Why NOT Consider “Demand Factors” for EVCEI?
Development of Demand Factors for Electric Car Charging Points for Varying Charging Powers and Area Types
TRUE Engineering Design for EVCEI under EHSS
Current Demand NOT EQUAL to Summation Loading of EVCEI because
1) Charging Current (Current Demand) of EV is Inversely Proportion to Battery Percentage;
2) Modern Electric Private Car only need to recharge two to three days a week (weekly recharge frequency = 0.29 to 0.43) [Section 4.3 (a) of EPD’s Design Guideline for EVCEI];
3) Modern Electric Private Car have driving range at some 300km after an overnight medium charging [Section 4.3 (a) of EPD’s Design Guideline for EVCEI];
Simultaneous Charging at all the Parking Spaces in a Car Park
Simultaneous is NOT Equal to ALL
