There are actually not many components that limit the development of fast charging for new energy vehicles. The car part is dominated by the power battery. And the charging pile part is the charging cable, EV charging cable power, heat dissipation, volume, cost and many other factors are required to consider the development of fast charging. How to meet the high power under the condition of small volume and relatively low cost, and reduce the safety hazards while dissipating heat, the solution that has been recognized by the market at this stage is EV DC fast charging liquid-cooled cable.
Compared with the traditional air-cooled, cables with liquid-cooled technology have better heat dissipation efficiency and can break through to higher charging power while significantly reducing the volume, and relatively speaking, the material cost is also lower, but the R&D cost of high-power liquid-cooled cables is relatively high. For example, the high-power liquid-cooled charging cable produced by FAFA-E cost the R&D team a lot of time and energy and financial resources, the charging pile body only needs to be liquid-cooled transformation is not complicated, the new energy vehicle charging cable line is the core component of the charging pile, which is very important now and in the future when DC fast charging becomes just necessary.
FAFA-E produces high power DC charging cable with liquid cooling technology, adding liquid cooling circulation system inside the cable to realize cooling and cooling, so that the cable can be charged at a relatively low temperature, overcoming the thermal damage to the charging connector, the charging cable itself and the charging pile caused by the heating of the cable, enabling fast recharge in a short time and eliminating user charging anxiety.
The technical difficulty of liquid-cooled heat dissipation lies in the sealing of the coolant. The environment faced during the whole installation and use of the charging pile may be harsh, and may even be disturbed by other factors, and if the coolant and the cable are not strictly sealed, it may lead to the breakage of the internal pipes of the cable and the failure of the whole cooling system, which may easily cause safety accidents in serious cases. Therefore, liquid-cooled cables need to pass the test of high and low temperature resistance, corrosion resistance, explosion resistance, weather resistance and other items, and the products can be shipped only after passing the test.
FAFA-E is a professional R&D company of EV charger, which pays attention to the industry dynamics in real time and closely liaises with domestic and foreign charging post companies and connector companies, and has continuously developed various forms of EV charging cables to meet the diversified needs of the market.
