1. Introduction
This manual provides essential information for the safe and effective use of your Enpower MC3625 series electric vehicle controller. This controller is an original component designed for Jinpeng Taurus V8 D70 S70 electric vehicles, available in 60V (MC3625-6027) and 72V (MC3625-7227) variants. Please read this manual thoroughly before installation and operation.
2. Safety Precautions
- Always disconnect the battery power before installing, removing, or servicing the controller.
- Ensure all connections are secure and correctly polarized to prevent damage to the controller or vehicle.
- Avoid exposing the controller to water, excessive moisture, or extreme temperatures.
- Only qualified personnel should perform installation and maintenance to prevent electrical hazards.
- Do not attempt to open or modify the controller casing, as this will void any potential warranty and may cause malfunction.
3. Setup and Installation
The Enpower MC3625 series controller is designed for specific Jinpeng electric vehicle models. Proper installation is crucial for optimal performance and safety. It is highly recommended that installation be performed by a certified technician.
3.1 Compatibility Check
Before installation, verify that you have the correct controller model (MC3625-6027 for 60V systems or MC3625-7227 for 72V systems) for your Jinpeng Taurus V8 D70 S70 electric vehicle. Refer to your vehicle's original specifications or nameplate for confirmation.
3.2 Wiring Connections
The controller features various terminals and connectors for power, motor phases, and auxiliary functions. A typical installation involves connecting the following:
- Battery Power (B+, B-): Connect the main positive (B+) and negative (B-) terminals to your vehicle's battery pack. Ensure correct polarity.
- Motor Phase Wires (U, V, W): Connect these three terminals to the corresponding phase wires of your electric motor.
- Signal/Auxiliary Connectors: Multiple multi-pin connectors are provided for throttle input, brake signals, ignition, speed sensor, and other vehicle-specific functions. Consult your vehicle's wiring diagram for precise connections.

Ensure all connections are tight and insulated to prevent short circuits. After all connections are made, double-check your work before applying power.
4. Operating Instructions
Once the controller is correctly installed and connected, its operation is integrated with your electric vehicle's existing control system (e.g., throttle, ignition). The controller manages power delivery to the motor based on user input and vehicle conditions.
- Power On/Off: Use your vehicle's main ignition switch to power the controller on or off.
- Throttle Control: The controller interprets signals from the throttle to regulate motor speed and power output.
- Braking: Brake signals will instruct the controller to cut power to the motor and may activate regenerative braking if supported by your vehicle system.
Always operate your electric vehicle according to its manufacturer's guidelines and local traffic laws.
5. Maintenance
The Enpower MC3625 series controller is designed for durability and reliability. Minimal routine maintenance is required.
- Regular Inspection: Periodically inspect the controller and its wiring for any signs of damage, corrosion, or loose connections.
- Cleaning: Keep the controller free from dust and debris. Use a dry, soft cloth for cleaning. Do not use liquid cleaners or solvents.
- Ventilation: Ensure the area around the controller has adequate airflow to prevent overheating, especially during prolonged operation. The integrated heat sink fins (visible in Figure 3) are crucial for heat dissipation.

6. Troubleshooting
If you experience issues with your electric vehicle's power system, consider the following basic troubleshooting steps. For complex problems, consult a professional technician.
- No Power: Check battery connections, vehicle ignition switch, and main fuses. Ensure the battery is adequately charged.
- Motor Not Responding: Verify throttle connections and functionality. Check motor phase wire connections (U, V, W) for looseness or damage.
- Intermittent Operation: Inspect all wiring for loose connections, frayed wires, or signs of corrosion.
- Overheating: Ensure the controller is not obstructed and has sufficient airflow. Reduce heavy load operation if overheating persists.
If the problem persists after basic checks, it may indicate an internal fault with the controller or another component of your vehicle. Professional diagnosis is recommended.
