Taiwan Invests Millions in Development of new Battery Technology & Hub Motor

HSINCHU, Taiwan – Taiwan’s environmental problem is clear to everyone who has visited the island. Too many polluting scooters. To change that the country’s research institute ITRI is developing new electric motors and new battery technologies. This year’s Taipei Cycle will show the results.
Taiwan has more than 12 million polluting scooters for a total population of 23 million! To bring pollution levels down the Taiwan government is urging its citizen’s to turn to (electric) bicycles and is also investing millions into turning the 2 and 4 stroke scooter engines into electric ones. This year’s Taipei International Cycle Show will feature the results of the multi-million dollar investment the Taiwan government has made in its ‘Green vehicle Development Program’.
As Taiwan aims at becoming a global industrial partner for green vehicles, it is focusing on getting the right products in place. All of this is to establish the country as the world’s leading high-tech products supplier. Bike Europe visited the country’s Industrial Technology Research Institute and was introduced to a super slim hub motor for electric bicycles, as well as to the STOBA technology for lithium batteries.
At ITRI some 60 engineers are devoted to the development of new battery technologies. Their first major accomplishment is STOBA. This stands for Self-Terminated Oligomer with Branded Architecture. Simply put, it is a new polymer developed by ITRI that effectively prevents lithium batteries from exploding when damaged, as has occurred in several high-profile cases in recent years. Those incidents took place with laptop computers, where lithium batteries are commonly used. Nowadays, they’re also found in higher priced and better quality e-bikes. And with iPhones, iPads, and tablet computer sales soaring; all of which are all fitted with lithium batteries, it’s clear that the STOBA technology is very valuable.
Another major accomplishment by ITRI is the development of a super-slim hub motor. According to the research institute it is 50% lighter and 70% thinner. As well, the new motor produces two to three times the torque generated by traditional units of the same weight, with comparable production costs.
The new motor features Axial Variable flux technology. This technology is based on the principles of electro-magnetism and permanent magnetism, which not only contributes to the motor’s power but also to the motor speed control.
More on STOBA and the Axial Variable flux technology is in Bike Europe February edition which will arrive this week at its international readership.
