How do you design EV charging infrastructure for a commercial parking facility?

EV charging design includes: determining number and power level of chargers (Level 2: 7-19 kW, Level 3 DCFC: 50-350 kW), load calculations considering demand factors and diversity, distribution system upgrades for capacity, load management systems for demand limiting, service entrance capacity planning for future expansion, conduit pathways for future chargers, communication infrastructure for smart charging and billing, and ADA compliance. Consider utility rate structures (demand charges), on-site generation/storage integration, and code requirements for parking structure installations.
