I've been reading through the forums and trying to get up to speed on these vehicles. I apologize if I am asking a question already answered. I am considering buying a Chevy Spark EV with 22k miles. I'm on the week long Carvana trial. The vehicle arrived from NJ with only 20% battery. I've since charged it up and drove it all the way down several times. However, I am only getting 55-60 miles. I understand driving styles can affect this. However, even with temp control off I'm still not able to get more than 60 miles. And, perhaps more troubling. It's only taking 7 or so hours at 12 amps 120v to get back to a full charge. My understanding was that this should take 20 hours.
My concern is that somehow the battery range has been diminished. Perhaps through the cold in NJ? Or bad treatment? I don't know. Would the range and quick charge times be a red flag for you?
Really love the car though. It's a robin's egg blue with the two tone blue/black interior. Everybody here would like to keep it but I don't know what to think about this battery situation.
Also, I bought a Kindle Fire to be able to run Torque Pro via a bluetooth obd reader. But, apparently I have to perform some tricks on the Fire to access the Android store. Fortunately I don't have to root it.
Oh, and it has what appears to be new Bridgestone Ecopia EP150 tires on it. Which makes me wonder if it has been driven hard to have to replace the tires at 22K?
Anyway, any advise or suggestions would be greatly appreciated.
My first Spark EV was a silver 2015 2LT. At 24k miles my "calculated" battery capacity was 15.8 kWh. You can use the data on the Energy Information screen in the car to estimate you current HV battery as follows:
1. Charge the car to 100% (it quits charging and the green light on the dash goes off.)
2. Go to the energy information screen and reset all of the data to zero. Make sure the KWh used is zero too (it is automatically reset to zero when the car is fully charged)
3. Take the car out for a 40 to 50 mile drive and try to maintain a steady and constant speed. Avoid hills, head winds and tail winds. Make sure you are driving in D (not L).
4. When you return home, total up the usage percentages for Drive, Climate and Battery.
5. Note the kWh used number. Divide the kWh used number by the total of the percentages in step 4. Then multiply by 100.
This will give you a rough estimate of your battery capacity. The number will become more accurate the further you drive. Just don't run out of juice!!
I collected over 160 data points this way and it gave me a very good idea of the battery capacity and degradation rate for my 2015 Spark EV. I started using Torque Pro just after my lease ended. I now have a 2014 Spark EV 2LT and a 2016 Spark EV 2LT and I use Torque Pro to pull the data from the car's computer.
Note: I also tried to install Torque Pro on as Kindle Fire. It didn't work - something about the Android used in the Fire. I was successful in installing Troque Pro on an old Nexus 7 tablet I have. Now I have it installed on my Motorola phone.
