The city of Kaohsiung, Taiwan, has begun testing the world’s only completely cable-free rail system. Instead of relying on an overhead network of power cables to move them, the light-rail trains employ supercapacitors with wireless charging systems to get them from station to station. Taiwan partnered with Spain-based company Construcciones y Auxiliar de Ferrocarriles (CAF) to build the trains, which can charge in only 20 seconds. Tecate Group is a distributor and integrator of Maxwell supercapacitor cells and modules.
Analog semiconductor designer ALD has introduced a series of MOSFETs to balance supercapacitors being used in high-voltage commercial applications.

Vinnie Rossi, known for revolutionizing audio equipment through his use of batteries in his Red Wine Audio brand, has introduced a new audio unit called LIO. Instead of using batteries in his latest product, Rossi chose to use ultracapacitors as the power source. Rossi attributes his decision to the ultracapacitors' longer life, higher current, faster delivery, and greater user-friendliness. Not only does the new LIO unit enjoy those ultracapacitor benefits, but the unit is also incredibly flexible and fully customizable. This is also true of the standard and custom ultracapacitor cells and modules produced by Tecate. The LIO serves as further proof that ultracapacitors are indeed the power source of the future.
Automatic meter reading, or AMR, is the technology of automatically collecting status and consumption for electric, gas or water meters. The data collected is then transferred to a central location via wireless network. This technology eliminates the providers the expense of periodic trips to each physical location to read a meter, and also allows them to provide real time billing and usage information to end users. Since the data is transmitted via a wireless network, burst of energy is needed during the transmission cycle as well and backup energy needed in case of a power outage. Therefore most of the AMR manufacturers have looked at incorporating an ultracapacitor solution within each device to satisfy this demand. Tecate Group with its broad range of ultracapacitor products offer a variety of standard and custom cells and modules with extended temperature range which are currently used within this industry.
