Capacitor in parallel with battery for high current output
Calculate the resistance R = dV/Imax you need in the connection to the battery. This resistance limits the current from the battery to Imax when the capacitor voltage dips by dV. And ensure the battery wiring (including any fuse) has at least that resistance. If dV and thus R are too high to make this all work, increase capacitance C and try again.

6 FAQs about [Kewei characteristic capacitor connected to battery]
How much current does a capacitor draw from a battery?
In steady state (after a long time) an ideal capacitor does not draw significant current from a battery. A real capacitor will draw some small leakage current. The amount of leakage current will depend on the type of the capacitor, electrolytics will have higher leakage than films and ceramics.
Can capacitive properties of battery materials be enhanced?
A literature survey reveals that some properties of battery materials, such as the P and rate performance, can be enhanced by merging capacitive characteristics, based on the energy storage mechanisms of battery and SCs.
What is introducing capacitive behavior in battery materials?
As the name implies, introducing capacitive behavior into battery materials is the method that capacitive charge storage mechanisms are introduced into the battery materials by using different techniques, which in turn improves the performance of the battery such as P and cyclic performance, and so on.
Can a battery be connected directly to a capacitor?
However, I saw some videos and people usually do connect batteries directly with capacitors. Also, the current that flows from the battery to the capacitor is somehow of low magnitude, since it takes some considerable time to make the capacitor have the same voltage as the battery. I would like to know why this happens, thanks.
How can a capacitive contribution in battery materials balance energy and power density?
The reasonable design of capacitive contribution in battery materials can effectively balance energy and power density of devices to obtain fast-charging alkali metal ion batteries. 1. Introduction Energy, a word closely related to our life.
What is an ideal capacitor?
An "ideal capacitor" charge instantly from an ideal battery (with ideal zero-inductance wiring), in a spike of infinite current. I guess you're talking about a real battery with non-zero internal resistance, and the RC time constant for current to drop to zero.
