Ann: Extra Fast Charge Batteries - Potential Game Changer, page-167

LOL the c4v efc program.

A made up abbreviation for what the rest of the industry calls XFC.

No one uses the abbreviation efc
Just like bmlmmmbpp battery.
If you make up a new name, maybe someone will believe it's true?

The 6 minute to 85% charge whizzo battery has now morphed into a 20 minute charge or is it longer? Not so fast. Just normal ho hum.
Gone the way of the solid state battery.
Remember that one?
I'm surprised they are not trying to suggest the P-series (what is it with these people p series?) is a solid state battery.
It sure as hell ain't no XFC battery. Read the im3ny battery spec.....

That 6 minute to 85% charge battery was supposed to feature in the mythical (imo) Nyserda funded program to put one in a NY city bus.
Gone quiet on that one. And gone quiet on the solid state battery etc etc.
Smoke and mirrors imo.....
