Research and design of lithium battery management system for electric bicycle based on Internet of things technology

Compared with ordinary lead-acid batteries, lithium batteries are gradually favored by more electric bicycle manufacturers due to their high energy density, high charging and discharging efficiency and other properties. In order to ensure that the operating status of the rental battery pack applied to electric bicycles can be monitored by the operating units in real time during charging or discharging, a lithium battery management system for electric bicycles is designed. The battery management system can monitor the voltage, current, temperature, energy storage and location information of the battery pack in real time, and transmit information to the cloud management platform in real time. The system has been used in the leasing battery products of a battery leasing enterprise.
