Supercapacitor Energy Storage Module with Charge-Discharge Study

Energy StorageEasy-Medium

Approx. component budget: Rs. 5,000 - 9,000

Objective

Study how supercapacitors charge and discharge at different currents and compare their behaviour with a small Li-ion cell.

A bank of supercapacitors with balancing resistors, a constant-current charger, an electronic load, voltage and current sensors and a logger.

Energy storage devices, capacitance and ESR, and applications in regenerative systems and backup.

Arduino/ESP32, INA219, resistors, Excel. Do not exceed the rated cell voltage and never short-circuit the bank.

Built and tested Supercapacitor Energy Storage Module with Charge-Discharge Study; objective: study how supercapacitors charge and discharge at different currents and compare their behaviour with a small Li-ion cell.
Measured and analysed capacitance and ESR estimate and energy and efficiency vs current; wrote the report and presented the results in a viva. Add your own numbers: [x].

Replace [x] with your own measured results. Write only what you really did.
