Problems solved by technology

However, with the large-scale use of new energy buses, the mileage decline and safety risks of vehicles have gradually become prominent, which has caused drivers' anxiety about the mileage of new energy vehicles and increased the difficulty of dispatching the bus system.
In addition, due to the complex operating conditions of vehicles, the ambient temperature, humidity, road conditions, driving habits, charging habits, etc. of different vehicles are different. different degrees of recession
However, at present, there is no perfect prediction method to predict the battery life of new energy buses, and the health status of the power battery of new energy vehicles cannot be grasped, which leads to the limitation of the stable operation capacity of the public transportation system and causes a lot of inconvenience
