I don't have a written source I can refer you to. I did have a long discussion with someone (an electrical engineer I work with and trust) who had personally looked at the voltages and signaling during a session on one of these and described it basically as I did above. I don't think there are...

It really is a bug that it works. What they're doing is starting a DC charging session then, at the "charger" end, violating the CCS spec by dropping the voltage instead of raising it, so current flows from the vehicle instead of to the vehicle. There is a standard for bidirectional DC...

It's a fundamental design problem. There are wires connecting every component in this system but there are multiple wireless hops used instead. To produce software fixes with the outcome of a reliable product would mean enhancing the firmware of multiple modules in the truck, and the Siemens...

Just to close out one more open question - I have been told by a Ford engineer, though not one who works in this particular area, that Ford rates its wheels lower on the front than the rear because the front wheels take more lateral forces in cornering and in off-road/"urban" driving (curb...

It's not as bad as you think - the total for the 4 wheels needs to add up to the vehicle's GVWR in order to maintain your payload rating. The Lightning wheels are rated for 2,475 rear, 2,025 front - conveniently, exactly 9,000lb. The burliest ICE wheel (the "64H" HDPP wheel) is rated for 2,275...

Our trucks, particularly those with the ER battery, are so heavy that they usually have _lower_ payload ratings than comparable ICE F150 models. I can overload my ER Lariat easily by filling the box with firewood, and I do move firewood in the winter. Everyone uses their vehicle in their own...

Most factory F150 wheels are not rated for the weight of the Lightning (at least not the ER, it's a little easier with the SR trucks). Only the actual Lightning wheels and the "64H" wheel supplied on some Heavy Duty Payload Package trucks are. More info here.

That address at ARL is one of the original root DNS servers. It's been renamed to "do-not-reuse" to remind ARL staff that it's now unusable for any other purpose because ancient software like the version of QNX in our trucks bombards it with literally billions of DNS queries per minute even...

We had a Prius that did this with the glovebox light despite multiple replacements of the switch and attempts to trace out the wiring for any problems. The result was basically that every morning we started out with a low state of charge in the hybrid battery no matter what state we brought it...

The simple answer is "not reliably". The truck uses GPS for this and there just isn't enough precision. In some cases like with chargers around opposite corners of the building (I have this one place I frequently charge) it will *intermittently* decide they're different locations and so you'll...

This can be adjusted with Forscan. The calculated values from the common formula for rolling circumference seem to result in a displayed speed that is off by about 1MPH at 60MPH and by trial and error I have concluded that a roughly 60mm correction to the stored value fixes this even though the...

We punctured two radiators on our first Tesla within a year of ownership (looked to be from gravel strikes) and broke the power steering box on a rock. They are certainly not invulnerably armored.

The entire system design is fatally flawed. It uses multiple wireless technologies along the path from truck to inverter when there are perfectly good wires, supporting arbitrary communication (CCS uses ethernet-over-powerline for signaling!). It's not going to get fixed.

They kind of have to because they need to be at the same voltage or a calculated, precise offset. The easiest way to do this is to have one control the other.

Because the J1772 standard maxes out at 80A (100% pilot duty cycle). There is no standard way for a charger and EVSE to indicate that either side is capable of handling more current. There are a lot of other practical reasons for this limit. 96A charging would require a 125A breaker at the...

The above is false. Only the AC pins are used for 80 amp AC charging. The DC pins on the Ford Charge Station Pro are for use with the Home Integration System only. A dual-charger Lightning will charge at 80A with any 80A J1772 EVSE, such as the Wattzilla or Grizzl-E or the Gen2 Tesla HPWC...

CF6 has something of a history of uncontained engine failures.

@Ford Motor Company sure looks like another problem dealer damaging the brand...

I know, and we're lucky to have you here. Please don't mistake my frustration with the results that Ford the gigantic corporation as a whole is able to deliver for dissatisfaction with or ingratitude for your efforts. At least with you here there's some channel for owners' feedback to reach...

One of the better lessons Ford could take from this and similar events is that Jesse is an asset to the brand, not some kind of enemy. He's basically a super specialized independent mechanic who can solve problems most dealerships can't. Ford should find a way to collaborate with him or at...
