A new standard for charging ebikes is coming? A quick interview with Bosch - charge2bike

Intended Use
Recharging batteries
I had a quick chat with dr Vikram Godbole about "charge2bike", a new standard for charging ebikes. See the interview in the video and keep reading for more details.



The CHAdeMO consortium was formed to create a standard for charging e-bikes. In addition to Bosch, it consists of several e-bike companies such as Shimano, Yamaha, Panasonic and Brose.

Bosch showed us the result at the launch of the new Bosch Performance CX (BDU38/gen5) motor. It was a short cable with the regular Bosch charge plug in one end and the new standard plug in the other end. The cable will of course allow communication between charger and bike, so it’s not just a dumb cable with two different connectors.

Both ends of the proposed new charging connection.


The idea is you can use any standardized charger and connect your brand specific adapter cable to charge your bike. These chargers could be installed in a variety of places, like public bike parking and hotels, or even cafés and shops.

Charger details​

The chargers are rated for 800 W continuous power and up to 2.000 W for shorter durations. Most e-bike systems out there run on 36 and 48 V batteries, but some have gone 24, 43 or 52 V. It seems the charge2bike system can work with all of them as it supports 24-60 V.

A few charge2bike specs, and they're working a solution for electric motorcycles too.

Why do we need the adapter cable?​

Couldn’t the e-bike manufacturers just agree upon a standard plug? Dr Godbole, senior Product Manager for batteries and chargers at Bosch eBike Systems says the plug can’t be used with detachable batteries, the plug can’t be tilted out of the battery.

But couldn’t they just agree on a different design that would work with detachable batteries? I didn’t ask, but to my understanding, the various brands were already too committed to their current designs. And in some ways, that’s okay. Even though standards seem like a good thing, they can hinder development and innovation to some degree.

Does that mean we have a new standard now?​

No, unfortunately not. The charging system is finalized, but it hasn’t been implemented yet. The consortium of course hopes it will become a new standard, but the industry needs to embrace it. And that’s more likely to happen if consumers start requesting it.

It's not just ebikesystem manufacturers behind the consortium, far from it

It’ll happen over time. But it took a few years before our phones recognized the benefits. Evolve or go extinct.

Standardization for our bikes has already been adopted but the electronics and charging hasn’t. Probably baby steps at first …then all the new bikes will soon adapt or adopt.

Of course not, it would mean backward compatibility, battery replacements/substitutions and all that bulls%^t ... we don't want that ...
 
What the hell is wrong with these people? No one wants to carry a stupid adaptor cable around, especially not one that big. And most Cafe's, Restaurants and Hotels etc aren't going to want to shell out the money to install chargers for this (except maybe in very popular ebike destinations).
Sure, it would be great to go to 800W but since Bosch currently won't go above 200W it seems excessive.
Why can't we just have USB PD (Power Delivery)? That will (currently (excuse the pun)) do 180W at 36v and 240W at 48v. Would surely be dead easy to make a SMALL adaptor for existing bikes and slowly switch over to a USB socket for future bikes and batteries.
Small businesses are going to be much more inclined to install USB PD chargers that can also be used by Phones, Laptops and other devices and the economies of scale will make them far far cheaper.
IF, ebikes and scooters etc adopted the USB PD standard then it seems likely the standard will evolve to offer even more power in the future, far quicker than this nonsense is going to get adopted.
 
Good point ! I guess just a small adaptor USB PD -> your bike could be interesting !

As they mentioned, they want to keep proprietary sockets for batteries :/
