SECH ultracapacitor modules impress due to their slim, light and robust design and are characterized, as are the single cells themselves, by excellent electrical parameters. The single cells are connected to each other via aluminum bus bars, with all contacts being laser welded. The module design is scalable and flexibly conceived in order to realize energy storage with higher voltages by using series or parallel connections.

Our modules are equipped with either passive or active balancing and monitoring electronics for perfect operation of the cells, as well as a CAN communication interface. Customer-specific power and signal connections as well as communication formats are available.

Ultracapacitor modules are nowadays used in hybrid buses, rail applications, in wind power plants, for (emergency) power supply and UPS systems as well as in a variety of other industrial applications.

6V small cell modules

1.5F, 2.5F, 5F, 6V
