Over-subscribed panels can be used to maximize the number of EV chargers installed on a site, then as more EVs charge simultaneously, the amperage to each charger will reduce to keep the total power draw within the limit of the panel.

Image

Panel sharing is a strategy to install multiple EV chargers while working within a site’s available electrical capacity.

Image

Over-subscribed panels can be paired with software to create a more advanced load sharing strategy.

Image

EV cable management systems can keep charging cords off the parking surface and reduce tripping hazards.

Image

SAE J-1772 and NACS J-3400 are the two most common charging port styles for electric vehicles.

This EV charger was properly installed with clear floor and wall access for charging.

Image

Bidirectional electric vehicles have many resilience benefits.

Image

This EV charger is located near the home’s electrical panel and a time-of-use (TOU) meter.

Image

Electric vehicle (EV) chargers can be installed at multifamily properties to allow convenient charging access for residents.

Image

Electric vehicle charging ports may vary depending on the vehicle manufacturer.

Image

Circuit sharing is a strategy to share loads between EV chargers; in this example, a 2:1 ratio offers 20 amps to each charger from the same 40-amp circuit.

Image

Hardware devices that control the circuits for EV and non-EV loads can be used as a power sharing strategy for multifamily EV charging.

Image

Circuit sharing can be applied in a 4:1 ratio to maximize the number of EV charging stations installed at a property.
