Li-Lon Battery Management System for Trolley Bus

For the lithium-ion battery application on trolley bus, this paper presents a lithium battery management system for the trolley bus, this system can not analyze the battery fault condition online and tell the driver by graded alarm, but also can optimize the charge process. This paper analyzes the battery operation mode on trolley bus. Regarding the use and management issues of the original leadacid batteries, the paper also puts forward a more optimal and rational use and control strategy of the lithium-ion battery for trolley bus. Specifically, the paper carries out study in depth on the battery fault classification, SOC estimation, battery efficient use of capacity range, the charge current method in calculation, and also puts forward a variety of special treatment methods to coordinate with the safe and efficient use of lithium-ion battery on trolley bus.
