A power consumption control device includes: a storage battery; a heating unit; a storage unit storing a combination of a temperature of the storage battery and a remaining capacity of the storage battery in association with an increase amount in an effective capacity of the storage battery when the storage battery is heated by the heating unit which is supplied with each of the heating powers; a control unit configured to determine a first power which can be charged to the storage battery and to distribute the first power to the storage battery and the heating unit so that the increase amount in the effective capacity of the storage battery is maximized based on the first power, the increase amount for each of heating powers corresponding to the temperature of the storage battery and the remaining capacity of the storage battery, and the heating powers.

Power consumption control device

A cooling apparatus includes: a cooling circuit that includes three flow passages intersecting at an intersection point and allows a cooling liquid to circulate therethrough; a three-way valve that is disposed at the intersection point and is switchable such that any two of the three flow passages communicate with each other; and a controller that controls switching of the three-way valve. The controller includes an intermediate fixation determination unit. The intermediate fixation determination unit determines that the three-way valve is in an intermediate fixation state in which the three flow passages simultaneously communicate with one another, when a cooling liquid temperature difference between one of the two flow passages that are controlled to communicate with each other, and a remaining flow passage of the three flow passages that is not controlled to communicate, is smaller than a predetermined value.

Cooling apparatus capable of determining valve malfunction

A heating control device includes: a storage battery that supplies electric power to an electric motor of an electric vehicle; a heat generation portion that heats the storage battery using heat generated by current flowing; an estimation portion that estimates a change in effective capacity when the heat generation portion heats the storage battery to a target temperature using heat generated by current flowing due to electric power supplied from the storage battery based on an effective capacity corresponding to a temperature and a state of charge of the storage battery; and a controller that causes current flowing from the storage battery to the heat generation portion only in a case where the effective capacity estimated by the estimation portion is expected to be improved.

Heating control device

A power consumption control device includes: a storage battery configured to supply power to an electric motor of a plug-in electric motor vehicle; a heating unit configured to heat the storage battery using heat generated through current flowing; a power conversion unit configured to convert power supplied from an external power supply; an estimation unit configured to estimate a change in effective capacity of the storage battery when the heating unit generates heat through current flowing by the power supplied from the external power supply and raises the temperature of the storage battery to a target temperature, based on an effective capacity corresponding to the temperature and SOC of the storage battery; and a controller configured to control usage of the power converted by the power conversion unit according to the change of the effective capacity, estimated by the estimation unit.
