Rietheim-Weilheim, Germany- Marquardt Group has introduced a new battery management technique. Batteries serve as the heart of every electric vehicle, and with its battery management systems, Marquardt ensures their reliable operation over an extended period. The company's latest innovation, the cell module controller (CMC), was showcased at the Battery Show in Stuttgart, marking a significant advancement in battery management systems for electric vehicles. The CMC monitors individual battery cells in real-time, enabling optimized performance and protection against failure. This innovation extends beyond mobile applications, potentially finding use in stationary energy systems as well.
The Cell Module Controller by Marquardt addresses critical parameters like deep discharge, overcharging, and temperature peaks in lithium-ion batteries to uphold safety standards. By monitoring individual cells, it gathers crucial data on battery condition and performance. In case of issues, the CMC communicates with the master control unit, which takes appropriate actions such as charging, cooling, or rebalancing.
The CMC ensures balance among the hundreds of cells comprising a battery pack by preventing scenarios like incomplete charging, which can lead to voltage imbalances. Real-time monitoring and control mitigate these risks, optimizing battery operation and safeguarding against overcharging and overheating. By enhancing safety and longevity, the CMC minimizes the likelihood of battery failure and the costly need for replacements in the long term, this result is considerable savings potential.
Marquardt's cell module controller offers compatibility with a diverse array of battery chemistries and form factors. Its analog front ends (AFE) function independently of software, acting as a communication bridge to other electronic control units within the system. This design ensures the CMC's versatility and seamless integration into various setups.
The Cell Module Controller provides maximum flexibility for automotive, truck, and cell manufacturers, and can also be integrated into stationary battery systems. Its scalable design is regularly updated to meet industry standards and customer needs. Marquardt is currently developing wireless variants of the CMC to enhance adaptability, installation efficiency, and usability across various applications.
Marquardt is set to unveil more details at the Battery Show in Stuttgart from June 18 to 20.
