Embodiment Construction

[0023] Hereinafter, embodiments of the present invention will be described with reference to the drawings. In order to facilitate understanding of the description, in each drawing, the same components are assigned the same reference numerals as much as possible, and repeated descriptions are omitted.

[0024] like figure 1 As shown, the battery preheating system 1 of the first embodiment has: a high temperature side water circuit 10 , a refrigerant circuit 11 , a low temperature side water circuit 12 , and a control device 13 .

[0025] The high temperature side water circuit 10 has: a water-cooled condenser 101 , an air conditioner heat exchanger 102 , a battery heat exchanger 103 , a pump 104 , a water temperature sensor 105 , an air conditioner blower 106 , and a battery blower 107 .

[0026] In the high-temperature side water circuit 10, the warm water generated in the water-cooled condenser 101 is distributed to the air-conditioning heat exchanger 102 and the battery hea...

Abstract

A battery warm-up mode for controlling at least one of an air conditioner fan 106 and a battery fan 107 is executed so that the air side temperature efficiency of an air conditioner heat exchanger 102becomes higher than the air side temperature efficiency of a battery heat exchanger 103.

Description

[0001] Cross-reference of related applications [0002] This application is based on Japanese Patent Application No. 2015-219621 filed on November 9, 2015, and Japanese Patent Application No. 2016-196184 filed on October 4, 2016, and claims the benefit of priority. All contents of these patent applications are hereby referred to incorporated into this manual. technical field [0003] The invention relates to a battery preheating system. Background technique [0004] As a battery warm-up system for warming up a battery mounted on a vehicle mainly at the initial stage of starting, a configuration described in Patent Document 1 below is known. The battery warm-up system described in Patent Document 1 below is a refrigeration cycle device that adjusts the temperature of the air sent out for battery warm-up while adjusting the temperature of the air sent to the space to be air-conditioned. [0005] The refrigeration cycle device described in the following Patent Document 1 incl...
