Street fast chargers are no longer a novelty. When electric vehicles run out of battery, they may become the "savior" of electric vehicles. But it is also possible that charging only once will damage the battery of the electric vehicle, and Ms. Zhang, a citizen, has encountered such trouble.

Ms. Zhang, a citizen, just bought a lithium battery electric bike last year and rides it to and from work. "After being fully charged, it's not a problem to run for two or three days." A few days ago, when she rode her bike to work, she found that there was not much battery left in her electric bike, so she thought of finding a fast charging place to charge it first.

Ms. Zhang rode her bike to a fast charging stall at the entrance of the city's traditional Chinese medicine clinic. For the sake of insurance, she specifically asked the vendor if the electric vehicle with lithium batteries could be charged quickly. At that time, the vendor told me that he had charged hundreds or thousands of electric vehicles there without any problems, and lithium batteries could also be charged. That's why I confidently put the car there to charge

But when Ms. Zhang went to pick up the car, she found that not only was the electric car not charged, but even the last bit of electricity was gone. I went to the repair shop and the staff told me that the fuse on the battery was blown, which was caused by the street fast charger. Later, Ms. Zhang consulted the manufacturer of the electric vehicle battery, and the customer service representative said that lithium batteries should never use street fast chargers, otherwise it will cause battery damage.
