E/W214: Charging E53
A separate issue is that I'd rather not charge the EV using the generator unless I give it a one-time permission. I'd rather save the generator fuel for the house. It is also more efficient for the utility to generate electricity. On the PHEV, I can wait to charge the car until the grid is up. I could see a potential with the grid out that I would want to charge the EV using the generator to get some range on the car when the gas pumps are down due to the electrical outage.
I'd like to have a device that senses that the house is powered from the grid and turns off the EV charger circuit unless I override it. It is an edge case, but I would be interested in such a product.
The posted PDFs are helpful. Should we have received some sort of PHEV manual with the car? I went through all of the paperwork and there was:
1. Standard E-Class owners manual. I didn't see any PHEV/charging information.
2. Quick Overview Guide
3. Maintenance manual/logbook
4. Very limited manual with the included Webasto charging cable pack (sort of a short pictorial of the two plugs and then legalese).
I think we have everything figured out but I do want to make sure we have a complete set of manuals...for the next guy.
- Open the outside charging door by pressing on the center, similar to how you open the door for filling a Mercedes with gasoline.
- Push a button by the charger port to open the charger socket cover.
- Insert the charger connector until in clicks in place. Make sure the cable is not in tension.
The second question I had was "how do I stop charging?" You can see the process for stopping charging to the car here: Ending the AC charging process (level 1/2) | E-Class Wagon July 2025 S214 MBUX | Owner's Manual. Here's a summary of how to stop charging.
- If the car reaches its target state of charge, it will stop charging.
- If you press the "Cancel charging button near the charging socket, it will stop charging
- If you use the "stop charging" button in the EV charger app, it will stop charging.
- Once charging is stopped, press and hold the button on the charger connector to remove it from the charging socket.
- Close the socket cover and flap
- The locking status lamp on the left will be white if the charging cable is locked to the vehicle. The upper curve socket light will light up the socket and match with the locking status lamp.
- The charging progress lamp, which is matched by the lower arc over the socket:
- will be green if the charging process is complete
- flashes green if charging is in process
- orange if there is a charging break (charging started but didn't complete but hasn't reached target SoC0
- flashes orange if the connection is being established
- flashes red if charging is not possible due to malfunction
Here are some setting options:
- You can setup three separate charging programs. You can save your home GPS position and associate it to one of the charging programs.
- If you are charging on level three fast charger, you can choose to charge at up to 20 kW (the default) or do a one-time override to charge at 60 kW.
- You can set the departure time. This will coordinate with the vehicle's pre-entry clime controls to heat or cool the cabin by the time of departure. The charging time will be optimized for the departure time.
- You can enter charging breaks, if for example, you don't want to charge at utility peak times.
- You can change the charging power.
- You can set the maximum charge level
At first glance it may appear that there are a number of options. In practice, you plug the charging connector into the socket to charge. Then you end charging (via the car button, app, full charge, etc.) Then you remove the charging cable and holster it in the charger. It is quicker than using a gas pump in everyday usage.




Charger gets good reviews - especially for very cold weather conditions we get in southern Ontario. The long 24 ft. cable is thin and not subject to stiffness when cold
and will reach both cars in the driveway.
That said, I'm looking for feedback from anyone who has made the same choice and how the Tesla Universal charger works with the M-B PHEV's. If you made a different
choice - and charge in a cold weather climate - I'm interested in your reasoning.
Thanks,

are known to go stiff during really cold weather - unlike the thinner Tesla cables. Just wondering if anyone has used the Tesla universal during really cold weather.




Chicago weather with charging overnight at below zero Fahrenheit temperatures with no effect on charge times, cable flexibility, etc. Compatible with MB and Subaru EV - and future proof as Tesla compatible cable is a $99 swap.

If you want really pliable cables in the winter, a rubberized cable that gets high ratings on State of Charge will be the best. However, by the looks of the Tesla cable on the video, it performed very well, due to the thinness of the cable. I would be happy with the Tesla Univeral Wall charger in the winter in my location in in the North East US. In Canada, cold weather cable pliability may be more of a consideration.
I have the Autel MaxiCharger. The reviewer on State of Charge says the Autel is a great charger but the cold weather performance of the cable is really bad. My Autel cable is noticeably stiffer at 9 degrees F, but it doesn't bother me because my cable run to the car is about 4 feet, so I'm not coiling cable on a daily basis. If I was using a longer cable run, a cable that was easier to coil in the winter would be a strong selling point.
- Why is the default charging program 'standard'? I would think the vast majority of cars are being charged at home the vast majority of the time.
- Why doesn't the charging program automatically default to 'home' when parked at home? Yes, it briefly offers a screen prompt, but generally I am occupied by other things pulling into the driveway.
- Why can't the charging pauses be programmed by day? Certainly this metropolis of 17m is not the only place where time-of-use metering is different on weekdays and weekends.
- Why are the charging pauses not linked to charging programs? Obviously a 'home' program will have different pauses than a 'standard' or 'work' program.

I think the charging program is reverting to standard after the charging completes. I was assuming the selected charging program would remain in place until a different charging program was selected.
When I tried to enter charging pauses to exclude peak times, it saved the pause as 12:00am-12:00am which means that it is always paused. I got into the car the next day to find that it hadn't charged at all.
My workarounds are:
1) Change the standard program to be my home program settings. If I want to program an alternate SOC target, I change the home program and select the home program
2) I press the charge options button on the center console before charging for the day to review the charging plan for the night.
2) Use my utility to charge only off-peak so I don't need to program charging pauses. (This option is probably not available to most people.)
Mercedes may have botched the turn signal indicators by hiding them behind the steering wheel, but the interface to what's happening with the electric motor, traction battery and combustion engine is a great design.
Since the driving experience is so good, I can forgive the issues that @Alan Smithee mentioned. I'm betting that Mercedes will fix those issues in future software releases because they are obvious to anyone who charges the car.
Then his drunk cousin who plays Angry Birds 6 hours a day at work placed the turn signal indicators on the display and wrote the charging program program.
