Conceptual Design for Modifying EV Minivan Bus for Korat City

Abstract

This paper proposes the conceptual design for modifying minivan as an Electric Vehicle (EV) for driving as the bus in Korat city. The normal bus of Korat city is a minivan using diesel engine. The EV equipment is considered to replace a diesel engine of minivan bus. The approximated weight and routine routing are used to calculate the motor and battery storage sizes. The route length is 25 km and minivan stop point is 28. The results of conceptual design show that the EV minivan uses a permanent magnet synchronous motor (PMSM) 60kW and 46kWh Lithium Nickel Manganese Cobalt Oxide (Lithium-NMC) battery can run around for 10 rounds (250km.) a charging. The maximum speed of EV equipment selection is 150km/h. Thus, the EV charging station can be installed at the route parking station.
