Anybody have a solution to get rid of the max 5sec power cut off

[jonkMACHE]

Electric motors have been around for a long time... I know the Tesla lovers think Elon put some sort of magic in theirs, but truly, there's nothing really revolutionary about them. The technology to package everything in a reliable car with a ~300mi range is revolutionary, but not the motor.

You get an electric motor to accelerate faster by drawing more current through it... the question is, can the motor manage that current, and handle the stress of it repeatedly pulling that current, and can the supporting parts (in Ford's case the HVBJB) handle the electrical stress without melting down.

I appreciate you speculating on what Ford may or may not want from its customers. But, it’s not rocket science. They aren’t powered by magic, they are powered by electricity. Electricity has been around for over 200 years, so I’m pretty sure there are plenty of people smart enough to determine whether increasing a software time limit on full power can be handled by an insulation rating on a cable, or what needs to be upgraded, like active cooling, in order to make it safe to get longer power. Hell, I even did that for many years myself as an engineer at a company that makes electrical products.

What you say is true, except for the lithium-ion batteries. That technology is new and still evolving. They haven't even come to a consensus yet on what cathode formulations work best. Let alone are cost effective.

Just out of curiosity, has anyone verified the 5 sec issue with a GTPE build since the end of June, which included the new junction box? I’ve got one of those, have only had it for a week, but have goosed it around our local Denver freeways and no bars or 5 sec cut off so far.

Floor it past 70 mph.

The gray bars are also pretty small and easy to miss. I didn’t notice them at first either.

If you floor it from a stop, they show up around 75 mph. So it takes more than just goosing it to see them.

I would love to hear they’re gone, but would be shocked.

Mine wasn’t built with the beefier HVBJB, I have a 2021. But had it replaced with the beefier box last month, same performance and limits.

Sadly, the HVBJB isn't the only limiting factor in the GT. There are issues with the main bus bars in the battery pack being too small to handle the current draw for any period of time, as well as issues with other supporting electronics.

Exactly. And I think the main culprit is the battery pack. Pouch batteries.

It’s still there…

After 5 seconds the max current (1060 amps) is limited to 700 amps, or even less:

This is a problem even on the Model 3 Performance. After a few laps on a road course, the batteries get toasty and power gets reduced significantly.

A few laps?!?! Wow, what a dream! Wish the GT could make A lap before the batteries got toasty!

I’ve got a drill and some jumper cables and a .10 cent switch from harbor freight! Jk
Ford needs to beef up everything downstream of the motors.

Lol seriously!

We get 5 seconds, they get a few minutes…….

My wife wouldn’t be satisfied in 5 seconds, nor should she. (It happens to most men)
