Its very important to standard committee to jump in the initial stages of any technology development that is going to impact many humans. Soon we will have more concise and clear standards for EV car manufacturers.
The opening claim that standards development is a sign that the electric vehicle market is maturing is very disconcerting given the current status of the market and especially sales where we see established automobile manufacturers struggling to stay in the EV business. Standards are very important in enabling consumer acceptance but do not necessarily indicate a mature industry. Hopefully, standards here will help EVs gain traction in the market and we'll see greater acceptance.
ANSI itself doesn't develop standards. We accredit the procedures of standards development organizations like SAE International where battery manufacturers and other subject matter experts determine the technical content of the standard. The ANSI EVSP roadmap identifies an interoperability gap with respect to the dimensional and mechanical aspects of batteries in the context of battery swapping stations.
You've hit on a key theme of the roadmap--the need for a widely available charging infrastructure. Also identified as a gap is the need to complete work on fast charging standards. The ANSI EVSP roadmap identifies the standards and related conformance programs needed to achieve the safe, mass deployment of EVs. That will only happen if EVs meet consumer expectations for safety, affordability, interoperability, performance and environmental impact. Standards are key to consumer acceptance and the growth of this industry.
Unfortunately there are so many types and sizes of batteries are in the market along with that a variety of vehicles with different sizes and power are available in the automotive segment. I think it will be too early for ANSI to come with a standard that can be made acceptable to all the manufacturers.
The current delivering capacity of the EV charging source is a topic that I don't often hear discussed. At plug-in, the vehicle and the outlet must compare their relative capacities and then identify the optimal combination. Pure electric cars (e.g. Fisker Karma) may be able to accept much more power than is available from many circuits. This means that they'll charge slower than they could have. When public EV systems are being wired, they should plan ahead for higher charge rates in the future as battery technologies improve. High source amperage is a key factor.
One of the important factors is consumers need somebody to tell them that their brand new vehicle won't be obsolete a couples year from the time of buying. Interconnect and charging related standards will definitely help consumers to build confidence. IMO, the most crucial driving factor is the wide availability of charging stations. Quick charging time will definitely help as well. I am spoiled. I don't want to stand in the charging station for 20+ minutes to get my car charged up.
What's your criteria of acceptance of EV vehicle?
Technical standards are not gee-whizzy, but they are essential to deploying new technologies. Cleantech and electric vehicles are a case in point. Once more standards are in place, we'll begin to see more EVs on the road.
