61, ordering the control module of the fuel cell 3 to stop the process of producing electrical energy while connecting the dissipation element 8 to the electrical line 61.

Abstract:
An engine (1) of a hybrid vehicle that is to be preheated before being started is connected to a heat accumulator (11) that stores a portion of a cooling water that is kept warmed. During cold start of the vehicle, when a temperature of the cooling water in the heat accumulator (11) is equal to or higher than a temperature of the cooling water in the engine (1) by a preset amount, the cooling water kept warmed in the heat accumulator (11) is fed into the engine (1). The motor (4) is driven to operate the vehicle until the engine (1) is sufficiently preheated.
Abstract:
PROBLEM TO BE SOLVED: To provide a temperature regulator for a storage battery, which sufficiently suppress temperature rise of the battery also preferable for warming up the battery. SOLUTION: The regulator comprises a first face 1 that radiates or absorbs heat responding to the polarity of energization and a thermoelectric converter having a second face 2. The first face 1 is thermally connected with at least one of the storage battery 8a or 8b and a second face 2 is thermally coupled with a thermal action promotion medium 4.
Abstract:
PROBLEM TO BE SOLVED: To provide a secondary battery system, and a vehicle equipped with the same for warming the secondary battery without consuming useless power, and taking out required power from the secondary battery even under low temperature environment. SOLUTION: The secondary battery system includes the secondary battery receiving regenerated power from a motor, a heat storage means converting power stored in the secondary battery or a part of the regenerated power from the motor to heat to store, and supplying the stored heat to the secondary battery if the temperature of the secondary battery is less than the preset low temperature side threshold value when taking out power from the secondary battery, and a power distribution control means distributing the regenerated power from the motor to the secondary battery and the heat storage means if the temperature of the secondary battery is less than the low temperature side threshold value when the secondary battery receives the regenerated power from the motor.
