Multicast means the AP has to deliver a copy of the packet to every other client on the network, so it’s multiplicative.
The router doesn’t automatically know which clients are listening to a given multicast address and which aren’t, so it has to send a packet to all of them.
My guess is it’s sending multicast messages in a hot loop trying to communicate with an app or other IoT devices on the network and freaking out because it’s not getting a response.
All the messaging about fast charging speed is focused on the wrong thing. EV drivers should be able to do the vast majority of their charging at home or at their destination. The messaging should be about getting chargers in more homes, apartment complexes and workplaces. Speed doesn’t matter as much if you’re going to be parked for half the day or overnight. That’s something that gas simply can’t do.
Fast charging stations should only be necessary for road trips, where you should be taking a break every so often anyways.
