Which charger are you using (or planning) @John C ?

If you use a compatible charger, you can use any EV

Hi,

thanks for the response. I’m using the latest a Hypervolt charger. 
 

it work is fine with my ID3. Just looks like Polestar is not supported by OVO

I’m afraid Hypervolt chargers aren’t supported either yet.

Yes, the ID3 will be fine as it’s a compatible EV but being a non-compatible charger, the Polestar (as non-compatible) won’t work yet. 
 

I realise it’s of no use to you just now, but if you had a compatible charger, you could use any EV with Charge Anytime
