Installation information:
We will only sell our product to someone who is experienced and trained with high DC voltage or will have it professionally installed.
This kit will include all parts necessary for installation and very detailed instructions on how to install it, but if you are not comfortable (or don't have knowledge) working with high DC voltage DO NOT ATTEMPT TO INSTALL IT YOURSELF! We can install it for you for an additional fee, or we can recommend someone in your area to install it for you.



1) How many miles / kms of range autonomy will JdeMO™ add?

Answer: JdeMO adds about 2 miles (3 km) per minute while charging between 20% and 80% battery State Of Charge (SOC%).

 A normal 30 to 45 minute charge session will add 60 miles (96 km) up to 75 miles (120 km) of range, in about the time that you will have lunch, dinner, coffee, etc.


2) How fast will the Mercedes® B-Class ED / B250e be able to charge?

Answer: It will charge at up to 354 volts DC at a maximum of 125 amps, or about 44kW. That means that it can charge from 20% to 80% of the battery usable capacity in approximately 30-45 minutes. Most CHAdeMO® compliant chargers worldwide are between 100 amps and 125 amps "50kW".

3) What kind of chargers can I use?

Answer: You will still be able to use the existing J1772 or Type 1 or Type 2 plug for charging, and additionally you will also be able to use any CHAdeMO® charge station in the world. These are commonly known as the same quick chargers used for the Nissan LEAF®, KIA Soul EV®, Mitsubishi iMiev ®and Outlander hybrid Plug-In®. In addition, Tesla® cars can also use CHAdeMO with a Tesla® supplied adapter.

You specifically will NOT be able to use the Tesla Supercharger system, nor will it work at SAE-CCS-Combo1 or CCS-Combo2 chargers used by GM Spark EV, GM Bolt EV, Ford Focus Electric (2017 and newer), Hyundai Ioniq, Honda Clarity EV, BMW i3 and Volkswagon eGolf. (Note: BMW i3 uses CHAdeMO® in Japan).

4) Where are these CHAdeMO® chargers located?

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

5) 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.

6) 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 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.

US 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 that protects consumers, vehicle manufacturers may not refuse warranty repairs under the US Federal Clean Air Act 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.

7) Will there be a warranty on the JdeMO™? 

Answer: We include a one year limited warranty.

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

Answer: Yes.


9) 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 Rav4 EV from a CHAdeMO® charger. If you need to remove JdeMO™ for any reason, contact QC Charge for instructions.


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

Answer: No.

11) Can I install JdeMO™ myself?

Answer: Yes. WARNING: HIGH VOLTAGE CAN KILL. Follow all directions, and just know that high voltage probably won't shock you... because it will kill you, and it will hurt the entire time you are dying. But, any qualified mechanic or methodical weekend car hobbyist should have no problem with the installation, provided all the safety instructions are followed. 

12) Can my local Mercedes® B-Class ED / B250e dealer install JdeMO™?

Answer: Yes, a properly trained EV trained technician COULD install this kit. But, don't expect most Mercedes dealers to want to do this. Actually, probably exactly zero will probably want to do this.

13) How long will it take to install?

Answer: About 4 hours for us at our shop in Vista, California USA, or a weekend for a hobbyist.

14) Will JdeMO™ be able to power my house through the CHAdeMO® plug?

Answer: Maybe, however, we have not developed any method to do that.


15) I have heard that CHAdeMO® in the future will be 100kW up to 400kW capable. Will JdeMO be able to charge at that rate?

Answer: No, because in order to get the full speed would first require a 500 to 1000 volt battery. Like most modern electric vehicles, the Mercedes® B-Class ED / B250e uses a "400 volt" battery (actually 354 volts max), therefore the maximum charge rate might be up to 200 amps (about 60kW) in the future, for a short period of time, and at the lowest battery State Of Charge % (SOC%).

Currently, JdeMO™ is restricted to 125 amps / 43kW.

16) Where is JdeMO™ mounted? 

Answer: It fits entirely under the hood. To charge, you will open the hood and plug in the CHAdeMO® plug.


17) Can I move the port inlet / receptacle to another location on the car?

Answer: You can move it ANY place you like. All you need is a LOT of time, money, plus however many feet of large copper cable (2 AWG up to 00 AWG) and 18 AWG wire you need. We will not be able to provide alternate locations, sorry.
