So a thaught...

The battery can be range charged using the button on the dash on some models. How does the chademo interact with that option? And what happens on models without that option?
Yes, you get a freebie. Range / extended charging that would ordinarily cost beaucoup Dollars / Pounds / Euros from Mercedes is included with JdeMO.

You don’t even have to hit the silly little button to make it work. JdeMO just keeps charging to 100%.

Hello @TonyWilliams
Thanks for your work and all the informations provided on JdeMO charger.
Could you please confirm the temperature of the cells by using the DC charger at the end of the charge session...

I know that the B class use liquid thermal management but I would like to be sure that the temperature of the cells will be below the maximum of the specification (it’s important for NCA cell).
Thanks
I didn’t look at the Kia stuff, because it just doesn’t apply. The Tesla designed cooling system in the Mercedes works just fine.

When you are charging at 125 amps, expect the battery to warm by 2-7C (assuming the battery is at room temperature when you start).

We have to include controls to protect the battery. It could have been sitting in the desert in the summer for all we know, or frozen in a snow drift. Once you have the car on, the temperature management will work hard to get the cells between 10C and about 40C.

The installation of JdeMO for the Mercedes B-Class ED is easy.

1) Disable the High Voltage power

2) Disconnect and remove the 12 volt battery

3) Remove these hardware parts that were under the 12 volt battery

7) Lift the vehicle to work underneath

8) Remove underbody plastic panels

9) Unplug the High Voltage connector from the Tesla battery

10) Connect the 2 High Voltage cables from the JdeMO assembly to the JdeMO Junction Box

11) Plug the JdeMO Junction Box into the Tesla battery

12) Mount the JdeMO Junction Box with 4 bolts

13) Plug in the Mercedes High Voltage plug (that was previously in the Tesla Battery) into the JdeMO Junction Box

14) Reinstall all underbody plastic panels

15) Reconect High Voltage safety disconnect

16) Reconnect 12 volt battery

17) Turn on the car

18) Test JdeMO at a functioning CHAdeMO charge station

The kit will be available in California first.

Then throughout the USA.

Then Europe.
Hi Tony, Really enthusiastic about the prospect of fast charging for the MB B250e. Would really boost the life of these models even though this is clearly going to be restricted to second hand models now.

Any update would be appreciated if you have an expected timeline for a fast charging bolt-on for that would work for the UK? Assuming the availability is now here in UK just need someone that is able to fit it.

Thanks and thumbs up.

Hi Tony,
Thanks you for the informations and your job.
One last question, your low voltage harness communicate on the CAN bus with the BMS of the vehicle to share the data (Battery voltage, battery current, etc... ) or you have another BMS integrated on your module and you don't use the information from the CAN bus ?

We use the existing Tesla BMS data to formulate our charging protocol. The data is on the Tesla CAN bus.

Hi @TonyWilliams ,

I have paid the deposit when will you require the final payment and like above what is the likely delivery date.

Thanks

Rich
Rich, when the units are built, tested, and ready to ship (hopefully Dec 2018), we will ask for the remaining $1499, plus shipping, taxes, etc.

(2600mah * 3.7v nominal) (84S * 44P) =
(9.620Wh) (3696 cells) =
35.5kWh rated capacity

Published usable capacity:

28.0kWh
31.5kWh

There isn’t 10% loss in a proper DC to DC transfer. Maybe 1-2%
