ANSI releases version 2.0 of EV Standardization Roadmap

The American National Standards Institute (ANSI) has released version 2.0 of its Standardization Roadmap for Electric Vehicles. This lengthy tome seems to address every conceivable standard that has to do with EVs, and it makes a dense but interesting read.

The Roadmap tracks progress to implement recommendations made in version 1.0, released in April 2012, and identifies areas that need more standardization work. It frames activities under three broad domains: vehicles, infrastructure, and support services (shades of Charged’s three departments: The Vehicles, The Infrastructure and The Tech – great minds think alike).

The three domains are highly interdependent. Handy charts illustrate how the various issues relate to one another.

A small sampling of some of the gaps – issues that should be addressed in a standard, code, regulation, or conformance program – identified in the Roadmap:

  • delayed battery overheating events
  • safe storage of lithium-ion batteries
  • battery recycling
  • audible warning systems
  • wireless charging
  • battery swapping (both safety and interoperability)
  • vehicle as supply / reverse power flow
  • standardization of EV sub-meters
  • telematics smart grid communications
  • fire suppression, fire fighting tactics and personal protective equipment
  • labeling of EVSE and load management disconnects for emergency situations
  • electrical energy stranded in an inoperable RESS
  • battery assessment and safe discharge following an emergency event
  • workforce training – charging station permitting
