Part of the reason electric vehicle car batteries are so expensive and bulky is that the batteries deteriorate as they are used, especially when exposed to extreme temperatures. Because of this, automakers often augment them with cooling and heating systems, and add extra battery cells to offset losses in performance over time.
Ultra capacitors (also known as Super Capacitors) can sidestep this problem, because they can be recharged without degrading and can work well in a wide range of temperatures. Ultra Capacitors are considered an environmentally friendly solution because, unlike batteries, they can perform reliably through a million or more charge-discharge cycles in all weather conditions without having to be replaced and disposed of in landfills.
With low internal resistance, Ultra Capacitors have high power density to meet instantaneous power needs. Ultra Capacitors enhance the performance of hybrid and electric vehicles by meeting the electrical power demands of acceleration, power steering, electrical systems, starter system and board net stabilization, and they play a significant role in Start-Stop and regenerative braking systems solutions.
