China is experimenting with a new form of electric bus, known as Capabus, which runs without continuous overhead lines (is an autonomous vehicle) by using power stored in large onboard electric double-layer capacitors (EDLCs), which are quickly recharged whenever the vehicle stops at any bus stop (under so-called electric umbrellas), and fully charged in the terminus.
Hybrid energy storage can take advantage of super capacitor''s high power density and battery''s high energy density. At the same time, hybrid energy storage cost less. So it''s suitable for micro
Shanghai Green Tech is a capacitors and capacitor energy storage system technology innovator. Since 1998, we mainly focuses on advanced capacitors researching, developping and customizing over 20 years.
Hybrid energy storage systems which combine high-power (HP) and high-energy (HE) storage units can be used for this purpose. Lithium-ion capacitors (LiC) can be used as a HP storage unit, which is similar to a supercapacitor cell but with a higher rate capability, a higher energy density, and better cyclability.
