Mercedes-Benz B-Class Electric Drive Under The Skin – Photos

Daimler recently released a new set of illustrations of Mercedes-Benz B-Class Electric Drive, including several of the drivetrain.

As we can see, most parts are installed above the front axle where there’s a Tesla-style (and Tesla manufactured) electric motor (132 kW), transmission and inverter. Like in some other EVs, on top of the stack is the on-board charger.

Everything seems to be liquid cooled (see the thicket of blue pipes).

The 36 kWh lithium-ion battery pack (28 kWh available as standard plus option to use more) is placed in the sandwich floor.

Editor’s Note:  The full battery is available in the 2015 refreshed edition of the B-Class ED, as the extended range option is deleted.

On the last photo there is the European version of the charging inlet – the 3-phase type 2.

Are the batteries Tesla-style as well? Or are they large-format cells like every other manufacturer?

DaveMart

Tesla.

Mercedes use different non-Tesla stuff for their PHEVs

electric-car-insider.com

Where”s the quick charge port?

DaveMart

‘Even though Mercedes used Tesla’s system, access to the Tesla Supercharger network is not available. Furthermore, this generation of B-Class Electric offers no quick charge port (for using CHAdeMO or SAE Combo public quick charging). Mercedes engineers told PluginCars.com that they preferred to use the existing fuel door on the back left side of the vehicle, rather than changing the car’s sheet metal to accommodate a bigger port for faster charging. Quick charging is being considered for future model years.
Mercedes also considered—but ultimately rejected—the use of a small range-extending gasoline engine, in a desire to keep the EV system simple and compact.’

They also intend:
‘Messy charging cables could soon be a thing of the past thanks to a groundbreaking wireless charging system that Mercedes is aiming to offer within the next two years. We were given a demonstration of the technology using the new Mercedes S500 Plug-in hybrid – likely to be the first model offered with the tech.’

Whether that is B-Class BEV bound I don’t know.

I thought the whole point of CCS was that existing size fuel filler doors could be used.

No matter how good the wireless charging is, the vehicle will have to have conductive charging as a backup for locations that do not have inductive charging installed.

Also, what’s in all that space ahead of the battery? If the pictured battery is 36kWh total, then at least 50kWh total would fit in the remaining under-floor space. Put that much battery and a fast charge port and I would buy one.

+1. I thought the SSC combo was adopted by some companies to slow down Nissans EV efforts J/K. the idea was to have only 1 plug/socket to save a few dollars on the fabrication costs of the car.

Sorry DaveMart, I should have put the /s tag on that. Really helpful reply tho, thanks!

DaveMart

Thanks for the thanks!
I have no idea what an /s tag is though!

Beth

a company called quick charge power is expected to have a quick charge adaptor for this car sometime in 2015

QCO

That “thicket of pipes” looks like a coolant leak waiting to happen.

Surely they can do better than that when engineering the cooling system.

DaveMart

Surely you are not questioning the righteousness of Tesla engineering?

The faithful will descend to smite the unbeliever!

Nick

They couldn’t help but go overboard with the plumbing.

That’s half the expertise of a company which makes ICE power plants. 🙂

George Bower

I haven’t been following that vehicle. But it looks like a nice offering.

Good details in the article on the power train.

Anon

The MB grill looks simply *RETARDED* on an EV. Just badge over a nosecone with your fancy chrome logo, and call it a day…

Oh, and why not use your HUGE GRILL LOGO as a CSS Chargeport Door, while you’re at it???

Miggy

Agree that the charge port should be on the front of the car, 132kw motor is a good size.
wish MB would make the A-Class in a EV as it is a far better looking car.

revolutionX

Still needs a Searl Generator in it. 😉

QuickCharge Power will offer a ChaDeMo DCQC option for the B Class next year, following the release of their JDeMo DCQC product for the RAV4EV.

Bill Howland

So if the North American version has a Tesla-Esque 9.6 kw single-phase charger thingy, does the ROW (rest of world) Mennekes version have the standard 11 kw 380 volt thingy?
