The VanTon 20kw CCS Gbt Connector DC Portable EV Fast Charger converts household or commercial AC directly to DC, bypassing the car’s onboard charger. With a 4.3‑inch touchscreen, OCPP connectivity, and interchangeable CCS/GB/T plugs, it turns any accessible power point into a fast‑charging station – ideal for fleets, workshops, roadside rescue, and temporary events, with zero installation required.
Key Advantages
Lightweight and mobile
This 20kw CCS Gbt Connector DC Portable EV Fast Charger weighs under 40 kg and includes built‑in wheels and a telescopic handle, allowing one person to move it effortlessly between locations.
Quick charging capability
20 kW output is ideal for rapid top‑ups during short breaks, adding significant range in 30‑60 minutes for most passenger EVs.
Wide voltage compatibility
The output range of 200‑1000 V DC supports both 400‑V and 800‑V battery systems, covering the latest EV models including those with high‑voltage platforms.
Simple installation
no fixed mounting required; just connect to a suitable AC supply (single‑phase 220 V at 32 A or three‑phase 380 V at 16 A) and start charging.
Smart connectivity
Integrated 4G, Wi‑Fi, and Ethernet with OCPP 1.6/2.0 enable remote monitoring, billing integration, and firmware updates, making the 20kw CCS Gbt Connector DC Portable EV Fast Charger suitable for commercial networks.
Robust protection
IP54 enclosure, overvoltage, undervoltage, overcurrent, short‑circuit, leakage, grounding, and over‑temperature protections ensure safe operation in diverse environments.
Application Scenarios
Logistics and ride‑hailing fleets: drivers can quickly recharge during meal breaks or between trips, maximising vehicle uptime and operational efficiency.
Automotive dealerships and repair workshops: the portable unit allows fast pre‑delivery charging or battery testing without occupying a dedicated service bay.
Roadside emergency and rescue: as a mobile power station, it can revive stranded EVs with a depleted battery, providing enough range to reach the nearest fixed charger.
Temporary events and exhibitions: set up a short‑term charging point for electric vehicles at trade shows, outdoor festivals, or construction sites with minimal infrastructure.
Remote locations: where fixed charging infrastructure is unavailable, this charger brings fast DC capability to rural areas, mining sites, or temporary work camps.
Safety & Maintenance
1. Input cable temperature: under continuous 32 A load, the AC input cable heats up; use a 6 mm² or larger national standard cable and regularly inspect terminal connections for tightness.
2. Grounding reliability: the 20kw CCS Gbt Connector DC Portable EV Fast Charger demands a solid earth connection; poor grounding can cause leakage protection trips or charging errors.
3. Rain and dust protection: although rated IP54, avoid using in heavy rain; operate under a canopy or in dry conditions to prolong component life.
4. Regular dust cleaning: the forced‑air cooling system accumulates dust on heatsinks and fans; disconnect power and clean the interior every 3 months to maintain thermal performance.
5. Periodic functional checks: test the emergency stop button, insulation monitoring, and communication ports monthly to ensure all safety features are operational.
Troubleshooting
Input voltage anomaly
If the screen shows "input voltage abnormal", check for phase loss or voltage imbalance on the three‑phase supply (should be 380 V ±15 %). Use a multimeter to verify each phase; if missing, inspect the distribution box and circuit breakers.
Sudden circuit breaker trip
This often indicates insufficient input breaker capacity (recommend 40 A or higher) or overloaded wiring. Consider replacing with a D‑curve breaker that handles inrush currents better.
Output power below 20 kW
First confirm the vehicle BMS request limit; then check if the input voltage is below 340 V (which triggers derating). Also note that high ambient temperature (>50 °C) will cause automatic power reduction to protect the unit; power recovers after cooling.
Communication failure with OCPP:
Verify network connectivity (4G/Ethernet) and that the backend server URL and port settings are correct. Restart the unit and check the firewall settings if using a corporate network.
FAQ
Q: Does the 20kw CCS Gbt Connector DC Portable EV Fast Charger support 800‑V vehicles like the Porsche Taycan or NIO ET7?
A: Yes, the unit outputs up to 1000 V DC, covering both 400‑V and 800‑V platforms. However, confirm that your specific vehicle’s DC inlet is compatible with the connector type (CCS or GB/T) and that the BMS requests voltage within the range.
Q: What are the AC supply requirements?
A: The charger accepts single‑phase 220 V at 32 A or three‑phase 380 V at 16 A. A dedicated circuit with a 40‑A breaker and 6 mm² copper cable is recommended for safe, full‑power operation.
Q: How long does it take to charge a typical 60‑kWh EV battery?
A: At 20 kW, it adds about 100‑120 km of range per hour. A full charge from empty would take approximately 3 hours, but most commercial users only need a 20‑30 minute top‑up during breaks.
