No thats how many watts would be needed for todays battery technology . These would be different ,quantum, battery technology.

I call balderdash on that one. You can't cheat the laws of physics.
You still need to push electrons into the storage somehow, regardless of how they're stored. Energy flow is measured in Watts.
To fill a 30kWh battery you need to supply it with 30kW for an hour, or 60kW for half an hour, 120kW for fifteen minutes, 360kW for five minutes, 1.8MW for one minute, or 3.6MW for 30 seconds.
A typical domestic electricity supply is 80A at 240V. That's 19.2kW in total.
To do 3.6MW at 200A would require a voltage of about 18kV. That's the sort of voltages used on the local distribution network to feed substations. (Actually most town substations are fed by 6.6kV.) You're talking seriously dangerous voltages and huge cabling.
