ABB launches 150-350 kW DC fast charger

Electronics giant ABB’s new Terra HP High Power Charge system is designed for use at highway rest stops and gas stations. Terra HP’s ultra-high current has the capacity to charge both 400 V and 800 V cars at full power.

The 375 A single power cabinet can charge a 400 V car at 150 kW continuously. Dynamic DC power sharing allows a two-power cabinet charging system to charge a pair of EVs simultaneously, at up to 350 kW and 500 A, while dynamically optimizing the available grid connection. Additional power cabinets and charge posts can be added after installation.

Terra HP features individually cooled charging cables and redundant power and communication connections. ABB Ability Connected Services facilitates the connection of chargers to back offices, payment platforms and smart grid systems, and provides remote diagnostics and over-the-air software updates.

    Can someone describe how this plays with the CCS and CHAdeMO standards? In other words, I believe those standards are only applicable to 50kW today, correct? Have the standards been officially extended to 150kW? Is ABB (and other charging station manufacturers) going out on a limb to support 150kW and potentially risking being incompatible with other vendors’ and vehicles’ 150kW solutions?

      Both CCS and CHAdeMO standards are upwardly and downwardly extensible – so existing and future EVs can charge to stations whether 50, 150, or 350 (although current models may not do the higher power, they can still get the 50kW of juice from a faster station). That’s the beauty of open standards over proprietary protocols. My understanding is that at the moment CHAdeMO allows for up to 150kW / 200 amp and latest CCS goes up to the higher 350kW level (for now).

        I did a little more digging on this. I’m more interested in what has officially been ratified as a standard vs. just making a statement of “ready” or “possible”. In my industry (not auto related) standards take awhile to be ratified and more than once a company has been caught out implementing a “proposed” standard only to have it not be 100% compatible with the actual released standard. This is even more important with EVs because if these ABB stations do not work with future cars that were designed to an actual future ratified standard, that could be a problem. I realize that if ultimately the commands from the car to the charging station are to simply request a certain voltage and current, that a charging station with components spec’ed to handle higher voltages/currents/power levels could in theory be considered “compatible” with hypothetical future higher power vehicles, but I worry about what happens if during testing and development of new higher power standards they decide they need to introduce a new command or charging mode, to avoid overheating for example…

        Anyway, it appears that CHAdeMO (which is not technically an open standard–you have to join the CHAdeMO consortium to get the specs) is currently limited to 500V @ 125A or only 62.5kW. As you said though, it is “ready” for 200A, bringing the power level up to 100kW. So directly to the point of my question: since the picture in the article shows what I assume to be a CHAdeMO connector, if I were to plug a hypothetical higher power CHAdeMO vehicle into this charging station, would it be limited to 125A? 200A? 375A to give the stated 150kW for 400V vehicles? There was a proposed amendment announced last year that stated support of up to 150kW (really 350A @ 500V, so 400V cars would really only receive about 140kW), but I’m not aware the amendment was necessarily ratified. Still, it would be hard to imagine that ABB would not have designed this charging station to be compatible with at least the proposal.

        CCS is a bit different, but somewhat the same. The connector at least is already spec’ed to well above these power levels. It seems that the official standard may be limited to 125A @ 800V (only 100kW, and that’s for an 800V car!), but that it too should support 200A operation (80kW for a 400V car). But this is somewhat dated information, so perhaps things have firmed up. 150kW capability was announced in 2015 by the Charging Interface Initiative which is made up of a subset of the automakers that use CCS, so it’s not clear to me whether this is formally part of the standard or not, although again, it’s pretty likely that ABB was probably working off this spec.

        Without clear information that this charging station (and any that work over what appear to be the officially ratified standard limits) is operating to a fully signed off spec, I have a worry in the back of my mind that we will run into incompatibility issues in the future. This has happened with even the relatively “simple” J1772 standard chargers, so who knows about high power DC fast chargers!
