Automotive BMS
Please choose a subcategory
All automotive batteries require management. Such batteries vary in voltages and chemistries, thus requiring different battery management solutions (BMSs) and methods. The following table shows the different types of batteries that are widely used in cars:
| 12V Battery | 48V Battery | 400-800V BMS | |||
| All Vehicles | Electric Two & Three Wheelers | Mild hybrid electric vehicles | Full hybrid electric vehicles | Plug-in hybrid electric vehicles | Battery electric vehicles |

- The 12V battery can be found in all types of vehicles. Its function is the power hub of the low voltage power distribution, backup power and for start/stop operation in ICE cars.
- The 48V battery is mostly found in low-speed electric vehicles (such as electric two-wheelers) and mild hybrid electric vehicles (MHEV). Its function is to provide start-stop, regenerative braking, torque boost, and power to the electric drive.
- The high voltage battery is mostly found in FHEVs, PHEVs, and BEVs. The most two common high voltage batteries are 400 & 800V solutions. Its function is to provide start-stop, regenerative braking, torque boost, and power the electric drive.
In all the mentioned batteries the key function of the BMS is to manage, protect and optimize the performance of the batteries. Learn more about Infineon's full BMS offering and how it is used to maximize the performance of the batteries.
Getting the most out of batteries. By the end of this decade, the majority of new cars sold around the world is expected to have a partially or fully electric drivetrain. Battery management systems have a great impact on the range, cost and service life of electric vehicles, which makes them a key success factor for this mobility revolution. Furthermore, they play an essential role when it comes to second-life concepts that allow former EV batteries to be used as flexible storage for renewable energy, for example. Dr. Clemens Mueller exclusively explains in-depth market trends and challenges, provides details on Infineon products and solutions, and introduces the new BMS-IC TLE9012AQU.
