Application
Supercapacitors for Power Assist Systems
Peak shaving and regenerative energy for hoists, AGVs, and cranking.
Power requirements
Peak loads that are several times the average — lifting, acceleration, engine starting — stress batteries and power supplies.
Why supercapacitors fit
A supercapacitor bank supplies peaks and recaptures braking energy, letting the source be sized for average rather than peak power.
Selection factors
- Peak current and duration
- Duty cycle and RMS current heating
- Bus voltage swing acceptable to the drive
- Converter topology
Limitations
- Requires power electronics to manage energy flow
Supercapacitor types
High-Capacitance Supercapacitors
Large cells — hundreds to thousands of farads — for power assist and module building.
