Abstract: A thermal management device includes two or more heat dissipation devices that dissipate heat into a heat medium, a heat medium-air heat exchanger that exchanges heat between air and the heat medium having its heat dissipated in the two or more heat dissipation devices, a flow-rate adjustment device that adjusts a flow rate of the heat medium flowing through the heat dissipation device, and a control unit. The control unit controls an operation of the flow-rate adjustment device to increase the flow rate of the heat medium flowing through the one heat dissipation device, if the control unit estimates an increase in the amount of heat dissipation into the heat medium at the one heat dissipation device of the two or more heat dissipation devices.

Abstract: A heat pump system includes a heat pump cycle, a heating unit, a low-temperature side heat medium circuit, and a control unit. The heat pump cycle includes a compressor, a condenser, and an evaporator. The heating unit heats ventilation air with heat released form refrigerant in the condenser. The low-temperature side heat medium circuit circulates a low-temperature side heat medium such that the refrigerant in the evaporator absorbs heat of the low-temperature side heat medium, and includes a heat source device and a heat amount adjustment unit. The control unit causes an amount of heat transfer in the heating unit for heating the ventilation air to approach a predetermined target value via adjustment in temperature of the low-temperature side heat medium by controlling a rotation speed of the compressor and an operation of at least one of the heat source device and the heat amount adjustment unit.

Abstract: An energy manager serving as a battery management device manages a state of a driving battery mounted on a vehicle. The battery management device includes a temperature adjustment unit, an environmental information acquisition unit, a temperature estimation unit, a target temperature setting unit, and a travel speed adjustment unit. The target temperature setting unit sets a target battery temperature at which the battery can be efficiently charged by operating the temperature adjustment unit when the vehicle arrives at a charging facility. The travel speed adjustment unit uses battery temperature estimated by the temperature estimation unit and target battery temperature set by the target temperature setting unit to determine an adjustment amount of a travel speed when the vehicle travels to the charging facility.
