Educational guides

Where to start

1. Learn the basics. Charging levels and connector types decide what equipment fits a site.
2. Plan the installation. Electrical capacity, permits and qualified installers.
3. Plan for operations. A charger that is not maintained will not stay in service.

• Charging levels explained: Level 1, Level 2 and DC fast charging

  What the three charging levels mean, how much power each delivers, and where each one belongs.

• Connector standards: J1772, CCS, J3400 (NACS) and CHAdeMO

  The plug types used in North America, which vehicles use them, and what the shift to J3400 means for site hosts.

• Planning a Level 2 installation

  Electrical capacity, permits, code requirements and contractor qualifications for home and commercial Level 2 charging.

• Charger reliability and uptime

  Why public chargers fail, how uptime is measured under federal rules, and what keeps a site working.

• EVSE glossary

  Plain-language definitions of the terms used in EV charging, standards and regulation.
