Battery Operation Method

What are the operation constraints of a battery?

These operation constraints usually contain battery voltage, current, SoC, and sometimes temperature. For the simulation applications, battery SoP reference is generally obtained by the high-fidelity battery model with the consideration of different operation constraints [ 42 ].

What is oxidation and reduction reaction in a battery?

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.

How does a battery work?

The container (battery case) is vented through vent plugs to allow the gases that form within the cells to escape. The plates in the battery are the cathodes and anodes that were discussed earlier. In figure 2-10 the negative plate group is the cathode of the individual cells and the positive plate group is the anode.

What is the basic principle of battery?

To 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.

Which data science-based methods are used in battery operation management?

To date, different data science-based methods were designed to achieve reasonable SoC estimation for battery operation management in the literature. These data science-based methods could be divided into three main categories including the direct calculation method, model-based method, and machine learning method, as shown in Fig. 4.3.

How a battery is connected?

The terminals of the individual cells are connected together by link connectors as shown in figure 2-9. The cells are connected in series in the battery and the positive terminal of one end cell becomes the positive terminal of the battery. The negative terminal of the opposite end cell becomes the negative terminal of the battery.
