Charging piles belong to civil infrastructure, most of which are deployed in outdoor scenarios, and need to withstand the test of high dust, flying flocculent, heavy salt spray, and highly corrosive substances that are not conducive to equipment operation. The problem is that the equipment has a high failure rate. Unstable operation and other phenomena cannot be safely produced, and operators cannot get a good return on investment, which puts forward higher requirements for the safety and reliability of charging piles.
Therefore, liquid-cooled charging piles came into being.

Liquid cooling technology, the current mainstream of the charging pile market

The first batch of liquid-cooled charging piles are the V3 super charging piles launched by Tesla in 2020, which can achieve a maximum range of 250km after charging for 15 minutes, using liquid-cooling technology. The charging pile scheme announced by Tecom in early April this year also uses liquid cooling technology, which can increase the cruising range of the vehicle by 300km after 5 minutes of charging.
The liquid-cooled super charging pile series products adopt advanced thermal management concepts and cutting-edge power electronic technology, and have the characteristics of high protection level, high power density, high efficiency, high power factor, and strong environmental adaptability.
Compared with traditional charging piles, liquid-cooled charging piles have obvious advantages, which are mainly reflected in the following aspects:
1. Green energy saving: low standby power consumption, reducing the operating cost of operators; effectively reducing the input wire diameter and reducing costs; more efficiently delivering energy to users at the receiving end.
2. Strong environmental adaptability: no direct heat exchange with outside air is required, and it is protected from damage to power and electronic devices caused by external dust, salt spray, humidity and other unfavorable environments, especially in application scenarios where the above factors are relatively harsh.
3. High safety and convenient maintenance: The liquid cooling circuit is isolated from the electrical circuit, and the electrical and heat exchange compartments are designed separately. The electrical compartment is protected from adverse environmental erosion, and the accumulated dust in the heat exchange compartment can be directly washed.
4. High reliability and long service life: ensure the working environment temperature of electronic components and prolong the service life of modules and systems.

Liquid-cooled coolant pumps make charging piles more competitive
The principle of the liquid-cooled charging pile is not difficult to understand, that is, a special circulation channel is set between the cable and the charging gun, and the cooling liquid that can play a role in heat dissipation is added to the channel, and then the liquid circulation is pushed by the power pump to take away the heat. So, how to choose a liquid-cooled charging pile water pump?
The charging pile cooling circulating water pump produced by TOPSFLO Pump is suitable for different cooling applications such as super-charging pile liquid cooling cooling module and liquid cooling gun line. EV charging pump TL-B10, TL-C01, TL-C02, TA60 and other options are available , and can also provide professional customized services according to customer needs to meet all the liquid cooling needs of DC supercharged piles in the market. It has the following properties:
First, more “lighter” and “colder”. The diameter of the charging pile gun wire using the liquid-cooled water pump can be 50% smaller than that of the traditional gun wire, which saves more space, and at the same time, the weight is greatly reduced, and women can easily operate it. TOPSFLO liquid cooling water pump adopts international famous brand electronic components, uniquely designed PCB board, sufficient margin design of electronic scheme, low temperature rise, fast heat dissipation, remarkable cooling effect, and truly empowers “cold and fast” charging piles.
Second, adapt to the needs of different working conditions. Each TOPSFLO pump has undergone strict high and low temperature rapid switching tests of the whole machine, and has a wide temperature resistance range, so it is not afraid of extreme temperatures in severe cold and heat.
Third, the life span exceeds 30,000 hours and is maintenance-free. The charging piles arranged along expressways and highways and in remote areas require long-distance maintenance, and it is difficult for personnel to be in place in time. The advantages of TOPSFLO liquid-cooled water pumps, which are maintenance-free and have a lifespan much longer than that of ordinary water pumps on the market, can be fully utilized.
Fourth, multiple protections make charging more stable. TA60 has six safety protection functions of idling protection, locked-rotor protection, overcurrent protection, polarity protection, overvoltage protection, and constant power output, escorting high-efficiency liquid-cooled super charging piles.
As a pioneer brand of miniature brushless DC water pumps, TOPSFLO brand under TOPSFLO Pumps has realized water pump solutions in many fields such as car preheating, solar energy, plumbing mattresses, battery cooling, hot drink machines and other fields since its birth in 2005. The innovative breakthrough has won many praises from the market and customers. In the field of charging pile cooling, the liquid-cooled charging pile water pump developed and produced by TOPSFLO has also been widely praised by high-end charging pile manufacturers at home and abroad. It has reached long-term strategic cooperation with many well-known enterprises, and can provide professional and mature liquid-cooled charging piles. Water Pump Solutions. We look forward to working with more charging pile enterprises to contribute to the innovation and development of the industry!
