This automotive application example compares the use of batteries, supercapacitors, and hybrids for EV charging and sending status reports to a smart receiver or user/utilities. Using a battery-only system, while inexpensive, offers reliability issues with the need to replace the system every three to four years. Batteries are also prone to thermal runaway or outgassing with frequent disposal issues. Using supercapacitor or hybrid cells offers more than ten years of reliable energy storage with no outgassing over a wide temperature range.
