With ultra-capacitor, even though the range was limited to 15 – 25 km, the ultra-capacitor last 1.5 million charging cycles within least favorable conditions, which can correspond to 25 years. From the simulation, it is shown that to cover 1 trip, it is necessary to charge the ultra-capacitors 4 times.
What this means in practice is that they: For a lifespan comparison, consider that while electrolytic capacitors have an unlimited number of charge cycles, lithium-ion batteries average between 500 and 10,000 cycles. Supercapacitors and ultracapacitors, however, have a lifespan ranging from 100,000 to a million cycles.
