Description
Technical Field
The utility model belongs to the technical field of the electric automobile technique of charging and specifically relates to a European standard direct current rifle liquid cooling cable that charges is related to.
Background
New energy electric vehicles are rapidly developed all over the world due to no exhaust emission and no environmental pollution. The domestic new energy electric automobile is already out of the country and is sold all over the world. Meanwhile, China also imports a number of new energy electric vehicles in Europe. Whether the new energy electric automobile is a Chinese new energy electric automobile or a foreign new energy electric automobile, two main factors for restricting the development of the new energy electric automobile are provided at present: firstly, the battery has short cruising ability; secondly, the charging duration.
Compared with the national standard direct current charging gun in China, the direct current charging gun in the European standard has a completely different structure. The national standard DC charging gun in china has its DC +, DC-DC charging gun terminals male, while the european standard DC charging gun has its DC +, DC-DC charging gun terminals female. In addition, the definition of the signal lines is also different. The battery endurance of new energy electric vehicles in Europe is also increasing continuously, and household electric cars capable of endurance of 400 km after once charging are available. The quick charging is a problem which is urgently expected to be solved by vehicle enterprises and vehicle owners.
At present, the problem of quick charging is researched and solved at home and abroad, the thinking and the method are the same, the charging working voltage of the charging pile is improved as much as possible, and the charging output current of the charging pile is increased. For example, the charging working voltage of the charging pile is increased to 1000V, and the output current is increased to 400-600A. The power of the high-power charging pile is manufactured, and the technical problem does not exist. The problem that needs to be solved is the connection of high-power charging pile power to the charging gun. On the market, there are two specifications for the dry cable connected to the european standard dc charging gun: (1) a soft wire with the thickness of 35 square millimeters is arranged in the electric conduction device to carry current 125A. (2) A50 mm square soft wire is arranged in the device to carry current 160A. The soft conductors of the cable can only carry 125A-160A; obviously, the dry cable can not carry 300A-600A charging current, otherwise, the dry cable can cause fire and accidents. Increasing the cross-sectional area of a soft wire is theoretically possible, but not practical. Because of the large cross-sectional area of the flexible wire, the cable is bulky and heavy, which is not ergonomic. In addition, the soft lead and the jack terminal in the European standard DC charging gun have great difficulty in connection because the outer diameter size is different too much.
With the increase of export quantity of domestic new energy electric automobiles, the new energy electric automobiles exported to Europe need to meet the charging standard of Europe. Therefore, there is a need for a charging cable that can carry 300A-600A charging current and that meets the european standard dc charging gun standard, not only for ergonomic reasons, but also for safe and reliable long-term operation.
