The image/text posted below shows that Chargepoint has "Power Management" for shared stations. This allows more lines/plugs than the supply wires/breakers might be rated for. Given that quite often cars are stilled plugged in when fully charged, that seems like a good scheme, allowing more plugs without greatly increasing installation costs (like fat wires).Unfortunately for MiEV owners, I believe the pause in charging is interpreted by Chargepoint as that car being done charging, so the power is sent to the other cord(s), if shared. In my experience, after or during a pause, power seems to be shunted away even when no other car is plugged in.I have pointed out to Chargepoint customer service that this is a problem, but so far there has been no fix to the problem of getting just 1.1 kW after the pause, on dual cord stations. The description below does not state how the power distribution is controlled. I'm thinking it could be by the pulse width of the pilot signal the station sends to each car, or it might be more directly controlled by some other type of power circuitry within the station.
