There are three different types of vehicles eligible for the project:

Zero-Emissions Vehicles (ZEV)
Any vehicle certified to zero-emission standards. Vehicles in the ZEV category include electric-drive, all-battery electric vehicles (BEVs) and fuel-cell electric vehicles (FCEVs) up to 10,000 pounds gross vehicle weight rating (GVWR). For the purposes of CVRP, ZEVs are categorized as defined in the California Zero-Emission Vehicle Regulation Sections 1962 and 1962.1, Title 13, California Code of Regulations (CCR). The range extended battery electric vehicle (BEVx) is a regulatory vehicle category that was approved by the California Air Resources Board (CARB) in January 2012 and was included as a zero-emission vehicle type in June 2012 as part of the FY 2012-13 AQIP Funding Plan approval.   

Plug-in Hybrid Electric Vehicle (PHEV)
PHEVs are hybrid electric vehicles that have zero-emission vehicle range capability and an onboard electrical energy storage device that can be recharged from an external source of electricity. In general, PHEVs are vehicles that can be driven using electricity, gasoline or both. PHEVs must have greater than or equal to 30 miles EPA range on electricity alone.

Zero-Emission Motorcycles (ZEM)
A ZEM is defined as either a two-wheeled electric motorcycle meeting the provisions of CVC section 400 or a fully enclosed, freeway capable, three-wheeled zero-emission vehicle.

Vehicle manufacturers must apply for CVRP eligibility with the California Air Resources Board (CARB) and meet a number of program requirements. If all requirements are met, the vehicle is added to the list of Eligible Vehicles.
