This is good news. But, why don't EVs have a standard to follow like gas cars have a standard fill port? It seems like there is a lot of proprietary tech going on in the EV market at the moment, like early 2000s cell phones that all had their own unique charging port. Edit: Thank you for your replies! I'll look into the CCS EV plug.

The reason is because it’s new - there’s no clear winner for what’s the best, and not getting the standard right would likely mean the downfall of EVs. CCS is looking good and Europe has effectively forced it upon manufacturers, though.

  The Tesla adapter is MUCH smaller: https://teslatap.com/wp-content/uploads/2020/06/connector_comparison.jpg https://teslatap.com/wp-content/uploads/2020/06/connector_co... The Chademo and Us CCS plugs are terrible. Objectively bad (expensive, heavy, etc). The European CCS plug isn’t quite as good as Tesla’s but is probably good enough. The Us should adopt either Tesla’s plug or the European plug.

    Why is CCS so big compared to the Tesla one? Why does one plug have to connect to both AC and DC even if you're using only either one?

      One is designed by committee, the other is designed by a company with a focus on trying to make electric cars more usable and desirable than fossil cars. Also, CCS wanted to reuse some of the pins from the L1/L2 J1772 plug, but the original plug didn’t have room for larger pins. Tesla’s plug was designed from the beginning to be eventually capable of fast charging.

There is a standard for EV charging ports: CCS. Unfortunately, there's a competing standard: CHAdeMO and Tesla being the first mover has their own proprietary connector.

  Yowza, there's a CCS adapter for Teslas, but it's $600 and really big: https://www.setec-power.com/ccs-adapter/ https://www.setec-power.com/ccs-adapter/

In the US, it's CCS. Manufacturers that supported Chademo, like Nissan, are switching to CCS. At this point Telsa is the only non-CCS manufacturer.

  That's cool, it's good that there is some convergence on a standard. The only unfortunate thing, then, is that Tesla had 79% of the EV market share in the US in 2020 (cf. https://electrek.co/2021/07/14/tesla-tsla-leads-95-increase-electric-car-sales-us/ https://electrek.co/2021/07/14/tesla-tsla-leads-95-increase-...). And they are not using CCS. (edit: CCS... not CSS)

That's not right, the only "proprietary" connector is Tesla's, every other connector is completely open. Tesla claims theirs is open, but clearly not enough for others to adopt it. The non-Tesla connectors, none of which are proprietary or unique to a manufacturer: * J1772 "Level 2", the slower 240V AC that's common for home charging (this was incorrectly labeled as "type 2, thanks for the correction jsmith45) * CCS - fast DC charging, the form factor is Type2 plus a bit of an extra shape. * CHaDEMo - a separate fast DC charging connector

  Also, CHaDEMo is only still being used on one or two new models in the US. Everyone else (except Tesla) has adopted CCS on vehicles that support fast charging.

  Don’t underestimate the “Not Invented Here” syndrome for why other carmakers don’t use the vastly better Tesla adapter. This image shows the size difference: https://teslatap.com/wp-content/uploads/2020/06/connector_comparison.jpg https://teslatap.com/wp-content/uploads/2020/06/connector_co...

    Those same carmakers didn't invent CCS either. So by the same logic they'd be skipping the non-proprietary CCS standard just like the proprietary Tesla one.
    - Robotbeat 5y ago
      No, but they’d rather pick a 3rd party standard than acknowledging the value of their main competitor’s innovation.

        That wasn't the argument you made above.
