Battery Management: Vitesco Starts Series Production in China

Vitesco Technologies has begun series production of its battery management electronics in Changchun, China. The first large-scale series is intended for a leading Chinese automobile manufacturer.

"With the start of series production of our control electronics in Changchun, we have completed our portfolio for electrification in China. Our offering now includes highly integrated electric axle drive systems, electronic controls, intelligent sensors, battery management, and energy and thermal management systems," explains Thomas Stierle, Member of the Executive Board and Head of the Electrification Solutions Division.

Core Component of an Electric Vehicle

The battery management electronics, also known as BMC (Battery Management Controller), is a central component of the battery management system (BMS) from Vitesco Technologies. It is a core component of an electric vehicle and crucial for its safety and range. The BMC monitors the key parameters of battery cells or battery modules such as voltage, current, and temperature. Equipped with highly precise data acquisition circuits and specially developed software, it is able to efficiently process the data transmitted by the Cell Supervising Circuit (CSC) and thus monitor the battery status.

When states outside the parameter limits are detected, the electronics trigger corresponding response mechanisms, such as reducing current or activating relays, to ensure safety. In addition, it supports OTA software updates (Over-the-Air), thereby ensuring continuous optimization of system performance.
