A Battery management system (BMS) is technology dedicated to the oversight of a battery pack. Basically an assembly of battery cells, electrically organized in a row x column matrix configuration. In Order to enable delivery of voltage and current for a duration of time against expected load scenarios. The management that the Olympus™ BMS provides includes:
- Monitoring the battery (operating temp. and capacity)
- Providing battery protection
- Estimating the battery’s operational state
- Continually optimizing battery performance
- Reporting operational status to external devices
- Automating maintenance
The term “battery” implies the entire pack; however, the battery management system monitoring and control functions are specifically applied to individual cells, or groups of cells called modules in the overall battery pack assembly. Lithium-ion rechargeable cells have the highest energy density and are the standard choice for battery packs for many consumer products, from laptops to electric vehicles. While they perform superbly, they can be rather unforgiving if operated outside a generally tight safe operating parameters. As a result many outcomes ranging from compromising the battery performance to outright dangerous consequences may arise. The BMS certainly has a challenging job description, and its overall complexity and oversight outreach may span many disciplines such as electrical, digital, control, thermal, and hydraulic.
At LV Energy Systems we implement a BMS as a management and integration tool used for automation. As a result the Luminetworx™ UL924 certified emergency lighting system is a prime example of how we use the BMS. Allowing us to perform many automated tasks all while ensuring that this critical life safety system is always operational.
