Active balancing involves the utilization of actively controlled switches or amplifying systems. [3, 8] Passive balancing utilizes shunts or self-regulating resistors to lower the effect of overvoltage. Compared to passive balancing, active balancing may be fast, in some cases energy efficient but also relatively cost intensive

The voltage measurements were performed with a self-developed measurement setup, based on the integrated circuit CY8CKIT-059 from PSoC. The data acquisition was utilized with an Excel-script. The measurement setup including the programming of the script were developed by Jon-Izkue Rodriguez from WE eiSos.

Balancing with the resistor is the slowest balancing strategy but yields the advantage of low power consumption, low cost, and easy circuit design. Depending on the resistors, it might be suitable for long-term standalone applications. The balancing speed of the Zener diode is moderate. It yields the advantage of relatively low power consumption, low cost, and easy circuit design. The relatively low power dissipation makes it suitable for long term standalone applications.

If the application's power supply breaks down, this is not a pleasant situation. Würth Elektronik eiSos built up a demonstration showing a hot-swappable backup solution with a size of 10 cm x 18.5 cm (3.94 inch x 7.3 inches). The input voltage is 24V, and the backup output voltage is 12 V for a normal industrial power rail application. The available output power is 30 W (12 V @ 2.5 A). We also talk about the classification of Supercapacitors, the model parameters and performance, and the charge-, discharge, and frequency behavior.

Electrochemical capacitors (ECs) have only recently been considered as an alternative power source for telemetry sensors of drilling equipment for geothermal or oil and gas exploration. The lifecycle analysis and modeling of ECs are underrepresented in literature in comparison to other storage devices e.g. Li-ion batteries.
