1.How to deal with the Electric Car when the whole vehicle is out of power.

2. How to deal with the Electric SUV Car when it has power but does not move.
(1) Check whether the output of the Electric SUV Car battery is normal. If the output is too low, it means that the battery is bad. The battery needs to be replaced urgently.
(2) Pull out the brake line. If the car rotates, it means that the brake handle is broken and needs to be replaced or repaired. Use a meter 2 and a tube to measure the brake handle. It is a normal long-closed brake handle.
(3) Check the throttle and short-circuit the throttle positive and signal wires with iron wire. If the car rotates, it means that the throttle is broken and needs to be replaced or repaired urgently. Turn on the power and turn the throttle. Use a multimeter to measure the positive and signal wires. There is a positive 5V (1-4) throttle.
(4) Check whether the controller is good or bad. You can short-circuit the positive 5V of the throttle wire. If the throttle rotates, it means that the controller is fine. The simplest way is to smell the controller to see if there is a burnt smell. If there is, it means that the controller is broken.
(5) Check the motor. If the carbon brushes of the motor are not in good contact, it may cause the motor to not run.
