Description

technical field [0001] The invention provides a lithium battery pack based on a fast charging protocol, which belongs to the technical field of batteries. Background technique [0002] With the development of science and technology, lithium battery chargers are used more and more widely. Lithium batteries have been widely used in mobile phones and digital fields, but the batch application of power lithium batteries has only started in recent years. With the development of the sharing economy and the increase of people's demand for fast and short-distance transportation in the city, lightweight and easy-to-use electric bicycles have broad market prospects. The power source of the electric bicycle comes from the battery, and the existing electric bicycle lead storage battery has the problems of heavy weight, fast failure and slow charging. Indirectly lead to a decline in the efficiency of people's travel and movement. As a battery type with many advantages such as recyclabil...
