Smart 400kW EV Charger with RFID/Mobile Pay Upgradable To OCPP 2.0 for Future-Proof Networks

ARK EF400CC400 400kW dual-gun DC Fast Charging Station - Redefining the benchmark for charging operation efficiency

Designed specifically for charging station operators, commercial real estate developers and enterprise fleets, it achieves efficient operation of the charging network and maximizes the return on investment (ROI) through three core advantages: improved equipment utilization, reduced operation and maintenance costs, and data-driven management.

⚡

1.The Efficiency revolution: Making every device create more value

Dual guns charge in parallel, increasing the equipment utilization rate by 100%

• Double service capacity: The dual CCS-2 guns support charging two electric vehicles simultaneously (each gun 200kW). During peak hours, the charging efficiency is directly doubled. Under the same site conditions, the number of vehicles served is increased to twice that of the traditional single-gun equipment.

• Dynamic power distribution: The intelligent algorithm automatically optimizes the power output of the dual guns, supporting flexible configuration (such as 400kW priority fast charging for a single gun or balanced distribution between the two guns), suitable for various scenarios such as high-frequency energy replenishment for taxis/ride-hailing vehicles and temporary charging for private cars.

• Measured data: After the deployment in a certain expressway service area, the average daily charging frequency of a single device increased from 8 times to 15 times, and the monthly revenue grew by 90%.

2. Intelligent remote management leads to a 50% reduction in operation and maintenance costs

• Full life cycle digitalization: Connect to the cloud management platform via the OCPP 1.6J protocol (supporting upgrade 2.0) to monitor the device status (voltage/current/temperature), charging orders, and energy consumption data in real time. The fault early warning response time has been shortened to 3 minutes.

• Remote operation and maintenance capability:Remote start and stop charging, adjustment of power parameters, no on-site intervention required;The OTA remote upgrade function enables the rapid deployment of new protocols (such as V2G support in the future) and security patches, reducing on-site labor costs.

• Offline emergency solution: Supports USB local data export. Even if the network is disconnected, charging records can still be obtained to ensure data integrity.

3. Modular design and intelligent maintenance reduce downtime by 80%

• Plug-and-play modular architecture: 10 independent 40kW charging modules. When a single module fails, the rest can still operate. The replacement time for a single module is less than 30 minutes (traditional equipment requires more than 4 hours of power-off and maintenance for the entire machine).

• Intelligent heat dissipation and cable management:The forced air cooling system automatically adjusts the fan speed, ensuring stable efficiency in high-temperature environments and reducing downtime caused by overheating. The balanced reel automatically stores the cables, avoiding damage caused by human dragging. The lifespan of  the cables is extended by 2 years, and the maintenance frequency is reduced from 3 times a month to 1 time.

Typical case: Cost Reduction Practice of a certain logistics park

•  Pain points: Traditional single-gun equipment has severe queuing for charging, a high equipment failure rate in winter, and operation and maintenance costs account for 35% of the total expenditure.

• Solution: Deploy 3 EF400CC400s and enable RFID fleet card authentication + remote power limiting (to prevent grid overload).

• Achievements:

◦ Improved charging efficiency: The average daily charging time for 30 logistics vehicles has been reduced by 40%, and the vehicle turnover rate has increased by 25%.

◦ Reduced operation and maintenance costs: The modular design has reduced the fault handling time by 70%, and the annual maintenance cost has dropped from 120,000 yuan to 50,000 yuan.

◦ Management efficiency improvement: Through the energy consumption report in the background, the charging period is optimized to the off-peak electricity range, and the monthly electricity bill is saved by 18%.

All-scenario efficiency fit to meet diverse operational needs

▶ Public charging station operator

• Core Value: The dual-gun design caters to high-traffic scenarios, and the OCPP protocol seamlessly integrates with third-party management platforms (such as ChargePoint and Plugsurfing) to rapidly expand the network scale.

• Efficiency Tool: Supports GPRS/LTE networking, allowing devices in remote areas to be online in real time. Combined with Nayax credit card terminals (covering over 25 countries), it enhances the efficiency of cross-border charging settlement.

▶ Commercial real estate (shopping centers/office buildings)

• Value-added logic: The charging area becomes the entry point for customer flow. The 10-inch touch screen supports brand advertising placement (optional). RFID membership charging is automatically associated with consumption points, increasing user dwell time and repurchase rate.

• Management advantages: The back-end data is connected to the property management system, and the status of the charging equipment is linked to the parking lot's traffic diversion strategy (such as full charge notifications being pushed to the owner's APP to guide them to leave and clear their space).

▶ Enterprise fleet/logistics park

• Key to cost reduction: RFID cards accurately lock the charging permission to prevent unauthorized use; Charging data is classified and statistically analyzed by vehicle/department, with clear allocation of energy consumption costs, facilitating the control of operational budgets.

• Environmental adaptation: Wide temperature operation range from -30°C to +55°C, no additional temperature control equipment required. Stable operation in high-temperature storage and severe cold in the north, reducing equipment idle losses.

Technology hard power: The underlying support for efficiency improvement

• High power density design: 400kW output power is integrated into a 2070×850×910mm body, reducing the floor space by 20% compared to traditional equipment of the same power and achieving a higher utilization rate of land resources.

• Grid-friendly features:

◦ Power factor 0.99 (rated output), reducing reactive power loss in the power grid and avoiding fines caused by harmonic pollution;

The three-phase input design is compatible with industrial power grids, supporting 400Vac±10% voltage fluctuations, and reducing equipment downtime caused by unstable voltage.

• Compliance and Safety Assurance: Certified by CE (DEKRA), IEC 61851-23, etc. Multiple protection mechanisms (overvoltage/leakage/lightning strike) ensure the reliable operation of the equipment 7×24 hours, avoiding operational disruptions caused by accidents.
