Final - DC EVSE v8.1-1.png


Plug-in electric vehicles are commercially available today with most vehicles only having  Level 1 and Level 2 AC charging capability. AC charging requires on-board chargers within the vehicle to convert AC power to DC power. The use of on-board chargers adds a burden to the vehicles in the form of added size, weight, cost and heat. In addition, AC charging at 240 Volts AC has limitations to the amount of power or Kilowatts that can be delivered to the vehicle. 
These limitations result in lengthy, undesirable charging times to “fill up” the vehicle’s battery. DC fast charging is a method in which the charger is placed off-board and the AC power conversion to DC takes place within the external stationary charger thus reducing burden on the vehicle.
The inverters are UL-Approved and meet UL-1741 requirements for utility connected power inverters. Our chargers are designed to meet ISO 15118 standards. Coritech chargers provide many safety features including over-current protection, ground fault detection and emergency shutdown capability to assure safe and reliable fast charging of electric vehicles.  Our easy to use color touchscreen operator interface guides the user through a simple procedure to initiate each charging session.

Fast DC Charging

Coritech VGI Series chargers provide the fastest power transfer available today for DC charging, limited only by the maximum current capacity of the industry standard SAE J1772-Combo connector.

V2G Support

VGI chargers provide full communications capability for connectivity to utility ISO's. Aggregators and Microgrid Controllers using high speed and secure Ethernet-based protocols. Our chargers are designed to meet ISO 15118 standards.

Vehicle Integration

Coritech provides integration,engineering services, and support to develop hardware and communications integration between the vehicle and charger. Coritech has developed a communications interface that conforms to SAE standards for electric vehicle charging including SAE J1772 and J2847.

Aggregator Control

Coritech chargers provide the ability for each vehicle's charging activity to be controlled from a remote grid "Aggregator" system that manages overall grid performance, health, and stability. Aggregators also can communicate with local utility ISO's for participation in the energy markets.


Provides DC fast charging and reverse power flow (V2G) capability for grid-tie applications to allow vehicles to act as power sources.

VVO - Volt Variable Optimization

Coritech chargers provide the ability to influence the stability of the grid by providing VVO to contribute or absorb reactive power (KVARS) to influence the grid power factor.

DC Charging Level 1 & 2

Coritech VGI Series chargers provide up to 19.2 kW (Level 1) charging with SAE J1772 connectors and up to 60 kW (Level 2) charging with SAE J1772-Combo connectors. Maximum charging capacity of 75 kW with use of military and specialty connectors and cabling.
