>then I needed to find a brake controller that can work with the higher voltage (14.4v vs the normal 12v)

Put a voltmeter on the battery terminals of a regular car at 2000rpm and note the voltage. You'd be surpised (the alternator can produce as high as 15V on some cars).

The vacuum reservoir of the brake booster in cars with vacuum servo brakes (whether vacuum is generated by the engine or an electric pump is irrelevant) stores enough energy for 3-4 full applications of the brakes.

Hooks, holes in the backing plate, stamped/cast dimples, welded wire-mesh for the backing material to adhere to.

Pads were the friction material is solely using glue to adhere to the backing plate are generally either very cheap aftermarket replacements or the OEM cheapening out.

Unsteady 30FPS with terrible frame pacing is nothing that consoles can brag about.

Nothing "directly" runs on 12V either. All electronics will have stepdown converters in both the 12V and 48V use case. Motors, solenoids and incandescent bulbs can be made to work with either voltage (the same way we do for 24V systems in heavy goods vehicles here in Europe).

>Maybe the car has an AC compressor or a pump to cool the battery during charging, which draws directly from the charger when plugged in

No it doesn't. A/C compressors in EVs are 3 phase AC powered by an inverter supplied by the traction battery.

The contactors in an EVSE open and close at practically zero current, the OBC ramps the current up or down accordingly. And as another sibling comment noted, the OBCs are PFC corrected and act as a largely resistive load.
