Don't know if this is the best part of the forum for this but...
Copied and pasted from my rant post of Speakev.com
I retrospect I've been looking at ways to not be reliant on the rapid chargers. The was a chap from Metric mind in the US who put 3 Brusa chargers boosting his 3.3kw output of his 2011 leaf to 13kw needing not direct interface to the can network. He did a really nice job but not cheap. About £3-4k. Brusa now make a 22kw charger too, so that's also another expensive option.
Now, I wont do the following for several reasons. But... it is possible to buy very cheaply 12v server power supplies or ever 51.4v ones. which could be put in series to get higher voltages (if they have the DC grounds severed on all but one). (a lot of diy ebikers use such a setup to charge big packs) I have worked out you could use 5 or 6 server power supplies, link each to an 80v capable DCDC boost and the series the outputs to get near the voltage required by a Nissan LEAF. Then you might be able to use these instead of the purpose built Brusas. This however is forgetting all the safety concerns with High voltage and using things for which they were not initially designed, plus putting a lot of faith in cheaply built electronics
Has anyone done anything like this. Is there a reason that this might not be possible. Or advices to increase the safety of doing such a thing.
