12 Test Test summary No. Mode Departure Through Arrival Average speed [km/h] Average tracking power [kw] Average generatin g power [kw] Required generating power (average tracking power + 5kW) [kw] 1 Leaving work Seoul city hall Seobu expr. Ansan-si Leaving work Ansan-si Yeongdong expr. Yongin-si Go to work Ansan-si Gwacheon Seoul city hall Leaving work Seoul city hall Paju-si Go to work Paju-si Sinchon Required generating power should be considered with HAVC system and power conversion energy - 15kW generating power could meet the required performance of a car to aim city-driving 12

13 Reference test Getting away from the city 1) Satellite city 2) Go to provincial city 58km 37.1km/h 6.5kW 9.3kW 114km 73km/h 17.6kW 18.7kW 13

14 Reference test Long distance trip using motorway 235km 85km/h 23.5kW 27.6kW 14

15 Summary 1) Small generator(10kw) could meet the required performance of a range extended electric vehicle if the car is used in the city. 2) In the case that the REEV should go to the near city sometimes, the optimal generator power is 15kW. 3) If want to use the REEV to go somewhere away from the city occasionally, it needs 23kW level generator power. 4) To use the REEV everywhere, every time, without any anxiety of battery recharging, must be operated with high power generator over than 30kW, and the car also should be on the level of lower than B-segment. But why? recommend to buy just highly efficient small IEC vehicle. 15
