Now that most of the Car Manufacturers are producing Electric Vehicles I have been wondering what the effect of a "Quick Charge" has on lithium batteries. How long does it take a charging station to fully charge a lithium battery and just as importantly are there any negative effects on the life of a battery system/pack using a quick charge? My understanding is that a quick charge only restores about 40% of the charge while a full charge takes several hours.

It seems that this information is rarely, if ever discussed during the initial vehicle purchase, just wondered if there is a reason. I doubt that most consumers would ever ask or know why.

One of our neighbors recently purchased a EV truck that he planned on using to tow his boat, he didn't get very far before the batteries lost their charge. Not happy.

Average gas powered car takes 5 minutes to fill up and then good for 400 miles or so. Plus there are gas stations every where.

Until electric vehicles get to that type efficiency and convenience of filling then they are just not feasible no matter how much Government pushes them.

Your question about fast charge is a good one. Typical batteries will last a very long time if you keep a small trickle charge on them and do not drain them down to low or charge them too fast.

I would assume the Lithium type or what ever batteries they are using in the cars is similar. Harder you work them shorter the life expectancy.

Now the reason they do not talk about that at dealership is they probably do not want to run off customers.

It's like anything else, EV's have their place (like needing a hammer or a wheel barrow)
ie. people that don't have to travel, don't work or work close to home, etc.
EV's are NOT made to travel long distances.
Example here:

We just drove from CT to MI (US 131 race track) and back 2 different routes (90 and 80) we did not see ONE charging station in either direction.

Not to mention the dangers of the batteries burning up while charging ie.

I can see EV owners "verify that all cells in your battery packs are balanced prior to charging".

Just make sure you have PLENTY of Hot Dogs and Marshmallows so when your car burns up you have something to do since the fire departments will NOT try to put it out.

Bob, I think fast charge in that case is a misnomer. I believe short charge would be more correct but then people would understand what is happening and it wouldn't sound as enticing.

On another note, I don't know how many here heard that an electric JR dragster caught fire at the WCF in Ardmore.

Tell your friend to keep it out of his garage...





And it wasn't even being charge, scary.

I think you are right and NHRA came out with a statement soon after saying something like the EV's must not be inside a trailer while charging and they must not be left unattended while charging. Something like that. I did not pay too much attention to it because I know I will never race EV in NHRA.

I would assume that much like RC car Lipo batteries. charging a cell to fast or over charging it, can cause it to expand and/or combust. I would think that fast charging probably doesnt give a true full charge because it doesnt give the cells time to balance charge. In RC cars there is no cell management to correct that while in motion while I'm sure the cars have on board cell management to balance the cells after a fast charge.
