Industry Case Study

Battery Management Systems for Electric Vehicles


Battery management in electric vehicles and electric storage systems is a rapidly developing industry. Texas Instruments recently developed buck-boost technology that is being eyed for different applications (including mobile phones and energy grid infrastructure). NXP recently announced an expanded partnership with Panasonic and a partnership with Volkswagen. Infineon recently released an enhanced Battery Management System for electric vehicles. See below for more details.

Texas Instruments Battery Management Systems

  • BMS: Texas Instruments offers four subcategories of products in the Battery Management Systems (BMS) category: chargers, fuel gauges, monitors and balances, and protectors. It offers battery management systems ranging from less than 8 volts to more than 60 volts.
  • Partnerships: Texas Instruments has a partnership with HCL to offer solutions specifically based around medical imaging, wireless communication, and analog system applications. Texas Instruments has a long list of partners in the Internet of Things realm (including hardware and software), which can be accessed here.
  • BMS announcements/new technology: Texas Instruments announced the launch of an industry-first DC/DC buck-boost converter that extends the life of batteries by up to 50 percent in September 2020. This is expected to help with automation and grid infrastructure applications.
  • BMS announcements/new technology: In May 2020, Texas Instruments announced “the industry’s smallest buck-boost battery charger integrated circuits”, capable of providing 50 percent more energy density and three times faster charging. This will help with mobile batteries.
  • Partnerships with LG Chem, Samsung, and Panasonic: No relevant partnerships between these companies were found following a high-level search, including of Texas Instrument’s website.

NXP Battery Management Systems

  • BMS: NXP divides its BMS offerings into three categories: battery cell controllers, battery chargers, and battery sensors. It also offers a scalable battery management system for industrial and automotive applications.
  • Partnerships : NXP announced a partnership with Volkswagen in October 2020 to provide its systems in its EVs.
  • BMS announcements /new BMS technology : NXP has not made any major BMS announcements in the past six months, and has instead been focusing on topics such as enhanced Bluetooth connectivity offerings.
  • Partnerships with LG Chem, Samsung, and Panasonic: In September 2020, NXP and Panasonic announced they are expanding their partnership to provide access to NXP’s “Wi-Fi modules and microcontroller units” in Panasonic’s “electronic components, devices and modules in the automotive and industrial markets”.

Infineon Battery Management Systems

  • BMS: Infineon’s BMS offerings are divided into seven subcategories: battery monitoring and cell balancing, battery event logging, battery formation, battery protection, multi-module batteries, single-module batteries above 60 volts, and single-module batteries below 60 volts. Infineon also has Battery Management ICs for automotive, industrial, and consumer products.
  • Partnerships: Infineon has a robust network of 136 partners that can be search on this website.
  • BMS announcements /new BMS technology : In June 2020, Infineon announced a new BMS IC, the TLE9012AQU, specifically for electric cars. “It measures the voltage in up to twelve battery cells with an accuracy of ± 5.8 mV over the entire temperature and voltage range as well as the operating life cycle. Furthermore, it supports up to five external temperature sensors, provides an integrated cell balancing function and uses an iso-UART interface for communication.” The block diagram is shown below:

  • Partnerships with LG Chem, Samsung, or Panasonic: Infineon was in talks with Samsung as of 2019 to create a chip supply; however, the partnership doesn’t appear to have finalized.
  • Partnerships with LG Chem, Samsung, or Panasonic: LG and Infineon previously worked together to produce “leading edge Time-of-Flight (ToF) technology to smartphone selfie photo lovers world over” (announced in 2019).
