Description:This was my first EV conversion, and was a great learning experience. The difficulties I encountered with doing my own conversion was a major motivating factor for me getting involved in the professional EV industry, in the hope of making things easier for future converters!
A major aim for the project was to make an electric vehicle to break the golf-cart stereotype, i.e something with sporty performance and fun to drive. After much deliberation I chose an MX5 as the donor vehicle, being one of the lightest and smallest rear wheel drive vehicles around, and with a reputation for excellent handling.
I opted for a large DC motor as the best bang-for-buck, running direct drive (i.e no gearbox, motor coupled directly to the tailshaft) since the motor has plenty of torque. Direct drive is a great option for rear wheel drive vehicles, but you do need to run a more powerful motor and controller for good performance.
The vehicle was originally completed in mid-2008, but has since had an extensive rebuild to bring it up to date with the latest revision of NCOP standards for electric vehicles including all the latest best-practices for EV safety, as well as reverse cycle air-conditioning as a more efficient option for cabin heating.
