Refining Automotive Battery Management Systems with Lumped-Approach Thermal Modeling

Exicom optimizes BMS performance by using multiphysics simulation to understand the thermal behavior of different battery cell and pack designs.

India is a fast-growing market for electric vehicles (EVS), with one study predicting that over 30% 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. In order 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 a number of other performance parameters, such as current variation and heat generation, helping to extract optimum performance from a battery pack.

The Role of Simulation in Developing Accurate BMS

Exicom Tele-Systems Pvt. Ltd. designs, develops, and deploys energy solutions, including the latest Li-ion battery technologies. To date, it has deployed Li-ion battery solutions totaling more than 1.8 GWh - among the highest in the world by a single company. Exicom also offers charging solutions and BMS for electric two-wheelers and light electric vehicles, which are driving the growth of electric mobility in India. Exicom's innovative BMS solutions are prized for their performance and life.

At Exicom's R&D center in Gurugram, India, the technology team led by Dr. Parmender Singh has developed a BMS that can be used to precisely monitor and manage Li-ion batteries in applications across a broad voltage range (up to 1000 V). This BMS is also chemistry agnostic; it can be used with Li-ion batteries of a range of chemistries such as lithium ferrophosphate, or lithium iron phosphate (LFP), lithium nickel manganese cobalt oxide (NMC), and lithium nickel cobalt aluminum oxide (NCA).
