2 Core Features

2.1 Basic Functions

Multi-Battery Compatibility: Supports lithium-ion, nickel-metal hydride, and lead-acid batteries, compatible with most common EV models.
Intuitive Operation: Full touchscreen HMI with convenient operation and clear status indication.
Integrated Capabilities: Combines card encryption, metering & billing, backend communication, and EV communication functions.

2.2 Safety Protection

Comprehensive Safety Mechanisms: Full electrical protection suite, with automatic fault detection and alarm.
Emergency & Interlock Safety: Equipped with an emergency stop switch for immediate power cutoff; charging only starts after secure connection to the vehicle’s traction battery system, with automatic stop and lock release if abnormal connection is detected.
BMS Real-Time Monitoring: Communicates with vehicle BMS to prevent overcharge, over-temperature, and reverse polarity, ensuring battery and vehicle safety.
Misoperation Prevention: Clear status indicators and text prompts to avoid operator errors.

2.3 Metering & Billing

Accurate Energy Measurement: Built-in DC energy meter for precise charging power calculation.
Flexible Billing: Supports time-of-use electricity pricing for automatic fee settlement.
Payment Methods: Offers settlement via charging cards and QR code scanning; card operations are restricted to management and O&M personnel (not for customer use).

2.4 Communication

BMS Communication: Verifies connection status and retrieves charging parameters and real-time data from the vehicle’s battery system.
Remote Monitoring: Two-way communication with upper-level systems to upload energy, fee, and IC card data, and accept remote control commands.

2.5 Historical Data Recording

Power-Off Data Protection: Prevents charging data loss during accidental power outages.
Event Logging: Records the most recent alarm events, parameter modification events, and charging events (name + start time).
