Resumen
This paper aims to propose a methodology for managing Li-ion battery life for a whole fleet, focusing on improving the total operating costs for hybrid electric buses. This problem is approached in two different ways: bus-to-route and route-to-bus. Bus-to-route optimization focuses on developing an energy management strategy for each bus in the fleet. A techno-economic, energy and battery aging analysis of the fleet was carried out. As per the outcomes of this analysis, buses were grouped according to the state of health of the battery of each bus. Based on this analysis and classification, the routeto-bus approach was applied. This technique involves a re-evaluation of the energy management system and a reorganization of the buses according to the state of health of the battery of each bus. Increases in battery (BT) life of up to 10.7% were obtained using the proposed approach.
