Characteristics of Lithium-ion Battery Applied to Electric Bus during Running Tests

Abstract

Using lithium-ion batteries that have higher energy density than lead-acid batteries, we assembled on electric bus and tested it as a base vehicle. The nominal voltage and nominal capacity of the battery packs are 365V and 120Ah, respectively. 15Ah lithium-ion battery, composed of 2 cells in parallel and 96 of pairs of what connected in 4 parallel, was applied to the bus. The bus was demonstrated over one year. In this paper, the characteristics of the 120Ah lithium-ion battery, the specifications of the bus system and field-test results are described.
