DC Charger Controller for CCS1

Maybe a hint on voltage, current, and expected control range and control signal range might stimulate some interest in coming up with a component level solution. Just because it has a fancy TLA doesn’t mean it can’t be solved with non TLA components.

Thanks for the reply.

The controller is independant from the power section. It only give it the setpoint and run command. The same controller can serve a 50kW DC charger or a 1MW one...

But if you want numbers for my design, here they are:

300kW ultrafast DC charging capacity.

400VDC and 800VDC compatible.

So, still a lot of holes in your information. You got question 1, still need 3 & 4. Plus the battery chemistry, to design the supply current curve and limits. It is likely an ac designed controller will work, with a simple interface adapter. It is not as complicated as you might imagine.

Thanks but I disagree that meeting ISO 15118.2 is simple. It requires complex hardware and software.

Note that the specifics of the DC power electronics is independant from the operation charge controller as long as it is configured properly.

So now we add an ISO specification, complex hardware and software, to conform to your original need for a simple basic controller. What are we missing?

I agree with you that in general, acronyms should be avoided, or at least, defined.

In this case, if you don't know the signification of CCS1, you cannot help me as it is a very specific requirement.

Thanks for your contributions to so many posting. I enjoy reading them.
