Refining Automotive Battery Management Systems with Lumped-Approach Thermal Modeling

India is a fast-growing market for electric vehicles (EVs), with one study predicting that over 30 percent of the vehicles sold in India will be electric by 2030. The battery packs that power EVs are one of the main drivers of the electric mobility revolution in India. To monitor and manage battery pack performance and safety, packs are usually equipped with a battery management system (BMS). A BMS is an electronic system that monitors a battery’s voltage, temperature, coolant flow, and health and predicts several other performance parameters, such as current variation and heat generation, helping to extract optimum performance from a battery pack.
