This may be of interest mainly to techies and nerds:

I wanted to look at the schematic for how the 12V battery in the Lightning is charged... to see, for instance, if there are any relays or MOSFETS outside the DC-DC converter and the little BMS module that hangs off the battery.

So I googled:
ford lightning schematic for 12v battery charging

Here is what Google AI came up with:
"The Ford F-150 Lightning manages its 12V battery automatically via a DC-DC converter, drawing power from the main high-voltage (HV) battery when needed, so a separate schematic isn't usually required for routine charging; instead, you monitor the battery's health, perform a BMS reset after replacement using accessory mode and pedal/headlight cycles, and use jump points (not directly the 12V battery) if jump-starting, avoiding orange HV cables."

Hmmm. If a schematic were required for charging, then I guess I would have to print it out, roll it up, and soak it in salt water to make it conductive, and use it as a cable?

"Instead, you monitor the batteries health..."
If only we could do that more easily.

Re AI slop:
Roughly 30% to 50% of software is now created by AI, with varying amounts of human oversight and intervention. If all the software in a Ford appeared rock solid, I might think that AI is having a beneficial effect on software creation.

When you think of precisely what AI doing ... It is "learning" all the intelligence AND stupidity on the internet, mixing it together so the intelligence and stupidity parts are indistinguishable, and serving it up as a co-mingled slop.

Yes, gobbledegook. A very confused response.

If you search "12v battery charging diagram ford f-150 lightning" you find a bunch of images from our posts on this forum about how to trickle charge/maintain it, etc.

Not the diagram or schematic one would hope for.

In "AI mode," there was some ambiguity about making the negative charger connection

In the Connection Points section, first it said to connect to the negative battery terminal, then it said to connect to the frame or engine block (?) so the current sensor could measure current flow.

Also, it was funny how it said "eliminating the need for an alternator."

It also said "negative terminal" in the Procedure section.

The best thing it said was "AI can make mistakes, so double-check responses."

A lot of learning to do, AI...

-----------------------AI Mode-------

An official, detailed wiring diagram for the internal 12V charging system of the Ford F-150 Lightning is typically found in technical service manuals rather than a simple public diagram. However, the system's operation and proper connection points for external charging are well-documented.


12V Battery System Operation

The Ford F-150 Lightning's 12V battery is automatically maintained by the high-voltage (HV) battery system, eliminating the need for an alternator.

  • Automatic Charging: The vehicle's internal DC-to-DC converter draws power from the large HV battery pack to charge the 12V battery when needed, such as when the state of charge (SoC) drops below a certain threshold (e.g., 30% or 40%, depending on the specific condition).
  • BMS Integration: A sophisticated Battery Management System (BMS) controls this process to ensure the 12V battery remains sufficiently charged during operation and even when parked for long periods.
External 12V Battery Charging/Jump Starting

If the 12V battery is depleted, you can charge it using a conventional automotive charger or jump-start it. The recommended practice is to use designated charging points to interact correctly with the BMS.

  • Location: The 12V battery is located in the frunk (front trunk) compartment, under a removable access panel.
  • Connection Points:
    • Recommended Method: Connect the charger/jumper cables to the dedicated jumper posts located under the passenger side frunk trim, not directly to the battery terminals themselves, to ensure the BMS is aware of the charge input.
    • Direct Connection (if necessary): If using the battery terminals directly, connect the positive cable to the positive terminal and the negative cable to the negative terminal. Connect the negative charger clamp to a ground point on the frame or engine block, away from the battery post, to allow the current sensor (part of the BMS) to measure the current flow.
Procedure for using an external charger:
  1. Ensure the F-150 Lightning is turned off and in Park (P).
  2. Locate the 12V battery or the dedicated remote jumper posts in the frunk.
  3. Attach the charger's positive cable to the positive terminal/post.
  4. Attach the charger's negative cable to the negative terminal/post or the designated ground point on the chassis.
  5. Set the charger to its slowest charge rate and power it on.
  6. Once fully charged, disconnect the charger in the reverse order (negative first, then positive).

AI can make mistakes, so double-check responses

Just think of all the resources for data centers being wasted on AI to produce such gibberish!
Terrible.
