Series resonant energy storage

How a resonant tank balancing circuit works?

The resonant tank stores the excess energy from the strong cell and releases this energy to the weak cell to the battery cell string. Thus, all switches are turned ON/OFF in ZCS condition for this balancing circuit to have less power loss and take less balancing time. Fig. 1. schematic diagram proposes a cell balancing circuit. 2.2.

What is resonant energy carrier base active charge balancing algorithm?

Which resonant capacitor is used in a series resonsant circuit?

For the series resonant circuit, C and L were determined as 200 μF and 100 μH. For the experimental setup commercially available SMD capacitor, C (KTJ250B107M76BFT00), and a small parasitic resistance-formed inductor, L (SDR0403-BOURNS), were used.

What is the difference between charge balancing and resonant converter?

The charge balancing efficiency, speed, and execution are excellent; minor power loss and moderate size and cost; nevertheless, it is a complex control system. On the contrary, resonant converters have high balancing speed, low power loss, and excellent efficiency; however, it needs complex control system and is costly.

Is a composite-structure resonant switched-capacitor a voltage equalization topology?

Existing voltage equalization topologies based on the switched-capacitor (SC) operate in the hard-switch state with large energy losses and slow balancing speeds. Therefore, a voltage equalization topology derived from a composite-structure resonant switched-capacitor is proposed in this paper.

Can a nonpolar ceramic capacitor be used in a series resonant circuit?

A nonpolar ceramic capacitor would be used in this balancing circuit, and the sum of the balancing and charging current would not exceed the battery's balancing and charging current limit. For the series resonant circuit, C and L were determined as 200 μF and 100 μH.
