It’s essential to ensure a battery storage system operates at peak performance. For instance, checking the fluid levels is critical to verify the proper temperature and see if the battery is working too hard if it's liquid-cooled. Excessive heat and oxidation can lead to failure or shorten the component’s life span.
Maintenance and troubleshooting for Battery Management Systems (BMS) require a holistic approach to ensure the reliability and longevity of energy storage systems. Regular inspections and testing are foundational elements, allowing for the identification of potential issues before they escalate.
A battery energy storage system can fail for many reasons, including environmental problems, poor construction, electrical abuse, physical damage or temperature issues. A failed system could cause the battery to explode, catch fire or emit poisonous gases. Working with batteries can also lead to several hazards.
Out-of-balance cells reduce the overall usable capacity of the battery and can lead to both premature cell aging as well as overcharge or undercharge damage. An effective BMS must have precise monitoring and cell balancing capabilities to measure voltage differences and keep cells locked in at the proper levels.
Remedial measures include disconnecting the power supply, inspecting and repairing damaged parts, discharging current safely, and reinforcing preventive measures. Overcharging and over-discharging faults can lead to battery overheating, damage, increased safety risks and system faults.
When a battery is overheated, the initial cell generates flammable and toxic gasses and can reach a heat high enough to ignite those gasses. This phenomenon can cascade to adjacent cells and progress through the ESS, thus the term “runaway”. Off gassing – The gasses released from battery energy storage systems are highly flammable and toxic.
