A battery works on the oxidation and reduction reaction of an electrolyte with metals. When two dissimilar metallic substances, called electrode, are placed in a diluted electrolyte, oxidation and reduction reaction take place in the electrodes respectively depending upon the electron affinity of the metal of the electrodes. As.

AI Customer ServiceTo understand the basic principle of battery properly, first, we should have some basic concept of electrolytes and electrons affinity. Actually, when two dissimilar metals are immersed in an electrolyte, there will be a potential difference produced between these metals.
In order to accurately estimate the SOC of the battery system, we must first start from the SOC estimation of the single cell. The following describes several estimation methods of single-cell SOC and SOH. For some cases that produce bubbles in the electrode, the following method can predict the formation of bubbles while monitoring SOC and SOH.
This electrical potential difference or emf can be utilized as a source of voltage in any electronics or electrical circuit. This is a general and basic principle of battery and this is how a battery works. All batteries cells are based only on this basic principle. Let’s discuss one by one.
The minimum operating unit in a flow battery is a single cell, and a single cell can provide a voltage of about 1.26 V . A device composed of M single cells is called a stack and is generally used in small energy storage systems.
The basis for a battery operation is the exchange of electrons between two chemical reactions, an oxidation reaction and a reduction reaction. The key aspect of a battery which differentiates it from other oxidation/reduction reactions (such as rusting processes, etc) is that the oxidation and reduction reaction are physically separated.
The battery charging protocol is closely related to the daily usage of the EV and to the battery’s SOH, which will be reflected in the charging time.
