A 50C(!!) battery is a very different beast than a laptop or a cell phone that discharges over the period of a few hours. Honestly, I think this is a rather bad idea. Even high performance EVs don't slam batteries that hard. Here's an example of what very high discharge does to RC batteries (there's many others on Youtube I'm sure): https://www.youtube.com/watch?v=-46h7Hshl2c
You'll be getting into serious discussions about thermal management and wire resistance, resistance of other components in the system, etc. You won't be able to just switch it with a simple relay/FET arrangement, you'll need a proper EV level contactor (which itself is rather large, power hungry, and expensive). If you need to provide high power, it's /much/ better to just up-size your battery to give it a gentler discharge. -- Sent from: http://electric-vehicle-discussion-list.413529.n4.nabble.com/ _______________________________________________ UNSUBSCRIBE: http://www.evdl.org/help/index.html#usub ARCHIVE: http://www.evdl.org/archive/index.html INFO: http://lists.evdl.org/listinfo.cgi/ev-evdl.org Please discuss EV drag racing at NEDRA (http://groups.yahoo.com/group/NEDRA) -------------- next part -------------- An HTML attachment was scrubbed...
