Description
Technical Field
The utility model relates to an electric automobile battery charging outfit technical field, concretely relates to liquid cooling cable that electric vehicle european standard direct current charging socket was used.
Background
The electric vehicle is rapidly developed due to no exhaust emission and no environmental pollution, and the two main factors for restricting the development of the electric vehicle are as follows: firstly, the battery has short cruising ability; secondly, the charging duration. The problem of short battery endurance has been solved; the problem of long charging time is expected to be solved.
At present, European standard liquid-cooled DC charging guns and liquid-cooled cables used by the same are published. The liquid-cooled DC charging gun can safely carry charging current between 300 and 600 amperes of DC. The quick charging is a system engineering, only a large-current direct-current charging gun cannot operate, and the quick charging can be realized only by a large-current direct-current charging socket matched with the large-current direct-current charging gun.
If a direct current charging socket on the electric vehicle cannot bear the charging current between 300 and 600 amperes of direct current, ideal rapid charging cannot be realized; if the direct-current charging socket of the electric vehicle can safely bear the charging current between 300 and 600 amperes of direct current, a liquid cooling cable which is suitable for the direct-current charging socket and can bear 300 to 600 amperes of direct current is needed, and the liquid cooling cable not only can realize the heat dissipation and cooling of a bus by circulating flowing cooling liquid; moreover, the conductive terminals in the socket connected with the bus bar are also required to be cooled by heat dissipation of the cooling liquid which flows circularly; if the conductive terminals of the direct current charging socket and the soft wires connected with the tail parts of the conductive terminals do not need cooling and radiating by circulating flowing cooling liquid, and if the conductive terminals of the soft wires and the conductive terminals of the socket need to safely bear the charging current between 300 and 600 amperes of direct current, the cross section of the soft wires and the diameters of the conductive terminals need to be increased, so that raw materials are wasted, and the wiring space in a vehicle is not suitable for the heavy cable; the industry standard also does not allow the form and position size of the conductive terminals of the direct current charging socket to be increased.

The socket and the cable connected with the tail part of the socket can only carry 200 amperes of direct current, so that the charging speed is slow. The charging status is eagerly expected to be changed by vehicle enterprises and vehicle owners.
In the aspect of solving the problem of rapid charging of electric vehicles, engineering technicians in various countries do a great deal of research and practice work, and the progress is still considerable. At present, in the field of charging of European electric vehicles, a 350-kilowatt direct-current charging pile is published; a matched DC 400-ampere European standard liquid-cooled DC charging gun is also known.
However, a direct current charging socket which can be matched with a direct current 400 ampere European standard liquid cooling direct current charging gun must be installed on the electric vehicle; and the special liquid cooling cable matched with the DC 400 ampere European standard DC charging socket can realize quick charging.
If the conducting terminals in the European standard DC charging socket and the soft wires connected with the tail part of the European standard DC charging socket are dry-type and not liquid-cooled, the conducting terminals in the European standard DC charging socket and the soft wires connected with the tail part of the European standard DC charging socket are not easy to dissipate heat generated in the charging process if the European standard DC charging socket bears the charging current between 300 and 600 amperes, accidents can be caused due to overheating, and serious people can cause fire disasters and burn out vehicles.
The European standard direct current charging socket can use a liquid cooling cable, the liquid cooling cable not only can well dissipate heat of the soft conductor of the liquid cooling cable, but also can well dissipate heat of the liquid cooling of the conductive terminal connected with the soft conductor of the liquid cooling cable, so that the European standard direct current charging socket can bear the charging current between 300 amperes and 600 amperes in the charging process, cannot be overheated, and is beneficial to solving the problem of quick charging.
