Plugging in your EV might charge to 40% immediately. When it charges to 80% doesn't matter if it has that charge in the morning. So it probably charges somewhere in the night.
Starting your dishwasher, washing machine dryer on a timer before you go to work, so it runs when energy is cheaper.
This doesn't eliminate the need for storage, but reduces its need.
