Nine Questions and Nine Answers to the Use of Electric Vehicles

There will always be some small problems during the use of electric vehicles. Let the master show you today! 　　一: How many hours do you need to charge the new battery for the first time for a new electric vehicle? Is it used up or first? ?　　Answer: The first charge must be fully charged. If the charge is insufficient, it is recommended to charge for about eight hours. If the charge is full, the charger will turn green and continue to charge for another half an hour. The future batteries can be used as needed. When charging, don’t use the battery to the lowest level. Generally, it is best to charge when the battery is 60%-70%. Be careful not to overcharge when charging.　　二: My battery is full in less than two hours. Is it necessary to repair it? 　　 Answer: This is because the battery has been used for a long time. Three: What should I do if there is a place where the paint is dropped on the electric car? Can it be repaired? 　　 Answer: If you have a small area, you can self-paint and add varnish. If you have a larger area, you can consider filming. If you have a strong ability to do it yourself, buy the film on Taobao and apply it yourself. .　　4: The electric vehicle is out of power, what should I do? 　　Answer: 　　 (1) Check whether the battery has an output wire and whether the welding is open.　　 (2) Check whether the fuse holder is good or bad.　　 (3) Check whether the power lock is good or bad.　　5: What should I do if the car is powered on? 　　 (1) Check whether the battery output of the electric car is normal. If the output is too low, the battery is bad, and the battery needs to be replaced urgently.　　(2) Unplug the brake cable. If the car turns to prove that the brake lever is broken, the brake lever must be replaced, or the meter 2 and the tube measuring brake lever must be used for maintenance (normal long closed brake lever).　　(3) Check the handlebar, and short-circuit the handlebar and the signal line with an iron wire. If the car turns, it proves that the handlebar is broken and needs to be replaced or repaired urgently. Turn on the power and turn the handle, and use a universal meter to measure the positive 5V 〈1-4〉 handle of the summing line and the signal line.　　(4) Whether the controller is good or bad, you can short-circuit the positive 5V of the switch cable. If the switch is turned, the controller is okay. The easiest way is to smell the controller for burning. If it does, it proves that the controller is broken.　　(5) Check whether the motor is good or bad. Incorrect contact of the motor's carbon brushes will also cause power failure. Six: I bought a new electric car today. When I go home, I find that the headlights will not go out directly when they are turned off. It takes more than 10 seconds to go out.

Eight: Why does the battery life of the motor have a long or short life? 　　 Answer: During the development of electric vehicles, 150W-180W motors and 12AH batteries are generally used. During this period, the battery life can reach 2-3 years. With continuous improvement, customers suggest that the speed of the car is slow. The motor is changed to 350W-500W, and the battery is changed to 17AH-20AH, but the battery is used for 6-10 months. Some manufacturers use 700W motors to prove that the motor output power is large, and as long as the battery life is decreasing, it proves that the speed is not perfect. Nine: How come the electric vehicle battery can't run the kilometers you mentioned? 　　Answer: Either the dealer falsely reported the kilometers; or it was used improperly. In addition, as in winter, 30% of the lead-acid battery discharge is stored in it in winter. Therefore, the avoidance of battery running is actually less.
