Charger counts are updated quarterly by combining CEC voluntary survey results with public and shared private chargers listed by the Alternative Fuels Data Center (AFDC) and PlugShare. Visit full page layout of dashboard, download data, or return to the dashboard collection page.

Definition of Terms

Chargers, often referred to as electric vehicle supply equipment, are manufactured units that safely deliver electricity to charge the battery of a plug-in electric vehicle. A charger may have one or multiple connectors.

Public chargers are located at parking space(s) designated by a property owner or lessee to be available to and accessible by the public.

Shared private chargers are located at parking space(s) designated by a property owner or lessee to be available to, and accessibly by, employees, tenants, visitors, and residents. Examples include workplaces and shared parking at a multifamily residence.

Private chargers are located at parking space(s) that are privately owned and operated, often dedicated for a specific driver or vehicle (for example, a charger installed in a garage of a single-family home).

Charging Station is a physical address where one or more chargers are available for use. A charging station can be public, shared private, or private. 

Level 1 chargers use alternating current electricity at 120 volts to provide about 5 miles or less of range per hour of charging.

Level 2 chargers use alternating current electricity to charge a plug-in electric vehicle at 208 to 240 volts and can provide about 14 to 35 miles of range per hour of charging.

DC Fast chargers use direct current (DC) electricity at 480 volts to recharge an all-battery electric vehicle to 80 percent capacity in about 30 minutes, though the time required depends on the size of the vehicle battery and the power level of the charger.

Counting Method: The number of chargers represent the number of vehicles that can charge simultaneously. For example, a Level 2 charger with two connectors that can charge two vehicles simultaneously is counted as two chargers. A DC Fast Charger with two connectors that can charge one vehicle at a time is counted as one charger.

Data Collection Information The CEC voluntary survey is sent to electric vehicle network service providers, utilities, and public agencies in California. The surveys collect data on shared private chargers (typically found in workplaces, multi-family housing, and other non-public venues) in the state. The AFDC station locator contains data on all publicly available chargers in California. PlugShare is a commercial database and smartphone application that also has shared private station information.
