What is Vehicle-to-Grid (V2G) technology?
Answer: EVs discharging energy back to the grid during peak demand
V2G enables bidirectional power flow from EV batteries to the grid.
What grounding requirements apply to EV charger installations?
Answer: Equipment grounding conductor, GFCI protection, and proper bonding per NEC
Multiple layers of grounding and fault protection are required.
What site assessment is needed before EV charger installation?
Answer: Electrical capacity, panel space, distance, ADA compliance, utility coordination
Multiple electrical and physical factors must be evaluated.
What is demand response for EV charging?
Answer: Adjusting charging based on grid capacity and electricity demand
Demand response coordinates charging with grid capacity.
What is the 80% continuous load rule?
Answer: EV charging load must not exceed 80% of breaker rating for 3+ hour operation
Continuous loads (3+ hours) cannot exceed 80% of circuit protection rating.
What documentation is required after EV charger installation?
Answer: Inspection approval, manuals, warranty, load calculations, as-built drawings
Thorough records serve regulatory and practical purposes.
