Understanding Lithium-Ion Batteries in the EV Domain - Part 3
Electrical engineering students can get a glimpse into the popular batteries used in electronic gadgets and vehicles. The article exhibits the connection between series and parallel batteries and how they help in propulsion of the electric vehicles.
The article also discusses the importance of a drive cycle of an electric circuit and its objectives of integration within it. Finally, it concludes on the dichotomy between batteries and DC sources.
Those looking for a fulfilling career in the battery domain of electrical engineering, must learn the process of translating cells into modules and finally into usable battery packages.
An ideal battery is composed of one or more separate cells. Factors such as current, resistance, voltage, and time determine the storage capacity of these cells.
Furthermore, different cell combinations result in developing various characteristics of a particular battery. Moreover, each cell requires a feasible formula to undergo an appropriate conversion to be commercially available in the future.
In other words, the electrochemical process converts a small coin type cell into a massive 20kg heavy battery. The automotive industry necessitates this conversion in order to facilitate the smooth propulsion of its electric vehicles.
Cells can be primarily classified into two types:
1. Cylindrical Cells
2. Prismatic Cells
Usually, mobile phones use pouch type cells in their technological fabrication. Next, a battery is an advanced composed of one or multiple cells. The different parts of a cell are:
Li-ion batteries require a proper Battery Management System (BMS) for various reasons. Some of these reasons are listed below:
The conversion of a cell into a battery pack takes places through the following steps:
The drive cycle of an electric circuit denotes the pattern of propulsion of an electric vehicle. Measurements of velocity per hour determine this drive cycle in electric vehicles.
An electric vehicle requires a drive cycle for the following purposes:
To determine the level of charge left in a battery circuit, electrical engineers need to study the well-rested voltage of the cell.
For this, the voltage of a cell undergoes an accurate and a basic range modeling for its Statearge. In addition, if the battery lowers down the minimum level, it may suffer extreme damage.
Some of the parameters for a Li-ion HV battery are listed below:
This is the process of translation of a lithium-ion cell into a proper battery. Also, there exists a distinction between batteries and DC sources - batteries offer a limited capacity, while DC sources constitute an infinite capacity to propel electric vehicles.
These series of blogs would have helped you, an electrical engineering student with the applications of Li-ion batteries for electric vehicles. It sums up the different features, uses, and aspects of a typical Li-ion battery in the automotive industry.
If you are interested in entering the electrical engineering field, learning the dynamics of the different components of a lithium-ion battery is critical. Students must also know how their distinctive battery management system works to advance the optimal productivity of the vehicle.
