Vitesco lands battery management systems orders worth more than €2B

Vitesco Technologies has recently won several orders worth more than €2 billion for its Battery Management Systems (BMS). One of Vitesco Technologies’ significant contracts will deliver already a wireless communication version of the battery control units for 400V and 800V BEV architecture. This particular solution reduces the amount of cabling inside the battery, saving space and improving range capacity through the use of either a larger battery or by reducing the size and weight of the battery that would otherwise be used.

Battery management is a key function of electric driving: Intelligent BMS solutions consisting of control units, sensors, and application software protect the battery against overheating and ensure a balanced charging state of all cells. This is essential for the safe operation and long battery life. In other words, with its many individual functions the BMS protects the biggest and most valuable single system in an electric vehicle.

The core functions of BMS are divided between two types of control units in the Vitesco Technologies portfolio. The first is the battery management controller permanently monitoring the state of cells and modules. It can trigger a corrective action within the battery when an undesirable operating condition is detected in order to deliver the maximum range and achieve its maximum service life. This is accomplished through the use of a high voltage sensor to monitor and control the high current flows toward the battery. In the case of a crash, the BMS also triggers the electrical isolation of the battery from the rest of the car.
