Neither article mentions what specs - voltage and kW - are used when doing this very fast charging.

Does anyone know? Assuming it's not just the current high-end spec of 800v? It matters because higher current requires heavier equipment to generate it and heavier cables too.

The other company that makes batteries that charge this fast, BYD, also makes appropriate chargers, which use a somewhat higher voltage, of 1000 V. Those chargers can provide up to 1000 A.

Yes, I am aware that BYD has demonstrated a 1000 kW charging system. In their case it's literally the headline (1) or subheading in other articles (2)

Which is very much in contrast with this article not mentioning these numbers at all. It's odd.

Are you saying that you know that this CATL charger has the same specs despite this? That was my question, really.

I do not know more than is said in this press release, but I assume that they have coordinated to use identical charger specs, otherwise both would lose. It is said that there already are hundreds of such fast chargers installed, so at this point it would not make sense to try to install other incompatible chargers or to make cars incompatible with the existing fast chargers.

I assume that the chargers are more or less compatible with the older chargers, but they must be able to negotiate a higher charging voltage and higher maximum charging currents.

When either the vehicle or the charger does not support the higher voltages and currents, they should fall back to an older and slower charging mode.
