Vehicle2006 Mazda RX8
The original car was purchased for the conversion but it was so good to drive the conversion didn't start for 30 months.
Motor Shenzhen Greatland GLCP25L1 3-Phase AC
MAX 80KW, 250nm, 5000rpm.
Water cooled
DrivetrainMotor drives through new flywheel & HD clutch to the manual 6sp gearbox and std diff.
ControllerShenzen Shenzhen Greatland GLCP7024L11
Rod @ EV Power designed a throttle mapper to enable the accelerator and motor controller to communicate.
Batteries90, 3.20 Volt, Lithium Iron Phosphate
100Ah / 30KWh battery pack.
24 cells under the bonnet, 24 over the rear axle and 42 forward of the rear axle.
Battery boxes made by EV Power.
EV Power designed the BMS that interfaces with the individual cell modules. ev_power.com.au
System Voltage328 Volts
Charger
A 2KW and a 4KW via J1772
HeaterThe controller and motor heat the water that goes through the cabin heater core, this is sufficient to demist the windscreen in winter in the SW of West Australia. The A/C compressor is bolted to the motor frame but requires a drive motor to be fitted and the condenser to be refitted.
DC/DC Converter
The electric power steering (EPS) is connected to the DC/DC.
InstrumentationEV Power battery monitor.
Brake vacuum gauge.
Top Speed90 MPH (144 KPH)
Range100 Miles (160 Kilometers)
130km at 100 ~ 110kph.
160km at 80kph
EV Miles
Start:68,000 Miles (109,412 Kilometers)
Current:73,500 Miles (118,261 Kilometers)
Total:5,500 Miles (8,849 Kilometers)
Seating Capacity2 adults
Curb Weight3,521 Pounds (1,600 Kilograms)
200kg heavier than the original ICE, it's now about 1600kg and the balance is still 50/50.
Tires225/45 R18
Conversion TimeManhours??
From ICE to EV 32 months.
The mechanical work was carried out by myself, most of the electrics by EV Power.
Conversion Cost>AUS$25,000
Additional FeaturesCVR rotary vacuum pump and a vacuum reservoir.
The original oil cooler is used as a radiator.
The original engine speed sensor has been fitted to line up on the edge of the clutch to give a tacho signal to the ECU to energise the EPS.
SW Machining in Busselton made the flywheel and fitted the CanEV gearbox adaptor plate to the motor.
Rotomotion in Maddington WA manufactured the motor frame to fit the original 'Wankel' mountings and modified the flywheel hub.
In the future; I would like to change to faster DC charging and as battery technology improves go to a lighter and larger capacity battery pack and also a higher revving motor.
