The Vehicle Electric Container (VEC) is a standardized data model that facilitates the exchange, collaboration, and archiving of electrical network, wiring harness and wiring harness component information in the automotive industry. It serves as a tool-independent digital representation of a vehicle's electrical system, supporting the conceptualization and design of logical mockups, the exchange of component data or the product specification of wiring harnesses. The VEC helps ensure traceability throughout the lifecycle of a vehicle's electrical system.

Developed under the guidance of the VDA and the prostep ivip Association, VEC is a standard in the automotive industry, and is published as VDA 4968 and PSI21.
