Are you able to drive an EV while its being charged?
I was having a good conversation with friends.
(naturally about eco-driving :thumbup:) And it brought up some good questions. Is it possible to drive an electric vehicle while it is being charged by a generator? (Not that you need too. More like a "what if" question.) I know the newer cars (Tesla/Leaf/Volt) would be a little difficult but what of the older smaller (home-made?) models? http://i.treehugger.com/files/th_ima...ctric_cars.jpg http://www.manufacturer.com/cimages/..._1k_2k_3k_.jpg |
Sure just put alternators on the wheels and charge as you drive. Kidding. I can't help myself sometimes.
AC propulsion had a generator trailer at one time called "Long Ranger" so it is possible. You could also have a pusher trailer. Neither are really good options. |
If somehow you had an extra battery pack that you used to charge the original battery pack, sure.

ok... ill make it simpler
can i start a generator in the backseat of an EV. connect the two via an extension cord. then drive around. |
I think you can. At least it better work, because I'm working on something like that right now. A 6kW generator charges a battery pack, and at the same time, the battery pack is being used by the controller. I don't have the generator yet, so it's only been tested as the charger and the controller separately.

the only reason i ask is because these topics were brought up
1. What if i run out of power in an EV? (can i plug in and continue driving?) 2. What if i want to drive father than the range will allow? (again, can i plug in and continue driving?) |
Besides the obvious downsides like the noise and the fact that you would be deaf afterwards, yeah... Why wouldn't you?
Most commercial built cars have a feature that prevents them from driving off while plugged in to an outlet, but disabling that should be easier than dealing with the generator... |

I think that would be so cool if you could get that to work !!! A DIY extended range EV would be radical !!! Does your dsPIC controller have the intelligences to start and stop the generator during the battery charging ? Is the dsPIC controller you are using DC or AC ? I hope that you continue to tell us about your success with that project. :thumbup: -Mark |

this is what i was referring to sometimes that failsafe is difficult to bypass |
I figured by now, someone would have posted a YouTube clip of just what you're talking about, aloha. But I searched high and low and came up mostly empty.
http://www.youtube.com/watch?v=0QIaUl7XcrU Keep in mind though: most EV chargers only output a fraction as much power as the car consumes while driving. A simple way to look at it: I could easily drain the ForkenSwift's (half worn out) pack by driving it non-stop at about 30 mph for 45 minutes. But then it would take ~8 hours on the charger to bring it back to 100%. So even if I had a generator powering the battery charger while driving, it would only extend my range a little bit. It wouldn't permit me to drive until its gas tank ran dry. It would extend stop & go driving proportionately more than non-stop driving though. |
