Top 10 battery management system (BMS) companies in China
BMS mainly detects, evaluates, protects and balances the batteries in the energy storage system, monitors the accumulated power of the batteries through various data, and protects the safety of the batteries.
The following are top 10 BMS battery management system companies.
CATL focuses on the R&D, production and sales of new energy vehicle power battery systems and energy storage systems, and is committed to providing first-class solutions for global new energy applications. The core technologies include materials, batteries, and batteries in the field of power and energy storage batteries.
CATL’s BMS is also integrated in the battery pack. With the sales of battery modules and the application of projects in the field of new energy vehicles and the energy storage market, it is generally not provided separately to integrators in the field of energy storage or new energy vehicle companies.
BYD has set up a BMS factory research department internally, specializing in batteries, BMS and related insurance, capacitors, photovoltaics, energy storage and other businesses. BYD’s electric vehicle is equipped with its own battery and battery management system. Its battery management system not only has basic battery energy management and battery thermal management functions, but also has the function of automatic balancing of battery cells.
However, due to the difference between the BMS on electric vehicles and the BMS of the energy storage system, the battery management strategy of BYD’s energy storage products is also different. At present, there is no public information to analyze the performance or technical indicators of the BMS of its energy storage system.
Pylontech, is a dedicated BESS (battery energy storage system) provider, by consolidating the expertise in electrochemistry power electronics and system integration. It has been providing reliable and affordable ESS battery products and solutions to the global market and significantly contributing to a 7-year increasing rate by double, enabling its market position as one of the top suppliers of lithium battery storage world widely.
Founded in 2009, Pylontech has been deeply involved in the energy storage industry since its establishment. It has the design, development, and production capabilities from batteries to modules to BMS.
4. Joyson Electronics
Joyson Electronics was established in 2004 and is headquartered in Ningbo, China. It was listed on the Shanghai Stock Exchange in December 2011 and acquired Preh in Germany in the same year.
Preh, a subsidiary of Joyson Electronics, provided the battery management system for the BMW i3 pure electric vehicle, becoming the first auto parts company in China to provide the battery management system to BMW. In addition to being applied to new energy vehicles, Joyson Electronics also provides BMS systems to the energy storage field.
5. E-POWER Electronics
Huizhou E-POWER Electronics CO.,LTD was founded in 2006, advocating green , energy –saving and environmental protection as the future development concept. With R&D, sales, manufacturing and services as a set, E-POWER is a professional supplier of battery management system and battery system assembly, leading and with high market share in domestic.
The company’s automotive BMS products include EV01, EV02, EV03, EV04, and EVO5 series, and also provide large-scale BMS products to energy storage system integrators.
6. Hangzhou Xieneng
Established in May 2012, Hangzhou Xieneng is engaged in the R&D and production of new energy battery management technology, and provides professional overall battery management solutions.
The company currently has multiple models of BMS products in the five major fields of energy storage, electric vehicles, backup power supplies, two-wheel vehicles, and cascade utilization. At the end of 2019, it launched the industry’s first 1500V energy storage BS product, which supports 150QV total voltage sampling and insulation testing. Currently this product has been put into commercial use in large quantities.
7. Hangzhou kgooer electronic technology
Hangzhou kgooer electronic technology Co., Ltd. is one of the few national high-tech enterprises in China that only focuses on energy storage BMS research. The founder of Kgooer Electronic has rich practical experience and innovation ability in various battery acquisition technologies, bidirectional DC/DC active equalization technology, SOX technology especially SOC and SOH technology, IEC61850 technology, EMC/EMI technology, etc.
In 2019, the product system of Kgooer has been able to realize the remote upgrade function, and as early as 2018, it completed a number of 1500v high-voltage energy storage system export BMS supporting; And cooperated with many manufacturers to obtain UL and TUV certification and certificates for high-voltage systems from TUV and lntertek, and completed three high-voltage 10KV direct-mounted systems BMS supporting. In the past five years, the cumulative shipment of energy storage BMS has exceeded 2.6Gwh.
8. Gold Electronics
Founded in 1998, Hangzhou Gold Electronics Equipment Co., Ltd. is committed to the research and service of application characteristics and capacity analysis of regulated lead-acid batteries (VRLA), lead-carbon batteries, and lithium iron phosphate batteries. It provides many advanced, reliable and systematic solutions and product services for users in industries such as electric power, communications, electric vehicles, and energy storage.
With the continuous decline of energy storage costs, based on the mature technology of photovoltaic inverters, 1500V energy storage systems will become the mainstream of the industry in the future, and BMS will also have to adapt to DC 1500V systems, but 1500V DC systems are different from DC 900V systems. Insulation withstand voltage, data communication and processing need to be redesigned and planned.
In 2019, Gold Electronics began to develop an active balanced BMS system based on a DC 1500V system, and began to commercialize it in May 2020, with excellent performance indicators. It is the first company in the industry to launch a DC 1500V active balanced BMS system.
9. NR Jibao
Founded in 1999, NR Jibao is mainly engaged in the research and development and industrialization of power protection and control of power grids, power plants and various industrial and mining enterprises, as well as intelligent power equipment. NARI has a complete set of energy storage core equipment independently developed such as energy management system (EMS), energy storage coordination control system (PMS), energy storage conversion system (PCS) and battery management system (BMS).
Its energy storage system has been widely used on the grid side, new energy side, user side, and microgrid side.
