    19 Cool facts about the technology in the Mach-e

    Construction: The rear hatch of the MME ER AWD is entirely constructed using plastic, so magnetic bumper stickers won't stick anywhere on the back. Rubber tubes along the left and right sides of the rear hatch act as pinch sensors, which stop the electric motor from closing to prevent fingers...

    HVJB Deep Dive: Is there any way that software fixes the problem of overheating contactors?

    TLDR: Probably not Longer version: Thanks to John Kelly's excellent video we can lift the mystery of the operation of the High Voltage Junction Box (HVJB) in the MME. We can also figure out the likely problem that triggered the recall for the contactor. How? Buckle up and let's get technical...

    Slow Ford Mobile EVSE: it cannot sustain the rated 32 Amps

    I notice that my Ford mobile EVSE charging cable cannot sustain the rated 32A (7.6kW) for long. After about 15 minutes the yellow light comes on periodically and it throttles back to 20A. And then it starts oscillating with a period that changes over time. Here is a plot of the power usage when...

    How much usable kWh of energy does the battery really hold?

    I have a 2022 extended range MME that I love. TLDR; If I change it full to 100%, I do not seem to get the promised 91kWh usable battery energy. It appears to be less. The GoM also shows sub-par range. So I started digging a little to find the cause. For now, it appears that the battery actually...

    A good look under the hood / frunk of my Mach-E (with parts labeled)

    I decided it was time to check out what is hidden behind the plastic of the frunk. Any maintenance - other than refilling wiper fluid - requires removing the frunk hardware. That adds to the shop cost as it takes time: Unclip the 3 plastic panels, with quite some force. Clips may fall off and...

    Co-Pilot360 and BlueCruise: ADAS doesn't perform that great in practice.

    BlueCruising on Hwy280 in Cupertino. Co-Pilot360 ADAS (Advanced Driver-Assistance System) and BlueCruise uses many sensors: Forward-looking camera in the windshield, which does the lane detection. It likely also does pedestrian detection and tracking of other obstacles in front and plays a role...

    Mustang Mach-e or an ICE car powered by dinosaur blood: which is cheaper to operate?

    In short: the cost per mile depends on the price of gasoline and the price of electricity. I make this table to help out: For example: if your electricity costs $0.15/kWh and your current gas price is $4/gallon, then the Mach-E is equivalent to a 72 MPG car. For comparison: a Prius is about...

    Peeking in the electronic brain of the Mach-e: How does energy flow?

    I used to drive a Chevy Bolt and Volt before my shiny new extended range AWD Mach-e. Chevy's electric cars displayed the propulsion and regenerative power flow conveniently on the dashboard. The Mach-e doesn't do that, so I configured car scanner pro to display and track a few nerdy parameters...
