Is the acceleration of electric scooters weak? See if the two lines on the car are reversed?

Second-hand cars are gradually recognized by the public because of their low price and performance as much as new cars. The transaction of second-hand cars has been hot in recent years. I believe that many car users have bought second-hand cars. I don’t know if you have any acceleration problems. Anyway, when my car had a problem with the industrial design company, I was passing a big intersection, and I was in full view. It was very embarrassing to cross the intersection at turtle speed!

I originally thought it was a battery aging problem. After all, as a used car for more than two years, it is normal to have problems. So I didn't have to consult too much, so I went to the store to change the battery confidently, but it was still difficult to speed up.

I originally thought it was a battery aging problem. After all, as a used car for more than two years, it is normal to have problems. So I didn't have to consult too much, so I went to the store to change the battery confidently, but it was still difficult to speed up.

After a while, I found a professional master. It turns out that the electric door lock signal input line of the vehicle controller has been swapped with the power input line. Once the power is input through the electric door lock, the electric door lock contact and the connection wire of its alternative material have high resistance, which will cause serious heating of the vehicle motor and reduce the current through the motor, resulting in insufficient motor power and providing the vehicle's acceleration ability Significant decline, this is the so-called poor acceleration. Finally, after adjustment, the vehicle returned to normal.

The editor of the scooter design company also summarized some other possible reasons for the lack of acceleration of electric vehicles:

1. The vehicle battery is damaged. It can be tested with a universal meter.

2. The handle of the vehicle is damaged. The inability to increase the speed has a lot to do with this, and the output power of the motor is controlled by it. The mechanical material is different from the traditional motorcycle, so it is prone to failure.

3. The motor is damaged. Changing the motor is expensive, so it's better to change to a new car with high cost performance.
