The charging circuit here uses an ATtiny13A and a MP18021 half-bridge gate driver to charge the capacitor, and also is programmed in a way that allows for three steps for charging the...
These instructions are for charging and discharging an “Super (Carbon) Capacitors”. For charging and discharging standard Energy Storage Capacitors (like the .025, 0.50, 1.0 and 1.5 Farad caps) please
We provided an in-depth guide on this topic, so continue reading if you want to learn more about the Supercapacitor charging circuit!
To charge a supercapacitor efficiently and safely, a proper charging circuit is required. This guide will cover everything you need to know about supercapacitor charging circuits, including:

Supercapacitors typically do not need trickle charge or pre-charge, do not require charge termination and can be constantly topped off. Luckily, most chargers allow termination to be disabled.
When I say Current Eliminating, I mean Current Limiting or Regulated Current.
The amount of time required to charge the capacitor is dependent on the CxR values of each RC circuit. Obviously the larger the CxR the longer it will take to charge the capacitor.
If you have a 2.5v super capacitor, you must NEVER charge it at a higher voltage. If you do, you risk damaging the integrity of the capacitor, or worse, an explosion.
For constant voltage charging it is recommended to use a protective resistor in series with the EDLC. It may be necessary to restrict the current with a protective resistor RP to a specific value Imax.
GreenVolt Home Energy is a leading energy storage equipment manufacturer and integrator based in Poland, serving the European market. We specialize in wall-mounted energy storage batteries, power distribution cabinets, generation-storage integration, hybrid inverters (PV & storage all-in-one), communication battery cabinets with IP54 protection, grid-forming energy storage, PV storage power plants, residential all-in-one storage, and VPP-ready systems. As a full‑service energy storage equipment manufacturer, we also provide containerised BESS, modular battery racks, backup emergency power, and zero‑carbon microgrids. Our advanced lithium‑ion and sodium‑ion solutions ensure safety, scalability, and high performance for residential, commercial, industrial, and utility projects across Europe.
Our modular energy storage portfolio ranges from compact wall-mounted energy storage batteries to 20ft/40ft mobile containers and outdoor all-in-one storage cabinets with IP54 protection. We are a leading energy storage equipment manufacturer, offering communication battery cabinets for 5G/telecom, server racks for data centers, and IP54 rated enclosures for harsh environments. Our stackable design allows flexible capacity expansion, while our grid-forming technology ensures stable off‑grid operation.
