  12. Technical overview

  13. Two types of battery: ZEBRA molten salt (Ni Na Cl) Lithium ion (LiFePO4) Two capacities in producton: ZEBRA: 84 kW.h (~160 km) Li ion: 48.12 kW.h (~100 km) Future capacities: Li ion: 80.6 kW.h ? Technical overview – battery types

  14. Chargers are presently off-board Development of on-board solution underway Off-board charger efficiency varies with time: 24h on charge: ~65% (R101 report estimate) 12h on charge: ~82% (R101 report estimate) 6h on charge: ~95% (R101 report estimate) Technical overview – battery charging

  15. ECE R101 testing: Carried out on Li Ion Regenerative braking disabled by test method Range results: Half-laden: 123 km Unladen: 142 km Consumption results (based on 24h charge): Half-laden: 571 W.h/km (at mains) Unladen: 502 W.h/km (at mains) Technical overview – range/consumption data

  16. Technical overview – range/consumption data • Modec indicative testing: • Regenerative braking enabled • @ GVW (5500kg) • Aggressive driving (mean 42 km/h, 22.4% demand) • Results: • Li ion: 481 W.h/km (at battery) • 740/587/506 W.h/km at mains • Implies range of 48.12 kW.h pack is: 100 km

  17. Technical overview – range/consumption data • Modec indicative testing • Regenerative braking enabled • @ ULW (~3800kg) • Low-speed driving (mean 23.4km/h, 10.1% demand) • Results: • Li ion: 321 W.h/km (at battery) • 494/391/338 W.h/km at mains • Implies range of 48.12 kW.h pack is: 149 km

  18. Technical overview – range/consumption data • Modec indicative testing • Regenerative braking enabled • @ ULW (~4000kg) • High-speed driving (mean 55.3km/h, 15.8% demand) • Results: • Li ion: 367 W.h/km (at battery) • 565/448/386 W.h/km at mains • Implies range of 48.12 kW.h pack is: 131 km

  19. Customer experience: Varying loads, varying driving styles, lithium ion chemistry cells Typical daily usage: ~24 km to ~72 km Typical consumption at battery: 436 W.h/km: 671/532/459 W.h/km (at mains) 541 W.h/km: 832/660/570 W.h/km (at mains) Implied total range: ~89 km to ~110 km Technical overview – range/consumption data
