OES-4 EV Owners Web Protocol

Start of Block: Introduction

Q2 Thank you for taking the time to complete our web protocol today! 

For the purpose of this research, we are only interested in EVs that plug into the electrical grid. We will be focusing on battery electric vehicles (BEVS) that do not use any gasoline and plug-in hybrid electric vehicles (PHEVs) that use a combination of gasoline and electricity.  

Your responses will be protected as confidential information. According to the Paperwork Reduction Act of 1995, an agency may not conduct or sponsor, and a person is not required to respond to, a collection of information unless it displays a valid OMB control number. The valid OMB control number for this information collection is 1905-0186. The time required to complete this information collection is estimated to average 10 minutes per response, including the time for reviewing instructions, searching existing data sources, gathering and maintaining the data needed, and completing and reviewing the collection of information. If you have any questions or need additional information about this research project, contact me at (xxx) xxx-xxxx, or by email at Gerson.Morales@eia.gov.
