BESS Auxiliary Power
Most BESS products on the market require an external power supply circuit for their auxiliary loads, although some have built-in circuits and do not
By doing so, it ensures that energy resources are utilized more efficiently, minimizing waste and improving the overall efficiency of energy production and distribution. The BESS also offers significant operational flexibility, allowing it to adapt to varying energy demands and supply conditions quickly and effectively.
For certain projects, backup power must be provided for the BESS auxiliary load as required by the BESS supplier or fire codes. Some BESS suppliers mandate uninterrupted power to maintain the operation of thermal management systems, ensuring battery temperatures remain within desired limits to minimize degradation.
As discussed above, auxiliary power is a vital consideration in BESS project design and development. While it is an important aspect, a comprehensive approach, such as the total cost of ownership method, should be used for BESS product evaluation and selection.
If a BESS product cannot meet these backup power requirements as mandated by the code or the Authority Having Jurisdiction (AHJ), an external backup power source needs to be provided. Options for backup power include local distribution network feeders (if available with sufficient kVA rating) or backup generators.
