2014 Battery Stats

[jt123]

22 Feb 2018. 2014SL. ~49000km. 100 SOH, 97.77 HX. 24 QC and 2111 L1/L2. Montreal, QC.

We got the car in late 2017 and SOH was 94%. Previous owner did mostly L2 charging. A few things that happened after getting it:

1.) we took a deep discharge until --- the first day we got it, not intentionally.
2.) the car is parked outside, and we've had some really cold days this winter (nearly a week straight of -16C or lower, hitting -25 a few times)
3.) mostly L2 charging and keeping the SOC between 20% and 80%, topping up to 100% once a week or two for a full balance.

Not sure which of the above, if any, had an effect on the rising SOH.

Will see how the health is after this summer.

My 2014 S lost the first bar after 53 months and 37.5k miles. AHr = 55.29, SOH 84.54, Hx 79.86. AHr is continuously dropping at ~1.5/yr rate (about 3% SOH/yr).

The car lives in a climate where temperature goes above 90F regularly during summer, but has a real winter (15-20F).
