After 5 min….”well…it’s just a cover, really.” Classic Sandy….

I am no battery expert, but the information that I was looking for in a video like this would look like this: This is a battery pack for a Mustang-Mach E AWD Standard range, 75.7 kWh nominal. It is assembled of 10 modules. 2 smaller modules of 24 cells each, 8 larger modules of 30 cells each. 48+240=288 cells. Wired in a 96s3p configuration. The smaller modules are 8s3p, the larger modules are 10s3p. In total: 2* (8s3p) + 8* (10s3p) = 96s3p. All the modules wired in series. With cells of 72 Ah nominal each: 288 * 72 Ah * 3,65 V = 75.7 kWh nominal for battery pack capacity. With your measurement of 387 V pack voltage, at the time of disassembly each cell had about 4,03 V. So, your measurement confirms 8s and 10s for the modules. 8s * 4.03 = 32.2V for the smaller modules. 10s * 4,03 V = 40.3V for the larger ones. Not shown in this video: The extended range battery pack has the same cells, but in a different configuration: The smaller modules are 28 cells, the larger modules are 32 cells. And two additional modules are stacked on top, under the rear seats. The smaller modules are 7s4p, the larger modules are 8s4p. In total: 2* (7s4p) + 10* (8s4p) = 94s4p. All the modules wired in series. (Notice the small difference in voltage due to 96s versus 94s! This diversity is unnecessary at best!) With cells of 72 Ah nominal each: 376 * 72 Ah * 3,65 V = 98.8 kWh nominal for battery pack capacity. As Ford presumably uses the same lower battery tray for both, there is some room around the sides in the standard range pack. No need to complain in so many comments. The cells themselves are pouch cells, with two pouch cells in a cell group, then getting a plastic case to give them some substance and strength. So in this standard range pack: 12 cell groups for the smaller modules, 15 cell groups for the larger ones. For the extended range pack: 14 cell groups for the smaller modules, 16 cell groups for the larger ones. The cell groups can easily be identified visually in the video and in the Jalopnik article. 2 cells in a cell group can either be 2p (most trivial) or 2s. It is a no-brainer, that cell groups of 2 cells are somewhat awkward for modules wired in a 3p configuration. Regarding use of the modules in solar applications or EV conversions from salvage packs: Ford has four module types in total for the Mustang Mach-E: From Extended Range packs: 7s4p - 28 cells, 14 cell groups, 25.5 V nominal, 7.36 kWh. 8s4p - 32 cells, 16 cell groups, 29.2 V nominal, 8.41 kWh. From Standard Range packs: 8s3p - 24 cells, 12 cell groups, 29.2 V nominal, 6.31 kWh. 10s3p - 30 cells, 15 cell groups, 36.5 V nominal, 7.88 kWh. All modules with the same height (150 mm) and width, but with different length and voltage. This can be superb, as in a EV conversion with a certain space in a particular car or boat or bike or scooter, you can choose, mix and match. Likewise, when someone wants to build a pack with a certain count of cells wired in series, like to replace some former battery pack in a certain type of EV and recreate its voltage range. With either 7s and 8s or 8s and 10s available you can mix and match to some degree. Still you cannot mix 3p and 4p modules. Or it can be unecessary as in solar energy storage systems you hvave to deal with 4 different module types (when sourcing Mach-E salvage battery packs) and their individual properties but would rather need one standard module, that is cheap and abundant. All modules are under 60V DC, which makes shipping these modules a lot easier regarding UNECE safety regulations. When you compared with Tesla battery modules: you missed the point, that you only considered the long modules from Model 3 and Model Y (22s and 26s for NCA or NMC). The smaller modules from Model S and Model X (all wired in a 6s configuration) and with equal size and nominal voltage are way easier to work with in non-Tesla applications.

Considering the terrible ground clearance on the Mach-E , It would make me a little bit concerned. Also he showed a video of a VW ID4. Pack. My recollection is it was much neater and tidier inside with less wires running all over the place. I think he made a comment how he liked that all the wiring went up the central corridor of the pack. Also I noticed on the Ford battery in the front area where those round white contactors are at. There is a small wire connector that's just hanging there unsupported at the connector. So there's a bunch of wires coming in it's a white connector that's kind of wide the other side of the connector and then wires continue and it's just hanging there. Seems to me that is a terrible risk for vibration failure. That thing's going to be jiggling around inside there until those wires fail from fatigue. Maybe there was a fastener that they already took off, but if not I would be concerned.

It's amazing that Sandy takes us on these insider tours all the time. We finally gain insight into what the auto makers are thinking when they make certain decisions and it is fantastic!

Ford can use these components on any vehicle in their lineup. The narrow modules/coolant plates can be fit into a small city car with a narrow stance. That this stuff is repairable is a secondary benefit of it being a modular, lego brick design.

Hi Sandy, I'm curious if perhaps the Mach-E top cover (the side facing the passengers inside the vehicle) was perhaps designed to be allot more fire resistant, rather than the thin sheet of aluminum in the ID4 that would like just burn up quite easily in a thermal runaway event? Watching your other brainstorming video about how best to design a battery pack, it appears to me (as a layman) that Ford might have incorporated some of those design aspects into this pack. What are your thoughts and observations on this?

For Sandy's benefit, we metric guys don't use sq cm at all ! In fact the centimetre has been a 'deprecated unit' for some 40 years. Units that are 1,000 times apart (like the metre, millimetre and kilometre) are preferred in the SI system of units. (Systeme Internationale or International System as used by all nations except the the USA, Myanmar (formerly Burma) and 1 other small country IIRC). We use sq m unless it's really tiny. That Ford battery cover looked about 3-4 sq m to me at a glance.

The cooling of the Volt cells was unusual, and was done because the power density in the plug-in hybrid application was high. In a battery-electric vehicle power density is lower and that sort of extreme cooling is unnecessary... which is why the Bolt and just about everything else uses just one module face (which is against the edges of the pouch cells) for heat transfer.

Poking your fingers in there around the orange electrical cables is a really bad idea, glad nothing happened. From what I can tell the BMS is the unit on one end with all the leads from each unit going to it. The other end has the contractors, probably DC/DC converter(s), possibly temperature measuring circuits, and various protective fuses. Looks very serviceable, and easy to swap modules in case of a bad cell compared to the latest Tesla designs. I do like the extra space inside for crash protection. One unit getting punctured should not spread fire into adjoining units. Not bad for a first effort.

Close - there's nothing in the end as large as the DC to DC converter - just contactors and fuses. The DC-to-DC is stacked on top of the charger, which in turn is mounted to the top of the structural crossmember above the front motor. jalopnik.com/a-look-at-the-engineering-behind-the-2021-ford-mustang-1839911078 The DC-to-DC is not normally placed within a battery case, in part because that would require more wiring connections through the battery case.

Looking forward to seeing the video where you disassemble the battery packs. I am very curious to see if the total amount of power is the same as the one advertised!

I don't think Munro ever tests capacity - they only quote manufacturer's specs. What they measure are weights and linear dimensions, not anything electrical, because their speciality is optimizing manufacturing costs - they don't do electrical design.

Im just starting the Video and watching the "intro". I guess Sandy is gonna LOVE all the Bolts? xD

If the battery has a thermal event it can vaporize steel. I wonder which top cover can prevent burn through the best? The composite cover at least does not conduct electricity.

Can't wait for more details.

I thought I would repost this incase you guys didn't see it. I had an idea for a video. Tesla will install 10,000 superchargers this year. What is the cost difference between the tesla superchargers and the other charging stations with their screens and RFID readers. Maybe a teardown of the chargers with an eye on how to make them more reliable and lower cost. Thanks.

The late Jack Rickard {search "EVTV"} was convinced that the best way to use a Tesla battery was to keep the whole thing together as a single high-power, high-voltage unit. He developed his own custom communication module to talk to the battery to turn it on, read back the individual cell voltages, etc all with a few CAN control cables that plugged into Tesla's connectors. Why go to all the trouble of breaking it up into its modules when you'd likely then want to reassemble multiple modules into your design of battery without {probably} the expertise to understand how to be certain that your BMS unit[s] are still doing their job. Time will tell.

Since EVs dont produce any heat, you can put plastic covers under the car to protect from salt and general dirt and such without issue. I dont know if that is what Ford has done, but Im sure all EV's will be completely plastic from the underside in the future.

i'm picking up what he's laying down. there is indeed a difference between HIGH SALT (ref Chicago) and LOW SALT. most of the treatment OEM's currently do to vehicles is only adequate for LOW SALT. Pro Tip: the key to rust prevention is simply washing the UNDERSIDE of vehicles not just the TOPSIDE vehicles (which is what our vane natures causes us to focus on). of course, properly accessing the underside of a car isn't that easy unless you have a lift or local drive thru wash with working underside cleaning option. really even a set of ramps and a garden hose will do, the idea is just to RINSE the crap off occasionally. #PREVENTATIVEMAINTANENCE

@@airheart1, but Ford though.

I agree, coolant inside the battery pack isn’t the best thing to do. It’s like fist gen Fiat 500 EV, every tube is a possible leak, and it’s more difficult to bleed. Some makers put the coolant plates outside the battery. Don’t know which is the most effective in terms of heat dissipation, but I know which is more probably to fail

It's quite fascinating to see the differing design solutions that Ford and VW have used. Faced with similar problems and objectives, they've used fairly different techniques that presumably play to their individual knowledge and experience of fabrication methods. This is good stuff ! I wouldn't say one was particularly superior to the other, merely a bit 'different' in interesting ways.

The smaller modules must be 8S3P (24 cells), and the larger modules 10S3P (30 cells), in this "standard range" Mach-E pack to add up to the 288 cells in 96S3P of that pack. jalopnik.com/a-look-at-the-engineering-behind-the-2021-ford-mustang-1839911078 This is exactly the same electrical configuration as the Chevrolet Bolt, although in the Bolt the two smaller modules physically sit on top of the rear pair of large modules, while the Mach-E puts the small pair ahead of the others. The 8S and 10S configurations lead to the 32 V and 40 V module voltages, since they strangely chose to tear down a nearly fully charged (4 volts/cell) battery. The extended range version adds two more modules over the rear pair of modules, and the modules are different to reach a 94S4P configuration of 376 cells... which implies 10 modules of 8S4P (32 cells) and two modules of 7S4P (28 cells). Both versions have the same cells; there are just more per module and more modules in the larger pack.

Great job

In the same way can we get some destructive demo of one of the sk battery( 40v cell pack) modules either over charge or over disscharge without the BMS . Also some HQ flir footage side by side of the whole thing to show how heat is moving down and out in prismatic cells .

Great video! Teslas have had cylindrical relays/contactors for a while now.

Sandy, that set of 4 contactors is for three phase power coming from the llc battery charger. The fourth contactor is a bypass for the DC fast charging direct connect to the battery. Whole assembly is known as hvjb or high voltage junction box.

No three-phase power goes to any battery; a battery is DC.

Munro = vast EXPERIENCE 💯%

4860 anode in contact with cooling plate is nice design. I get the heebie jeebies seeing all those coolant connectors and potential future leaks.

I'm not complaining about free content, but I didn't expect that "exposed" would mean just pulling the top cover off, and not measuring or removing even one module. It also seems strange to measure module voltages and not note that this means that they are 8S and 10S modules... but then, I do understand that Munro's focus is manufacturing cost, not electrical configuration. And they're "modules" Sandy; yes, technically they are "batteries", but in standard industry terminology those components are "modules".
