Riding an electric bike too fast is harmful to the battery?

Walking on the street is always frightening, not afraid of motor vehicles, but electric vehicles whizzing past you. Especially when waiting for the red light, just jumped to the green light. A group of young high school students rushed forward one by one, as if they were in an electric car race, and no one wanted to fall behind. Seeing such a scene, the author is really sweating for them, but still can’t help feeling that it’s good to be young, but will electric cars really be 'young and good' as always? 　　 As everyone knows, electric cars have their own cycle life. The life span is affected by many factors. Like a group of high school students, will the speeding of electric vehicles affect the battery? A master at an electric bicycle repair shop said that he has repaired at least dozens of brands and several electric bicycles. Hundreds of vehicles, speeds exceeding 20 kilometers per hour are common, and speeds of up to 40 or 50 kilometers are not uncommon. Online information shows that the technical threshold of the electric bicycle industry is not high. After some simple modifications, the speed of the car can easily exceed 80 kilometers per hour, catching up with the car. It seems that this kind of speeding phenomenon has been taken for granted. However, in general, the cruising range, discharge rate, and working current of electric vehicles have corresponding standards, while the working current of speeding electric vehicles is far greater than the prescribed standards. The battery is in a state of high current discharge for a long time, which will damage the battery greatly. Because of the high current discharge, the lead sulfate formed at the solid-liquid junction has a large degree of supersaturation, so that the electrode plates form more lead sulfate crystals. As time goes by, the crystal grains will become coarse and charge irreversible sulfation, resulting in Difficulty charging. The separator will also precipitate lead to generate dendrites to form a micro-short circuit, and also cause many microcrystals to fall off during the charging process, causing damage to the battery, and in severe cases, it will cause the battery to fail. Warm reminder of high-quality electric vehicle battery brand batteries: When we ride electric vehicles, we try our best to use them as required. On the one hand, not only can the battery last longer but also allow you to travel farther, on the other hand, you will drive more at the speed limit. Safety, greatly reducing the probability of traffic accidents. Remember, don't drive too fast. Previous post: Shocked! Common problems of electric vehicle batteries are so easy to solve
