  7. Test result (WLTP vs. JC08) Measurement point of energy consumption Battery Motor

  8. Test result (energy consumption of L,M,H,ex-H in WLTP) Measurement point of energy consumption Battery Motor “Assumed range” is a range that was calculated on the assumption that the test vehicle was frequently driven in each part of the WLTP. Definition ⇒ X = (13/Y) × A 13kWh: Fully charged energy in the battery

  9. Test result (AC200V vs. AC100V in a charge) +14% +120% 9

  10. Test result (AC200V vs. AC100V in a charge) +14% +120% Which Voltage should be provided on gtr? 10
