Electric vehicles have become an indispensable travel tool for people. They are comfortable to ride and low in cost. They have become a favorite means of transportation for the people. They don't have to be dilemmas for traffic jams, they don't pollute the air, and they don't have to worry about finding a parking space...so Traveling must be an electric car, giving you different speeds and passions!
When the electric car is not controlled, it is also a "flying car", which is particularly dangerous. Electric vehicles should be regularly maintained, check the line and main components, and if problems are found, repair them in time! Wait until there is danger, regret it later! The following describes the repair methods and precautions for the electric vehicle "speeding":
The electric car "speeding" is to turn on the power supply motor, the speed control is not controlled by it, and the speed is very fast! There is no need to panic, first brake, use mechanical brake to slow down until stop, one hand does not loose the brake lever, the other hand closes the electric door lock, or unplug the power cord and remove the battery, and finally electric The car supports the rear wheel to solve the problem. The reasons for the "speeding" failure are:
Reason one: the circuit is connected to water. The controller speed control wire is mostly contacted by the connector. It is easy to connect the turn signal line with the positive pole of the switch after entering the water. Some controllers are prone to danger without anti-air protection! Cause the speed!
Treatment method: It is best to remove the connectors with insulating tape to fix them one by one, and use two wires to reduce the risk of flying!
Reason 2: The speed control turns the line and the controller to the negative line. Disconnect the handle, if it is normal, the controller is normal, it is the speed control and its speed control line fault! Some lines are aging or bumpy, which may cause the connector to be insecure. If the negative line is broken, the controller will appear "speeding"!
Treatment method: replace the speed control line, replace the red, blue and black lines from the controller to the speed control! It is best to remove the connector and connect directly! In order to avoid bad contact!
Reason three: The speed regulation is faulty. Pull the speed off the line, the car will not "speed", then it may be that the speed control is broken! The speed control is mostly with the "Hall" speed control, and the damage of the original Hall may make your car stop!
Processing method: first detect the polarity of the lead wire of the controller, the +5V line is connected to the red line of the switch, the negative line is connected to the black line, the blue signal line is connected to the blue line, and the electric vehicle has the reverse line of the three wheels. , the reverse line is the switch line can be connected!
Cause four: The controller is faulty. If the controller power tube is broken down, the speed of the vehicle will also fail.
Solution: Unplug the controller and turn on the power, or turn on the power. It is a fault inside the controller and the controller needs to be replaced.
Reason 5: Simple models with power-assisting function. Some chain flywheels rust and lead to continuous continuous rotation, as long as the "foot kick" rotation assist will play a role in boosting, if the "foot kick" automatically turns, the car will go forward "窜".
Treatment: Replace the flywheel to prevent danger from being assisted!
The automatic operation of the electric vehicle is not easy to be dangerous due to the uncontrolled operation. Please check it in time to avoid accidental loss! Only the electric car is controlled by you, you can ride safely, don't let the electric car control you, threaten your life! There is electric travel, let people follow, don't let the electric car "rush"! There is a problem with the speeding problem...
