The battery management systems (BMS) sector is poised for impressive growth, driven by both Chinese large-scale storage needs and overseas household storage markets. The BMS market is set to expand by over 230% in 2022, a trend which is anticipated to continue. Projections indicate that the Chinese domestic lithium battery energy storage BMS market alone will reach $2.8bn by 2025.
Energy storage power stations, unlike automotive BMS, comprise thousands of individual cells connected in parallel. These systems are more intricate, having to manage deeper charge and discharge cycles and longer life spans, thus requiring BMS that can handle more complex energy management schemes.
In addition, energy storage BMS must be compatible with energy storage inverters. Through the Controller Area Network (CAN) interface, the energy storage inverter controller communicates with the BMS to access battery pack status information. This allows protective charging and discharging, ensuring safe battery operation.
The key players in the energy storage BMS market are typically third-party BMS manufacturers and energy storage battery manufacturers. These two groups complement one another, driving the development of the BMS market in tandem.
As the year 2023 heralds a boom in industrial and commercial energy storage, third-party BMS companies are investing heavily in product R&D. On the domestic front, factors such as the deepening reform of the electricity market and policy incentives like expanded peak-to-valley electricity price differentials and two-way charging and discharging schemes ensure the profitability of user-side energy storage markets.
Under the national dual-carbon policy, regions across China have begun promoting the construction of near-zero carbon emission demonstration areas, low-carbon cities, parks, and communities. In these areas, energy storage is set to become a standard feature.
Companies like Goto Electronics, Huasu Technology, and Xie Neng Technology have been actively innovating in the energy storage BMS sector. Goto Electronics, for instance, offers dedicated chips with independent intellectual property rights and products such as two-way active balance chips and 1500V active balance BMS, covering a broad range of energy storage application scenarios.
Even as more energy storage integrators begin developing their own BMS, third-party energy storage BMS manufacturers have technical barriers and experience advantages that continue to hold sway. The huge market for energy storage BMS is open for competition, encouraging innovation and cooperation for shared success.
