Fast charge developers kit speeds ultrathin supercapacitor prototyping

March 20, 2015 // By Paul Buckley
Paper Battery Company, developer of a supercapacitor-based energy storage and battery enhancement technology, has released a Fast Charge Developers Kit for the company's PowerResponder product line.

The kit enables product designers to incorporate fast charging PowerResponder cells in their products allowing them to prototype a variety of input charging devices and protocols.

With the Fast Charge Developers Kit, PowerResponder cells can be fully charged in less than five minutes.  A 'charge in minutes to run for hours' capability is  attractive for applications such as power tools, toys, Bluetooth headphones, medical and industrial handheld devices and game controllers, where intermittent use cycles allow for rapid recharge in between uses.

“Anxiety over battery life is a major issue for users of all types of consumer and mobile devices.  In addition, larger and larger batteries are being built in to systems with increasing safety risks,” said Shreefal Mehta, CEO of Paper Battery Company.  “By fast charging and recharging the energy storage device in minutes to allow hours of runtime and replacing lithium batteries with supercapacitors, we are bringing exciting new tools to our customers so they can rethink energy management and provide an anxiety-free, battery-free customer experience.”

Charging of lithium batteries (the company notes) is slow, needing hours even for small batteries, and fast charging is limited because of safety issues.  The PowerResponder product line claims to have a much higher energy density than traditional supercapacitors, and can charge in minutes with none of the safety risks of lithium batteries. PowerResponders can be used in parallel with lithium batteries in external packs to enhance the charging rates and can also replace the lithium batteries in some cases. The PowerResponder cell could replace the lithium battery pack in the external power case sold for smartphones today, and provide two hours of talk time extension in two minutes of charging the external power case.  

The Fast Charge Developers Kit is available now from Paper Battery Company for $400 and includes a fast charger board, a user manual, technical support for optimising the charging protocols and two 350F PowerResponder cells. Product
