150 kW CHAdeMO EV Charging In The Works. Yay!

Editor’s Note: For some context, see this “Electric Car Charging 101” article, which mentions that, at the moment, CHAdeMO fast chargers have a max power output of 50 kW, CCS/SAE Combo fast chargers 

have a max power output of 50 kW, and Tesla Superchargers have

a max power output of 120 kW

The war of the EV charging systems is heating up. Today, there are three high-power charging standards. Tesla has it proprietary Supercharger network. The CHAdeMO standard is the one used most often by Japanese manufacturers. The CSS standard is preferred by most American and European manufacturers.

At the moment, CHAdeMO leads in one important area, according to a report from the CHAdeMO Association. The latest data says 33% of new EVs are equipped with CHAdeMO charging, 15% are built to use the Tesla Supercharger network, and 9% are designed with CCS in mind. A surprise in the report is that 38% of battery-electric cars offer no fast-charging capability at all. For PHEVs, 25% are equipped for CHAdeMO charging while 75% do not support fast charging of any kind.

Among manufacturers, Volvo has recently called for one world standard, which it says would lower costs and make customers less nervous about buying an electric car. Tesla sells an adapter that allows its drivers to plug into a CHAdeMO charger, but it also has quietly joined the CSS partnership.

CHAdeMO charging port>To keep itself relevant, the CHAdeMO Foundation is working hard on new high-power charging capabilities. In a statement dated June 1, it said:

[D]uring CHAdeMO’s annual General Assembly in Tokyo, Japan, the Association’s management has announced its plans and ongoing activities towards bringing high power CHAdeMO chargers to the market.

The Association plans to release an amendment to the current protocol, which will enable charging with up to 150kW (350A), this year. The revision of the protocol, announced to the Regular Members already last year, is still ongoing with technical consultations with members happening both in and outside of Japan.

Recognising that the upward trend in EV autonomy will lead to a need for charging with higher power at key locations, especially along the motorways, CHAdeMO mandated its Technical Work Group to tackle issues such as the size of the high power cable or managing temperature increase of the charger that may come in contact with users.

The ‘plug’ itself will remain exactly the same as the current one, meaning the high power CHAdeMO chargers can feed power to both the current EVs as well as the upcoming EVs with higher battery capacity. Current CHAdeMO EVs will also be able to use the 150kW charger, but as today’s EVs are configured to charge at around 50kW, they will charge at the current speed.

CHAdeMO technical representatives are also actively involved in the IEC Committee working on high power charging, where, together with other international experts, they are preparing a revision of the DC high power standards, based on the IEC standards published in 2014.

The Association announcement went on to say, “In terms of higher power, for example 350kW (1 000V x 350A), technical studies are ongoing and the Association will determine its further development around 2018, should there be market demand.”

Porsche has already said its Mission E 4-door electric sports car will support 800 volt charging. Since Porsche is part of Volkswagen, it is safe to assume that future cars from VW will also be capable of super-fast charging. Tesla is experimenting with glycol-cooled charging cables that will not overheat when higher voltages are applied.

Super-fast charging is being pursued aggressively in the world of commercial vehicles. It appears the passenger car segment is not far behind. From the beginning of the electric car revolution, which many claim began with the introduction of the Nissan LEAF in 2010, the time it takes to recharge an electric car has kept many potential customer from buying one. Who wants to hang around a charging station for an hour or so when conventional cars can gas and go in 5 minutes or fewer?

Faster charging speeds will go a long way toward overcoming customer resistance to electric cars.

    I would hope that if they create a universal standard, that they pay attention to thwarting thieves that will steal the copper. There have been cases where thieves have removed all the copper wiring from parking lot lighting and other sources. I”m reminded when pay phones had just a normal plastic clad wire connecting the handset to the box. Now they are all in steel wound sheathing. The last thing an EV driver needs is to count on a charge off the interstate only to find that it is out of service due to thieves.

    May the better standard win… ah no, that’s not it.. may the more advanced standard win.. ah no, that’s not it either.. may the most open standard win.. hm..not it either.. ah, now.. may the biggest group, with the most influence and deepest pockets and (probably) worst technical version win this.

    Crap.

  • Tom Capon

    Title should read “150kW”… I think the number of stations in the works is very different.

  • Marcel

    Yay more standards… instead of one standard.

    • sault

      If Tesla can make a Chademo adapter, we might see a similar adapter for CCS vehicles to use Chademo as well and hopefully vice-versa. It’s a sub-optimal and stop-gap solution, but it is the most likely as automakers continue to avoid working together on one standard. Or until Tesla opens up their network to other manufacturers’ vehicles.

      I always wonder why DC fast chargers just didn’t come out with a standard

      plug on the charging station and drivers could just bring their own charging cable that plugs into this standard DCFC outlet and also matches the charge port on their vehicle. It’s a lot easier to upgrade / standardize a cable than the entire DC fast charge station.

      • Tom Capon

        Umm, that is exactly what they did. Except the plug by itself doesn’t help, they also have to standardize the data sent over the plug. The *only* change to the standard mentioned in the article is to the data protocol, because when they first made it they were too short-sighted to include support for higher rates. Now they have to go back and amend it so that new cars and new chargers will know how to negotiate for the higher charge rate.

        Tesla opened their charging system to other EVs. No one has chosen to use the Tesla system.

    • GCO

      I think you need to read the article…

    • Brunel

      Wow. Why the hell should not the Model X have a CHAdeMO socket along with a Tesla socket!

      • Bob_Wallace

        Probably because Tesla wanted rapid charging now (and back in 2012) rather than waiting for another system to get up to speed.

        • Brunel

          You can have a CHAdeMO socket on the other side of a Tesla. Or they could have the socket behind the rear number plate.

      • GCO

        Tesla offers a CHAdeMO adapter.

  • John Norris

    Tesla originally 90kW, now 120kW

    Chamedo: 50kW?

    Combo/CCS: no idea!

    Yummy!

    I think there are 2 different CSS plugs. CSS USA and CSS EU.
