Pugeot E-208, Corsa E, etc. battery pack.

Post by SciroccoEV »

Just took delivery on one of these 50kWh packs yesterday. Had to have it dropped at the kerb and then strip in place.

BMW use a lot of bolts and their packs are easy to dismantle. These packs use only a few bolts, but a lot of strong adhesive and most of the battle was getting the sheet metal cover off, which took several hours.

Quite a complex layout due to the ICE derived nature of the donor.

The 350kg weight shown on the casing is probably the 'lifting wieght', which is the minimum required capacity of shackles, straps and cranes, etc. rather than the actual weight.

I'll try and get real weights on most parts. The stripped steel casing is just a shade over 75kg.

nice find, funny layout indeed.
Moved the thread into the PSA section. Is that actually morphed into Stellantis nowadays?

Yes, part of Stellantis, which sounds like a 70's Supergroup.

Calb modules, 6S2P, Calb BMS. Mostly solid copper busbars, but some have short sections of round flexible cable. Terminal caps are a nice design that keeps the M6 Torx screw captive.

Cooling plates are interesting. The big 6 module plate is very light, made of embossed sheet metal. The two on the left of the picture, a 4 module and a 6, double up as tructural mounts and are pretty heavy.

I thought I would put together a list of things I have found out about the Peugeot e-208 CATL modules.

Firstly a big thank you to Clanarn for designing the master board, bexander for the software and chris01290 for software and general advice.

The e-208 modules use the MAX178xx family of devices. e208 modules using Max17823B and the master to control these is MAX17841B as the master controller.

Clanarn has made a niffy little board using the MAX17841B, please bear in mind that this board only uses the 4 middle pins on the TX/RX end.

ie
TXN pin 1 Not Used
TXN pin 2 Not Used
TXP pin 3 is TXN and goes to pin 1 on Module 1 (RXNL)
TXP pin 4 is TXP and goes to pin 7 on Module 1 (RXPL)
RXN pin 5 is RXN and goes to pin 8 on Module 1 (TXNL)
RXN pin 6 is RXP and goes to pin 3 on module 1 (TXPL)
RXP pin 7 Not Used
RXP pin 8 Not Used

Wiring on the Modules, look at the rear of the connector plugged in the module the right way up. Pin 1 Top Left, Pin 6 Top Right, Pin 7 Bottom Left, Pin 12 Bottom Right

Pin 1 RXNL
Pin 2 blank
Pin 3 TXPL
Pin 4 blank
Pin 5 goes to pin 8 on Module 2
Pin 6 goes to pin 7 on Module 2
Pin 7 RXPL
Pin 8 TXNL
Pin 9 blank
Pin 10 goes to pin 3 on Module 2
Pin 11 blank
Pin 12 goes to pin 1 on Module 2

and so on until the end when Pin 5 loops back to Pin 12 and Pin 6 to Pin 10, the end of the daisy chain.

I believe the original wiring harness twists the wrong pairs!

The Cells are connected to the first six Channels, so voltages are read from the address 0x20 to 0x25.

Now onto the cell temperature sensors. each module has three NTC and are not contacted as the MAX chip manufacturer recommends.

Being three the board uses a combination of two logic gates, which use GPIO 0 and GPIO 1 to switch outputs/inputs

Address 0x11 drives the GPIO,
so 0x7001 selects NTC1 and NTC2 with NTC1 connected to AUXIN1 and NTC2 connected to AUXIN2
and 0x7002 select NTC3 connected to AUXIN2, AUXIN1 is left unconnected and should not be stored.

I have also found that the THRM voltage needs to be switched on to let the circuit settle. I leave it on by using address 0x19 0x0310, the 3 is the THRM on and the 10 is a small delay, may not need it.

The address 0x2D is for NTC1 and leads with the LSB then MSB. Shift the LSB 4 to the right and MSB 4 to the left and add the two together
measTemperature = ((readRegisterData[3 + (i * 2)] << 4) + (readRegisterData[2 + (i * 2)]>>4));
i being the module number.
Address 0x2E for NTC2 and 3
The good news is the read-out is linear.

So for NTC1
temperature = (measTemperature - 1680)/32;
and for NTC2 and NTC 3
temperature = (2450 - measTemperature)/31;

Both in C

I was not allowed to take over control of the freezer for a couple of days, I was told that was a step too far. So freezer packs and hair dryier were used, and the readings were linear I just may be a deg or two out.

By the way, NTC1 is in the middle, NTC 2 and NTC 3 are next to the module terminals.

I have not added the documents for the MAX178xx family as these are already been added to this post along with examples of software.

Hope this helps.

Out of curiosity do we have any weights and sizes of the modules that I could add to the wiki as they do look ev friendly 😁

I am assuming that they are different from the calb modules that zero ev cell otherwise these would be 132s in total 🤪

Details of the modules

Voltage: 21.9v
Capacity: 2.73kWh
Weight: 12kg
Width: 150mm
Length: 390mm
Height: 115mm

Checked the dimensions, not the weight, but 12kg feels about right.

12.7kg would be more like it.

Hi Guys,

I am about to take delivery of one of these packs next week.

Does anyone have the latest and greatest code that works with them and has it been intergrated to SIMP BMS at all?

I have seen a few posts spread over the forum with various snippets of code, but could not find the original source.

its not built into simp,
the following thread has the current state of play on interpreting the bms (i haven't read it)
viewtopic.php?t=2181&start=25

added info to wiki,
those modules do look damn good, extremely good on weight and volume... I want some ... goto finish current build first before thinking of upgrades :)

Guys does this thread state that Pugeot E-208 and Corsa E are both 6S2P? and are the same?
Or is it more like commonality wise?

Maybe someone is interested to see how much current can deliver this battery.
I have a video here in which I continuously discharge the battery with more than 540A for about 1.5 min.
The voltage sagging is about 9, 10% at this discharge rate.
Enjoy!

Hi

I would like to ask you if that metal cooling plate is a one part? Or this is five connected metal plates?
I bought E Mokka and it has a same battery, I bought it with damaged battery, and that metal part which cooling pipes goes in to are broken. Also probably the metal cooling plate is broken too. Maybe you have it for sale?

hi

The part you circled is one big part. I have a empty shell with the cooling plates that i am not using.

Hi, thank you for your reply. I live near Manchester, but happy to travel to pick it up. As my battery pack was impacted from the bottom and probably that metal plate is damaged as there is a leak of the coolant.

Is there any chance that I can buy it from you?

Hi all, I'm considering buying the 50kwh Open Mokka battery pack. But I can't find opinion data on degradation, reusing OEM parts like BMS etc... Some one here can provide some light? Thanks

Hi you can use the modules and if needed the cooling plates.
With third party BMS, like mine, you get full control over the parameters and or configuration.

Re-use of HV relais might be possible too. Depending on the type used in this vehicle.

Dear tread members,
Still looking for UN38.3 or any other cell level info on the pack.

Would buy this information if available!
