Development of efficient air-cooling strategies for lithium-ion battery module based on empirical heat source model

A controller of a thermal management system for a vehicle controls a first switching valve and a second switching valve to set a battery warming-up state in which a heat medium circulates between a battery-temperature adjustment heat exchanger and a heat-medium heating heat exchanger, and the heat medium does not circulate between a coolant-coolant heat exchanger and a heat-medium heating heat exchanger when both a battery and an engine need to be warmed up. In contrast, the controller controls the first switching valve and the second switching valve to set an engine warming-up state in which the heat medium circulates through between the coolant-coolant heat exchanger and the heat-medium heating heat exchanger while the heat medium does not circulate between a battery-temperature adjustment heat exchanger and the heat-medium heating heat exchanger when a temperature of the battery exceeds a target battery warming-up temperature in the battery warming-up state.

Thermal management system for vehicle

A rear seat is foldable by moving downward a seat cushion and folding forward a seat back. A power source unit is disposed below a rear floor to the rear of the rear seat. When the rear seat is in an unfolded state, cooling air can be introduced from inside a vehicle compartment, through a space between a lower surface of the seat cushion and an upper surface of an underseat floor, into a cooling-air introduction port in the power source unit. When the rear seat is in a folded state, the cooling air is introduced from inside the vehicle compartment, through cooling-air introduction passages, into the cooling-air introduction port. Thus, the power source unit can be cooled irrespective of whether the rear seat is in the folded state, without reducing the foldability of the rear seat.

Electrical device cooling structure in vehicle

A battery assembly has a temperature control mechanism for effecting cooling or heating unit batteries for operation in a desired temperature range. First heat-exchange planar members of respective heat-transfer plates are sandwiched between the unit batteries that are arranged in an array, and second heat-exchange planar members thereof are held against transverse narrow side walls of the unit batteries. The unit batteries and the heat-transfer plates are securely fastened together by holder plates. Heat produced when the unit batteries are in operation is transferred through the first and second heat-exchange planar members of the heat-transfer plates and dissipated into an appropriate cooling medium, such as atmospheric air or another cooling fluid, through a heat-exchange.

Battery assembly with temperature control mechanism

A battery box housing a battery is mounted between left and right side frames extending in a longitudinal direction of a vehicle body so that the battery box is offset to a left side of the vehicle body, and an intake duct and an exhaust duct for cooling air for cooling the battery are connected to an end of the battery box on a right side of the vehicle body. Therefore, it is possible not only to protect the battery between the left and right frames from a shock caused upon a side collision, but also to ensure a space for disposition of the intake duct and the exhaust duct while ensuring a volume of the battery box to the maximum. Moreover, the battery box is connected at its left and right ends to the left and right side frames.
