4. 2. Overview of Test Procedure

5. 3. Unique Measurement Items and Specification

6. 4. Unique Procedure before Testing • 4.1. Battery Initial Break-In Procedure • break-in distance for battery • necessity of unique break-in procedure for OVC type vehicle (battery and other power sources) • 4.2. Determination of the Road Load Power • develop road load determination procedure for the vehicles with no mechanical neutral position • usage of table R/L setting value • 4.3. Battery Pre-Conditioning • necessity of additional driving for EV/OVC range test • necessity of battery discharge procedure before vehicle pre-conditioning • atmospheric conditions during battery discharge

7. 5. Battery Charge • 5.1. Normal Overnight Charge Procedure • necessity of discharge process before charge • charge method, on board charger or external charger • ambient conditions • 5.2. End of Charge Criteria • specific duration or instrumental indication • need to consider the completion timing to match the soak duration • 5.3. Limit of Charge Duration • should be equal or less than maximum soak duration • necessity of additional limit criteria, like

8. 6. CD Test • 6.1. General • duration criteria between battery charge completion and CD test start • definition of transient cycle • 6.2. Emission / Fuel Consumption • treatment of transient cycle for OVC type HEV • 6.3. EV (OVC) Range Test • end of range test criteria for BEV • consider the shorten procedure for BEV • treatment of transient cycle for OVC type HEV • 6.4. Energy Consumption • charge start timing after completion of discharge driving • end of charge completion criteria

9. 7. CS Test • 7.1. Pre-Conditioning • battery stable driving (manufacture recommended) before pre-conditioning for OVC type HEV • 7.2. Emission /Fuel Consumption • compensation of electricity balance for (emission and) fuel consumption for HEV • necessity of electricity balance compensation for OVC type HEV (if no, 7.3 must be required) • necessity of electricity balance criteria for test validity • 7.3. Energy Consumption • necessity of battery charge energy measurement after CS test (if no, 7.2 second “ ” must be required)

10. Additional Test CD Test CS Test ENG ON ENG ON …… Cold Hot Cycle #1 Cycle #2 Cycle #3 Cycle #4 Cold ( US and JPN) 8. Emission Worst Test For OVC type HEV, the calculation formula of the emission results are differ among EU/US/JPN regulation. EU : EMTOTAL = Combined EMCD and EMCS/HOT by range weighting EM = independent each cycle US : EMCD = Combined EMFIRST ENG ON CYCLE and EMFOLLOWING TWO CYCLES EMCS = Combined EMCS/COLD and EMCS/HOT JPN : EMTOTAL = Combined Worst EMCOLD (include Additional Test) and EMCS/HOT

11. 9. Calculation • 9.1. Emission • compensate based on electricity balance for HEV • worst emission or combined* emission for OVC type HEV • 9.2. Fuel Consumption • compensate based on electricity balance for HEV • combined* fuel consumption for OVC type HEV • 9.3. EV (OVC) Range • cycle unit or equivalent all electric range (km unit) for OVC type HEV • 9.4. Energy Consumption • combined* energy consumption for OVC type HEV • not convert to equivalent CO2 value *) “combined” with CD and CS test results weighted by utility factor

12. 10. Appendix • 10.1. Utility Factor • describe how to develop the utility factor for OVC type HEV • develop the harmonized utility factor for OVC type HEV, if necessary • 10.2. Compensation of Electricity Balance • develop the test procedure for HEV • exempt criteria of electricity balance compensation

19. IV. Introduction of SAE J1634 Draft -1 SAE J1634 revision is considered for the purpose of the test efficiency of EV. The procedure of “Abbreviated” as reduction of the test day is the followings. 1st : DC energy consumption test 2nd : Battery capacity test 3rd : Charge test Start charging Start driving with full charged Mode Driving Discharge Driving @ Constant Speed • DC energy * measured as UBE • Drive range measured • Vehicle DC Energy *cycle Next day *) DC energy measurement (@ battery power outlet point) require special equipment • AC energy measured as BRE The method of steady speed driving for battery capacity test is following. • Start vehicle and accelerate to 55mph within 30 sec • Hold constant speed for 50 min, then stop and key-off vehicle. Soak for 10 minutes • Repeat above sequence until either: • Vehicle cannot maintain a speed within 2 mph of hold speed for more than 2 sec • Vehicle indicates limited performance or zero-charge operation • Once test termination has been reached, decelerate to a stop within 30 sec

20. IV. Introduction of SAE J1634 Draft -2 The equation of each value are the followings as MCFD. MCFD : Multi Cycle Full Depletion UBE (Vehicle DC Energy from full-depletion test) BRE (AC Charge Energy from full-depletion test) CEF= UBE Vehicle DC Energycycle MCFD Rangecycle = x Distance Drivencycle Vehicle DC Energycycle CEF MCFD Recharge Energycycle = MCFD Recharge Energycycle Distance Drivencycle MCFD AC Energy Consumptioncycle = Steady speed test is considered as the full-depletion test.
