Battery energy storage systems are essential in today's power industry, enabling electric grids to be more flexible and resilient. System reliability is crucial to maintaining these Battery Energy Storage Systems (BESS), which drives the need for precise thermal management solutions. Excess heat generated during battery operation or cold ambient conditions reduce battery life and degrade system performance.
Hotstart’s engineered liquid thermal management solutions integrate with the battery management system (BMS) of a BESS to provide active temperature management of battery cells and modules. Liquid-based heat transfer significantly increases a battery cell's temperature uniformity when compared to air-based systems heat transfer systems. In extreme ambient environments, a battery cell's energy capacity and power density decreases greatly. Ensuring the battery system will perform optimally over it's expected life cycle is critical to maintaining a cell's rated capacity without frequent failures.
Applications
Lithium-ion batteries are vulnerable to temperature extremes. Overheating can lead to thermal runaway and potential hazardous and destructive events. To mitigate the risk of catastrophic thermal runaway, it's crucial to ensure batteries are kept at a moderate, consistent, and uniform temperatures through effective thermal management.
Delivering uniformity and precise thermal management to the lithium-ion battery cells also mitigates performance degradation caused by repeated battery cycling — optimizing battery life, system performance, and reliability.
