Description:After several years of dreaming and several months of research and collecting parts, I purchased a 1987 Suzuki Mighty Boy with a view to converting it to run on electricity. This car was chosen because it was cheap, it is a ute, so batteries could be mounted in the tray, and it is very small and therefore relatively inexpensive to convert.
The old petrol engine came out on 21 June, 2004. The new motor is an Advanced DC 8 inch series wound DC model. Its 100- year-old technology, but simple and reliable for the first-timer. These motors are made in the USA especially for electric conversions. It is a fairly powerful engine for such a small car. There is 45kW of power available at the wheels. The original petrol engine was rated at just 18kW peak!
The motor needs a speed controller which connects to the accelerator pedal. A Curtis 1231C8601 500A model was chosen. These have a reliable reputation and run at 144 Volt nominal. No regeneration is available currently, but I will work on that later.
The vehicle originally had a lead acid battery pack, but this was soon replaced with 45x 90Ah ThunderSky (LiFePO4) lithium batteries, which doubled the range from around half the weight in batteries. |  | Summary:Technical Specifications- Motor: Advanced DC 8
