Battery Management Systems (BMS)

A leading company in the electric mobility and energy storage sector required an advanced Battery Management System (BMS) to enhance operational efficiency, battery lifespan, and safety. Their business involved deploying large volumes of lithium-ion battery packs in electric two-wheelers and fleet operations, necessitating real-time monitoring and predictive maintenance capabilities.

Business Requirement

The client required a robust and intelligent Battery Management Solution to:

• Monitor State of Charge (SoC) and State of Health (SoH) in real-time.
• Optimize battery performance and prevent premature degradation.
• Reduce downtime with predictive maintenance alerts.
• Enhance safety by detecting voltage fluctuations, overheating, and short circuits.
• Integrate seamlessly with fleet management platforms and IoT systems.

Challenges Faced:

• Lack of real-time battery insights, leading to unelxpected failures.
• Frequent battery swapping, making it difficult to track performance and history.
• Operational inefficiencies due to un-optimized charging and discharging cycles.
• Security risks like battery theft and unauthorized use.

Key Features of the Battery Management Solution:
