SECTION 9: ELECTRICAL POWER DISTRIBUTION
Utilities may have some control over and access to the energy stored in electric vehicles attached to the grid.
Get QuoteMost modern secondary networks are operated at AC rated voltage of 100–120 or 230–240 volts, at the frequency of 50 or 60 hertz. Operating voltage, required number of phases (three-phase or single...
