michaelmurfy: @jonathan18 that’s more of an estimate but you can do a proper test from the service menu if you’re keen on seeing. As your car has a LFP battery you need to charge it to 100% every week.
Mine - which is a NCA battery being a long range model 3 is sitting at 96% in Tessie which sounds about right. I have not done a full test from the service menu. I’m up to 38,000km too.
Thanks, @michaelmurfy - I remember reading this test was available but hadn’t dug anymore into it. Doing so now it refers to a need for it to be plugged into a ‘level two’ charger. I see references to that meaning one using 240v, but assume that they’re talking in the US context where a ‘level one’ charger is 120v, and level two would be more like a ‘fast’ 240v 7.4kW unit as opposed to the basic UMC I use. I wonder if our 16A caravan charger would be adequate?
My understanding is the encouragement to charge weekly to 100% is more about keeping the BMS happy, rather than about it being necessary to actually manage/minimise degradation. Earlier this year I did exactly that - let it run down over the week and then charge fully once - for a number of weeks but this did didly to the stats.
As I rarely need the full range it’s not something I panic over; I imagine it’ll be many years before degradation has a real-world impact.
Anyway, back to s/h Model 3s - can anyone confirm when NZ-new M3s started shipping with LFP batteries?
Is $45k a realistic price to pay for an LFP-era model? I’ve read some suggesting s/h prices will drop once the Highland refresh is released - does that have any substance to it? We had also previously talked about waiting for the ‘M2’ to be released, but I’ve not heard anything more about this in ages…
