HVIP ZEPCert Requirement and Other Updates

All vehicles eligible for HVIP are required to be certified at the vehicle level. Zero-Emission Powertrain Certification (ZEPCert) will be an additional requirement for all new HVIP vehicle eligible applications submitted to CARB on or after January 1, 2023, for all applicable zero-emission powertrains and the trucks and buses they are installed in.

Manufacturers are encouraged to start the process of obtaining this certification in advance of the deadline. ZEPCert is a newer certification pathway administered by CARB for zero-emission powertrains and heavy-duty vehicles that helps support end-user fleets and ensures information regarding such vehicles and their powertrains are effectively and consistently communicated to purchasers and accelerates progress towards greater vehicle repairability. More information about this certification is available at

2022 Vehicle Eligibility Readiness

As a reminder, vehicle eligibility applications are being accepted on an ongoing basis. More information is in the Manufacturer Resources section at (see vehicle application forms and instructions).

The timeline from when a complete and accurate eligibility application is received by the California Air Resources Board (CARB) to when the vehicle is available in the HVIP Eligible Vehicles Catalog and Voucher Processing Center (VPC) is an average of 75 days. This includes 60 days for CARB’s review and 15 days for HVIP staff to update the Catalog and VPC.
