Tesla Model 3 - V3.0

Neither seems to take into account transmission loss there. There is no way of telling what your usable battery is by deriving from the above - it's literally impossible.

A battery diagnostic tool is required. I knew something was off because on a full days driving my used energy was maxing out at 51kWh.

There is a hard coded buffer built into the LFP battery of about 2.5~3kWh. This can never be accessed by the vehicle. So the absolute max usable capacity will be 57.5kWh. So the max that 100% to 0% can possible be is 57.5kWh in these packs. But that assumes a zero buffer which again is not happening.

The buffer in any earlier 2022 RWD's was about 2.5kWh meaning usable battery was about 55kWh.

However many of the RWD's that landed in september 2022 have a buffer of 5.5~6kWh which reduces the usable battery to max 52kWh.

People on here don't seem to believe that for some reason and good luck to them. If you have received a September car with a lower buffer then well done, you got the car as advertised.

For anyone with the massive 6kWh buffer then you were kind of screwed..............

What diagnostic equipment were you using to get the output figure of 51kwh?

So it was the cars system saying this since thats the only thing the Tesla guy can see. Interesting the difference in that and the amount they are telling us is being put in on the app. Especially since someone said what was taken in matched what their charger said. I know there is always loss but that seems like a big one.

what sort of kWh is your car taking in and at what % to get to 100%?

Someone here trying to flip their car straight after collecting?

Done my first big drive today. Went from 100% and used 34kWh, leaving 33% left. Back of the envelope calculation gives useable battery of 52kWh.

i feel sure that Tesla will have quoted correct WLTP. It is usual that a certain % of battery energy is kept in reserve (common with all EV's), however that just means that when battery is depleted to this buffer level the car registers as 0% (0 km's) but the battery still has available power that can be accessed and used to drive/increase range. It seems a prudent measure adopted by Tesla in their BMS to discourage drivers from overly relying on this with attendant consequences, risk, dangers and long term maximising battery health.

For anyone who is interested I am attaching a link from a well regarded expert who has tested and demonstrated this with an LFP Tesla battery with real time "Scan my Tesla" side by side which shows the buffer. The objective was to drive to 0% and 0 kms but to keep driving until the car eventually stopped. When the car registers 0% you will see that he was able to drive another 33.7 km's Clearly this is not recommended but does (for me anyway) clarify the need for a buffer and why it is incorporated. We all can have views as to the size of this buffer but I think it may help with understanding.

My car is a March 2022 RWD with the nominal 60kWh LFP battery. On most cars I can obtain WLTP range with a little care, ie drive like a granny with no heat/aircon ☺️ but it appears to be easier on the Tesla than other EVs we have had. Last week did about 1K in UK, some fast some slow, rarely saw less than 4kms/% sometimes 5kms/%.

Basically what I am saying is I don't really care what the usable battery is, the range is great.. (Provided the usable battery hasn't been changed.)

I got the suitcases down from the attic yesterday to see what would and wouldn't fit in the boot of the model 3. I was very impressed.

My last car had a cavernous boot and we were spoiled for luggage room when going away.

Anyway, the boot of the Model 3 took : 2 x large (check-in) suitcases and 3 x small suitcases (carry-on). One of the 3 smaller cases fit very easily in the storage area under the 'floor' of the boot.

This saves me the hassle of needing to buy a set of roof bard for a roofbox which is great.

First big spin yesterday. From Dublin to Galway and back.

Car is lovely on the road and love the cruise control.

Autopilot was very jittery on the m4, especially any time we came near a turn off,it would start to steer for the middle point of the off ramp and the current lane then pull back to the current lane.

Admittedly the lines on the road need new paint in places but is this others experience of AP?

Of course - I didn't use this as I was keeping it for cables, first aid and puncture repair kit etc.... but yes, this would also home a decent sized rucksack if required.

"AP will improve the more you drive". I feel that AP2 got worse during my time with Slughorn (my old model X).

AP3 now in Lady Grey (2022 m3 RWD) is still less good than AP1/Highway Autopilot was in Severus. Removing radar was a huge step back. I feel that AP3 in a loaner raven S I had in 2020 was better than it is now.

Also the new follow gap being limited to 2 instead of 1 is way too far away

Agree with all the above. New "tesla vision" is blind. Or at least has some serious cataracts

Have tried a few phones of different sizes from an 8 which is nearly identical size wise to the mini up to a pro max (all iPhones) with no issues, one thing to watch out for is optimised charging, if you are at 80% it may not charge you can turn it off in battery settings
