Teach you the correct way to replace the battery of an electric car

Nowadays, many customers want to replace the battery of electric vehicles. When they go to the after-sales repair shop, they will only ask for the price. As long as the price is cheap, the repair technicians do not need the technology and services. In fact, changing the battery is a technical activity. Good technology can make the battery play a normal life. Cleaning may have safety hazards. Generally, the short sense of responsibility of the technology will affect the life of the battery, and there may even be the risk of burning the car. The new motor power and new controller current for electric vehicles are an infringement on electric vehicle batteries. In addition, inferior chargers are dangerous to take the opportunity! The following is my ten-year experience in electric vehicle maintenance, talk about me The battery-related experience: top, the correct device battery. It is best to change the original line of the new battery, the battery connection is long, the line is aging, the contact is poor, the simple short-circuit fire, the soldering iron uses 50-60w to solder the battery stack as much as possible, and the pile should be wrapped with insulating tape to prevent the bicycle from breaking down. OK, troublesome! Then use the battery instead of the battery box to separate the battery, so that there is space for heating, and the battery in the battery box will not collide! After all, move the battery to the car, such as moving the battery box to a fixed place It is best not to let it sway back and forth, to prevent the battery from closing badly and causing a leakage night. Second, check the braking power. Some repairers simply install the battery. In fact, the brake power is also very important. The brakes are not safe to ride, and the waste of unnecessary power can easily break the battery's life! Third, debug the brakes and check the front and rear rolling resistance. There are many bicycle lanes with brakes. Adjusting the rolling resistance before and after the brake can also make the electric vehicle go further. Fourth, the movement joints of the key parts are filled with oil. When refueling, it can rebound sensitively and reduce conflicts! Make electric vehicles more energy-saving and longer battery life. Fifth, check the air pressure. Let the air pressure be moderate, low air pressure will also affect the trip, high air pressure will simply blow the tire! Sixth, inform customers of the charging precautions. When the rotating handle has one or two power grids left, it should be charged. The first three charging of a new electric car takes about 10-12 hours. Charging for 6-8 hours in summer and 8-10 hours in winter. Prevent forced driving without power, causing over-discharge to affect battery life. The above processes are what a professional repairer should do to replace the battery. The replacement of the battery is really not just as simple as the price. It is actually very important to choose a professional repairer depending on the master's technology and services. Regarding our electric vehicle repairers, we cannot change the quality of the battery, but we can try our best to prevent these accidents from happening, and do our best to make the battery of the electric vehicle last longer and safer. It is no exaggeration to say that a good teacher can use a battery for three years, and a poor teacher can use it in less than a year. The key depends on your own choice.
