2 Functional Features​

2.1 Basic Functions​

Supports charging for lithium-ion, nickel-metal hydride, and lead-acid batteries, compatible with most common EV models.​
Full touchscreen HMI for convenient, fast operation; top-mounted status indicators enable easy real-time monitoring of operating status.​
Integrates card encryption, metering & billing, background communication, and EV communication functions.​

2.2 Safety Protection Functions​

Equipped with an emergency stop switch: Quickly cuts off power and stops charging in emergencies.​
Real-time communication with the vehicle BMS to monitor traction battery status; instantly stops charging upon fault alarms (overcharge, over-temperature, reverse polarity) to protect vehicle equipment and batteries.​
Clear status indicators and text prompts to prevent operator misoperation.​
Interlock safety mechanism: Charging initiates only after correct connection to the vehicle’s traction battery system. Detects abnormal connections during charging, automatically stops charging, disconnects the DC output circuit, and unlocks the electronic lock to ensure safe separation.​

2.3 Metering & Billing Functions​

Supports time-of-use electricity input for automatic billing conversion and charging fee settlement.​
Offers consumption settlement via charging cards and QR code scanning. Card swiping is restricted to management and O&M personnel for facility maintenance and temporary activation (not issued to customers).​

2.4 Communication Functions​

Communicates with the vehicle’s BMS to verify connection status and obtain charging parameters and real-time data.​
Two-way communication with upper-level monitoring systems: Uploads power, fee, and IC card information to remote monitoring, while accepting remote control commands.​

2.5 Historical Data Recording Functions​

Power-off data retention function prevents charging data loss due to accidental power outages.​
Records the most recent events:​
Alarm events (name + start time)​
Parameter modification and charging events (name + start time)​

FAQ

Q1: How fast can a 120kW–240kW charger charge an electric vehicle?

A: These are “Ultra-Fast” chargers designed for maximum efficiency. A 240kW unit can theoretically add about 200–300 km of range in just 10–15 minutes for compatible vehicles. Even a standard 60kWh battery can be charged from 10% to 80% in under 20 minutes, making this range perfect for sites where drivers are in a hurry.

Q2: Can these chargers handle two vehicles at the same time?

A: Yes. These units typically feature Dual-Gun (Dual-Connector) outputs. The system uses intelligent power distribution to manage both sessions simultaneously. For example, a 240kW charger can provide 120kW to two cars at once, or dynamically allocate more power to the car with a lower state of charge.

Q3: Is it compatible with the new 800V luxury EV platforms?

A: Absolutely. This series features an ultra-wide output voltage range of 150V to 1000V DC. This ensures full compatibility with both traditional 400V battery systems and the latest high-voltage 800V platforms (like those from Porsche, Hyundai, and Kia), allowing them to charge at their maximum rated speeds.

Q4: What are the best locations for installing 120kW–240kW chargers?

A: Due to their high power and rapid turnover, these chargers are best suited for:

• Highway Service Stations: Where long-distance travelers need a quick “splash and dash.”

• Electric Bus & Truck Depots: For heavy-duty vehicles with large battery capacities.

• Commercial Hubs & Fleet Centers: For ride-hailing (Uber/Taxi) fleets that need to stay on the road.

• Public Super-Charging Stations: In high-traffic urban areas.

Q5: What international standards do these chargers support?

A: These units are designed for global markets and can be configured with multiple connector types:

• CCS2 / CCS1 (European and North American standards)

• GB/T (Chinese National Standard)

• NACS (Tesla/North American Standard)

• CHAdeMO (Japanese standard)

Q6: What are the power supply requirements for installation?

A: These are high-demand industrial machines. They require a robust Three-Phase AC 400V (±10%) or 480V connection. Given the high wattage, a dedicated transformer or a significant grid capacity upgrade is usually required at the installation site.

Q7: How do I manage the charger remotely?

A: The charger is fully integrated with OCPP 1.6J (upgradable to 2.0.1). This allows operators to:

• Monitor real-time charging status and power usage.

• Manage billing and user authorization.

• Perform remote diagnostics and Over-The-Air (OTA) software updates via 4G, Ethernet, or Wi-Fi.

Q8: What safety features are included for such high power?

A: High power requires high-level safety. The unit includes:

• Comprehensive Protection: Over/under voltage, overcurrent, short circuit, and surge protection.

• Thermal Management: Intelligent cooling systems and temperature sensors to prevent overheating.

• Physical Safety: An IP54/IP55 weather-resistant enclosure and a heavy-duty Emergency Stop button.

• Insulation Monitoring: Constant checking for ground faults or leakage to ensure user safety.

Q9: How do users interact with the charger and pay?

A: The charger features a premium 7-inch or 10.1-inch high-brightness touchscreen that works in direct sunlight. Payment and activation are seamless via:

• RFID Cards: For fleet or subscription users.

• Mobile App/QR Code: For ad-hoc public users.

• Optional Credit Card Terminals: Supporting “Tap & Go” payments for maximum convenience.
