Electric car enthusiasts are excited about the potential EEStor's as-yet-unseen product known as the EESU represents. An extremely lightweight, low-cost battery that can be charged in minutes and has a functionally unlimited lifetime.

Despite these amazing attributes and the fact that Zenn Motor's (ZNN.V) entire future is based on selling electric cars and powertrains that use the technology, no known working prototype has ever been demonstrated.

Much information lately indicates that this all about to change. EEStor founder Richard Weir has said the company plans to announce third party certification of the product by the end of this month and deliver the first working units to Zenn in the 4th quarter of this year.

Part of bringing the EESU to market involves having the novel device certified by the Underwriters Laboratories (UL). In fact, the UL has announced it is developing new standards for certifying the large batteries of electric cars.

If the EESU was really about to see the light of day, one would think EEStor has begun working with the UL.  I reached out to them for clarification.

"We have received a request to certify EEStor's product," said Priya L. Tabaddor, PhD, Global Energy Services, Underwriters Laboratories, Inc.

Take that as you may.
