In this article, I discuss the primary reasons why autonomous vehicles are emerging, what factors go into developing self-driving cars, and how energy storage is a vital part of autonomous vehicle design.
Well soon start to see a hybrid energy-storage solution of batteries and ultracapacitors to address multiple applications simultaneously, like e-turbo, active suspension, regeneration, power steering, electric brake boosters and more.
Ultracapacitors have other significant advantages compared to batteries such as high power density, high efficiency, long service life, predictable aging, wide operating temperature range and light weight.
In general, ultracapacitors are great solutions whenever the power demand is high, but the duration is short. For example, we are expanding into the diesel truck market, where the high power demand of engine starting can place a great strain on the batteries, greatly lowering their useful life.
Batteries have high-energy capability while ultracapacitors have high power capability. In an optimal hybrid storage system, both technologies could be combined in a way that maximizes the benefits of both.
Compact in size, ultracapacitors can store an incomparably higher amount of energy than conventional capacitors. Indeed, ultracapacitors are currently available on the market with capacitance ranges up to 2700 Farads, and they can release that energy at both a high or low rate.
Sierra was the first to introduce a combination volumetric vortex and multivariable mass flow meter in 1997. Today, Sierra's completely redesigned InnovaMass® iSeries™ 240i/241i builds on two decades of success measuring five process variables for gas, liquid and steam with one connection. Now, with the latest hyper-fast microprocessors, robust software applications, field diagnostic and adjustment capability, and a new state-of-the-art flow calibration facility, Sierra's vortex iSeries delivers precision, performance, and application flexibility never before possible.
