Fast Charge Mercedes-Benz bclass electric (B250e)
Posted: Sat Dec 03, 2022 5:12 am
As you may see in another post, I am one of the many victims of the inevitable decline of a Tesla Large Drive Unit. In my case, as you may have surmised from this topic subject, said LDU is in a 2017 Mercedes-Benz B250e. I am fortunate enough to have had a good after-market warranty, and the car may return to me this week with a replacement motor that has been "redesigned". We'll find out soon what that means, I hope.
With that brief summary aside, I have an interest in, long before scratch building an EV, modifying this beautiful little parts box vehicle to be a little more practical for my use cases. Some mods, such as grill blocking and similar are pretty easy, and some are more interesting, like a desire to add fast charging.
To that end, I see two options: put a CHAdeMO unit in the vehicle for a slower fast charge; or take advantage of the 400 volt system as possible to CCS fast charge. My impression is that the former is simpler, and the latter is more difficult, but the potential of a 14-minute 10-80% on that tiny battery pack is a bit tempting, assuming that's even possible.
I've looked at threads on i3-based fast charging, watched a number of Damien's videos with the occasional funny cat video interuption, and am happy to hear my pipe dreams are just that or otherwise. I did, what I think is a thorough search of the forum, but forums for a new user can be a bit harder to navigate, so my sincere apologies if this isn't a novel query, or if it should somehow be lumped in with a different portion of the index.
