在固定能量存储中使用二次使用EV电池的显著成本是功率转换和处理。通过降低成本，可以实现电动汽车电池和电池储能系统（BESS）的可持续循环经济潜力。二次使用电池的挑战在于其特性的异质性，这使得用于功率处理的主流方法特别密集，因此昂贵。我们提出了一种稀疏分层部分功率处理（LS-HiPPP）策略，该策略克服了并联电池的这些障碍，这些障碍在较低电压的应用中是需要的，包括EV快速充电的能量缓冲和表后能量存储。
A significant cost in using second-use EV batteries in stationary energy storage is power conversion and processing. By reducing this cost, the potential for a sustainable circular economy for EV batteries and battery energy storage systems (BESS) can be realized. The challenge with second-use batteries is the heterogeneity of their characteristics, which makes prevailing methods for power processing particularly intensive, and hence expensive. We present a lite-sparse hierarchical partial power processing (LS-HiPPP) strategy that overcomes these obstacles for batteries in parallel, which are needed in lower voltage applications that include energy buffering for EV fast charging and behind-the-meter energy storage.
