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)​
