This article written by Adrian Thomas, KYOCERA-AVX Components Corporation, discusses use of supercapacitors in electric vehicles. The improved performance and practicality of electric vehicles (EVs) have merited them a permanent foothold in the overall automotive market.
With higher energy densities, next-generation capacitors could enable greater use of fast-charging capacitors for devices that need long-term storage such as electric vehicles. Capacitors could also provide fast, on-demand power for the grid or private industrial uses.
By judiciously applying supercapacitors to both the vehicle side and the charging network side of the equation, the goal of completely switching to EVs becomes a more realistic scenario. On average, supercapacitors have energy densities of around 8-10 Wh/kg. The energy density is far below the 200 Wh/kg of a typical Li-ion battery.
Commercially available supercapacitors already span a wide range of performance metrics for automotive applications. KYOCERA AVX — a leading worldwide manufacturer and supplier of a broad line of active and passive electronic components and interconnects — offers several reliable supercapacitor options for EVs.
Outside of the vehicle itself, there exists a clear need to improve the charging network infrastructure and use a smart charging principle to help manage energy demand. A hybrid application of supercapacitors and batteries could be particularly beneficial in solar and wind farm applications where the available energy is unpredictable.
Supercapacitor or ultracapacitor A super capacitor, also referred to as an ultra-capacitor (UC), is a storage mechanism with a high energy density. It has a similar design to a conventional capacitor and performs similarly, however it has a higher capacitive value in kilo farads.

Live ChatAs for capacitors, they hold less energy and also they don''t maintain the same voltage as they discharge, so you''d lose speed as the capacitor runs out. A battery powers the car the same at 100% as it does at 5%, a capacitor doesn''t. Perhaps some circuit could fix this though, idk I''m not an electrical engineer.
