The influence of introduction of a plug-in buttery-electric bus (PBEB) with rapid charge system and a series-type plug-in hybrid electric bus (S-PHEB) without rapid charge system to an actual city-route on economic and ecological viewpoints was studied by simulation approach, comparing with for a conventional diesel bus. The specification of the city-route was as follows; one way, 4.5 km in 12 min.; required energy for a round trip, 6.7 kWh. The city area and heavy traffic part of JE05 mode was used as a bus-driving mode. As a result, it was found that the driving cost and CO2 emission of PBEB and S-PHEB were lower than those of the diesel bus. It was also found that 8 kWh was enough as a capacity of the battery on the PBEB. Then, the simulation was carried out with parameters of electricity mileage, diesel price rate and electricity price rate. Possible reduction in running cost was simulated to be 970,000 yen per year when diesel price rate was 100 yen and electricity price rate was 0 yen. It was indicated that when the electricity mileage increases, the running cost reduction and amount of CO2 emission reduction increase.
