Vitesco Technologies has recently achieved business contracts exceeding €2 billion with its battery management systems.
One of the key contracts for Vitesco Technologies involves a wireless communication version of the battery control unit, which is set to be integrated into 400V and 800V battery electric vehicle architectures. This innovative solution reduces the number of cables within the battery charging space, freeing up space and allowing for larger battery installations.
Battery management is a crucial function for the operation of electric vehicles. Vitesco Technologies’ intelligent BMS solution consists of control units, sensors, and software applications that prevent overheating, thereby protecting the battery. It is also designed to ensure that all cells in the battery are charged evenly, which is essential for safe driving and battery lifespan management.
Thomas Schtiarle, head of Vitesco Technologies’ electronic controls business unit, stated, “Vitesco Technologies can provide customized solutions with modular software and hardware necessary for battery management. Technology innovations like wireless communications used in battery modules enable advanced battery design, leading to cost savings for our customers.”
The BMS portfolio from Vitesco Technologies consists of two main control units. The first is the battery management controller, which permanently monitors the status of cells and modules, rectifying unfavorable operating conditions that could adversely affect range and battery lifespan. This controller detects conditions using high-voltage sensors and implements control over the high current flowing to the battery, performing the necessary functions, and in the event of an accident, the BMS executes the electrical separation of the battery from the vehicle body.
The second type of controller is the CSC (Cell Supervising Circuit), which monitors the charge levels of individual battery cells and adjusts their balance. Rodrigo Perez, responsible for Vitesco Technologies’ mass-produced batteries, commented, “Vitesco Technologies is currently developing a new technology for active cell balancing, which is expected to enhance efficiency.”
Schtiarle added, “The recent BMS-related contracts we secured indicate the vital relevance of Vitesco Technologies’ solutions in electric vehicle production. We have contracts with global automotive manufacturers, premium vehicle makers, and relevant startups, all of which are significant players in the electric vehicle market.”
Vitesco Technologies’ modular BMS portfolio already includes technology that integrates the components for other control units, and it anticipates a new trend in electric vehicles by reducing the number of devices used in electric vehicles with control units featuring high computing capability and complex software systems.
