Electric tricycle common six troubleshooting methods

First, the vehicle has no electricity, how to check?

First check whether the power supply is electricity, if not, check whether the fuse is intact, if the fuse is normal, the power supply is no power, check whether the internal electrode connection of the power supply is loose, and whether the battery is disconnected. If the power supply is active, check whether the power cable and power lock are normal.

Second, the whole vehicle has electricity, the motor does not turn how to check?

If the motor is running normally, the motor and the controller are good, if the motor does not turn, the motor is bad or the controller is bad if the motor and the controller are normal, the motor does not turn, it may be a problem with the brake handle.

Third, how to detect brushless motor?

1, the motor all and harness plug unplug, use the multimeter diode file, the multimeter red needle refers to the motor six-core plug on the thin red line, black needle refers to the thin yellow, blue, green and black lines, the value is displayed as more than 900, the red needle refers to the black line, black needle refers to the thin yellow, blue, green and red line, the value is displayed as 500 ~ 600. Displays 0 or infinity are bad.

2, in the power state, with the 200V DC voltage of the multimeter, the black needle refers to the thin black line of the six-pin plug, the red needle refers to the thin yellow, blue, green line, rotate the motor, and the voltage display changes between 0V and 6.25V. The maximum and minimum values of the three lines should not differ much.

Four, how to detect the handle?

Use the multimeter to measure the nine-pin plug of the controller with 20 volt voltage, black pen on the thin black line, red pen on the thin yellow line, at this time the voltage should be about 1V, turn the handle to the end, the multimeter shows 1V to 4.2V or 4.8V, then the handle is good.

Five, how to detect the brake handle?

Use a multimeter 20-volt voltage file to measure the nine-core plug of the controller, the black pen refers to the thin black line, the red pen refers to the fine purple line, the voltage is displayed as about 6V, is zero, the brake is often powered off, hold the brake handle, at this time the multimeter should be displayed as 0, the voltage is unchanged, the brake handle is constantly powered.

Six, how to detect brushless controller?

1, power tube damage detection: power tube bad performance as the vehicle does not turn or lack of phase, the specific measurement method is: Use diode to test the controller a, b, c three-phase motor wiring, the black pen of the multimeter is connected to the power supply red line, the red pen is connected to the three-phase motor phase line, the display value of the multimeter should be about 500 ~ 600, if the test result of a phase is zero or very small, then the phase of the upper power tube breakdown, if the display is very large for the break; The red pen of the multimeter is connected to the power supply ground wire, and the black pen is connected to the three-phase motor phase line. The display value of the multimeter should be about 500 ~ 600. If the display is zero or very small, the lower power tube of the phase is broken down.

2, in the case of power on, use the multimeter voltage file to measure the controller nine-core plug.
