2 Functional Features

2.1 Basic Functions

Supports multiple battery types including lithium-ion, nickel-metal hydride, and lead-acid batteries, compatible with common electric vehicle models.
Intuitive full touchscreen HMI with clear status indication for easy operation and real-time working status monitoring.
Integrates multiple intelligent modules: authentication, metering & billing, background communication, and EV communication.

2.2 Safety Protection Functions

Built-in emergency stop switch for immediate power cutoff in critical situations.
Real-time communication with the vehicle BMS to monitor traction battery status, providing reliable protection against overcharge, over-temperature, and reverse polarity.
Clear visual and text prompts to effectively prevent operator misoperation.
Interlock safety mechanism: charging starts only after a valid connection is confirmed. If an abnormal connection is detected, the charger stops charging, disconnects the DC output, and unlocks the electronic lock to ensure safe separation between vehicle and charger.

2.3 Metering & Billing Functions

Supports time-of-use billing with automatic internal calculation for fee settlement.
Provides flexible payment methods including charging cards and QR code scanning. Charging card functions are restricted to management and maintenance personnel for equipment operation and temporary startup.

2.4 Communication Functions

Real-time communication with vehicle BMS to verify connection status and obtain charging parameters and real-time operation data.
Two-way communication with upper-level monitoring platforms to upload energy, billing, and IC card information, and support remote control and management.

2.5 Historical Data Recording

Power-off data retention function prevents charging data loss during unexpected power outages.
Automatically records recent events:
Alarm events (name and start time)
Parameter setting changes and charging records (name and start time)
