Research on a New Lithium Battery Applied in Onboard Energy Storage Device of Light Rail Vehicle

摘要

The on-board energy storage device can absorb the regenerative braking energy of light rail vehicle to be used as traction energy, and stabilize the traction network voltage. This is a hot spot in the field of urban rail transit in the last few years. In recent years, the emergence and development of the power type lithium titanate batteries have been greatly improved in the charge and discharge efficiency, cycle times, cost and performance of the battery, which meet the requirements of onboard energy storage devices of light rail extremely. If the new type battery is suitable for light rail transit as energy storage device, it is the subject of this paper. The paper proves the application feasibility from the aspects of the energy storage system structure, the simulation model building, the charging and discharging control strategy, the capacity allocation and the economic benefit.
