New LFP battery manufacturer recommendations

[ChehRob]

The advantage of LFP batteries is, as I understand it, that they take charging up to 100% without any problems, including level 3 chargers. They last a long time. They are said less likely to burn, they are cheaper, they use cheaper materials. And once the US charging network is built out on Federal and most State Highway systems 250 real miles of range will be adequate.

All true.

Also heavier and slower and less efficient.

They serve a purpose and fill a niche. Perfect battery for a base model.

Mach1E - my only disagreement is that with a well built out level 2 charging network 250 real miles of range will serve almost everyone well. Even when traveling by myself on a long road trip I like to stop about every three hours. Ten years ago - 4 hours. Age has its effect. LOL

I think that one issue some people would see is the inability of this technology to sustain high output rates, making it a poor choice for the high-performance variant. As @Mach1E said, a base model would be a great home for it. It would thrive there. The GT would be a lousy place.

The GOM was very optimistic with my LFP range this morning. I must be babying the pedal recently.

It's about a month since we got our 2023.5 LFP Premium STD. We're not babying it but our commuting doesn't push the car hard, this morning had the highest estimate we've seen.

Level 2? Are your stops usually 7 hours long?

hmmm I wonder... even in the GT, the discharge rate with your foot on the floor is less than 5C. That is not real high and with 4 cells in parallel (with the LR packs) you are around 1C per series max.

I bet weight and size will be the killer. Adding a few hundred pounds is not good for performance.

I meant to say Level 3

There’s no reason that the GOM should be any better due to LFP.

250 miles of range is not 250 miles of highway range. You can subtract 15-20% if you drive 75-80 mph, and another 15-20% in the winter. And you never stop to charge at 0%, you stop at 10% or more. And due to charging speed you rarely charge past 80% unless you want to wait an hour (which I have done, BTW). So you can knock off another 30% for your charging stop range.

We have a ways to go before BEVs are good road trip cars. I know those who like adventure, or those who are retired and not in a hurry, find road tripping in a BEV to be fine. Not me. Not my wife. I like to drive my car so I do it, but my wife refuses to take my car on trips now. Too many unpleasant experiences at charging stops.

250 miles on the GOM is not 250 miles of rage. FIFY

No disagreement here. But when I talk about 250 mile range I mean real range. which likely means EPA 300. Should I get a 300 EPA range EV my first two years will be carefully chosen to ensure charging availability. I am expecting a decent charging network after 2025.

The charging network for my MME will get 10x better as soon as the Tesla SC adapter becomes available next Spring.
