Our main focus is in the realization of customer-specific system solutions. For SECH, it is thus an important issue to develop a product for our customers that fulfils the given requirements in the most comprehensive way. Such an ultracapacitor system can also be equipped, along with the ultracapacitor cells with active balancing and monitoring electronics and a CAN communication interface, also with power electronics for example including a DCDC converters.

Among other things, SECH offers an Energy Storage System (ESS) that can be used for temporary peak load coverage, for backup applications or for voltage and frequency stabilization in the network. The ESS consists of a single 19” ultracapacitor slot (rack) that can be built into standardised cabinets with a depth of 600 mm. Thus, even serial and parallel-switched systems in the MW range can be realized.

Compared to batteries, ultracapacitors offer several unique advantages for backup and UPS applications. On the one hand, the power is available without delay when it is needed, therefore allowing a seamless transition in the millisecond range. On the other hand, they can temporarily deliver up to 20 times more power, are relatively insensitive to low temperatures and can be completely discharged and recharged up to a million times.
