Hi all,
I'm new to the forum, and just getting started on a conversion project for a 2007 VW Golf. My goals for the project are to build a useful EV daily driver, with ~100km range and performance comparable to the original ICE engine, and to learn a whole lot along the way. I'm still at the planning stages, so all design options are on the table.
I have a decent background on the electronics, software, and motor control design, but relatively limited experience in the mechanics and fabrication piece, so will be leaning on some helpful friends for some advice and assistance there.
My initial plan based on conveniently web-searchable components looks like:
I can fit this into a budget that works, but don't want to spend more than I need to. I'm always open to saving money and learning more with some extra DIY, as long as it doesn't derail the project too much
.
I'd love some feedback on the big components. Will the Hyper9 motor and 4 (or 5) battery packs give the performance/range I'm aiming for, or is it under/over-designed?
My next question is around battery placement. Any suggestions on mounting the Tesla modules in a Golf Mk4 while maintaining a reasonable weight balance, and not eating into the trunk space? I'm considering 2 or 3 modules in place of the gas tank and muffler (and perhaps cutting out the spare wheel space). Before pulling the gas tank out, it's been tricky to measure how much space I'll have under there. Another 2 modules I'd plan in the engine bay.
Any suggestions are appreciated!

My initial plan based on conveniently web-searchable components looks like:
- Netgain Hyper9 AC motor and controller
- 4 or 5 x 5.3kWh Tesla battery modules (total ~91V or 114V, 232Ah)
- BMS - Orion?
- Elcon PFC2500 charger
- Adapter plate to existing 5-speed manual transmission
