PowerResponder™ Application Note #150301
PowerResponder™ Fast Charger Kit
Reference Design and Quick Start Guide
The Paper Battery company is pleased to provide a fast charger evaluation platform for the PowerResponder
TM
line of supercapacitors. The kit contains a wall adapter, fast charge board and reference circuit diagrams as
requested and includes two PowerResponder™ cells. The kit will enable customers to quickly and effectively
evaluate PowerResponder
TM
and provide design guidance when integrating PowerResponder
TM
cells into their
products.
NOTE: This kit cannot be used for charging lithium-ion batteries, which are unsafe under fast charge conditions
Theory of operation:
The PowerResponder
TM
product line is a hybrid, high energy supercapacitor and can be charged at much higher
current in less time than conventional lithium ion batteries. The Paper Battery Company has data on cycle life
impact showing thousands of cycles with less than 20% loss of capacitance. PowerResponder
TM
devices fail in
open circuit mode after a gradual, easily measureable, and thus predictable, decrease in capacity. There is no
risk of flammability or thermal run-away from the PowerResponder
TM
cells.
Our fast charger kit includes a standard off-the-shelf 36 Watt AC line adaptor providing 18 Volts at 2 Amperes.
The charging subsystem is a microprocessor controlled CC/CV buck converter with an integrated LED fuel gauge.
