I am trying to find storage systems that outperform batteries in their capacity. I even considered 100V supercapacitors. I find that there is no difficulty in controlling the output voltage using off-the shelf regulators, but their capacity-to-weight ratio turned-out to be miserable. I have found higher energy density capacitors, but their operation voltage might pass the 10,000 Volts, and I'm unfamiliar with adequate switching devices. Even IGBT switches might fail at these voltages and shortcircuit the capacitors. If a storage device that powers an electric vehicle is short-circuited and has no circuit-breaker, it becomes very dangerous. What other techniques are used to controle such high-voltage discharges? To avoid capacitors leakage current, is there an alternative storage system that retains electric charge using the ion-trap principle or charged water?
Re: Is there a high-voltage powerstorage system, and how it is handled?
