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 ,...

My evse datalogs each charge so it should clearly show if it needs conditioning and how much....

Re: Do you think I'll be able to tow a small boat with the Bolt?

Stray sunlight did effect the system
The CDS cells are not linear and absorb light from a wide acceptance angle, both of which make them a poor choice for this detection
Have some directional photo transistors on order which should work much better.

Re: Winter, hilltop reserve, and battery conditioning

Thanks for the real world experience positronic Have not seen a miles/ kwh hit from the cold yet No battery conditioning yet. On a 38 degree morning I noticed what seemed to be a reduced max kwh into the motor and lower than normal acceleration rate? Lithium Batterys gradually loose their high drain...

Re: Of grid solar charging

The juicebox pro40 Can be set to any charge rate with the phone app So in theory my phone could adjust the rate based on the solar availability The car accepts that rate and will charge accordingly Only issue is that the rate of charging seems to be negotiated when the evse is attached and will not ...

Re: Do you think I'll be able to tow a small boat with the Bolt?

It worked surprisingly well in my initial testing. http://99mpg.com/blog/finally-i-have-an-electric-car-chevy-bolt I just taped the sensors onto the appropreate lights with black tape and adjusted the on off threshold and it worked perfectly The circuit has a single quad op amp Some connectors 4 pot...
