When I bought the 1989 Toyota MR2 that was to become MR02EV, it was pretty un-loved. Especially the wheels which had been painted with white house paint. I could have refurbished them, but I never did like the originals so started looking for alternatives, which started a minor obsession with wheels and conflict with my Wife (cars can do that)!
Motor controllers for electric vehicles like the TIM600 in MR02EV typically have a large internal capacitor bank on their input with very low Equivalent Series Resistance(ESR). As such they require inrush protection when first powering up to prevent a large current spike which can damage components – most commonly, welding contactors shut or blowing fuses.
In MR02EV I use a ZEVA Smart Precharger which is designed with a 2-stage soft start to limit inrush current via a resistive circuit that charges up the inverters internal capacitors before automatically closing the main contactor when the process is complete.
Every gas vehicle on the market uses a belt driven alternator to generate 12 Volts DC to run the accessories (fans, pumps, headlights, heaters, etc). MR02EV has no alternator so a Chennic DC-DC converter is used to convert the 370 Volt main battery pack voltage to 12 Volts.
I have a Degree in Electrical Engineering from the University of Technology Sydney and am employed in Broadcast Television Industry. My hobby is the (continuing) modification of MR02EV. I am also the National Treasurer of the Australian Electric Vehicle Association.
