BMS market is transitioning from independent suppliers to a more intricate ecosystem.


  • The total BMS market will increase to US$11.9 billion in 2028, with a CAGR of 15.6% between 2022 and 2028.
  • Main BMS components’ market figures: AFE will reach more than $2 billion in 2028. The microcontroller market will increase to about $1.3 billion the same year. And the various sensors required should be at $3.50 billion in 2028.
  • Supply chain: the xEV BMS market is shifting from independent BMS suppliers to a more complex ecosystem…
  • The BMS is evolving into AI-based SoX algorithm, digital twin in cloud, merging to a domain controller, incorporating new functionalities.

Globally, the growth of vehicle electrification is accelerating across major markets. By 2028, the global light vehicle market is projected to reach 93 million units, with xEVs commanding a significant 53.5% market share. Among various electrification technologies, BEVs take the lead in market growth, exhibiting a CAGR of 22.1% from 2022 to 2028, while the overall xEV annual growth during the same period stands at 16.7%.

Thematic(s) :

Analysts closely examined the global market trends and provided forecasts of BMS and critical components. They also offer a comprehensive picture of the BMS supply chain, including OEMs, BMS suppliers, and key component suppliers. On the technology side, this report provides a detailed analysis of the state-of-the-art BMS technologies, having investigated the many emerging technologies, such as BMS integration to other sub-systems, active balancing, wireless BMS, cloud BMS, and integrated EIS .

In this dynamic context, the market landscape is evolving. The xEV BMS market is undergoing a shift from independent BMS suppliers to a more intricate ecosystem involving three major groups:

  • Independent BMS suppliers
    Early entrants with a primary focus on BMS, lacking significant upstream involvement in key component manufacturing. An exception is Sensata, which, through the acquisition of Lithium Balance, extended its reach downstream to become a BMS supplier.
  • Battery Pack/Cell suppliers
    There is a notable uptick in BMS business from battery pack suppliers who handle both battery cells and BMS internally. This integration provides comprehensive cell data to the BMS, of particular benefit to SoC algorithms. Importantly, the amalgamation of BMS with battery packs offers commercial advantages, resulting in increased market share for pack suppliers.
  • In-house OEMs
    In the transition to electrification, automotive OEMs are moving upstream by manufacturing battery packs/e-axles in-house. This trend is also observed in BMS, which is closely tied to battery packs. Tesla set the trend, and other OEMs are following suit.

Baseband virtualization (V-RAN) in the 5G standalone architecture shifts baseband and core functions to servers, streamlining cellular private network deployment,” explains Cyril Buey. “Two main private network types are standalone (isolated from public networks) and shared (integrated with MNO networks).”

In parallel, the main BMS components, such as AFEs, micro-controllers, sensors, etc., have a relatively stable supply chain.

As a pioneering region in vehicle electrification, the Chinese market is developing a robust supply chain driven by the success of the battery cell sector. Battery giants like CATL, SinoEv, and REPT play pivotal roles in both the battery and BMS domains.
