3E24 Rational placement of charging-station for Lithium-ion battery onboard of rail vehicles(Electrical-Vehicle)

抄録

The train on energy storage device called on-board rail vehicle is able to store regenerative energy on storage at breaking and run under catenary-free condition, but we must think how to charge to energy storage device. If it charged at station during stopping, it has one of the methods that include the charge from catenary. Then, if run the on-board rail vehicles for long railroad, the major problem is where to place the quick charging points. We propose to be focused on energy consumption by appropriate placing of charging stations because energy storage device dropped the open circuit voltage as SOC (state of charge) decrease and became low tractive force of motors. As a result, the low SOC caused more energy consumption for running trains. In this paper, we create a mathematical model of onboard energy storage train with an onboard high-power rechargeable lithium-ion battery under catenary-free conditions and placed of charging station and simulated to know relationship between electric energy and running under different SOC. Furthermore, we make the line model of 90[km] in total length and simulated the train electric energy consumptions the change of the electric energy consumptions by changing station to put on 2 patterns. We consider the change of the electric energy consumption by the difference of the charging station and suggest the systems of the onboard energy storage train, which can run on catenary-free condition.
