Understanding the load
Level 2 chargers commonly draw in the range of several kilowatts each, and DC fast chargers far more. A parking area with many chargers can add a substantial load to a building service.
Load management and phasing
Load management systems can share available capacity across chargers, reducing the required service size. Many owners install conduit and spare capacity now and add chargers over time.
Coordinating with the utility and site
Service upgrades may require utility coordination, and transformer and switchgear locations affect site layout. Addressing these early prevents costly redesign once the site plan is set.
