VW Unveils New 360-kWh Mobile Charging Station

To charge where there is no power

Volkswagen presents at the turn of the year its new Mobile Charging Station, which is basically a fast charger with 360 kWh energy storage system.

Development of such stations was announced earlier this year by the way of 80th anniversary of Wolfsburg, which will get the first 12, starting in the first half of 2019. Series production and deployment in other cities is planned from 2020 by the Volkswagen Group Components (an independent business unit within the Volkswagen Group) with the goal of developing a closed life-cycle for the battery.

The 360 kWh lithium-ion battery ESS is based on the Modular Electric Toolkit (MEB), which means it will share battery modules with Volkswagen I.D. and other MEB models. That will enable it to use new batteries at a lower cost or, on the other hand, use used batteries from old EVs (second life battery project).

The Mobile Charging Station is a simple and flexible solution, which can be set up quickly and independent of the power supply wherever it is needed. The idea is to have the ability for temporary charging stations not only at large-scale events, but also other applications.

According to the German manufacturer, a fully charged station could be used 15 times, which translates to some 24 kWh on average and an average session time of 17 minutes. Then the charger needs to be replaced or recharged (if there is any connection of up to 30 kW.

Power output is up to 100 kW when one vehicle uses CCS Combo DC plug, but the power will be split between a total of four outputs – two DC and two AC.

“If the energy content of the integrated battery set is less than 20 percent, the depleted charging station is simply exchanged for a charged one. If, however, it is permanently attached to the power supply with up to 30 kW via alternating current, the battery pack perpetually recharges itself. In case the charging process is based on renewable power supply, the charging station furthermore allows the temporary storage of sustainably generated power, such as solar or wind energy – and therefore CO2-neutral mobility.”

“The mobile charging stations can be set up at defined points, for example, spread out across a city. The flexible locations can be easily found via the Internet or apps. Each charging station enables DC quick charging with up to 100 kW. In addition to electric cars, e-bikes can also be charged. Up to four vehicles can be charged simultaneously: two with DC and two with AC connections. The total battery storage capacity of up to 360 kWh is sufficient for up to 15 e-vehicles. There is also the possibility of connecting to the power supply directly, allowing the station to be charged with up to 30 kW via alternating current by means of a permanent standard grid connection. This enables charging points for electric vehicles to be set up quickly and simply, without any structural changes or major financial outlay. The battery pack in the charging station can be recharged around the clock thanks to the direct power connection. This time-independent recharging, and therefore buffering of power, also considerably reduces the strain on the power supply at peak periods.”

So this is NOT a charging robot then, right? That seems like a pretty limited application if it can only charge a small number of cats before it needs to be hauled away by ahuge diesel truck and charged off site. Might be better in a location where you only have a low power charge, like from a solar panel or something.

Also nice to see some more views of the Neo!

Well you could roll some in for specific events like ball games and rope off a section for evs where these chargers are located, they In turn could be connected to a power supply. Then when the event concludes you recharge them overnight with local power, then pick them the next morning, and take them to next location where they are needed.
Also useful for festivals, or emergency need for vehicle charging, in staging areas for disaster relief.

Even hollyday zones, where during maximun occupancy months.

It is also designed as a unit that can be placed permanently – and use renewable energy from solar and wind for example. It can also be used in ares where the infrastructure is not good enough, that can supply enough energy for these chargers. I read an article where they could be placed in older parking garages where the supply and cambling was not good enough. They could supply a fairly high amount of energy at a stable level – and then the charger could fast charge cars. The electricity could top off the battery in between fast charges, and during periods with little charging.

This can essentially be used to turn a level 2 charger into a level 3 quick charger if it’s not in use all day. For example, stick a 50A 240V connection (not much more than a US dryer/stove connection) into the back of it and it will be able to almost fully recharge each day from empty, but be able to charge vehicles at up to 100kW, rather than 12kW.

That means the user (to use their example) would be able to add 24kWh to their vehicle in 17 minutes, not have to wait for two hours or more.

A good option for both popup events (like a county show or similar) or just for remote areas where it doesn’t make sense/it’s not possible to connect a system to a high amperage connection.

Forced Volt->Bolt Conversion

“kWh” is a unit of work. Presumably we’re talking about the unit of power “kW” here.

Because if this thing is limited to delivering 360kWh, it’s sort of like a very expensive flashcube.

[pardon me– I didn’t read carefully. Yes, it’s storing work. 🙂 ]

It has a built in 350 kWh battery pack, it can be connected to mains as well, but good for temporary or rapid charging station deployment. It can charge a connected vehicle up to 100 kW and supports charging up to 4 vehicles (2 AC and 2 DC).

A 360kWh battery powered DC quick charger that charges continuously on a 220v circuit would provide the ability to quickcharge 5 to 15 cars a day without a special power supply or connection. It just needs the same kind of charger that EV’s have onboard. It’s a good idea for remote locations that are never in continuous use assuming the batteries cost less than an actual quickcharger installation.

12 first (inverted: first 12)

I liked this by EV West: ’57 Porche’ (replica) Speedster with Model S battery conversion:

considering all they have are computer renders here, I’m guessing these don’t actually exist yet. I am curious what such a station would cost. On the bright side, it would be handy for installing in locations where it is difficult to get the sort of high power connection to the grid that a regular DC fast charger would need.

They have at least a few working models. They have already been in test use. Volume production is not begun for sure. I don’t even know it that location has been determined yet.

Take it to the track, and soon you could sell those KWh like ice cream.

My question is when is the Crozz coming to the US?


These are mistakes. Way too big, esp since the truck’s megachargers are coming.
What is needed is for the west to start pushing for increased energy, while avoiding coal, but ideally, ALL fossil fuel.
China is gearing up by ADDING (not replacing) more coal plants than America has and that is just in China.
It does not include the fact that China is building more coal plants in other nations. All up and running by end of 2020.

What does this have to do with megachargers and coal?

Do Not Read Between The Lines

More coal plants != more coal electricity.
Capacity factors for coal plants in China have been falling.

360 kwh. Ability to charge 5 cars. This might make sense if connected to a 480 and the battery is used to smooth demand out, but otherwise, this is so minor of an amount as to not matter.

Maybe they decided to make the thing rechargeable so that they could use it again.

Is this for real? Or an imaginary charging station for VW imaginary EV cars.

Do Not Read Between The Lines

It’s a concept charging station.

Just kidding.

They have some prototypes. Principle is reasonable. Travel demand has some extreme peaks, and EV charging is slow enough to cause logistical issues. Tesla owners have found that with eclipse, SpaceX launch and some holiday travel.
