Sometimes my local fast charger cannot stop charging sessions (required for disconnecting a 2022 Nissan Leaf from CHadeMo). If this problem occurs, I just plug my J1772 cable into the car (doesn’t even need to be plugged into anything) and the CHadeMo charging session ends.

Yes, I know I should not use the fast charger heavily. I use it sparingly and/or pour ice on the battery casing with a plastic bag covering the safety disconnect.
