According to the data of an authoritative Association, the production and sales of new energy vehicles in China from January to July this year were 3.279 million and 3.194 million respectively, with a market share of 22.1% and a year-on-year growth of 120%. The production of new energy vehicles will maintain a rapid growth. With the continuous explosion of new energy vehicles in China, as an important basis for promoting the sustainable development of new energy vehicles, the number of electric vehicle charging piles is also increasing. According to the latest data released by the national energy administration, 1.3 million new charging piles were added from January to June this year, 3.8 times that of the same period last year. Electric vehicle charging piles are regarded as one of the key directions for the construction of new infrastructure in domestic cities.
With the rapid development of the electric vehicle industry and the innovation and breakthrough of the charging pile technology, the waiting time for charging becomes shorter and shorter, thus helping the sales of electric vehicles to rise. As the charging time becomes shorter, the charging pile also faces a serious problem. While charging rapidly, the charging pile needs higher current to meet the requirements of faster charging, which will lead to the over temperature protection of the module due to the high temperature of the charging pile. Therefore, the charging pile has more stringent requirements for heat dissipation.
The common fan heat modes of charging pile include air-cooled fan heat and liquid cooled fan heat. With the higher requirements of charging pile for heat dissipation, the traditional air-cooled heat dissipation can no longer meet the large heat dissipation of charging pile. The excellent heat dissipation mode of liquid cooling can just solve the large fan heat problem of charging pile and meet the development opportunity of charging pile.
The excellent fan heating mode of liquid cooling is due to the performance of the internal core accessory - water pump.
Thermal principle of charging pile liquid cooling fan: a special circulation channel is set between the cable and the charging gun. The channel is filled with cooling liquid with heat dissipation effect, and then the liquid is circulated by the water pump to bring out the heat, which plays a good role in reducing the heat of the fan. Therefore, an excellent water pump can not only improve the fan thermal performance of the charging pile, but also improve the charging performance of electric vehicles.
How should we choose the charging pile pump?
1.The quality and performance of charging pile water pump with vehicle specification level are better. Shenpeng charging pile water pump has passed the strict ISO9001, iatf16949, ISO14001, OHSAS18001 and other system certification in the industry, and its quality and quality are more guaranteed.
2. Select the water pump manufacturer cooperating with large-scale automobile enterprises to control the production of charging pile water pump more strictly. Shenpeng officially entered the automotive field in 2011. At present, it has developed more than 30 products of 20-30w, 40-130w and 200-300w series. It has cooperated with Dongfeng, FAW, Shaanxi Automobile, BAIC, Zhengzhou Nissan, Geely, Chery, Yijie, BAIC, BYD, Chang'an Automobile, Great Wall Motor, Jiangling Automobile, SAIC general Wuling, lead, Hezhong and other large domestic automobile enterprises.
3. Choose a variety of certified water pump manufacturers, external support is more assured. The products produced by Shenpeng have passed CE, ROHS, reach and TSCA certification, and some products have obtained UL and FDA food grade certification.
As one of the earliest companies in China to develop DC brushless water pumps, Shenpeng has 18 years of industrial production and R & D experience. It has CNAs standard laboratory, 300000 level dust-free workshop, 10 professional production lines of electronic water pumps, etc. Shenpeng charging pile water pump protects your charging pile heat dissipation.
