Battery supercapacitor hybrid design

In summary, the individual is seeking opinions on using a supercapacitor in their circuit to prolong battery run-time. However, the load drains the supercapacitor faster than the battery can charge it, causing the load to run out of power and restart. The individual is wondering if there is a way to limit the load's consumption or increase the battery's charging speed. They have also decided to purchase a chip from LT to address the issue.

hello! i would like to ask for your opinions. i have tried using supercapacitor in my circuit to prolong its battery run-time. I have attached a simple circuit design for your reference.


the problem is that the load drains the supercapacitor faster than the battery charging the supercap. the result is that the load runs out of power and restarts. is there a way we can limit the consumption of the load or increase the speed of charging time of the battery?

thank you!

If I understand your question, then your battery has too much internal resistance for the load.
You need to select a battery that can accommodate the average current.
The supercap may or may not extend the battery life depending on the load specifications.
 

1. What is a battery supercapacitor hybrid design?

A battery supercapacitor hybrid design is a type of energy storage system that combines the advantages of both batteries and supercapacitors.
