NIST PAP 11, Task 6

Coordinate standards activities for electrical interconnection and safety standards for chargers and discharging, as well as a weights and standards certification and seal

for charging and discharging.

Summary of PEV Codes and Standards status and efforts

All PEV charging station installations are subject to national, State and local buildingand electrical codes. These codes ensure the safety, accessibility, and equipmentmaintenance concerns of PEV equipment users, property managers, utilities, andmaintenance workers. These rules and regulations fall into two categories: electricalcode requirements and building code requirements.

Electrical code requirements cover the safe installation, operation, and long-termmaintenance of the electrical equipment at the PEV charging site.

Building code requirements govern the physical construction and placement of thePEV charging station(s) and cover such aspects as accessibility of the equipment,stall dimensions, building materials, and placement on the property.

A thorough review of all the associated PEV standards and codes have beencompleted and their status investigated

The following sections list the existing and current American standards in placeand/or being developed.

Electric and Hybrid Electric Vehicle Rechargeable Energy StorageSystem (RESS) Safety and Abuse Testing SAE J2464

A major revision of the 10 year old document is intended toupdate the recommend practice to:

Improve test descriptions, procedures and data analysis,incorporating lessons learned from conducting testing.

Include other types of electric energy storage devices (e.g.,electrochemical capacitors) and new types of electrified vehicular designs.
