As an electric car owner, do you feel that your speed is getting slower and slower?
As an electric vehicle owner, do you feel that your speed is getting slower and slower? Many people will suspect this is the cause of the battery when they encounter this problem. Although this happens, it is not related to the battery, but it is not only a problem with the battery, but also a malfunction of the motor, brake, tire pressure and other components.
Then the speed of the electric car is slow, what are the reasons?
Insufficient battery power: As we all know, the battery is the core of the power output. When the battery power drops to the undervoltage point, the speed will drop. This is because the controller has an undervoltage protection function to prevent the battery from being over-discharged and causing battery damage.
Solution: Fully charge the battery. If it can't be solved, it may be the battery aging. It is recommended to replace the battery.
Motor magnetic steel demagnetization:
1 electric vehicles for long-term overweight, overload, climbing, will make the motor magnetic weakening, magnetic steel demagnetization;
2 Long-term high temperature work will also cause heat accumulation inside the motor, causing the motor to demagnetize. Therefore, the longer the motor is used, the weaker the power and the slower the speed.
Solution: Go to the repair shop for repair or replace the new motor.
1 Due to long-term exposure to the outside, the brakes may produce rust or foreign matter, which may cause the brake rocker arm to be inflexible, difficult to return to, and accompanied by brake resistance to slow down the speed;
2 The brake pad is too tight or the brake rebound is not complete, which will cause the brake to always rub the motor, resulting in slower speed.
Solution: Go to the repair shop to maintain or replace the brakes.
Insufficient tire pressure: When the tire pressure of the electric vehicle tire is insufficient, the friction and adhesion of the tire will increase, thereby increasing the resistance of the electric vehicle and affecting the speed of the electric vehicle.
Solution: Inflate the tires, but avoid inflating too much!
Finally, the warm reminder: When the electric vehicle fails, please go to the service outlet for maintenance, and protect your safety!
