What is a battery management system (BMS)?

Battery Management Systems (BMS) are at the heart of electric vehicle (EV) safety, ensuring the efficient and reliable operation of lithium-ion batteries. As batteries become more powerful and complex, maintaining their safety, performance, and longevity is critical.

What are functional safety standards in battery management systems (BMS)?

01. Functional Safety Standards (ISO 26262) Functional safety standards ensure that safety-related functionality in Battery Management Systems (BMS) is maintained throughout its lifecycle, mitigating risks that could compromise the system’s reliability and safety.

Why should you use a battery monitoring system (BMS)?

By doing all of this, the BMS helps extend battery life, improve efficiency, and ensure the safety of your EV. 1. Voltage Monitoring and Control (Lithium-Ion Battery Example) In Lithium-Ion batteries, each cell has a voltage range —usually between 2.5V to 4.2V.

Why is a battery management system important?

High-voltage batteries used in electrification applications are safety-critical & expensive components. Hence, it is vital to have an intelligent battery management system (BMS) to ensure safe and reliable operations.

Why should a BMS adhere to electrical safety standards?

Electrical safety standards are vital to ensuring that the battery system functions without causing harm to users, infrastructure, or the environment. A BMS adhering to these standards will be able to prevent unsafe conditions related to overvoltage, undervoltage, or short circuits. 03. Thermal Safety Standards

What safety protocols should be considered when designing a BMS system?

This includes fault detection, redundancy, and fail-safe mechanisms to maintain safe operation. We have outlined the important safety protocols and industry regulations that should be considered and complied while designing a robust BMS system for any industry applications involving high-voltage battery systems.
