While the process of charging an EV may not be as swift as refueling with gasoline (at least not yet), it is becoming more convenient and quicker than ever, thanks to the introduction of liquid cooling rapid chargers.

It only takes a few minutes to charge your electric vehicles

     EV quantity is getting ahead of IEC(internal engine combustion) vehicle

As the world shifts towards a sustainable future, electric cars are becoming increasingly popular. However, one of the biggest concerns among potential EV owners is how long it takes to charge their vehicle While the process of charging an EV may not be as swift as refueling with gasoline (at least not yet), it is becoming more convenient and quicker than ever, thanks to the introduction of liquid cooling rapid chargers.                   

Charging anxiety plagues EVs owners

The faster you charge an electric vehicle (EV), the more essential thermal regulation becomes. Higher power allows for quicker charging, but it also results in the production of a significant amount of heat. As electricity travels from the charging station through the charging cables and into the vehicle's battery cells, the internal resistances encountered by the higher currents are responsible for this substantial heat generation. Consequently, traditional charging stations that employ forced air cooling typically do not operate at very high power levels.

The liquid cooling charging station has a long service lifetime

Compared with the traditional forced air cooling charging station, the liquid cooling charging station can completely isolate the inside of the module from the external environment, avoiding direct contact between internal electronic components and external dust, salt spray, flammable and explosive gases and other impurities. The protection level reaches IP65, has the advantages of good environmental adaptability and no noise, and effectively reduces product failures caused by the external environment.

In particular, environmental factors such as high altitude and changeable climate have brought many difficulties to the construction of charging stations. Compared with traditional solutions, liquid-cooled supercharging stations are twice as reliable and have a service life of more than 15 years, making them fully adaptable.

Liquid cooling charging solution is suitable for projects

Liquid cooling charging solution is suitable for high-temperature environment

Liquid cooling systems are suitable for extreme high-temperature scenarios. Because the indoor and outdoor temperature difference is small under extreme high temperatures, the heat exchange efficiency of the air-cooling system deteriorates, which in turn leads to a decrease in cooling power of the air-cooling system. Ultimately, it cannot meet the temperature control needs of the project. However, the liquid cooling system can continuously maintain the cooling power online to ensure the normal operation of the system, so it is appropriate to use a liquid cooling system.

Generating a large volume of heat

Projects generating a large volume of heat should use liquid cooling systems. Because the high capacity and high system power density of energy-based energy storage (new energy power stations, off-grid energy storage) and the high-performance requirements of power-based energy storage will increase the amount of heat generated (such as power generation projects with large installed capacity regulation). For grid-side projects with high requirements, and the air-cooling system cannot meet the temperature control needs of such scenarios, a liquid-cooling system is suitable.

Liquid cooling charging solution is suitable for harsh environments

Liquid cooling systems are suitable for harsh environments such as seaside high-salt land and deserts. Because the air-cooling system has low integration and many parts, system components are easily corroded by high-salt water vapor and sand, leading to an increase in the system failure rate. However, the high integration of the liquid-cooling system can significantly reduce the failure rate compared to air cooling, so it is appropriate to use a liquid cooling system.

Liquid cooling charging solution could be a bad choice

However, the liquid cooling charging solution is not a perfect solution. And in some cases, the air-cooled charging pile solution is an irreplaceable option. For example, air cooling systems are suitable for extreme low-temperature scenarios. Liquid-cooling systems may freeze pipes and coolant in extremely low-temperature environments, or even pipe ruptures, while air-cooling systems can effectively avoid such undesirable phenomena and ensure the normal operation of the system. What’s more, the liquid cooling charging system is much more expensive than forced air cooling system. So projects generating low heat should use air cooling systems. The air-cooling system can meet the basic needs of the projects, such as ordinary ground charging stations and energy-storage-charging stations, so there is no need to use liquid-cooled charging pile solutions.

Finale

DC fast charging and extreme fast charging systems are imperative to reduce charging times and alleviate concerns associated with the rapid adoption of electric vehicles (EVs). These systems, operating at elevated power levels measured in kilowatts (kW), rely on liquid cooling technology to effectively disperse the heat generated during the charging process. This approach facilitates swift and efficient EV charging solutions, thereby addressing the growing need for faster charging options and easing range anxiety in EV users.
