ultra-quiet liquid-cooled charger is launched

A new era of charging! Hongjiali's ultra-quiet liquid-cooled charger is launched, leading a new era of ultra-fast charging!

In March 2025, Hongjiali New Energy Co., Ltd. announced that the domestic leading ultra-quiet liquid-cooled charger independently developed and produced by the company was officially launched. This series of 160KW chargers has been running for several months at the Changxing Science and Technology Industrial Park Station in Guangming District, Shenzhen City, Guangdong Province, and has performed well in all aspects.

As the company's first independently developed ultra-quiet liquid-cooled charger, it marks another major breakthrough in the company's intelligent charging technology and a milestone in the company's independent research and development history.

1. Five core advantages of ultra-quiet liquid-cooled chargers:

As the "heart" of infrastructure, the performance of the charger directly affects user experience and industry efficiency. As the first completely independently developed ultra-quiet liquid-cooled charging equipment, this product takes efficient heat dissipation, extreme silence, stability and reliability as its core advantages, bringing users smarter and safer charging solutions, and helping the new energy industry move towards higher standards.

Advantage 1: 20% efficiency improvement, charging one step faster

The ultra-quiet liquid-cooled charger precisely controls the temperature through circulating coolant, allowing the charger to maintain efficient heat dissipation even when running at full load, and the overall efficiency is improved by more than 20%.

Advantage 2: 0dB silent operation, creating a senseless charging scene

The cooling fan noise of traditional chargers can reach more than 60dB, which causes great noise pollution, while the liquid-cooled charger completely cancels the fan design, uses the liquid cooling circulation system to achieve "silent heat dissipation", and reduces the noise to 0dB. Whether it is charging late at night or deployed in high-end commercial areas, it can achieve the ultimate experience of "charging without disturbance".

Advantage 3: 10 years of maintenance-free, worry-free and money-saving

The liquid-cooled charger adopts a fully enclosed structure and corrosion-resistant materials, with no mechanical wear parts inside, and the coolant has long-term stability, and no maintenance is required within 10 years.

‌Advantage 4: IP68 protection level, no fear of extreme environments

The liquid-cooled charger achieves IP68 protection level (the highest level of dust and water resistance) through the integrated sealing design and multi-layer protection process, and can operate stably in an environment of -30℃ to 50℃. Whether it is in coastal high-humidity areas, northwest windy sand belts, or northeastern cold areas, it can guarantee charging services all year round.

‌Advantage 5: Five-layer safety protection, industry-leading safety level

Safety is the lifeline of charging equipment. The liquid-cooled charger builds a protection system from five dimensions: electrical safety, structural safety, thermal safety, data safety, and emergency safety:

5.1, Electrical safety: Real-time monitoring of voltage, current, and leakage, cutting off abnormal circuits within 0.1 seconds;

5.2, Thermal safety: The liquid cooling system accurately controls temperature to eliminate the risk of battery overheating;

5.3, Structural safety: Explosion-proof design + flame-retardant materials, non-flammable and non-explosive in extreme cases;

5.4, Data security: Encrypted communication + firewall to resist network attacks;

5.5, Emergency safety: Built-in fault self-check module, remote one-click lock risk.

2. Application scenarios:

2.1, Residential areas, schools, hospitals

The ultra-quiet liquid-cooled charging technology replaces the traditional fan cooling system and has lower noise, making it more suitable for use in noise-sensitive areas such as residential areas, schools, and hospitals.

2.2, Gas stations

The liquid-cooled charging module has stronger insulation, eliminates fire hazards, is safer, and has a higher level of protection.

2.3. Dust, high cold, high humidity, high altitude, etc.

Fearless of extreme environments, suitable for all scenarios such as dust and high altitude, it can operate stably in an environment of -30℃ to 50℃, and has extremely high protection performance.

2.4. Heavy truck charging station

Immersed liquid cooling technology can accurately control the temperature through circulating coolant, achieve efficient heat dissipation, extend the service life of the product, have high stability, and be easy to maintain.

3. Continuous innovation, leading the future

The ultra-quiet liquid-cooled charger is not only a product, but also a commitment of Hongjiali to future green travel. It redefines the possibility of charging new energy vehicles with innovative oil-immersed liquid cooling technology, excellent performance and considerate user experience.

In the future, we will continue to deepen the new energy field and use smarter and more reliable charging solutions to help green travel!
