Following the successful rollout of the first mainstream electric vehicles (EV) in early 2011, a myriad of new makes and models have been introduced in the marketplace. From BMW and Volkswagen to Toyota and Hyundai, car manufacturers catering to consumers of all income ranges are joining the EV movement. Consumer interest is fueled by the high gas prices and the ever-growing green movement.

Municipalities and businesses around the country are working hard to create an elaborate EV charging infrastructure, starting with all major U.S. cities. However, grid outage can cause severe problems for drivers of EVs. Princeton Power Systems provides the solution through its line of state-if-the-art inverters.

Princeton Power Systems batteries and inverters are completely compatible with the various brands, models and charging standards used in today’s marketplace.

Society of Automotive Engineers (SAE) Car Charging — The American Standard
AC Level 1: 120 V, 12 A (1.4 kW) or 120 V, 16 A (1.9 kW)
AC Level 2: 240 V, up to 80 A (19.2 kW)

DC Level 1: 200 – 450 Vdc, up to 36 kW (80 A)
DC Level 2: 200 – 450 Vdc, up to 90 kW (200 A)

CHAdeMO Car Charging — The Japanese Standard
Up to 120 A (50 kW) of DC power

Princeton Power Systems Product Interface for AC Charging
Princeton Power Systems inverters can take over powering AC car chargers in case of grid outages. AC chargers are typically wired to the load panel (rather than directly to the inverter). Subsequently, any Princeton Power Systems inverter can be wired to this load panel with the GTIB platform ensuring continuation of charging capability when the grid goes down using battery power. With the DRI platform, the inverter can manage photovoltaic (PV) and battery power to charge cars.

Princeton Power Systems Product Interface for DC Charging — The Kiosk Solution
The Princeton Power Systems hose can be relocated to an external kiosk or it can be placed on the side of the inverter. The optimal solutions, however, is for the controls and charging hose to be located in an external kiosk, separate from the inverter.

Our kiosk solution provides an easy-to-use touch panel for user control, has bidirectional charging and discharging capabilities and is interfaced through industry standard OCPP communications interface.
