BMS ALGORITHM

EXTEND BATTERY LIFE WITH ETA-LEVELING

Traditional Balancing
Two blue bottles with a blue arrow between them.
Standard BMS systems balance cells only by voltage, which causes uneven usage of the cells over time, leading to faster aging and a noticeable reduction in capacity.
Balances cells only by voltage
Ignores capacity and impedance differences
Higher energy loss during balancing
Faster aging and earlier capacity fade
Needs closely matched and sorted cells
More maintenance windows and downtime
Often requires hardware changes for improvements
ETA-Leveling
Two blue bottles with a blue arrow between them.
Our patented ETA-Leveling algorithm considers cell capacity and impedance differences, minimizing imbalance and extending battery life without additional hardware.
Balances by effective state of charge
Considers capacity and impedance differences
Up to 52 percent less energy loss
Up to 2x longer battery lifespan
Works with unmatched and unsorted cells
Continuous readiness with minimal downtime

FAQ

Find answers to your most pressing questions about battery technology and our BMS Solutions.

What is a Battery Management System (BMS)?

A BMS is the central control unit of a battery. It monitors the state of charge, temperature, current flow, and overall cell safety. Without a functioning BMS, neither performance nor lifetime of the battery can be fully optimized. At PEM Motion, we design and develop customized BMS solutions tailored to the specific application, from early prototypes to full-scale production systems.

Why is a customized BMS better than a standard product?

Standard solutions often only cover basic functionalities and quickly reach their limits when it comes to specific requirements. A customized BMS, on the other hand, takes into account the unique characteristics of the cells, the cooling system, and the overall architecture. This makes it possible to optimize efficiency, safety, and charging speed in a targeted way. PEM Motion supports this process end-to-end, from requirements analysis to development and validation.

How can the functional safety of a BMS be ensured?

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 features and design strategies include cell voltage monitoring, temperature monitoring, and short-circuit and overcurrent protection. PEM Motion additionally leverages advanced algorithms and simulation models that ensure robust safety reserves even under extreme operating conditions, while accurately estimating State of Health (SOH) and State of Charge (SOC).

Can a BMS also be retrofitted to existing battery systems?

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.

What role does software play in a BMS?

Software is the heart of every BMS. It defines how data is processed, how decisions are made, and how protective actions are triggered, making it essential for functional safety. PEM Motion develops scalable software architectures designed for both low-volume production and high-volume industrial standards.
