The amp-hour capacity of a battery can vary widely depending on the type and size of the battery. Smaller batteries, such as those used in small electronic devices, may have a capacity of just a few milliamp-hours (mAh), while larger batteries, such as those used in electric vehicles, can have capacities in the hundreds of amp-hours (Ah).
How Cells Form Battery Packs . The cells are arranged as modules and then interconnected to form a battery pack as shown in Figure 1. In most cases, the voltage across the interconnected series of cells is considered as a measure for detecting the SoC. Figure 1. Battery packs are formed by combining individual cells.

Batteries and similar devices accept, store, and release electricity on demand. Batteries use chemistry, in the form of chemical potential, to store energy, just like many other everyday energy sources. For example, logs and oxygen both store energy in their chemical bonds until burning converts some of that chemical energy to heat.
The battery is of type VAR, has 1.215 nominal specific gravity, and serves the station for 8 hours non-stop. The DC system has an end of discharge at 105V. This means that each cell end of discharge is at 1.75V. ... The battery capacity can be calculated using two methods, namely, the time adjustment method and the rate adjustment method.
Although most battery health studies focus on capacity loss versus age, the most accurate techniques are based on obtaining the derivative of the voltage with respect to the load (also called incremental capacity curve) and analyzing the evolution of the characteristic points of this curve [] this way, it is not only possible to predict the remaining capacity of the battery, …
Yet, even with the limited portion of the battery''s capacity that can be used for propulsion, many automakers recommend that you don''t regularly charge higher than an indicated 80 to 90 percent.
Another way to increase battery life is to recharge the battery as soon as possible after it''s been depleted. For example, if you go on a short road trip and only use 20% of the available juice in the battery when you get back home, run your electronics a bit to eat up some of the remaining power until it''s at or around 50% of capacity.
Isolation and safety: Safety features range from a "get me home" capability, which provides a limited battery capacity to the drive chain, to the complete galvanic isolation of the battery pack from all EV functions.
