3 Our purpose Developing cars for a different tomorrow Corporate Presentation

4 CEVT is an innovation center for the Geely Group > Started 2013 >A Swedish registered company, owned by Geely(ZGH), located at Lindholmen Science Park in Gothenburg. > Currently keeping some 2000 people busy. >Aprx3B SEK annual investment. > Offices in Gothenburg and Trollhattan About CEVT

5 Zhejiang Geely Holding Group CEVT s role Owned by Geely Holding Group Operates under GAG Delivers technology to GA, LYNK & CO and Volvo Cars

6 CEVT

7 First car launched for LYNK & CO The 01

8 Electrification of CMA (Compact Modular Architecture)

9 Electrification Strategy > PHEV first HEV second > Single E-motor hybrid solution > All HV systems in the front > Short HV lines and easier installation > HV Battery placed centrally > Crash safety > No impact on tank or luggage volume > E-motor on top of a standard gearbox > High commonality with standard gearbox > Same powertrain installation as non-hybrid

10 Electrification of Transmission: > Based on high-volume 7DCT transmission > Only few added components > Motor attached to even input shaft > E-drive and regen on gears 2, 4 and 6 > Hybrid drive on all gears 390 Nm

11 The Energy Challenge

12 Challenge increases Customers are buying larger and more powerful cars US market data Global weight data China market data Data source US EPA Data source Lee Schipper, University of California Berkeley Data source ICCT

13 Taking weight out of the equation? Kineticenergyrecoveryreducesthe importanceofweight, however size matters! Electrification enables regeneration of acceleration power. If we would have 100% efficiency weight would not effect energy consumption. Larger vehicles require higher power higher energy consumption Power = m*a*v Power [kw] 25,0 15,0 5,0-5,0 Power neededon a flat road SUV Sedan Speed km/h

14 The CostChallenge Electrificationis needed, howdo wemake it affordable? 08/02/2018

15 Electrification is needed, size of the battery? Daily driving distance to determine the installed capacity? km rangecovers a large part of customers daily driving. Customer surveys indicate that 80km range would satsify most customers today Chinese study of driving behaviour /02/2018

16 Range neededfor a BEV? The size of the battery for long distance travelling should cover the range between coffee breaks With fast charging the car canbe chargedwhilethe driver takes a natural break. Expectation is that three hoursofdrivingshouldbe covered. ~400km 08/02/2018

17 Whatis the costofthe futurept? Cost challenge is mainly connected to battery size Powertrain relative costestimation2025 Different customers will choose different powertrain solutions. PHEV competetivefor long range Relative Cost 2,2 2 1,8 1,6 1,4 1,2 1 Assumptions: Same powerlevelson all PT. PHEV assumed50% powerfrom e-motor. 0,8 0, Range [km] BEV pwt 50 km PHEV pwt 100 km PHEV pwt 08/02/2018

18 Howdo wereachan affordablecost? Electrification technology is not mature. We need to cut cost by optimising and finding economy of scale Example High voltage batteries: numerous solutions ofcells, modulesand batterypacks. The automotiveindustryand in the end, the customer will benefit from standards High voltage Cells 08/02/2018

19 Howdo wereachan affordablecost? Further integration is needed in order to reduce cost Combining functions into one unit is a must. IntegratedInverter/e-motor Combined Charger & DCDC 12V battery combined with High voltage battery Inverter& Charger etc many combinations possible As volumes increase unique solutions does make sense. Modularity might not be the soleanswerto cuttingcost 08/02/2018

20 Howdo wereachan affordablecost? PHEV & HEV allowusto reducecostby optimisingthe ICE Expensive technology aimingat lowload efficiencycanbe removed Lowspeed torqueis also less interesting Cost reductions possible 08/02/2018

21 Whatis neededin the future? Significant research and development is needed! Increased power& energy density is needed from HV batteries Improved power density from e-motors Increased temperature tolerance from HV batteries, e-motors and power electronics Improved charging infrastructure Standardised wireless energy transfer 08/02/2018

22 Conclusions >Electrification is here to stay >Cost of electrification will come down with new innovation >A diversity in Powertrain technology in the near future is to be expected CEVT is dedicated to finding the solutions bringing us into the future
