About

The Electric Vehicle Charging Use Data Specification (specification) defines a common format and process for provisioning, collecting, validating and reporting on data related to electric vehicle (EV) charger deployment and use.

Government and utility funded EV charging station deployment programs are expanding rapidly. Evaluation, measurement and verification of the performance of these public and utility programs requires substantial data collection and processing efforts. A common specification for these data which standardizes input data, processing, and outputs can improve the efficiency and effectiveness of public or ratepayer funded charging programs. Common data reporting requirements across funding programs can reduce compliance burdens for obligated parties.

Specification Overview

The specification is flexible and extensible depending on program specifics and evaluation measurement and verification requirements of the funding organization. It is organized into the core specification which details data collection fields, data validations, and reporting outputs for basic tracking, evaluation and verification uses. The specification also supports extensions that enable additional reporting functionality.

Refer to the glossary for definitions of specific termination used in this specification and an outline of the roles and responsibilities of the entities involved in the data reporting process. The field type and format definitions reference defines the data types and formats expected in data collection fields.

Core Specification

• Registration and Session Data Collection Reference - Format and process for registering participant organizations and funded charging stations and collecting session-level usage data.
• Validation Reference - Validation procedures and parameters for registrations and session use data.
• Reporting Metrics Reference - Common reporting metrics supported by the specification.

Specification Extensions

• Costs data collection [FORTHCOMING] — details data collection fields for funding recipient equipment and installation costs.
• Station reliability [FORTHCOMING] — details data collection and procedures for measuring station reliability.
• Grid impacts [FORTHCOMING] — details data collection and procedures for measuring station usage impact on the electricity grid.

Supplementary Materials

• Data Integration Support provides guidance on how to translate out-of-specification registration and usage data into specification-compliant format.
• Example Program Language for data collection and provisioning requirements set by funding organizations.
• Example data files for each of the data collection field specifications. [FORTHCOMING]
