Do you know that the device you are reading this article on, deploys a rechargeable battery? Batteries power all the portable electronic devices available in the market. The capacity may vary from a few watt hours (Wh) to a few Kilowatt-hours (kWh) based on the power requirements. For example, the power of the battery used in your mobile phone will be around 4.4 V, whereas, in an electric vehicle, it can be up to 100 kWh.
When a Lithium-ion battery is used for high-power requirements, an efficient Battery Management System (BMS) is essential. The primary function of a BMS is to protect the cells from thermal runaway and maintain SOC (State of Charge) and SOH (State of Health). Let us discuss in detail the need for Battery Management Systems and the skills needed to build a career in battery technology.
A BMS system is a complex model of hardware and software systems.
- The Hardware part includes cells, cell holders, nickel strips, PCB, PVC heat sink film, sensors and many other components. It is essential for providing support and sealing different components. Improper sealing can lead to disastrous situations like leaking and short-circuiting.
- Embedded Software makes the BMS systems actively communicate within the battery pack in sending signals. The core intelligence system monitors various parameters to maintain the SOC and SOH of the battery.
Simulink is a tool used for model-based development that is integrated into MATLAB. Using it, you can develop and test models for power electronic applications. On this platform,
It is an open-source tool used for developing customised solvers for CFD simulations. Using OpenFOAM, you can
It is a popular CFD (Computational Fluid Dynamics) tool for solving fluid dynamics problems. It provides a solution for BMS development and helps engineers in
Developed by Gamma Technologies, it provides many system-level simulation solutions for engineering across different domains, including battery technology. It helps in
A BMS engineer's roles and responsibilities include
To design an efficient Battery Management System, you must possess a basic knowledge of the different domains. Here is a list of skills that are in demand.
Today the number of electric vehicles on the road is less than 1%, but in the next decade, it is expected to increase up to 13%. As batteries are the heart of EVs and BMS is the brain, the demand for this position will continue to increase.
The average salary of a battery design engineer in India is around 6.5 Lakhs; in the US, it is around $88,400 yearly. Many top OEMs, including OLA Electric, Tesla, Mercedes Benz, Tata, Bosch and Mahindra, are hiring BMS engineers. It is the right time for you to kick-start your career as a battery design engineer.
We have discussed the software tools and skills needed for a BMS engineer. You must start gaining proficiency in those aforementioned tools and widen your knowledge base. You can choose an online course or use free study materials, but it is a long process. Also, prepare for an interview as it is the gateway to a lucrative career. You can learn some frequently asked BMS interview questions to speed up your preparation.
On this line, Skill-Lync can help you to efficiently use your time in upskilling. We offer a BMS Engineer course which will take you through the technical aspects of a battery. Also, we provide placement training with mock interviews and resume-building sessions.
It will help you to begin your career as a BMS engineer. For more guidance, feel free to talk to our experts.<link>
