Loading speed of what? But yes, a lot of improvements can be made with software.
I believe the MME allows up to 150Kwh charging speed. And I wonder if this can be improved and increased with OTA update.

The charging curve is much more important than the peak charging speed, and yes Ford has said they will be improving the charging curve with an OTA update.

The max speed is based on EA chargers which are 450A max current (170kW ish max theoretical at 80% SoC).

The curve of when it slows down is a different story.

I really, really hope they do this. Seeing how fast the Audis and Taycans charge is crazy.

Taycan is 800V, not 400V, so there is no way to get to that level. On 400V, 200KW is max charging you can get.

Well it would be nice to get sustained speeds of 200kw while DCFC…

There are tons of different physical standards for ethernet. The earliest versions of ethernet was running on a shared coaxial cable similar to cable TV cable, which is two wires. After that there was 4 wire RJ45 connectors on twisted pair cable, which was extended to 8 wires (4 wires each direction) when 1Gb was being used. Later there was a standard for 4 wire 1Gb, which nobody seems to pick up. Then there are twinax cables (4 wires, one twinax cable for each direction). There are optical fiber standards with 1 fibre or a pair of fibre (one for each direction).

Still, even if using the 4 wire RJ45, if running in half duplex it basically 2 and 2 wires of the 4 having the same signal, so it could use only two wires if the interfaces had physically connected both receiver and tranciever on the same wires (like the coax).

.. so using two wires does not mean it is not ethernet, or that it is a custom version of ethernet, it is just ethernet, but not the fastest standard

https://en.wikipedia.org/wiki/Fast_Ethernet#100BASE-T1

Fast ethernet = 100Mbit. 100Mbit ethernet is very commonly used in embedded systems because it is cheap and reliable and can run on cheap cables.

Have you ever actually run ethernet over coax? It SUUUUUUUUCKED.

Don't miss that at all!

Anyone remember the odd “taps” you’d have to put into the big Orange cable that you’d use to connect?
