Ok, been lurking for a bit, and *maybe* thinking of diving into an EV conversion.
Have a reasonable idea of what I want, but wanna do it cheap, well maybe not as cheap as ForkenSwift, but I hope you get the idea!
I'm not expecting much, but thinking of a small Japanese hatch. Daihatsu/Honda/Subaru or similar, with a minimum of two seats. (<1000kg, tare)
Reasonable acceleration, around 70-75 kph top speed, and a range of around 50km.
Looking to build an around town runabout/grocery getter/kids pickerupperer. Well, maybe 4 seats would be better!
Here is what I'm thinking so far, so I hope I'm on the right track!
Possibly 72 volts, 250-500A controller, 6.7" ADC motor (or similar).
Batteries, well, I haven't got much of a clue! Maybe something deep cycle around 85 AHr? Was thinking LiFePo4, but probably a wee bit expensive, I do love them on my e-bike though! I'm just a bit confused on all the differenet types/styles of lead batteries, and their suitability for an EV!
Just concerned if I go lead, then weight, voltage sag, and Peukerts will all be isssues limiting range and performance.
And at around $2000 AU or more for lead, what sort of lifespan can I expect?
Lets say I can keep 90% of my trips to <50% DOD. Do I think of lifespan in terms of cycles? year(s)? months?
And bear in mind that there will probably be two drivers, and she drives more than me!
And is probably not as savvy.
I dunno, maybe its just me, but is the Wiki just a little short on facts/examples that would really get noobs started on the right track?
Would really like to collect as much info, so I know pretty much what I need before
Be nice to have some sort of chart that would give a pretty good idea of performance/range for different voltages/battery packs.
i.e. car x @ 72v will do x kph with xAHr of lead, with x km range.
car x @ 120v will do x kph etc, etc.
