Technical overview

Technical overview – battery types

• 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 charging

• 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 – range/consumption data

• 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)


• 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
