US 2019/0319319 A1 · BATTERY COOLING DEVICE FOR ELECTRIC VEHICLE

Abstract

In a battery cooling device for an electric vehicle, a cooling medium supply piping and a cooling medium discharge piping are disposed in a fore-and-aft direction in a middle part in a vehicle width direction of a vehicle body. A plurality of cooling members extend toward opposite sides in the vehicle width direction from both the pipings. A cooling medium passage returns in an outer end part in the vehicle width direction of the cooling member. Therefore, when the vehicle is involved in a side collision, it becomes difficult for both the pipings to be damaged, and cooling medium is prevented from leaking. Also, the cooling medium flows by making a U-turn inside the cooling member, thereby enabling positions on outside and inside in the vehicle width direction of a battery to be cooled evenly.
