Model 3 performance vs battery charge

[Theone8181]

Hi all sorry if this has been asked (I looked but couldn't see what I wanted), but how much does the performance of the performance drop off with charge? I've seen a couple of graphs, but they look to be for the newer batteries, but mine is 2019 so I think the older style. Is it the same sort of drop off as the newer ones?

Cheers

There's a similar thread here where I posted some dyno information: Question on performance in relation to charge

Thanks. I'd actually read that thread earlier, but wondered about it translates to actual time. The reason I ask is I've put mine on charge as was around 20%, but it seemed to be pretty slow above 50 or so.

Yeah... as you can see from the graphs, power below 65-70kph isn't affected until you fall to pretty low SOC. It's above that speed that you lose the most. In terms of time... are you driving on a track? It would depend how much time you spend accelerating at high speeds.

I don't have a performance, I have a LR AWD with the Power Boost. When I do longer trips I can really start feeling the power loss at 20% SOC or so, when I need to pass on the highway.

Since you're in the UK, you might get cold days. You should know that you will lose a lot more power from a cold battery than from a low-ish SOC. On -20C days where I left the car outside and did not preheat, I have seen a maximum of 100kW of power available. That is not fast I can tell you.

I know cold kills the performance, but that might not be a bad thing if its icey . It's just general acceleration on the road where I notice it, my commute features a spot where you go on a slip road from 40 upto 70 and that's where I notice it most. Those graphs make it look like a relatively steady decline so I guess that's why it's less noticeable.
