4. The average efficiency of the charger is about 70%, and it needs 130% of the battery to be fully charged.

How to deal with electric tricycles without electricity

Regardless of whether the tricycle is energized or not, the driving force should be supported for repair and detection. The tricycle is generally powerful. If it runs automatically, it can't be controlled and it is easy to accident!

1, the cause of the hand brake. Electric tricycles have handbrakes. Pulling the handbrakes does not leave the car and does not leave the car to implement the effort. Because the brakes have brakes, the brakes are not returned, and the car does not go!

2, the reason for turning. Generally, the electric tricycle handle has five lines, red line, black line, blue line is the turn line, and the other two are the reverse line. Use a multimeter to detect the voltage between the two lines, turn the turn, red line black If the line voltage has not changed, the black line and the signal line are measured. When the voltage is turned, the voltage follows the change of the speed voltage from 0.8-4.2. It can be judged that the turn is normal, and the turn is broken! There is also a faster way, from the controller to export the line to find the turn line with the turn to try it, directly connected to the turn, indicating that the turn may be broken, go to the front of the switch plug directly to use the turn If you are sure that the switch is broken, if you do not turn the middle turn, there is a break, please replace it. If you do not go directly on the controller, please do the next test! Check the handle, short-circuit the wire with the positive pole and the signal line (saying that the switch is short-circuited). If the car turns to prove that the switch is broken, it is urgent to replace or repair it. Turn on the power and turn the turn to use the universal meter positive line and Signal line.

3. The reason of the motor. The motor usually has a high probability of Hall damage. If the Hall is broken, the controller is not smart or it may not be energized or the work is "trembling". The specific detection method: determine the phase line of the motor and the Hall line and the controller are well connected, and open the power lock. Power on the controller, adjust the multimeter to DC +20 volt position, connect the black hand of the multimeter to the negative line of the Hall, and use the red pen to detect the voltage of the three Hall corresponding lines of the motor. When the Hall line is needed, you need to gently turn the motor wheel to see if the voltage of the multimeter has a voltage change of 0-5 volts. If there is any change, it means that the corresponding Hall element is faulty or the Hall line is open, replace, otherwise the Hall element normal. It is also possible to measure the resistance value of the motor to determine the specific method: use the multimeter to measure the resistance value to measure, remove the motor Hall line from the controller, insert the red pen into the Hall positive red line, and the black pen sequentially detects the yellow line, green Line, blue line to see the resistance, normal three-phase motor has internal resistance, the difference between the three-phase resistance is relatively small, indicating that the motor is normal, if the difference is large or there is no resistance between the motor, the motor is broken, or the motor line is broken! Hall yellow, blue, green which phase is not normal, indicating that the corresponding Hall is broken or the Hall line is broken! The Hall in the middle is broken. It should be noted that when the Hall is facing up or up, face down or down, there is a phase angle problem, which is divided into 60 degrees and 120 degrees. The wrong controller is not installed. Intelligent will work abnormally! Check the motor is good or bad, the motor carbon brush contact is not true will also cause electricity to go.

4. Controller reasons. Use a multimeter to adjust to the DC 200v gear position, check whether the power supply of the power cord is normal, and ensure that the power cable and the power lock cable are energized, and the controller output line is measured. If there is no output voltage, the control is broken! Some internal components of the controller will cause the rotation to move without any effort. Unplug the motor's phase line "thick line". If the motor becomes dexterous, the controller is broken! General electric vehicle tricycle power large current in the installation of the controller must pay attention to, in order to safety, let the power line, motor line, turn the line must be in contact with the actual, otherwise the contact will cause the line burnt is self-igniting danger! It is best not to use the connector to connect the switch directly, in case the water is easy to fly in the case that the controller does not have anti-flying protection, it can not control, triggering danger! In addition, the electric tricycle should have all functions, such as: high and low brake power off, reversing function, high and low speed function, please also use the user correctly, often maintenance, diligent care, find glitch timely repair, not because of minor faults Cause big problems and unsafe, do not overload, run laborious, parts are easy to damage, affect the life, and also control the speed when turning, do not make sharp turns, to prevent rollover! Whether the controller is good or bad can be shorted by the positive 5V of the turning wire. If the turning handle rotates, it means that the controller is no problem. The easiest way to smell the controller is to burn the taste. If so, the controller is broken. .

5. Check if the battery output of the electric vehicle is normal. If the output is too low, it proves that the battery is bad and it is urgent to replace the battery.

6. Pull off the brake line. If the car turns, it proves that the brake is broken and the brake must be replaced.
