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.
We'll 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.
EDF Renewables offers the same innovative solutions that maximize the performance of our own 5.2 GW of installed projects. Because we're not an equipment manufacturer, our recommendations are transparent and data-driven. We cover the entire project lifecycle: from pre-commissioning support, through warranty and post warranty operation, to late stage and decommissioning.
