I'm sure I've read that we'll get a discount card on some networks. Obviously though the devil is in the detail so no idea on what charge networks or what the costs would be.
As a rough guide, if we take the battery as 77kWh (and I'll do some rounding here), 10% would be 8kWh and 80% would be 62kWh so you're looking at putting in around 54kWh.
A few prices...
Ionity @ 69p = £37.26
BP Pulse @ 42p = £22.68
Instavolt @ 40p = £21.60
Gridserve @ 24p = £12.96
Obviously those prices are very rough and some networks charge different rates at different places.
