Why does the three wheeled electric vehicle show that it does not go when there is electric accelera

1. The reason for braking, electric tricycles have handbrakes, and of course the car will not go when the handbrake is pulled. In addition, most of the three wheels have a brake power-off function, once the car's brakes are faulty, such as the brakes do not return, the brakes do not work, and the car does not supply power.

2. The reason for turning the handle, use a multimeter to detect the voltage between the two wires of the lower handlebar, and then turn the handlebar, if the voltage of the red line and the black line has not changed, then measure the black line and the signal line. Finally, turn the handlebar, if the voltage changes from the change you can judge that the handle is normal.

3. The reason for the motor, the black needle of the multimeter is connected to the negative line of the hall, and the voltage of the corresponding line of the three halls of the motor is detected with a red pen, and the motor wheel needs to be gently rotated when measuring the three hall wires to see if the voltage of the multimeter has a voltage change of 0-5 volts. If there is no change, it means that the corresponding Hall element is faulty or the Hall wire is broken and replaced, otherwise, the Hall element is normal.

4. Check whether the battery output of the electric tricycle is normal, if the output is too low, it proves that the battery is bad, and the battery needs to be replaced urgently.

The causes and solutions are as follows:

It may be that the electric frequency is broken there, showing that there is electricity, but ** is not on the top of the car, and this needs to be repaired to deal with the electric frequency.

Check if the battery output of the electric vehicle is normal. If the output is too low, the battery is broken. The battery needs to be replaced urgently.

Pull the brake cord out of the section. If the car rotates, it proves that the kill handle is broken, and the kill handle must be replaced or repaired, and the kill handle is passed with Table 2 and the tube measuring kill handle.

Or the reason for the turn, use a multimeter to detect the voltage between the two wires of the lower handlebar, and then turn the handlebar, if the voltage of the red line and the black line has not changed, then measure the black wire and the signal line. Finally, turn the handlebar, if the voltage changes from the change you can judge that the handle is normal.

If you still can't find the problem after all the above reasons, it is recommended to find a professional to deal with it.

Hello, the reasons for the failure of the three gears of the electric car: 1. The transmission gear of the control and ambush Zheng system is not working, and the default medium speed, so you can see if you have taken it. See if there is a disconnection.

There is also the line speed of the controller, which is also a speed, which is relatively slow. 2. When the electric vehicle has a brush gear and no output: set the multimeter at the +20 engine (DC) gear, and first measure the high and low potential of the output signal of the brake handlebar.

If the potential change of the brake signal exceeds 4V when pinching the brake handle, the brake handle fault can be ruled out. Then, according to the commonly used Shidao upper foot function table of the brushed gear, the circuit analysis is carried out with the voltage value of the main control Shidaomin logic chip, and the value of the peripheral devices (resistors, capacitors, diodes) of each chip is consistent with the identification on the surface of the component. Finally, check that the peripheral device or integrated circuit is faulty, and we can eliminate the fault by replacing the device of the same model.

Summary. Hello, I am your exclusive technician, attentive, careful, dedicated to answering your car questions, for you to find the corresponding problem solutions and solutions, will provide you with a satisfactory answer! I hope this service can help you, if it is helpful to you, I look forward to your praise and attention.

There are many reasons for this situation, and the first one is the problem of the motor. Because the motor has the most direct impact on the power of the electric tricycle, if it has been aged, then the motor will be demagnetized. Once the motor is demagnetized, it will be weak when driving the electric tricycle, and the most direct manifestation is that the power is insufficient, and it can't run fast or far.

For this situation, generally speaking, the effect of repairing the motor is not very effective, and you can only choose to replace the new motor to solve the problem of insufficient power of the electric tricycle The second is the problem of the battery. If the battery has been aging and charging, then if you charge the electric tricycle at this time, although it seems that the tricycle has been fully charged on the surface, the actual charging effect is only less than 50%, and the power of the tricycle is still insufficient. In this case, generally speaking, the problem of insufficient power of the electric tricycle can only be solved by replacing the new battery.

The third is the controller. I hope my answer is helpful!!

Summary. Hello, how to solve the problem that the electric tricycle can't run fast, replace the high-power motor, controller, and battery (the battery car electrical appliances are all replaced in the three major parts, which is equivalent to buying a new car). Scheme 2, overpressure, principle introduction:

1. Overpressure a battery, the theoretical speed increases by 10km h, and the actual speed increases by about 8km h. 2. The speed is increased by 1 time, which is equivalent to the power increased by 7 times5c2 is the electric vehicle discharge rate rule.

For example: 60V20AH battery, 800W motor, add a battery speed added value calculation, output power is 800W, the speed of the car is about 40 km h, add a battery, the theoretical speed is about 50km h, 2, the speed increase = 10 40, equivalent to the power increase multiple = 7 4 = times, that is, the motor is equivalent to 800 *, 3, the battery capacity = 1400 * 2 72> = 39Ah, choose at least 40Ah battery. 4. The choice of charger is consistent with that of the battery.

The charger selection is consistent with this nuclear power bottle. 5. The controller selects a rated voltage of 72V or above, and a power of 1400W or above.

It's not fast to change a knob at the car repair station.

Summary. Hello, I am happy to answer your car master exclusive technician to answer your car questions sincerely and sincerely for you, and find solutions and methods for you to ask questions. The electric tricycle is slow and weak, so check whether the battery level is too low.

This happens even after the battery is fully charged. Lift the wheels up first and try to see if the idling speed is sufficient. If there is no problem with idling, the controller is good, and it may be caused by a short circuit between the brakes in the internal coil of the motor.

Check the connection line of the motor, there is no false connection, just repair or replace the motor. Hope I can help you.

The electric tricycle is slow and weak, the problem is **?

Dear, this question is up to me, it takes a little time to type, please be patient, thank you!

My tricycle was driving this morning and suddenly weakened, and when accelerating I could hear the motor turning and there was a bit of force, but I found that the wire box would smoke after accelerating too long, but it was okay to go slowly, and it was broken there.

In this case, it is very likely that the internal coil of the motor has been short-circuited. Check the connection line of the motor, and if it is normal, just repair and replace the motor.

In the past, I found that the insulating glue of the three large wires of the motor connection line was damaged, and it is possible that they are now stuck together and cause a short circuit.

This is possible, and it must be dealt with as soon as possible, otherwise it will cause the controller to burn out.

The smell of burning and smoking is burning there.

Broken circuits, short circuits, overheating, or smells from the coils inside the motor.

I found out that it was the wire box that came out of there.

This is due to excessive current. The wire box can't withstand the overheating and smoke caused by such a high current.

Hasn't the wire box burned out yet?

This needs to be opened and checked.,How hot is it.,How much is the smoke.,It's fine if it's slight.。 It's fine to return the current to normal. If the current is too high, it will also cause the line to heat up.

I think the motor is still good, it's not broken, it's just that the connecting line is broken, and the three main lines are stuck together, so it's okay to replace the connecting wire.

Yes, in this case, if you replace the cable or find that the damage to the cable is not serious, you can separate the cable and re-wrap it with insulating tape. Dispose of the connector of the connecting wire, otherwise it will still burn out if there is a false connection.

If I can help you, please give me a thumbs up Thank you!
