Before I buy an EV I need to know if a gasser truck or auto can jump start an EV. How about a lithium power pack for jump starting.
Just read this in the news. Interesting

Jump starting doesn't work for EVs. A jump start simply means you give a battery power boost in order to start the ICE which then charge the starting battery via the alternator. You just need a quick burst of electricity to get the ICE running then the ICE does the rest.
With an EV, there is no ICE. A quick burst of electricity does no good. You have to actually recharge the battery which takes time.
As for the article, it's non news. I'm sure ICE vehicles have broken down around there also. Sure the coal workers were nice and helped out but I bet workers at an electrical power station have helped folks broken down in ICE vehicles without it being a big news item.

I'll add that this obsession with turning any and every electric vehicle that runs out of juice into some sort of "oh the humanity" story is getting tiresome. People have been running out of gas/diesel on the road for over a hundred years now. You get a tow or a few gallons of fuel (or a quick charge) and move on.

I recall reading that Tesla's maybe not the current models, had to be flatbedded back to a Tesla shop if the battery was flatlined. They could not be recharged in the field.

If the jump start means the 12v accessory battery has an issue then absolutely the EV can be jump started. Very little power is needed to get the computer on and functioning to drive the vehicle. Even a weak pair of cables or the smallest half depleted jump box can do this.
If the main traction battery is depleted you will need a gallon of gasoline and a 2500 watt generator and 30 to 60 minutes to get a few miles in. But just like a gasoline vehicle the EV will be giving plenty of warnings in advance to adjust your route to a charging station. But if you deliberately want to run out of fuel the EV will eventually quit just like a gasoline vehicle. This would be considered driver error, not a reflection on the vehicle.

No. No problem charging in the field even if driven to (and past) zero percent. Lots of people do “run to zero” tests to see how far past zero an electric car will go. Triple A units have modular 4 to 8 kWh lithium packs they use to “jump” them but it’s not like jumping a 12 volt battery. It’s typically a 15 to 20 minute process. Or a generator would work. About the same time although less of a charge than the Lithium portable pack as they use a CCS or Chademo connection with them. I
The instrumentation is very good on EV’s. You would have to work very hard and deliberately to kill a battery in an EV. Or be dumb as a post.
Slightly off topic Bjorn from Norway did a test on our model Y. The car went for 33 kilometres after the battery read zero percent.
On the Coquihala highway between the Okanagan valley and Vancouver (abiut 450 kilometres) about 7 people per weekend run out of gas and BCAA has to rescue them. Never makes the news. But if an electric car someday runs out of power on that stretch you can be guaranteed it will be international news. ![[emoticon]](http://www.rv.net/sharedcontent/cfb/images/smile.gif "smile") .

Sounds like the answer is yes if AAA has the proper items. I found the photo in the news article to be funny. Don't be so sensitive all the time sports.

QUESTION.
Could a dead car be towed “wheels down” for a few miles to charge the battery much like an electric bike coasting down hill?

An EV jump start = a portable generator and about an hour's worth of charge.. Or tow it to a re-charge station. A traditional "Jump start" wont work.
IF you want to drive way more than your range. Carry a portable generator on a cargo tray (hitch mounted you do not want it INSIDE the vehicle)(
Home was where I park it. but alas the.

Run out of juice in DC and see how long it takes to find six volunteers to push your ev a half mile to a charging station. You'll find six willing to take it to a chop shop, or six willing to study it for a year to find a way to subsidize longer extension cords, but to actually voluntarily help you? Naaah, get real.
