The electric car is driving one meal at a time, what s going on?

1. There is a virtual connection between the positive and negative solder joints of the power lock, which causes the electric vehicle to stop and go.

When there is a situation where the electric vehicle appears to stop and go, after checking that the motor and battery are normal, it is likely that the positive and negative solder joints of the power lock are falsely connected, and this will lead to the electric vehicle will have power and no power for a while, and there will be a situation of stopping when going and stopping. How to solve it? For electric vehicle users, it is necessary to send the electric vehicle to the repair shop, and reconnecting it can solve the problem of the electric vehicle when it is stopped and go.

Second, the motor hall failure, resulting in the electric vehicle to stop and go.

Many electric vehicle users do not pay attention to the maintenance of electric vehicles in the daily use process, resulting in Hall failure of the motor. This will directly cause the motor speed to be unstable, or even not to rotate, resulting in the electric vehicle will have power, and there will be no power, and there will be a situation of going and stopping. How to solve it?

In many cases, some electric vehicle masters require users to directly replace the motor, in fact, the most reasonable way is to directly replace the Hall, which can solve the problem of electric vehicles when going and stopping.

3. The abnormal speed regulation and turning handle cause the electric vehicle to stop when it goes and stops.

If there is an abnormal situation in the speed control handle of the electric vehicle, then the acceleration of the electric vehicle will be unstable, the direct manifestation is that the power will suddenly fail in the normal driving state, and it can return to normal when it is started again, and this situation also belongs to the time to go and stop. How to solve it? Replacing the speed control handlebar can solve the problem of walking and stopping when the electric vehicle is stopped.

Fourth, the battery interface is loose or virtually connected, resulting in the electric vehicle going and stopping.

If the battery interface is loose, or there is a false connection, then the electric vehicle will also go and stop. How to solve it? For electric vehicle users, this kind of problem can generally be solved by connecting it by itself.

In short, the situation of electric vehicles when they stop is generally caused by these four reasons, for electric vehicle users, although it is not a big fault to stop when walking, but it will affect the safety of electric vehicles, if the power is suddenly cut off in the middle of the road, it is not good. Therefore, it is important to solve the problem as early as possible.

Hello, it is very likely that the motor of your electric car has failed, and here it is recommended that you go to a professional repair shop for repair to prevent traffic accidents.

The reasons for the start of the electric vehicle are loose motor wires or scorching; The battery is insufficient, or the battery wiring is loose somewhere, and there may be a broken battery; Poor contact of the handlebar; The retaining nut of the motor is loose.

The more serious situations are controller failure, motor hall failure, motor burning, and motor bearing failure. You first check whether the motor nut is tightened, whether the electricity is more or less, and whether the tire pressure is enough.

If you have tools, you can disassemble the bucket to see if the battery wire is about to break, the screws are loose, and look at the controller to see if the thick wire is burnt and loose. If it's not for the controller motor is broken, it's generally a problem here.

Precautions for the use of battery cars.

When the electric vehicle is not much electricity, it will also be a meal, which is the controller in order to protect the battery to set a minimum voltage value, that is, the undervoltage value, to prevent the battery from over-discharge. When the battery voltage drop changes greatly, when the electricity is less, the voltage is easy to fall off the undervoltage value, the controller stops output, and then the voltage will slowly rise, so repeatedly it causes a situation of one meal at a time, or walk and stop for a while.

In this case, please check whether the battery is too low, whether the battery has poor contact, whether the battery is broken, whether the battery socket is loose, whether the electric door lock wire is aged and falsely connected, etc. The fault may also be caused by the controller, but there is no rush to replace it. In addition to the power supply part, other external wiring should also be checked.

Master help! I am a new two-wheeled electric car bought online, only three months to start, sometimes the instrument lights and horns are normal, the motor suddenly failed to work, the electric door lock was re-opened and energized again, walk dozens of meters to hear the motor behind the sound of the power off, repeatedly, sometimes suddenly easy to use, riding more than ten days may suddenly be sick again! Asking the after-sales master didn't solve the problem, it's really sad!

Help! Thank you.

Answer: Hello dear! When the electric car is driving, it will be a brake, and this situation occurs mainly for the following reasons. The first thing to consider is that the battery is insufficient, the alarm prompt begins to appear, the battery power supply fluctuates, the voltage is high and low, and the voltage and current output to the driving electric vehicle are unstable.

It needs to be charged in time to maintain the normal output of the battery. The second is that the brake function of the battery car fails, and the brake pads are not sensitive to return after braking, and there are signs of braking in the process of walking. It is necessary to check the brake line, and if there is rust, wipe some oil lubricating oil to increase the smooth flow of the brake line.

Dear, hello, you can give a like after the topic is over, thank you, I wish you all the best.

Electric vehicles are due to: battery and wiring problems, lock connection and motor connection cable problems, poor line contact, etc.

1. Battery and line problems

Some customers feel that the battery is running low when they are riding the bike. Turn on the power, the power meter shows that there is power, and the ride is just walking, stopping, and not normal. At this time, you will have to go to the repair shop to check whether the total voltage power supply is normal.

Whether the battery is left alone (one piece is damaged) or the bulge cannot hold power, and the power output is insufficient.

2. Problems with the connection line of the lock and the connection line of the motor

These are all cases where there is a problem with the lock or the wiring that connects the lock. Sometimes the total output voltage measurement is normal, and the battery and battery connection cable are checked normally. Next, it is necessary to check whether the stationing point and connection plug line of the film Bipai are normal and have a short circuit in time, find out the problem and connect it well, and the problem can be solved.

3. Poor line contact

Check the power connection line of the electric door lock, the wiring port of the handle and brake, the connection between the battery and the body for looseness, the signal line of the electric door lock of the controller, and check the air switch.

etc., each wire can be replugged or tightened. Remove the battery compartment and open the lid to check the fuse.

Whether it is disconnected or short-circuited. with a multimeter.

Detect the voltage of a single battery, if the voltage is too low, then you need to replace the battery with a difference in the number of rows.

What to do if an electric car breaks down?

1. Clean first and then test

Many faults of electronic circuits are caused by poor working environment, such as high-voltage partial dirt will lead to high-voltage ignition, and dirty adjustable potentiometer will cause various possible soft faults. Accordingly, when checking for faults, the inside of the machine should be cleaned first, and the faults caused by pollution should be eliminated before testing.

2. First outside and then inside

electrical devices. There are quite a few failures, all of which have their external manifestations. Different external behaviors reflect the corresponding defects of internal components. When diagnosing and checking faults, start from the outside of the machine and work your way deeper into the interior.

3. Power supply before load

The power supply system is the energy supply center of the whole machine, the power supply is electric energy, the load consumes electric energy, and relies on electric energy to work. Therefore, when searching for faults, the power supply circuit should be checked first, and after confirming that there is no abnormality in the power supply, the functional circuit should be checked.
