In the recent last decade, we have seen news reports regarding heating up of mobile phone batteries and in many cases, it has also exploded injuring the consumer. Similarly, we also have had cases of Hyundai Kona catching fire in the summer season, due to excessive heating of the cell. All these incidents have proved how important it is to monitor lithium-ion cells.

The lithium-ion chemistries provide a high energy density of about 120 – 200 Wh/kg, as compared to a 40 – 50 Wh/kg of lead-acid battery. Due to space restriction, this difference in energy density has been the major reason for gaining popularity of these cells in Electric Vehicles. Despite providing high energy density, these cells also can provide high charge and discharge rate as required, but running it at those high rates might cause an increase in temperature of the cell and create instability. This is known as thermal runaway.

In order to control this, it becomes necessary to use a Battery Thermal Management System to monitor the charge and discharge cycle as well as cell balancing. Along with this for battery packs employed in electric vehicles might also require a good thermal management system, to control the heat dissipation and keep cells within temperature limits.

In this course, we will take a look at the various BMS architecture and thermal management systems, along with simulations for thermal dissipation.
