BATTERY MANAGEMENT SYSTEM-TRACKING EV BATTERY PACK HEALTH

THE FUNCTIONS OF AN ELECTRIC VEHICLE RELY HEAVILY ON ITS BATTERIES, MAKING THEM A CRUCIAL COMPONENT THAT REQUIRES CONTINUOUS MONITORING AND CONTROL. TO ACHIEVE THIS, AN EV BATTERY MANAGEMENT SYSTEM (BMS) IS ESSENTIAL.

ELECTRIC VEHICLES (EVS) ARE GAINING popularity due to their environmental friendliness, energy efficiency, and lower operating costs. However, EVs come with unique challenges, one of which is the management of their batteries. Different types of batteries are used to power electric vehicles, and deciding which battery is best depends on its energy storage efficiency, production costs, constructive characteristics, safety, and lifespan.

“It is true that EVs have been gaining popularity in recent years as charging infrastructure improves and battery technology becomes more efficient. According to IEA, the figure of electric cars on the road could reach 145 million by 2030. Furthermore, main automakers have been investing a lot in EV machinery and introducing the latest electric models to their lineups. Overall, the transition to EV is well in progress, and it seems likely to continue as more with the environmental and economic benefits of electric vehicles, shares Dr Abhishek Choubey, Head- Industry Institute Partnership Cell (IIPC) & Associate Professor, Department of Mechanical Engineering, Sagar Institute of Science Technology & Research (SISTec), Bhopal.

Lithium-ion batteries are the most utilised technology in electric cars. EVs run on high voltage lithium-Ion battery packs. Lithium-ion batteries have higher energy density (100-265wh/kg) compared to other battery chemistries. They pose a risk of fire under unusual circumstances. It is crucial to operate electric vehicles in pre-defined safety limits to ensure the safety of the user as well as the vehicle.
