Flexible Interfaces for EV Charging System Integration
The EV charger control board provides multiple interfaces for connecting different components of a DC charging system.
Communication Interfaces
CAN | isolated CAN 2.0 | non-isolated CAN | RS485 | RS232 | Ethernet | Optional 4G / Wi-Fi | USB Type-A | LVDS | System Interfaces
The controller also supports
channel voltage sampling | channel temperature sampling | channel insulation detection | channel CC1 detection | digital inputs | digital outputs
These interfaces allow the controller to connect with charging modules, BMS, meters, displays, fans and safety devices.
Independent Control for Two Charging Guns
Designed as a dual-gun DC charging controller, the THCDKZQ-D2-WT supports independent communication and monitoring for Gun A and Gun B.
For each charging gun, the controller supports:
- BMS CAN communication
- Electronic lock control
- Contactor and discharge control
- Charging status feedback
- Voltage sampling
- CC1 detection
- Positive and negative electrode temperature monitoring
This enables coordinated control and real-time status monitoring for dual-gun DC charging equipment.
Integrated Safety & Status Monitoring
The DC fast charger controller supports multiple inputs and outputs for monitoring charging system status and safety conditions.
Safety Monitoring
The controller can monitor devices and signals including:
Emergency stop | Access control | Smoke detection | Water immersion detection | Tilt detection
Lightning arrester | Incoming circuit breaker | Contactor status | Fan status
Lightning arrester | Incoming circuit breaker | Contactor status | Fan status
Charging Status Detection
The controller also supports:
Voltage sampling | Temperature sampling | Insulation detection | CC1 detection | Charging gun status feedback
These functions help the charging system monitor operating conditions and respond to different system states.
Flexible Fan Control
The THCDKZQ-D2-WT supports both fixed-speed and variable-speed fan control.
For variable-speed control, the controller uses a 0–5 VDC PWM signal with a 30–100% duty cycle.
Fan speed can be adjusted according to the overall system output power and collected temperature data.
This provides flexible thermal management for DC charging equipment.
