Electric vehicles have had sluggish sales primarily due to their limited range and high cost. Worth mentioning – you never know what you may ride one day – is a supposedly revolutionary electric vehicle (EV) battery technology able tol allow many EVs to double their range at the same battery cost that they have now. More importantly, the new batteries are easy to disassemble and repair.
It’s the discovery of NTS Works Inc, the letters N T and S in the company name being the initials of Neal Tate Saiki, founder of the leading electric motorcycle company, Zero Motorcycles Inc. After retiring from Zero last year, Neal has formed the new company in Santa Cruz, California which focuses strictly on technology development.
The NTS Works battery pack is composed of small cylindrical lithium ion cells called 18650 cells. They were originally developed for laptop computers and the standardized size and shape has become the most popular in the lithium battery industry. The price for the cells has been steadily decreasing over the years while the energy capacity has been increasing. According to Neal Saiki, “Everyone in the EV industry has wanted to use lithium ion 18650 cells because they are light-weight and inexpensive, but figuring out how to build packs from thousands of these cells has stymied all the smaller companies in the EV industry. Only the biggest car companies have been able to do this up until now.”
The breakthrough in connecting the cells together was solved with an entirely different way of mechanically connecting cells together with pressure. “It’s similar to the way a flashlight battery is held in place by a spring, however, if you used a spring in an EV battery it would quickly melt due to the enormous energy in an EV battery. It has been incredibly difficult to come up with an inexpensive solution.” says Neal Saiki. The first application example from NTS Works is for an electric motorcycle with a 15 kilowatt hour (kwh) battery pack. This battery has 67% more range than the best electric motorcycle on the market today. It is also shaped in a thin package that allows a motorcycle to have a very low aerodynamic drag at freeway speeds. This will give freeway commuters the ability to ride for an hour on the freeway at 70 mph. NTS Works.
