I have a battery powered device (motion sensor) CR2032 or CR2477. I have consulted the sample designs and found that there is usually a capacitor with a value from 220uF to 330uF in parallel with the battery. What is the effect of this capacitor other than ripple voltage flattening? Is it related to the RC charging and discharging circuit?
The capacitor should have the closest and most direct connection to the load, then this pair should be connected to the battery via wiring which gives you some control of the current drawn from the battery. Find the maximum recommended current (Imax) from the battery, probably from its datasheet.

The Parallel Combination of Capacitors. A parallel combination of three capacitors, with one plate of each capacitor connected to one side of the circuit and the other plate connected to the other side, is illustrated in Figure (PageIndex{2a}).

In practice, two or more capacitors are sometimes connected together. The circuit diagrams below illustrate two basic combinations: parallel capacitors and series capacitors. The equivalent capacitance is the capacitance of the single capacitor that can replace a set of connected capacitors without changing the operation of the circuit
The parallel hybridization of electrochemical capacitors with batteries at the internal level in an "internal parallel hybrid" (IPH) consists in the realization of a device where both electrodes contain electrochemical capacitor and battery materials.

4 bank parallel minus 2 capacitor. My batteries top voltage is 56.8 v so I needed at least 21 capacitor for that voltage. But because the balance circuit is good for two, I''ve put 22.

Putting a large supercap in parallel with the battery does not change the terminal characteristics. You still would have low voltage trips at 10.5V, and still classify as fully charged at 13.4V. The charge stored in a capacitor is: W = 1/2 * C * V^2. For a capacitor in parallel with a 12V battery the total charge in the capacitor would be:

This relationship shows us that when we connect capacitors in parallel then the equivalent capacitance of the circuit becomes sum of the capacitances of each individual capacitor in the connection. in other words, the total capacitance of the circuit increases.
Klementov showed that a capacitor parallel combined with batteries can provide the peak current needed to crank a heavy duty vehicle engine . The optimal capacitor will have a minimum difference between stored and delivered energy, thus batteries are important for multiple starts.

As for any capacitor, the capacitance of the combination is related to the charge and voltage by using Equation 8.1. When this series combination is connected to a battery with voltage V, each of the capacitors acquires an identical charge Q.

Figure 8.11 illustrates a series combination of three capacitors, arranged in a row within the circuit. As for any capacitor, the capacitance of the combination is related to the charge and voltage by using Equation 8.1.
The capacitor temporarily accepts the charge which is then partially transferred to the battery equilibrating the system. The current sharing and the equilibration of the two devices was observed experimentally or predicted in many cases. The effect of the reduced voltage drop is an increased run time of the battery.
