Re: GOM (estimated mileage) and battery degradation

Last night, I charged our 2015 Spark EV 2 LT at an EVGO station, and charged to 100%, with GOM showing 77 miles of range (50-degree temps last night). Car has been in our hands since late 2016, when we purchased it as a 178 mile demo unit. This is only the ninth time using L3/DC charging since we'v...

Re: Front tire wear

.... I wonder if driving in L all of the time could be a cause?? Slowing down at ~30 kW of Regen displayed in L is no different than slowing down with your foot on the brake and displaying ~30 kW of Regen. These cars have Blended Brakes! Tesla's do not.... I wouldn't give that a second thought. Gee...

Re: Front tire wear

... I currently have 22k miles on my 2014 Spark EV and my battery capacity is 15.4 kWh with my trend line showing a loss of 1 kWh every 4500 miles meaning I will never see 75k miles. .. I don't know how your car can be degrading at the rate.... Isn't there an owner on here that passed the 100k mile...

Re: In the market for a Spark, but concerned that it's been discontinued

That's not how battery degradation works. It peaks off after a initial substantial decline. https://ww.electrek.co/2018/04/14/tesla-battery-degradation-data/#aprd That may be true for Tesla batteries as the article mentioned and there are some Spark EV drivers who have driven more than 75k miles an...

Re: Spark EV 12 volt battery

Hey Norton! What is your current HV battery capacity? I see you have 74K miles on the car. I have just 22K on my 2014 and my current battery capacity is 15.3 kWh. What is your secret? :D I can't answer that. I haven't logged in a while because of my ~24 mile one-way commute. My routine is to plug i...

Re: Electrify America Charging Station Problems

I have followed this thread hoping some solution would be found. I saw a comment on Plugshare where someone was able to charge his Spark on an ABB charger in Albany OR recently by holding up the plug cable. I thought I'd give it a try here in Vancouver Wa. I have tried several of these chargers her...

Re: Spark EV 12 volt battery

....The other thing you may want to do is get an AGM 12 volt battery charger that also has a desulfating function. I make it a once-per-month practice to charge the 12 volt battery in both of my Spark EVs for 12 or more hours over night. I use a BatteryMINDer model 2012-AGM. Yep, I have one of thos...

Re: Spark EV 12 volt battery

Just short of 6 years old, my 2014 Spark EV's 12-volt battery quit. Car refused to shut down--kept trying to restart. Found that press-and-hold the power switch would do a hard shutdown. Got 3-4 error codes on the dash. Had to leave it overnight in a grocery store parking lot. Now that I think abou...

Re: In the market for a Spark, but concerned that it's been discontinued

I think a 5th data point should be time of year Day, Month. My tracking has shown the numbers go up when it's warm and down when its cold. I'm still not quite a year into ownership which may be the point that gives me the actual decrease in a point that can be compared to a similar time of year. Go...

Re: In the market for a Spark, but concerned that it's been discontinued

Out of curiosity, have you been "testing" the idea that maybe filling the battery to only 75-85% on a regular basis (only charge to "full" when you need it) has any effect on the battery degradation curve? I remember we sort of discussed this many months back, but can't remember if you tried it (and...
