- TITLE COOLING ELEMENT FOR ELECTRIC CHARGING CABLE OF AN ELECTRIC ENERGY STORAGE DEVICE AND METHOD FOR CORRESPONDING PLACEMENT.
- the present invention relates to the field of electrical charging of electrical energy storage devices of electric motor vehicles or thermal-electric hybrids. More particularly, the invention relates to electrical charging cables of such electrical energy storage devices which are likely to heat up during the vehicle charging operation.
- These electric and hybrid vehicles are propelled by an electric motor powered by electrical energy stored in batteries arranged in the vehicle.
- the batteries are supplied with electricity by connecting the electric vehicle to a charging station via an electric charging cable.
- new equipment has been put in place to allow ultra-fast charging (also called “Fast Charge” or “ultra fast charge” in English) of these batteries, i.e. say a full charge, or almost full, in a few tens of minutes. Thanks to this high-power charging technology and high current intensities, recharging an electric vehicle with electricity becomes comparable to refueling a combustion engine.
- the charging cables are subjected to high stresses, in particular to significant temperature rises. These temperature rises risk damaging the electrical charging cables as well as the connection elements, such as the adapter plugs, or even endangering the user who is required to grasp and handle the charging cables. .
- a known solution consists in increasing the section of the current-conducting elements of the electric charging cable. This solution has at least the disadvantages of reducing the flexibility and maneuverability of the cable, in particular by increasing its bulk and its weight.
- Another solution is to combine electrical charging cables with cooling systems. There are known electrical charging cables equipped with cooling fluid circulation pipes which follow the current-conducting elements of the cables or which are contained inside them with a view to cooling them by dissipating the heat generated. These cooling systems are not efficient enough compared to the amounts of heat emitted during ultra-fast charging.
