While you should avoid charging at all if the battery temp is 7 bars/60% or higher, I agree that L-1 usually produces less battery heat. My GUESS is that it adds heat at about the same rate the pack radiates it away.danrjones wrote:This will be interesting in July.
Last night at 10pm it was 80f and the battery temp was smack in the middle,
lvl 1 charged all night, 60f this morning at 6am, and the battery temp was down a couple chunks (not sure if its bars, all I see is a constant bar left to right)
But in July when its 105 at 10pm and 78 at 6am, I'm wondering if lvl 1 charging all night (8 hrs) or lvl 2 charging for say 2 hours (4am to 6am) will end up thermally better / worse.
I guess I can try both and see.
I had to write this out. I comparedlorenfb wrote:Remember, during any charge mode (L1/L2/L3) the battery voltage is basically the same, approx. 370 - 400. During L1/L2 the EVSE output voltage is changed (scaled) by the inverter to the 370 - 400. For L3, The DC source is in the same D.C. range.lorenfb wrote:SageBrush wrote: hmmm...
L2 may be twice the current but it is also twice the voltage so
T2 = 0.25 of T1You can adjust the numbers based the actual L1 versus L2 currents and times.
The most logical explanation for Hx is that it's the ratio of the present battery conductance (inverse of resistance) to thedanrjones wrote: I also noticed today my Hx jumped up by a full 0.1. SOH stayed the same so far today.
Reading through the threads here I have discovered Hx was the old battery health meter before SOH was created / discovered.
There didn't seem to be a consensus for what it mean now, especially for the 2018's.
