My max fully charged indicated range hit a new low recently of 61 miles. This is a after a few commutes with single digit or teen F temperatures. My commute (25 mile round trip) is 90% highway (with a hill) which at 7:00 am is flowing at around 70 mph and I have the heat on... so I guess this is...

I was just surfing around and found this page http://www.a123systems.com/products-systems-energy-core-pack.htm where a123 offers a fully self contained 393 volt, 23 kwh battery with BMS/ thermal management system, that seems quite similar to the 2014 Spark EVs battery pack.

This articles seems to imply a common cell is/was used in the 2015/2016 Spark EV, Chevrolet Volt, Opel/Vauxhall Ampera, and Cadillac ELR. If that's the case ebay/junk yard Chevy Volt battery pack modules could be a very cheap source of cells...

Aren't the cells in the 2015/2016 Spark EV the same ones as in the 2016 Chevy Volt battery pack? I think the replacement cost for the Volt pack is < $4000? If this is the case couldn't you get a Volt pack and just swap the cells for far less than the cost of a Spark pack? Apparently Chevy is...

I live in CT and I very recently (~ 2 weeks ago) bought a new (never before registered ~ 100 miles on the odometer) old (2015 model year electric blue, 2LT with DCFC) from DOW Autoplex in Texas. I think I got a good deal on the price and because it was a never registered/previously owned vehicle...

That's correct any fully discharged lead acid battery has to be charged immediately because sitting in the fully discharged state results in rapid and heavy sulfation and permanent battery damage.

Sealed lead acid batteries have a self discharge rate of ~3%/month at 20C (more at greater temperatures) but there's likely some constant light load supporting various things sleep mode of the computer etc. I'm thinking of replacing the 12v lead battery with a lithium unit. I've not taken my...

Not sure what the max range of my Spark EV would be, its not been too cold yet in CT. I got this car only a week or so ago. It was an old 'new' Spark. 'Old' because it was a 2015 Model Year, (actually assembled the very end of 2014 according to the vehicle history report) 'new' because I am the...

I've only had my Spark for 6 days, and I still have temporary out of state plates on it so I haven't really opened it up yet, but somewhere in my garage I have a G-tech performance meter/gauge, I used to use years ago when I was tweaking my old ICE car, so I'll find a quiet flat stretch of...

Perhaps you have started a peak power challenge? This guy got his Spark to pull 120KW https://www.youtube.com/watch?v=AM6esfT-2rU that's 161 hp total power output (at the battery I presume)... then allowing for other minor power uses and the controller/motor efficiency it may be generating a...

I think I'll add one of those gauges, it'll be interesting to see the actual kwh used.

Thanks for the tips, already made several unnecessary trips :-).

I bought a 240 v 16 amp Duosida portable EVSE/charger from Amazon it was under $300 including the expedited shipping. I got the one with a 10-30 240 v clothes dryer plug. I'll make a few adapters so it'll work with other 240 v style sockets and the standard 120v sockets. I only brought home the...

Just parked it in the garage now I have learn all the knobs and buttons :-)

BTW You may be able to get a tax rebate on the 'charger'/EVSE http://www.ct.gov/deep/lib/deep/air/electric_vehicle/evse_fact_sheet.pdf

Will do, currently I have the 'charger'/EVSE hooked up in the garage but my Spark EV hasn't arrived yet, its still on a car carrier heading up to CT from TX. After I've used it a few times I'll let the forum know how it performs.

Looks like its an engineering masterpiece!

I ordered a 240 v 16 amp Duosida portable EV charger from Amazon it was under $300 with expedited shipping. I got the one with a 10-30 240 v dryer plug. I'll make a few adapters so it'll work with other 240 v style sockets and the standard 120v sockets. I checked out PlugShare, it looks good...

I live in Hamden, spent last weekend wiring a 240 v line to the garage. I think most of my charging will be done at home (only have a 25 mile round trip commute (into New Haven). Thanks for the charger tips, occasionally I drive down towards NYC (my other car is a hybrid Altima).

Congratulations on the purchase and the journey. I too live in CT and also just bought a 2015 2LT Spark EV with DCFC online from a dealership in Texas (not sure why they had one) its a 'new' <100 miles on the odometer never before registered car. They are shipping it to me it should arrive by...
