Re: ZEVA has gone "open sorce"

Not using salvaged EV cells - I've using Boston Power Swing 5300 cells built up into 4S9P modules... Hi, its taken 6 months of waiting, but I finally have the Zeva pcbs made and now populated with the BMS and ATMega chips. Thanks very much to Ian Hooper for making this design available! I couldn't y...

Re: ZEVA has gone "open sorce"

Thanks m.art.y. I checked out the SimpBMS, but it still seemed like quite expensive option to buy the controller (around 600 euro incl shipping to NZ?) plus still need to get hold of Telsa (or other) modules. Apart from Leaf's, there aren't many other EVs at the wreckers here in NZ... only the code ...

Re: ZEVA has gone "open sorce"

Hi all, having reviewed various options for BMS for my project, this is still looking like the best (esp. for keeping my local certifier happy), if I can work around the chip shortage. Has anyone already done revised BOMs and CPLs for the other Zeva parts - 12S BMS, EVMS, Monitor, Current Sense? If ...

Re: Help Make a List of BMSs for Beginners

I'm looking at BMS options now. I'm not using OEM cells for my EV Mini conversion, I've got hold of around 10kWh of Boston Power Swing 5300 cells welded up in 4S9P configuration. I'm planning on installing in 48s 12p to give me 172V, 120A continuous (250A peak 10s) battery. Its only a little town ru...

Re: Toyota Auris and Yaris Inverter Logic board

Hi, I haven't measured anything, and am only getting stuck into my EV Mini project, using the Aqua (Prius C) Gen 3 inverter and transaxle, but from researching available info, I've come to the conclusion that the limit on the HV boost module might be around 15-19kW, with input of around 144V (nomina...

Re: Toyota/Lexus Inverter part numbers and generations

Just wondering, did anyone make any progress on looking at using the AVV50 Camry inverter? I too am curious about the differences between these and the Aqua (Prius C) inverter. I've got myself a wrecked Aqua as a donor vehicle for a classic Mini conversion. I'm initially hoping to use a fairly small...

Re: Toyota Auris and Yaris Inverter Logic board

I plan on using the Prius C (Aqua here in NZ - jap imports) transaxle and inverter in a Mini conversion. I've just obtained a wrecked Aqua, delivered today. Cost me $2k, but turns out some parts are sought after, already sold rear bumper and lights online for $400, so that helps to keep the wife hap...

Re: Project TBC (learn some stuff)

Thanks for the posts. I'm just at the research stage for my own project, looking at EV conversion of a 1974 Mini. Hoping to use a Toyota Aqua (Prius C) as a donor car, using the dual motor drive concept, as they are popping up regularly at the local damaged vehicle auctions. I wondered why, did a bi...

Re: EV build Nissan Leaf donor

Just found this thread searching online for info on Nissan Leaf donor for ev conversion. I also live in NZ (Christchurch), and am considering using a Leaf for a donor for conversion of a 1974 Mini. Where's the best places to start looking to figure out what's feasible as far as re-using the inverter...
