Abstract: A heat management system includes a high-temperature heat medium circuit, a low-temperature heat medium circuit, a circuit connection part, and a circuit switching part. The high-temperature heat medium circuit connects a heat medium and refrigerant heat exchanger and a heater core. The low-temperature heat medium circuit connects a radiator and a heat generation equipment. The circuit connection part connects the high-temperature heat medium circuit and the low-temperature heat medium circuit such that the heat medium can flow in and out. The heat management system is switched by the circuit switching part between an operation mode in which the heat medium heated by the heat medium and refrigerant heat exchanger is circulated through the heater core and an operation mode in which the heat medium heated by the heat generation equipment and the heat medium and refrigerant heat exchanger is circulated through the heater core.

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.
