Electric car repair technology?

The first time to learn electric car repair technology is recommended to start with the following points:

1. Check the appearance of the vehicle and the degree of intactness of the various components, the obvious damage and missing parts to make a record.

2. Check the technical status of the vehicle:

(1) check the main screws and nuts fastening degree. Mainly include the handle bar and handlebar joint screws between the degree of fastening, saddle clamping bolt fastening degree, the center axle lock nut fastening degree, front and rear wheel fastening degree.

(2) Check and keep the contact terminals for battery power output clean. Check and keep the contact of the lead connector good.

(3) Test the plugging and unplugging strength of the power connector to avoid the electrical failure of the whole vehicle or the reduction of the efficiency of battery energy utilization caused by poor contact.

(4) Check whether the car bell, lights, display instruments and brake braking system work normally.

3. Test drive the vehicle according to the correct riding method.

4. Refer to the common fault phenomena and troubleshooting methods of electric bicycles described in the "Reference Materials", combine with the experience of test-driving, whether there are any faults in the vehicle and troubleshoot the faults with the permission of the instructor.

Every day the battery is fully charged once a day, each charging time for 8 to 12 hours, so that the battery at any time to maintain the state of abundant electricity, its life has great benefits, if not timely charging after riding, will greatly affect the service life of the battery. If the battery is not charged in time after riding, it will greatly affect the service life of the battery.

7. E-bikes should be accelerated slowly when starting; in the larger slope on the road and driving against the wind, it is best to pedal to avoid high-current battery discharge, in order to extend the life of the battery and motor. And can avoid burning electrical components.
