Sow, kwam nou toch iets aparts tegen op internet:
Converting my Starlet to electric drive involved housing the batteries,
installing an electric motor, new electrical system,
break vacuum system, and safety features.
BatteryI selected 12 T-875 Trojan deep cycle flooded lead acid batteries. Why flooded and not sealed? Flooded batteries offer substantially superior performance and life span. Sealed batteries however fade faster and have a shorter life span.
Battery weight is key and to get a four passenger EV I had to sacrifice some range and performance (see final specs below) .
MotorThe 8" Advanced DC motor was selected because when coupled with the 96volt electrical system it offers 40kw of peak power and while this it does not give Ferrari like performance it helps make new car an excellent four passenger suburban run-about.
ElectricalFor safety and ease of servicing the major electrical components are housed inside a tough weatherproof case. In addition, I included motor over rev protection, an inertial cut off switch and inertia switch.
BrakesWithout the IC engine the break system needs another means to create the vacuum that assists the vehicle to stop. In my electric Starlet this vacuum is created by adding a vacuum pump system.
Eindresultaat
My electric Starlet includes an number of safety features such as a fully enclosed (bolted down) battery box and cover, inertial power cut of switch in case of a bad impact and safety covers for all the key electrical systems.
ChargingThe fuel cover retains its original function. I just pop it open and plug it in. A 15 Amp cable is ideal but when on the road I carry a 25 metre heavy duty 10Amp cable so that I can plug in and power up from any household 240v power point.
Power consumption is minimal. A full charge for the Starlet is around 14 Kwh. That's just 70cents when using off peak power or about 1 cent per klm.
