We're going to disagree on a lot of this.
• A HPC350 charging station shall support a max. current of 500 A at 500 V at least.
• A HPC350 charging station shall support a max. current of 380 A at 920 V at least.
This is directly from the CharIn specs. Both are required (neither was "taken out")
So a unit that can do both would need to be labeled 920V and 500A?
For the 250:
HPC 250 & 350 units are both required to support 500A, as well as 920V.
The label on both the 250 & 350 should read 920V & 500A?
Just because a charger lists that it is capable of 500A @ 500V does not necessarily mean it is not capable of 500A at 700V.
Just because a charger is not capable of 500A at 920V does not mean it is not capable of 500A @ 500V.
The 500V rating is an important part of the spec for those vehicles using "400V" architecture, and knowing how much power it can provide at the lower voltages is important.
CharIn has specific requirements for 500V charging independent of the 920V rating.
As to the (farfetched) idea of a manufacturer selling a CCS vehicle not capable of charging at the majority of current and future CCS DCFC stations, I just don't see that happening. 800V EVs will be able to charge from 400V stations.
BTW, all EVs already have a DC/DC converter.
The minimum for HPC350 compliance is actually less than <400A @ 920V, it is 380A (see OP3 on the chart.Afraid you are interpreting the spec incorrectly. In CharIn's own words
Does a station rated 400A accommodate the dashed blue line to the right of the 400A line on the chart? No. It does not. Clearly then a charger whose labeling says 400A, 920 V does not "acheive HPC350 Class"
