I'm planning to meet with Good Prius Friend Hobbit at the Lookout Mountain hang gliding center about 90 miles away. This gives me a chance to re-record the data across multiple driving conditions:
Nuvi GPS: o velocity - true
o altitude Graham Miniscanner o MG1 rpm
o MG2 rpm
o ICE mass airflow
o MG1 torque
o MG2 torque
o traction battery amps From these metrics, we can calculate: indicated_mph = k * MG2_rpm
ICE_rpm = F(MG1_rpm, MG2_rpm)
ICE_hp = F(MG1_torque, MG1_rpm, MG2_rpm)
plot operating BSFC
plot true mph vs MPG
plot power split device efficiency
plot power split device power levels
hill climb efficiency vs mph For grins, I may change the ICE oil at the flight center and measure the effect on the way back.
