CUSTOM BMS DEVELOPMENT

A Battery Management System (BMS) integrates multiple safety mechanisms to ensure safe battery operation.

It continuously monitors cell voltages and automatically disconnects the system if overvoltage or undervoltage conditions are detected. Protection against overcurrent and short circuits is also implemented. In addition, the BMS tracks cell temperatures in real time to prevent overheating.

These protection functions safeguard the battery from damage, reduce failure risks, and significantly improve overall system safety.

For complex applications, these protection logics are often tailored to the specific system architecture and use case to maximize both safety and performance. PEM Motion supports here with the development of a custom-specific BMS.

Standard solutions often only cover basic functionalities and quickly reach their limits when it comes to specific requirements. A custom-designed BMS offers significant advantages compared to standard solutions:
• Optimized safety logic for the specific application
• Improved state estimation accuracy (SoC/SoH)
• Better thermal and performance management
• Higher system efficiency and longer lifetime
• Seamless integration into the overall system architectur

Custom BMS development, such as the solutions provided by PEM Motion, enables companies to fully unlock the performance potential of their battery systems instead of adapting the product to a generic control system.

Ensuring functional safety for a Battery Management System (BMS) primarily involves adhering to specific international standards, especially ISO 26262 for automotive applications and IEC 61508 for industrial applications. These standards provide a systematic framework for managing and mitigating risks throughout the product development lifecycle.

Key safety software features and design strategies include cell voltage monitoring, temperature monitoring, and short-circuit and overcurrent protection. It defines how data is processed, how decisions are made, and how protective actions are triggered, making it essential for functional safety. PEM Motion provides modular software architectures tailored to customer requirements. These architectures also use advanced algorithms and simulation models to maintain strong safety measures, even in tough conditions, while accurately assessing the State of Health (SOH) and State of Charge (SOC).

Yes, retrofitting is possible – especially when batteries are reused in second-life applications. PEM Motion offers retrofit solutions and the integration of modern BMS architectures to make existing systems safer and more efficient.

For basic applications, particularly those with standardized requirements and limited performance demands, off-the-shelf BMS solutions can be used.

However, they often lack flexibility in terms of system integration, safety strategy, and application-specific optimization. This can result in reduced performance or limitations in scaling and certification.

For advanced industry applications, PEM Motion typically recommends and develops custom BMS that fit the specific system design, regulatory requirements, and performance targets, ensuring they can grow over time and stay competitive. We support tailored BMS development and design HV BMS that fully meet the specific requirements and needs for every industry application, from drones to commercial vehicles and stationary energy storage.Off-the-shelf BMS solutions can be used for basic applications, especially where requirements are standardized and performance demands are limited.
