Re: [EVDL] Leaf battery pack overheating due to depth of discharge.

2017-06-21 Thread Tom Parker via EV 
Lawrence, 

Is this a 30kWh leaf? 

We've seen that they will accept charge much faster than the 24kWh leaves, 
maintaining 50kW for most of the charge to 80%. This will put a lot more I^2R 
heating into the battery than charging slower. The 24kWh cars average under 
25kW for a charge to 80%.

How hot is 5 and 9 bars?

hasn't exceeded 6 bars. This is in hotter temperature than yesterday.  So 
ambient temperature doesn't seem a big factor. It is large depth of discharge

Re: [EVDL] Leaf battery pack overheating due to depth of discharge.

2017-06-21 Thread Cor van de Water via EV 
I typically see the temperature bars vary from 4 on cold days to 6 on hot days, 
due to the ambient temp alone.
I made a note of a Fast Charge with LeafSpy reporting a rise of about 10 deg C 
in pack temp when charging from
SoC 40% to 90%.
I suspect that your pack was already warming up due to long-term drawing 
current from a depleting pack,
especially as low as you got it, then fast-charging it back up from that low 
point. Good to know.
Did you record the actual reported temps (LeafSpy) or only the display bars?
Cor.

After driving 135 miles down to 13% charging back up to 85% caused the pack to 
go from 6 bars to 9.  Today the plan is to try to stay above 50%.  So far so 
good.  The pack hasn't exceeded 6 bars. This is in hotter temperature than 
yesterday.  So ambient temperature doesn't seem a big factor. It is large depth 
of discharge then a fast charge.  Now in Santa Barbara.  Going to Rancho Jarupa
