JdeMO for Mercedes B-Class ED

I would like to begin an interest list for folks with the Mercedes B-Class ED to add a DC quick charging to the Mercedes B-Class ED called "JdeMO".


1) How fast will JdeMO be able to charge?

Answer: It will charge at approximately 350 volts DC at up to 125 amps, or about 42kW. That means that it can charge from 20% to 80% of the battery usable capacity in approximately 30 minutes.

2) What kind of chargers can I use?

Answer: You will still be able to use the existing J1772 plug for charging, and additionally will also be able to also use any CHAdeMO charge station anywhere in the world. You will not be able to use both at the same time.

CHAdeMO is commonly known as the same quick charger used for the Nissan LEAF, KIA Soul EV or Mitsubishi iMiev.

You specifically will NOT be able to use the Tesla Supercharger system, nor will it work at SAE CCS Combo1 chargers used by GM Spark EV, Bolt EV, BMW i3 and Volkswagon eGolf.

There are 14,000 CHAdeMO stations around the world:

2000 - US / Canada
4000 - Europe
8000 - Japan


3) Where are these CHAdeMO chargers located?

Answer: We recommend using http://www.PlugShare.com or http://www.chademo.com to find a station.


4) Will JdeMO damage the car in any way?

Answer: No, If operating as designed. But, increasing the charge rate to any battery that has ever been designed in the history of mankind will likely shorten its lifespan.

5) Will it void my warranty?

Answer: It should not void any warranty, however we do not have control of how any auto manufacturer will likely handle a battery warranty claim. In all likelihood, any battery failure would likely be blamed on any product connected to the battery, no matter how unlikely it actually did damage. Therefore, each JdeMO sale will require a "hold harmless" agreement that indemnifies Quick Charge Power LLC from any claim.

Federal law sets forth requirements for warranties and contains a number of provisions to prevent vehicle manufacturers, dealers and others from unjustly denying warranty coverage. With regard to aftermarket parts, the spirit of the law is that warranty coverage cannot be denied simply because such parts are present on the vehicle, or have been used. The warranty coverage can be denied only if the aftermarket part caused the malfunction or damage for which warranty coverage is sought. Disputes in this area usually boil down to arguments over facts and technical opinions, rather than arguments over interpretations of the law.
Like the Magnuson-Moss Act, vehicle manufacturers may not refuse warranty repairs under the Clean Air Acts performance and defect warranties merely because aftermarket parts have been installed on the vehicle. The only circumstance under which the vehicle manufacturer can void the emissions warranties is if an aftermarket part is responsible for (causes) the warranty claim.

Should something go wrong, the warranty provider will need to determine the cause of the problem. The Federal Trade Commission says, “The manufacturer or dealer must show that the aftermarket or recycled part caused the need for repairs before denying warranty coverage.” That means if the dealer can prove (the burden is on the dealer) the problem was caused by the wrong viscosity or a poor quality oil filter, your warranty can be denied. Warranty protection would still be in effect for other parts of the cars.

6) Will there be a warranty on the JdeMO?

Answer: All Quick Charge Power products offer a one year limited warranty.

7) Will it be possible to remove JdeMO on a lease return car?

Answer: Yes

8) Do I need to remove JdeMO to have normal service or maintenance performed?

Answer: Absolutely not. We specifically do not want you handling, modifying, repairing or in any way changing JdeMO except to recharge your car from a CHAdeMO charger. If you need to remove JdeMO for any reason, contact Quick Charge Power for instructions.


9) Can I charge with a CHAdeMO charger and the J1772 plug at the same time?

Answer: No

10) Can I install JdeMO myself?

Answer: Yes, however:


11) Can my local Mercedes dealer install JdeMO?

Answer: Yes, with a properly EV trained technician. The chances of that actually happening at a dealer is slim. Perhaps a local mechanic would "moonlight" for you?

12) How long will it take to install?

Answer: About 2-3 hours.

13) Will JdeMO be able to power my house through the CHAdeMO plug?

Answer: Yes, it will be compatible with CHAdeMO specifications, therefore with appropriate external equipment, it may work. There are currently a lot of unknowns in this area.

14) I have heard that CHAdeMO in the future will be 400kW capable. Will JdeMO be able to charge at that rate?

Answer: No, because in order to get the full 400kW would require a 1000 volt battery at 400 amps. Like most modern electric vehicles, the Mercedes B-Class ED uses a 350 volt battery, therefore the maximum charge rate would likely be about 200 amps multiplied by 320 volts, or about 64kW.

15) Where will JdeMO be mounted?

Answer: It will all fit entirely under the hood. To charge, you will open the hood and plug in the CHAdeMO plug. We will offer a hood strut kit, just as we do for the Rav4 EV

16) How much will it cost?

Answer: We believe the cost will be $2999

17) I heard that there may be an SAE - CCS Combo1 option from Mercedes in the future.

Answer: Mercedes is a signatory member to that standard, and they may provide that in the future. Currently, they do not

18) Will you offer an SAE-CCS Combo1 adaptor in the future.

Answer: Absolutely not, for the reasons stated above.

To get on the JdeMO interest list, just send an email to:

We started "monkeying around" with JdeMO for the B-Class ED today. I think it's going to be pretty straight forward.

Hi Tony,

I am considering buying a B-class in Portugal and I wonder if you where able to retrofit the fast charging solution into a B-Class, and if so is there a step by step tutorial for me to install one once I purchase my b-class?

best regards

As far as I know he has a number of installer in the US. I think Tony will install in Europe but you have install costs plus airfare.

Dangerous voltages are involved and it is not a DIY project for most people.

I am back to another 2017 Cirrus White B250E
It is around $75 more and I like it!

I installed Jdemo on my RAV4 EV with a friend (a HV trained Toyota mechanic). You just need a workshop with "High Voltage" expirience. With Tonys installation manual we fixed it in 1 1/2 hours.
