New development of the large capacity electric double layer capacitor

New development of the large capacity electric double layer capacitor

In the condenser, a long development history is the electric double layer capacitor (EDLC).

Main causes of the large capacity EDLC attention various rechargeable battery fire accidents occur frequently in recent years.

Although these fire accident without lithium ion rechargeable battery design and manufacture of the cause of the error, but I think there are other factors. For example, BMS (battery management system) and ensure the safety of the matter.

Through the control of lithium ion rechargeable battery combination use of EDLC BMS, can reduce the risk of battery fire. Pure electric vehicles and hybrids of automatic welding machine etc. Needless to say need large current. With EDLC can absorb load change sharply, can restrain the degradation of the lithium ion rechargeable batteries, prevent the lithium-ion rechargeable battery fire.

In use for car, there's hope in supporting the fast charging and wireless power supply using the large capacity of capacitor. And in this case, just can produce capacitor than lithium ion rechargeable battery fast charge and discharge, charge and discharge cycle long life characteristics.

In terms of EDLC important technology, has improved in several areas, specific for: (1) high pressure, low resistance technology; (2) low dew point drying room/space technology; (3) high-speed injection fluid technology; (4) automatic reset type safety valve, etc.
