Title
(EN) BATTERY COOLING SYSTEM

Abstract
(EN)
This battery cooling system for cooling a battery (2) for running a vehicle is provided with: a cooling liquid (12) for cooling the battery; a circuit (14) through which the cooling liquid flows; and a control unit (60). The circuit has a cooler (20) that cools the battery through heat exchanging between the battery and the cooling liquid, a radiator (22a) that radiates the heat of the cooling liquid to the outside of the circuit, and flowrate adjustment units (34, 36) for adjusting the flowrate of the cooling liquid flowing through the radiator. The control unit controls the flowrate adjustment units so as to reduce the flowrate of the cooling liquid flowing through the radiator when the conductivity of the cooling liquid increases.

La présente invention concerne un système de refroidissement de batterie permettant de refroidir une batterie (2) destinée à faire fonctionner un véhicule, comprenant : un liquide de refroidissement (12) servant à refroidir la batterie ; un circuit (14) à travers lequel s'écoule le liquide de refroidissement ; et une unité de commande (60). Le circuit comprend un refroidisseur (20) qui refroidit la batterie par échange thermique entre la batterie et le liquide de refroidissement, un radiateur (22a) qui rayonne la chaleur du liquide de refroidissement vers l'extérieur du circuit, et des unités de réglage de débit (34, 36) servant à régler le débit du liquide de refroidissement s'écoulant à travers le radiateur. L'unité de commande commande les unités de réglage de débit de façon à réduire le débit du liquide de refroidissement s'écoulant à travers le radiateur quand la conductivité du liquide de refroidissement augmente.
