EVITP EV Charging Standards 2

Question 1

What is Vehicle-to-Grid (V2G) technology?

Accepted Answer

EVs discharging energy back to the grid during peak demand

Answer

V2G enables bidirectional power flow from EV batteries to the grid.

Question 2

What grounding requirements apply to EV charger installations?

Accepted Answer

Equipment grounding conductor, GFCI protection, and proper bonding per NEC

Answer

Multiple layers of grounding and fault protection are required.

Question 3

What site assessment is needed before EV charger installation?

Accepted Answer

Electrical capacity, panel space, distance, ADA compliance, utility coordination

Answer

Multiple electrical and physical factors must be evaluated.

Question 4

What is demand response for EV charging?

Accepted Answer

Adjusting charging based on grid capacity and electricity demand

Answer

Demand response coordinates charging with grid capacity.

Question 5

What is the 80% continuous load rule?

Accepted Answer

EV charging load must not exceed 80% of breaker rating for 3+ hour operation

Answer

Continuous loads (3+ hours) cannot exceed 80% of circuit protection rating.
