Re: Battery degredation

Temperature in my area (San Diego, 40 miles from the beach) hit 118F a week ago on a week day. If SparkEV was sitting under hot sun, fully charged but not plugged in (ie, nagging by coworkers who complain of fully charged EV still plugged in), the battery will degrade quicker. As such, generalizing ...

Re: Bolting

I've Bolted! They're sold out of $29.8K Bolts, but they still have few $30.8K Bolts ($23.3K after fed tax credit and CA rebate) and sale lasts to Jul 2. I suspect they'll be sold out before then. But be careful of overpriced stuff stealership sneak in; I fell for it and paid several hundred extra th...

Bolting

As my 2015 SparkEV lease is ending soon, I went car shopping as I wasn't sure if I'll keep the Spark. Work is now 80 miles, making it hard on now 17 kWh SparkEV. I was looking to buy rather than lease since I wanted to have trailer hitch for bike racks and it seems all EV require some plastic cuttin...

Re: 60KW charging possible on Spark ?

I don't buy 100kW for SoulEV. I've waited for one, they tapered before 80% even using 50 kW DCFC. As for Ioniq, SparkEV is 2.6C, quicker than Ioniq. SparkEV would add 130 miles quicker than Bolt due to Bolt taper starting at 50%. Even if Bolt is only charged below 50% and average power is the same (...

Re: 60KW charging possible on Spark ?

Quick is in terms of time. When discussing battery charging, C rating should be used. In that, SparkEV battery charges at 2.4C to 2.6C. 48 kW / 18.4kWh = 2.6, even higher for some degraded batteries. No Tesla can charge to 80% in 20 minutes. In fact, some (S85 I saw plugged in at Chademo) can barely...

Re: 60KW charging possible on Spark ?

Common DCFC is supposedly capable of 500V at 125A = 62.5 kW, hence the rating of 60kW. SparkEV peak battery voltage is bit under 400V at 80%, 125A = 50kW. I've seen it show 49 kW while charging, but mostly 48kW. Current tapers down after 80% while voltage remains the same hence the power tapering. N...

Re: After 4 years, I am going to be done with my Sparks

'It gets better'.... I'm not so sure if it'll get better. If anything, things got lot worse with Bolt's release. Even just few dozen free charging Bolts clog up chargers in the whole city, and there will be tons more free charging new Leaf and i3, not to mention eGolf, FocusEV, iPace, Ioniq, Kona, ...

Re: Cold Weather Range

He said I should have switched to the 240 charger cause the charge slows down after 80% Was he driving a Leaf? I've seen some Leaf slow down to 6 kW even at 85%. Since they tend to have 6.6kW L2, switching to L2 would be no different. As others have mentioned, SparkEV charges far higher power as we...

Re: Unconventional Potential Owner

Using your financial goal, SparkEV won't be there for many more years, by which time the battery would've degraded so much as to not meet your needs in cold. Have you run the numbers assuming a beat up old car that gets 30-40 MPG? I think you can find them around $2K, though you'll need to search ca...

Re: Two identical sparks, 2 very different range estimates..

I find it interesting that the 2014 has a 21kwh battery and the 2016 has a 19kwh, yet the useable capacity is almost the same. Strange GM would do it that way. That's because 2014 is 3 to 4 years older and has correspondingly higher battery degradation. New 2014 would have much higher capacity than...
