Architectural selection
• System level trade offs require low fidelity yet accurate
models of motors, inverters and gearboxes to assess a
large number of options quickly
• Cost implications of decision being made are significant
Smaller gearbox/motor
Larger battery capacity
Larger inverter
Larger gearbox/motor
Smaller battery power
Reduced inverter demands
Vehicle targets and requirements
0-100kph: < 6s
0-200kph: < 30s
Top speed: 200kph
