Description

technical field [0001] The invention relates to an intelligent, environment-friendly and energy-saving battery power supply system and method, belonging to the fields of new energy and electric vehicle manufacturing. Background technique [0002] Energy is the driving force of social development, and the environment is the carrier on which human beings depend for survival. The rapid development of the automobile industry has brought modern material civilization to the world, but it has also brought serious problems to mankind, such as exhaust emissions, noise pollution, and fuel consumption. Because pure electric vehicles have the advantages of zero emission and low noise, as an environmentally friendly means of transportation, they have very broad development prospects. However, the limited energy storage capacity, low energy utilization efficiency, and insufficient cruising range of electric vehicles directly restrict the development of electric vehicles. [0003] Pure e...
