Re: Winter, hilltop reserve, and battery conditioning

Lots of cold weather data since last post has confirmed that the conditioning period is a variable that gets more frequent when it gets colder and the energy used per cycle increases in proportion to how cold it was. After the cold weather for the last couple of weeks my hilltop reserve range had dr...

Re: New tech battery for our 2017 bolts in the future?

If we want to save the future by reducing energy consumption we will need to build cars that live for a long time https://www.theguardian.com/environment/green-living-blog/2010/sep/23/carbon-footprint-new-car An EV is so simple in comparison to an ICE that with little added cost in stainless hardwar...

New tech battery for our 2017 bolts in the future?

I just sold my 2000 Honda insight after 17 years of ownership Brake lines, gas lines, steel suspension components, rusted bolts, and mice attacks But like electric cars the batteries are the weak link. Honda never offered a lithium pack to replace the very custom Nimh stock pack. So the old insights...

Re: Winter, hilltop reserve, and battery conditioning

Have been watching the battery temperature conditioning via the juicebox data logging. Some observations: The energy used for each warm up cycle is ambient temperature dependant When it was 30f it took about .8kwh per heater cycle When in the 20f range I saw as much as 1.37 kwh The frequency of cond...

Re: Of grid solar charging

Happy to see I’m not alone in feeling that the huge 60kwh battery in the Bolt may make a great place to dump excess solar production. We are going through a spell of weather that Is mostly cloudy so my 7500w solar array is struggling to keep my 48kwh lead acid storagebank filled Each day so EV charg...

Re: Winter, hilltop reserve, and battery conditioning

The % of energy used for conditioning is a true % of energy used up to that point relative to total energy used to that point. I unplugged the evse with the battery full to the hilltop reserve but not finished the conditioning the circle graph indicated100% energy was battery conditioning and the dr...

Re: Winter, hilltop reserve, and battery conditioning

Ok have some data points At ambient of ~ 20 degrees f Conditioning used ~ 1kwh/ 6 hours of sitting http://99mpg.com/blog/finally-i-have-an-electric-car-chevy-bolt/ I expect it works the same when not plugged in Not as bad as I had anticipated. The in car energy graph showed no battery conditioning ,...

Re: Winter, hilltop reserve, and battery conditioning

Well it looks like we will learn about cold battery conditioning first hand Friday night is supposed to get down to 13 f and Saturday night to 19 f This morning it was 29 and I saw no battery conditioning ? My evse datalogs each charge so it should clearly show if it needs conditioning and how much....
