Auto Electronics

For more than 20 years, Preh has been developing and manufacturing climate control systems, including climate control software. Preh has developed a modular solution for manual control systems permitting the automated production of 10 million control panels in more than 40 variations. Current trends, such as design for reducing the number of control elements, are being spurred on by the Advanced Development department. These also include up-to-date platform concepts for climate control systems that focus more and more on separating the control hardware from the control surface.

An independent specialist department in the development area is working on new methods for temperature sensing and climate control. As an example, algorithms for the dynamic compensation of unventilated surface sensors are developed here.

E-Mobility Power Control

As the core technology of new energy vehicles, battery management system (BMS) lays the foundation for the quality and safety of new energy vehicles. Joyson Electronics is selected by BMW GmbH as the sole supplier for BMS. BMS is consists of battery management unit (BMU) and cell supervising sensor unit (CSSU), it ensures the effective management and rational usage of power battery packs for optimal performance and prolonged lifetime. During driving, battery energy drops when discharging, rises when charging and regenerative braking. Besides, cells in the pack may exhibit different voltage levels as a result of disparities in capacities and state of health. CSSUs monitor the voltages and temperature of each cell while BMUs process the data collected by CSSUs and balance the cells to ensure the best performance of the whole battery pack.
