Range

Some rough estimates by assuming that we will have an energy use similar to ProEV and making use of some of their published data (more data here):
 * Race pace: 0.75 kWh/km (aerodynamically the Saker will be slipperier, but we only have rear wheel regen. To be safe bump this estimate up by 10% to give us 0.825)
 * Warm up pace: 0.15 kWh/km (which is ~double 0.081 kWh/km which is what ProEV estimate for road driving)



NZSC Series distances: Energy storage required (kWh): Required usable battery capacity ~ 23.31 kWh
 * largest event is 9 laps of ~3km circuit = 27 km
 * Plus warmup lap = 30 km
 * Plus victory lap = 33 km.
 * Warmup: 3km x 0.15 = 0.45 (this might be an underestimate)
 * Race laps: 27km x 0.825 = 22.41
 * Victory lap: 3km x 0.15 = 0.45

Being more generous with the warm up, we will double the required energy (e.g. 3km x 0.3): Required usable battery capacity ~ 23.76 kWh
