EV Controller, Motor and Throttle Testing Device

The Controller Testing Device is a specialized diagnostic and troubleshooting tool engineered to quickly test, verify, and diagnose electric scooter speed controllers, BLDC motor systems, and electronic components. Built for technicians, repair service centers, and DIY enthusiasts, this device provides real-time fault detection to eliminate guesswork during EV maintenance and repair.

With direct support for 24V through 72V DC systems, it allows instant testing of throttle signal voltage, motor phase outputs, Hall sensor health, and main controller power delivery through clear, real-time LED indicators.

Key Features

• Multi-Function Real-Time Testing: Instantly diagnoses throttle signals, motor phase outputs, Hall sensors, and controller power delivery.
• Universal Voltage Support: Compatible with 24V, 36V, 48V, 60V, and 72V DC electric scooter and e-bike systems.
• BLDC & Brushed Motor Compatibility: Works with both brushless (BLDC) and brushed motor controllers across various EV models.
• Clear LED Indicator Panel: Features onboard LED status lights that give instant visual feedback on component health and electrical faults.
• Compact & Portable: Lightweight, durable plastic housing equipped with insulated test leads for workshop or mobile field service use.
• Plug-and-Test Connectivity: Connects directly into standard controller wiring ports for fast and accurate fault isolation.

1. Safety & Power Isolation: Turn off the electric vehicle's ignition switch and disconnect the main battery pack from the controller or wiring harness before handling test leads to prevent short circuits.

2. Connect Controller Power & Throttle Test Lines: Plug the tester's power output and throttle interface leads directly into the corresponding controller connector ports.

3. Test Motor Phase & Hall Sensors: Connect the 3 motor phase leads (Yellow, Green, Blue) and the 5-pin Hall sensor harness to the testing device terminals. Slowly rotate the motor wheel by hand.

4. Verify Throttle Signal Output: Twist the throttle slowly while observing the signal diagnostic lights on the device.

Keep the device clean by wiping the casing with a dry or slightly damp cloth, avoiding high-pressure water or harsh chemical cleaners. Inspect the test leads and connectors regularly for loose pins, frayed insulation, or signs of wear, and store the unit in a dry, cool place away from moisture when not in use.
