Depending on the application, S-CAP BOOST can be configured to charge and monitor supercapacitor banks to function as a UPS, providing backup power to allow safety operations to be performed before shutdown, or supplying high peak power for a short period without disturbing the main source or discharging/damaging the system battery in applications such as lasers, electric motor amplifiers, or X-ray emitters.
Critical applications operating in harsh or enclosed environments are strictly regulated in terms of chemical and other hazardous risks, limiting or prohibiting certain types of batteries such as lithium-ion. For safety reasons, these applications must have backup power long enough to execute alarms and safety shutdown processes. In such challenging conditions, conventional batteries are replaced by supercapacitor banks with values ​​ranging from a few farads to 200 farads for general applications, but up to the size of a container for large systems. S-CAP BOOST technology tightly controlsvital parameters, from a single 2.8V cell supercapacitor to a wide range of assemblies that provide the specific voltage and power required for a given application.
One example of a product built using Powerbox's S-CAP BOOST technology is a 2500W backup power unit developed for an industrial process control computer installed in a very confined space. Housed in a 19-inch 2U chassis, the 29F-54V-60A integrates 22 supercapacitors totaling 29 Farads and has a capacity of 2500W for 5 seconds at full load and 30 seconds at half load. To optimize cell charging, the 29F-54V-60A incorporates a DC/DC converter with current control, ensuring that the supercapacitors are properly charged to deliver maximum power when needed. The unit includes active cell load control with load balancing, cell health monitoring, and alarms. Alarm signals, including Vcell-high, Vcell-low, Vcell-zero, and temperature, are available via a physical interface, with digital control and monitoring as an alternative.
Patrick Le Fèvre, Marketing and Communications Director at Powerbox, comments: “The number of applications requiring emergency backup or high peak current is growing, and integrating supercapacitors into power supplies is becoming an extremely reliable and suitable option for system architects to consider. Powerbox’s S-CAP BOOST is a great platform for the future, and we foresee an impressive number of applications for supercapacitor energy storage technology, and not just for electric vehicles.
Compared to lithium-ion batteries, which have a cycle life (number of recharges) of 500 to 1,000, supercapacitors can withstand 500,000 to 20,000,000 cycles, making this technology extremely relevant for applications requiring large numbers of high-energy charge/discharge cycles, such as industrial or medical lasers.” For this purpose, S-CAP BOOST technology has been developed, a very strict control of the supercapacitor charge to optimize the energy stored between each cycle, with very high levels of safety and reliability.
