Problems solved by technology

In parallel with the temperature control of the battery, when the air-conditioning control that adjusts the interior of the vehicle to an appropriate temperature based on the scheduled departure time is performed in parallel, both the battery temperature adjustment control and the air-conditioning control are performed while consuming the power of the battery, so the load on the battery increases. May reduce range

Embodiment Construction

[0046] Below, based on Figure 1 to Figure 6 Embodiments of the present invention will be described.

[0047] like figure 1 As shown, the electric vehicle is equipped with an electric motor 11 for running, and the battery 12 that supplies electric power to the electric motor 11 is charged by the electric power generated by the regenerative braking of the electric motor 11, and is connected to the battery through the charging cable when the electric vehicle is stopped. The external charging device 13 is connected to be charged. When the temperature of the battery 12 is too high or too low, the cruising distance of the electric vehicle will be shortened, so a battery temperature adjusting device 14 for heating or cooling the battery 12 to a suitable temperature is provided. The battery temperature regulator 14 operated by the electric power stored in the battery 12 heats the battery 12 by supplying warm air and warm water, and cools the battery 12 by supplying cold air and col...

Abstract

Provided is a power supply device for a vehicle that suppresses an increase in the load on a battery while achieving battery temperature adjustment control and air conditioning control. The power supply device for a vehicle includes a battery (12), an air conditioning device (15), a battery temperature regulating device (14), and a control device (16). The control device (16) includes an air conditioning control part (17) that starts operation of the air conditioning device (15) at an air conditioning start time preset by a user, and a battery temperature control part (14) that sets a batterytemperature regulation start time (t1) at which operation of the battery temperature regulating device (18) is started based on the air conditioning start time (t2) and a battery temperature. Therefore, not only is it possible to alleviate burden on the battery by shortening a state in which both the air conditioning device and the battery temperature regulating device are operating, but it is also possible to eliminate inconvenience for a user to set both the air conditioning start time and the battery temperature regulation start time.

Description

technical field [0001] The present invention relates to a battery for driving a vehicle, an air conditioner for air-conditioning the interior of a vehicle using the power of the battery, a battery temperature regulator for adjusting the temperature of the battery by using the power of the battery, and a combination of the air conditioner and the battery. A power supply unit for a vehicle with a control mechanism that controls the operation of the battery temperature regulator. Background technique [0002] In Patent Document 1 below, it is known that a control mechanism that controls charging of a storage battery of an electric vehicle operates a heater or a blower so as to operate a heater or a blower when determining the charging start time based on the scheduled driving start time of the vehicle and the state of the battery. The temperature of the storage battery at the start time satisfies a preset temperature condition, thereby completing charging of the storage battery...
