Pack swapping would be expensive -- you'd need at least 2x the packs. You also still need some way to charge the packs. If you do a dump pack, even if your dump pack is lead acid, that's still a significant expense and a lot of weight.
If the vehicle has regenerative braking, you can do tow regen with a truck. I have done this, it was fun to get hundreds of charging Amps ( http://explodingdinosaurs.com/9electric/2009saltflats ) . If your regen is stout enough, this will easily be much more power than any charger you plug in. ----- Original Message ----- From: James Massey Sent: 07/18/13 10:00 PM To: Electric Vehicle Discussion List Subject: Re: [EVDL] Targa racing ... The race includes refueling stops and tour stages as well as the race stages, so swapping should be able to be done in a leisurely manner, rather than a "pitstop" style. The commercial battery swap systems for forklifts and similar are likely to be too heavy and not appropriate for mobile set-up (at least the few I've seen). Bruce suggests dump charging, which may be an option, so we'll see. Bruce also asks "how much performance?", which I don't know at this stage. I feel a back-seat area box, if possible to go sideways out, may be best for weight distribution, constraint and access, but they already have the roll cage in, and a level of plans that may need to be worked in with. As I understand it, a standard Tesla did the "Rookie" Targa event in 2011, which is shortened, I don't even know if they are planning to do the "Rookie" or main event. At present they asked me to assist with the EV parts of the build, and I know very little about the rest of their plans, so I'm ga thering ideas before I go and meet up with them at the car some time in the next week or two. ... -------------- next part -------------- An HTML attachment was scrubbed...
