Water-cooled charging gun
Model No.:
The water-cooled charging gun is a high-power electric vehicle charging device utilizing liquid circulation cooling technology. Coolant (water or specialized cooling oil) circulates through the cable and gun head to efficiently dissipate heat generated during charging, supporting currents of up to 500A–800A and compatible with 600kW ultra-fast charging systems. This enables rapid “1 kilometer per second” energy replenishment. Its core value lies in overcoming thermal limitations of high-power charging while enhancing efficiency and safety.

Features
Product Features and Advantages
① Performance Advantages & Technical Features
Efficient Heat Dissipation & High-Current Support:
A closed-loop liquid cooling system (physically isolated coolant and current circuits ) rapidly conducts heat away. Cables with a diameter of only 30mm stably deliver 600A–650A continuous current, achieving over 600kW charging power—3–5x more efficient than traditional air-cooled guns. Enables 20%–80% charge replenishment in under 10 minutes.
Multi-layer Safety Protections:
IP67-rated housing for waterproof/dustproof performance; integrated temperature, coolant leakage, and orientation sensors with smart MCU for real-time anomaly detection and overcurrent/overvoltage/short-circuit protection; complete electrical isolation of coolant eliminates short-circuit fire risks.
Lightweight & Intelligent Design:
Liquid cooling reduces cable weight by over 50% for easier handling; supports CAN/Bluetooth/NFC communication for remote charging monitoring, fault diagnosis, and full lifecycle management.
② Application Scenarios
Urban Public Ultra-Fast Charging Stations: Covers 1–2 km radius charging demands, compatible with Tesla, XPeng, and other mainstream EVs, alleviating congestion in high-density areas.
Highway Service Areas: Enables rapid recharging for long-distance EVs, reducing stops to under 10 minutes and improving travel efficiency.
Commercial Fleet Hubs: Supports high-frequency, high-current charging for logistics centers and taxi fleets (e.g., Huolala delivery vehicles), minimizing operational downtime.
Future-Ready Compatibility: Adaptable for hydrogen/hybrid vehicles; 1000V wide-voltage range supports 800V high-voltage platforms for ultra-fast charging network expansion.
