Embodiment Construction

[0052] figure 1 A motor vehicle 2 is shown, for example of the all-electric or hybrid type, connected to a power source 15 for recharging the battery. According to this example, the power source 15 makes it possible to recharge the traction battery 3 of the motor vehicle 2 . Traction battery means any energy storage device capable of generating the starting power of a motor vehicle. The motor vehicle comprises electrical connection means 10 in order to transmit the electric power provided by the power source 15 towards the motor vehicle 2 , in particular towards the traction battery 3 .

[0053] In this case, the power source 15 is a fast charging station delivering substantially 350 kilowatts (kW). Of course, the power source 15 could also be a system for regenerative energy during braking or deceleration of the vehicle or a household grid port allowing the traction battery 3 to be charged normally.

[0054] More precisely, the electrical connection device 10 is integral w...

Abstract

A circuit (1001, 1002, 1003, 1004) of a refrigerant fluid (700) of a vehicle (2) comprises: a compressor 200 intended to raise the pressure of the refrigerant fluid (700); a condenser 300, 301 locateddownstream of the compressor according to a circulating direction of the refrigerant fluid in the circuit (1001, 1002, 1003, 1004); an expansion member 401, 402, 403 located downstream of the condenser (300, 301), which is intended to lower the pressure of the refrigerant fluid; and an evaporator 600, 601 located downstream of the expansion member. This circuit comprises a heat exchanger 900 dedicated to cooling a charge port located on the vehicle and / or an interconnect located on the vehicle linking an electrical source and a battery to be charged.

Description

technical field [0001] The invention relates to the field of charging motor vehicle batteries, in particular traction batteries for hybrid or electric motor vehicles. Traction battery means any energy storage device that makes it possible to generate power for a motor vehicle. The subject of the invention is a heat exchanger and the associated cooling circuit intended to cool the electrical connections located on the vehicle that allow charging of such a battery. Background technique [0002] The traction battery can be charged via the electrical connection. The first type of charging is called fast charging and is used by dedicated stations configured to deliver direct current, for example. For this purpose, the charging cable connected to the station is equipped with a pistol-type plug, which connects to the charging port of the vehicle. For example, by delivering 120 amps of direct current, this type of station can fully charge a traction battery in 20 to 30 minutes. ...
