The study involved four major activities in estimating the current size of the automotive BMS market. Exhaustive secondary research has been done to collect information on the market, peer, and parent markets. The next step has been to validate these findings, assumptions, and sizing with industry experts across the value chain through primary research. Both top-down and bottom-up approaches have been employed to estimate the total market size. After that, market breakdown and data triangulation methods were used to estimate the market size of segments and subsegments. Two sources of information—secondary and primary—have been used to identify and collect information for an extensive technical and commercial study of the automotive battery management system (BMS) market.
Secondary Research:
Secondary sources include company websites, magazines, industry news, associations, and databases (Factiva and Bloomberg). These secondary sources include annual reports, press releases, investor presentations of companies, white papers, certified publications, articles by recognized authors, regulatory bodies, trade directories, and databases.
Primary Research
Primary sources mainly consist of several experts from the core and related industries, along with preferred automotive BMS providers, distributors, alliances, standards, and certification organizations related to various segments of this industry’s value chain.
In the primary research process, various primary sources from both supply and demand sides were interviewed to obtain qualitative and quantitative information on the market. The primary sources from the supply side included various industry experts such as Chief Experience Officers (CXOs), Vice Presidents (VPs), and Directors from business development, marketing, product development/innovation teams, and related key executives from automotive BMS providers, such as Eberspächer (Germany), Sensata Technologies, Inc. (US), AVL (Austria), LG Energy Solution (South Korea), and Ficosa Internacional SA (Spain); research organizations, distributors, industry associations, and key opinion leaders. Following is the breakdown of primary respondents.

Market Size Estimation
Both top-down and bottom-up approaches have been used to estimate and validate the total size of the automotive BMS market. These methods have also been used extensively to estimate the size of various subsegments in the market. The following research methodology has been used to estimate the market size:
-
Major players in the industry have been identified through extensive secondary research.
-
The industry’s value chain and market size (in terms of value) have been determined through primary and secondary research processes.
-
All percentage shares, splits, and breakdowns have been determined using secondary sources and verified through primary sources.
Data Triangulation
After arriving at the overall market size from the estimation process explained above, the overall market has been split into several segments and subsegments. The market breakdown and data triangulation procedures have been employed, wherever applicable, to complete the overall market engineering process and arrive at the exact statistics for all segments and subsegments. The data has been triangulated by studying various factors and trends from both the demand and supply sides. The market has also been validated using both top-down and bottom-up approaches.
Top-Down Approach
In the top-down approach, the overall market size has been used to estimate the size of the individual market segments (mentioned in market segmentation) through percentage splits from secondary and primary research. For specific market segments, the size of the most appropriate immediate parent market has been used to implement the top-down approach. The bottom-up approach has also been implemented for data obtained from secondary research to validate the market size of various segments.

Bottom-Up Approach
The bottom-up approach has been used to arrive at the overall size of the automotive BMS market from the revenues of the key players and their market shares. Calculations based on revenues of key companies identified in the market led to the estimation of their overall market size.

Market Definition
A battery management system (BMS) is an electronic device that monitors and controls the operation and functioning of a rechargeable battery. It is called the brain of the battery, as it enhances safety, performance, charging rates, and longevity by managing current, voltage, temperature, and battery capacity. Its primary functions include protection from overcharging, ensuring safe operation, cell balancing, voltage and temperature control, and determining the state of charge (SoC) and state of health (SoH) of the battery. A battery management system typically comprises hardware and software customized per applications and battery specifications.
An automotive BMS is a crucial component of electric vehicles (EVs) that accurately monitors, protects, and optimizes the performance of the EV battery. The BMS is responsible for ensuring the battery's safety, preventing it from operating outside its safe operating area. The main functions of an automotive BMS include monitoring, protection, optimization, integration, scalability, safety, and compliance.
