Voltrek designs and installs EV charging infrastructure that complies with the latest industry standards, codes, and manufacturer requirements. By following proven best practices and supporting leading charging technologies, we deliver safe, reliable, and future-ready solutions built for long-term performance.

 

DC Fast Charging

DC Fast Charging is designed for commercial and public applications where rapid charging is essential. Operating on 208V, 480V, or 600V three-phase power, these systems typically deliver outputs of 25 kW, 50 kW, 150 kW, and higher, providing approximately 100–200+ miles of driving range per hour of charging, depending on the vehicle. Many DC fast chargers are equipped with both CCS and CHAdeMO connectors to support a wide range of electric vehicles. While Tesla vehicles use a different charging standard, drivers can utilize compatible adapters to charge at many non-Tesla DC fast charging stations.

  • 3Phase 208v, 480v or 600VAC

    Gets you about 100-200+ miles per hour charging

    Output typically 25, 50, 150+ kW (and beyond)

    DC Fast Charging is for commercial & public applications.  Performance is similar to a commercial gasoline service station, in that recharge is rapid.  Many units come with both CCS and CHAdeMO charging connectors.  Tesla does not conform to any of the below standards, but Tesla drivers have adapters available that allow them to charge at non-Tesla stations.

  • US Standard for most EVs. Also called the CCS Connector. Combines the J1772 standard with DC Charging in one port. Bidirectional capable.

  • This connector is compatible with most Japanese manufactured Plug-Ins (Nissan, Mitsubishi, etc). Bidirectional capable.

 

AC Charging

AC chargers are designed for residential, workplace, commercial, and public applications where convenient, reliable charging is needed over longer periods of time. Operating on 120V or 208–240V AC power, these systems typically range from 1.4 kW for Level 1 charging to 7–19.2 kW or higher for Level 2 charging, providing approximately 3–60 miles of driving range per hour, depending on the charger and vehicle. AC charging is a cost-effective solution for locations where vehicles remain parked for extended periods of time.

  • 120 volts (AC ), 15-20 amps

    Gets you about 5 miles per hour charging

    Time to charge from empty to full: 8-18+ hours

    All EVs come with a Level 1 charger that plugs into to a standard 3-prong US outlet (15 or 20 amp).  Level 1 chargers use the standard J1772 connector. These are sometimes referred to as “emergency” chargers, and are typically left inside your EV to use a last resort.

  • 220-240 volts (AC), 32-50 amps

    Gets you about 10-25+ miles per hour charging

    Time to charge from empty to full: 4-8+ hours

    Typically 7.2 kW output.  Level 2 chargers use the J1772 connector, which are compatible with all EVs sold in the US.

  • The U.S. adoption of the J1772 Standard ensures all Level 2 charging station connectors will be compatible with all EV inlets found in U.S. vehicles.  This standardized coupler (both the connector and inlet) cleared the way for rapid expansion of EV charging sites.

    The connector is designed to withstand all weather conditions and boasts numerous built-in safety measures.  The plug is never “live” when handled; no energy is released until a safe connection is detected and when disconnected, the plug is immediately de-energized.  An EV cannot move while the J1772 connector is plugged in, ensuring a driver cannot drive away with the cord connected.
