Most super capacitors (supercaps) can be discharged down to 0 V and recharged to their maximum voltage with the manufacturer recommended charge current. A simple voltage regulating LED driver with constant current, usually regulated by sensing a low side, series current sense resistor, then a voltage clamp can be used to charge a super capacitor.
You can charge a supercapacitor by connecting its positive and negative terminal to the power supply’s positive and negative end, respectively. Applying more voltage than the supercapacitor’s limit can damage the component, so you should be cautious. In this case, ensure that the charging voltage exceeds 90% of the capacitor voltage rating.
A common rule of thumb is to limit the charging current to the supercapacitor’s rated current. The charging voltage should not exceed the supercapacitor’s rated voltage, to prevent overvoltage damage. A voltage regulation circuit is necessary.
When designing a supercapacitor charging circuit, several factors must be considered: The maximum charging current is determined by the supercapacitor’s internal resistance and rated voltage. Exceeding this current can cause overheating and damage. A common rule of thumb is to limit the charging current to the supercapacitor’s rated current.
