Siemens is readying the launch of its 22 kW Charge CP700A plug-in vehicle charger in Europe. The German firm claims that the CP700A can charge up a typical electric car's battery pack to full capacity in less than 60 minutes.
The CP700A can charge battery-powered vehicles at different rates. For example, electric two-wheelers, which are typically charged through a household plug, can be hooked to and charged by the CP700A at a reduced 3.7 kW. This is made possible by the CP700A's ability to communicate with the vehicle and determine whether or not it can support charging at the maximum (22 kW) current or only at a reduced level.

Siemens electrical mobility team head Ralph Griewing says that the CP700A makes charging as simple as fueling up a vehicle with gasoline. With simplicity and safety in mind, Siemens equipped the CP700A with a display screen that guides users through the charging process and a power socket that doesn't have voltage until the command to commence charging is given. Prototypes of the CP700A have been in use in Germany and the 22 kW chargers will soon swing into action to charge up the EU-sponsored Green eMotion project.

      Read this very interesting Wiki on European standards evolution :

      @nottoosmart. Thanks a lot for your very usefull links. Found almost everything in them.

      The 22KW is done with Tri-Phased AC current 480V. Very good in my view in terms of future proof. Limited to 32A on single phase 220V AC means 7KW then, normal. No DC.

      The 500Miles battery of my dreams (Same range as a full gasoline tank) would require # 130KWH capacity, means with a 22KW charger it could fully recharge in #6H. Not instant, nor

        In fact the single phase is even limited to 16A means 3.7KW on this charger. So it's really only for triple-phase AC charging at up to 22KW. But this is fine for me. Future proof enough at this stage with Mode 2 & 3 handled over solid German Minnekes plug. Only real missing may be DC but to be franck, but this is not mandatory for my home carpark. If AC Tri-Phases 22KW can charge my future dream 500Miles / 130KWH battery overnight, I can stay with that charger at my home car park for a very long time (130KWH battery is at best a 5 years dream. 1st step being 50KWMH within 2 years, at best).
        We'll just need the DC for fast charging "on the road", not at home, starting 2014 in EU.
        In understood on the Wiki link that DC CHAdeMO like charging Mode 4 was considered on top of German Minnekes Plug 2 in rev 3 of the EU spec to be finalised by end of 2012, and published in 2013. Means 2014 to find that on the road...
        So I'm now ready to buy 1st EV with 50KWH battery + Extended Range....
        Should I dream a Volt2 SUV in 2012 ? Or a BMW X4/X6 Phug In Hybrid with Ext Range ?

      A few more carasteristics would have been more than welcome here, plus a picture of the std plug(s) offered too.

      Important here is to understand if this is a monophased 220V AC only charger (Means 22KW = 100A x 220V) or a tri-phases 460V AC charger (Less Amps needed), and if it can also do DC current for very fast charges (Japan way). Neither are very standard settings in homes and collective garage/parking installations, since most 220V mono-phase lines are limited to 32A (7KW) and tri-phases lines are less limited but also a lot less frequent in such places, and native DC exist almost nowhere today at required current for this.

      Does not say either what intelligence its has built-in and if they are cooperating with partner Electricity Companies also involved in Green eMotion project (EDF, ENEL, ...etc), beyond recognizing the recharge power supported by target battery system....which is very "short" vs EV users expectations. Key for me here, would be that it can recognize "your car", and bill "you" on your home Electricity Bill, interfacing with the Electricity companies, so you don't need to get a 2nd private electricity contract just for your collective carpark slot charger, in addition to your appartment's contract, and you can plug to such chargers anywhere in Europe, still getting the bill for your charge on your home contract seamlessly, whoever that charge belongs to, when set in public places. Also you would like for the public charging slots to have an Androïd App, showing those free arround, those engaged and those un-availble for maintenance, so outside your home you don't spend hours chasing one available to recharge you.

      The demos from other vendors that I saw last year at Paris Motor Show were a pity. Ridiculous small plastic plugs, just good for endless low power charging, with closed to ZERO communications capabilities with Energy companies, and users .....etc. Not serious.

      This one seams promissing with 22KW but need more details. We won't change our home charger every year. Need something built to last with power headroom, but also intelligent !

      This WEB is so precise on EVs that I don't understand why on chargers you stay so un-documented guys. They are key items for our future EV drivers lifes.

        I was curious as well and went to the source. To get the full 22kW requires a 3-phase supply and a 3-phase battery charger in the EV.
        According to Metricmind "The upcoming 22kW (Brusa) NLG644 will be produced in EU and USA versions. It meant to be installed on-board of an EV and will be especially useful for large capacity batteries in trucks, buses, delivery, fleets and similar vehicles".
        Not very likely to be seen in passenger vehicles.

        @nottoosmart,

        Thanks for the key data: the high power is for trucks. The Tesla Roadster's 16 kW on-board charger (240V, 70amps max) is still by far the largest fitted to any BEV car. Someone mentioned technology to reduce the cost of powerful on-board chargers, I can't remember from whom.

        As @uncle_sam says DC fast charging bypasses the on-board charger. Since most electric cars are already handling enormous voltages from the battery pack and brake regen, I think it will be less expensive to add it than upgrading to a beefier on-board charger, and CHAdeMO's 50 kW is more than any AC charging station so far. The IEC 62196 AC spec allows up to 240amps at 480 V (115 kW!), but the Mennekes plug can't handle it and nobody's building any part of the chain that beefy.

        Everything is lined up for DC fast charging — cars, connectors, lots of suppliers, the real-world experience in Japan — except the SAE committee that can't seem to bring itself to endorse CHAdeMO.

      Europe is arguing which INFERIOR standart to use.
      as carl wrote, the connectors are small plasticy LOW and SLOW power charging.

      The German standart features AC charging which is converted by within the car to DC.
      The Chademo protocol takes controll over the car and pumps in DC directly into the pack.
      Chademo seems more efficient to me. Chademo 30min german 180min fast charge.

      Most folks are surpised if I tell about CHADEMO.
      What??? Charging does not take 8 hours but 30 minutes???

      But EVs are supposed to be a bit lame. Because a real FAST charge would make them a real opponent to the internal combustion engine.
      As the europeans don't have an Idea to make REAL evs (only prototypes) they would loos sales of their beloved gas guzzlers.

      oh why....
