Teach you how to buy electric vehicle batteries!

With the rapid development of the electric vehicle industry, the development of the electric vehicle battery industry has also become faster and faster. However, it is not difficult to find that the current market for electric vehicle batteries is too tricky. It is difficult to distinguish the true and false of the electric vehicle battery. Today, we will teach you a few simple ways to distinguish between good and bad electric vehicle batteries.　　How to detect whether the battery of an electric vehicle is good or bad? First, look at the appearance of the battery, whether there are traces of scratches or scratches, and then check whether there is rust on the positive and negative metal parts of the battery. In addition, some batteries will have anti-counterfeiting labels affixed to the butt of the battery shell, and you can see if it is normal. There is also the production date listed above.　　　　Secondly, see whether the new and old batteries for electric vehicles can be used together. If the old battery is connected to the new battery in parallel, it is like letting a person who works very fast and a person who works very slowly work together. The slowness can’t keep up with the fast ones, and the fast ones are also tossed to death by the slow ones. .　　 Finally, determine whether the battery has an internal short circuit. For electric vehicles that have been ridden for a while or left to stand for several hours after being charged, measure the voltage at the charging plug, and if it is 48 volts or higher, it is a normal battery (regardless of old and new). If it can only reach 46 volts or below, it means that there is a short circuit in one battery (the 48 volt car has four groups of batteries, and each group is connected to 12 volts by 6 2 volt batteries), and it shows that this group of 10 volts is a bad battery.　　How to check whether the battery of an electric car is good or bad? The above is just a simple method introduced by the author for you. We still recommend that everyone try to choose a big brand when buying electric vehicle batteries.
