With the rapid development of the electric vehicle industry, charging piles, as key infrastructure, have attracted much attention for their technological innovation. Among the many technologies that improve the performance of charging piles, the EV charging pile liquid cooling pump stands out as a core component that solves heat dissipation problems during charging and enhances charging efficiency and safety. This article will delve into the technical principles, application scenarios, advantages, and industry development trends of EV charging pile liquid cooling pumps.

1. Technical Principles

During the charging process of EV charging piles, especially during high-power fast charging, a large amount of heat is generated. If heat cannot be dissipated in a timely manner, it will not only affect charging efficiency but also may damage equipment and even cause safety issues. Liquid cooling technology has emerged, which works by using a circulating fluid to flow through a closed channel, taking away the heat generated during charging. The EV charging pile liquid cooling pump is the power source of this circulation system. Driven by a motor, it enables the cooling fluid to circulate among heat-generating components such as charging modules, cables, and charging guns, achieving efficient heat dissipation.

Taking a common DC charging pile as an example, the liquid cooling system usually consists of a liquid cooling pump, a radiator, cooling fluid, and pipes. When the charging pile is working, the liquid cooling pump draws the cooling fluid from the radiator, pressurizes it, and delivers it to the liquid cooling plate of the charging module. After the cooling fluid absorbs the heat generated by the module, its temperature rises, and then it flows back to the radiator. In the radiator, the heat is dissipated into the surrounding environment through a fan or natural convection. After the temperature of the cooling fluid drops, it is again delivered to the heat-generating components by the liquid cooling pump, and this cycle repeats.

2. Application Scenarios

2.1 DC Ultra-Fast Charging Piles

DC ultra-fast charging piles, with their high-power and fast-charging characteristics, have become an important means to alleviate the range anxiety of electric vehicles. However, high-power charging generates a lot of heat, which places extremely high demands on the heat dissipation system. The EV charging pile liquid cooling pump plays a key role in DC ultra-fast charging piles. Through efficient heat dissipation, it ensures that the ultra-fast charging piles can continuously and stably output high power, achieving fast charging. For example, Tesla's V3 supercharging piles adopt liquid-cooled charging cables, paired with high-performance liquid cooling pumps, which effectively reduce cable heating, improve charging efficiency, and significantly increase charging speed.

2.2 Public Charging Piles

Public charging piles are widely distributed and used frequently, requiring strict stability and reliability of the equipment. The application of liquid cooling pumps can reduce the heating problem of charging piles during frequent use, extend the service life of the equipment, and reduce maintenance costs. At the same time, their low-noise operation feature can also provide users with a more comfortable charging environment, which is especially suitable for charging piles in densely populated areas such as urban commercial districts and residential areas.

2.3 Highway Service Area Charging Piles

Charging piles in highway service areas need to meet the demand for fast charging of a large number of vehicles, and the charging power is usually relatively high. In this scenario, the EV charging pile liquid cooling pump can effectively cope with the high heat generated by high-power charging, ensuring the stability of the charging pile during long-term and high-load operation, and providing reliable charging guarantee for electric vehicles on long trips.

3. Advantages and Features

3.1 Efficient Heat Dissipation

Compared with traditional air cooling technology, the liquid cooling system driven by the liquid cooling pump has higher heat dissipation efficiency. The liquid has a large specific heat capacity, which can absorb more heat. Moreover, the cooling fluid circulates in closed pipes, making heat transfer more direct and efficient, which can quickly reduce the temperature of charging components to a safe range and ensure the stable operation of the charging pile.

3.2 Extended Equipment Lifespan

Continuous high temperature will accelerate the aging of internal electronic components of the charging pile and reduce the service life of the equipment. Shenpeng Technology's EV charging pile liquid cooling pump effectively reduces the risk of damage to electronic components due to overheating through efficient heat dissipation, extends the overall service life of the charging pile, and reduces equipment replacement and maintenance costs.

3.3 Lightweight Design

In the liquid-cooled charging system, because the liquid cooling pump can dissipate heat efficiently, the charging cable can be designed to be thinner and lighter. For example, the cable cross-sectional area of some liquid-cooled charging guns is much smaller than that of traditional air-cooled charging guns. While ensuring the current-carrying capacity, it reduces the weight of the charging gun, makes operation more convenient, and improves user experience.

3.4 Intelligent Control

Shenpeng Technology's EV charging pile liquid cooling pump usually has an intelligent control function, which can automatically adjust the pump's speed and flow according to the temperature change during charging. By linking with the control system of the charging pile, precise heat dissipation is achieved, which not only ensures the heat dissipation effect but also reduces energy consumption and improves the overall energy efficiency of the system.

3.5 High Reliability

Shenpeng Technology's EV charging pile liquid cooling pump has undergone strict design and testing, with good reliability and stability. The high-quality materials and advanced manufacturing processes used make it adaptable to various harsh environments, such as high temperature, low temperature, humidity, etc., ensuring normal operation in different regions and climatic conditions.
