<div class="section abstract"> <div class="htmlview paragraph">This paper presents an intelligent continuous active Battery Management System (BMS) implementation in sodium-ion battery (SIB) energy storage systems (ESS). The 50kWh/100kWh SIB-ESS demonstration project by HiNa Battery Technology Co., Ltd. (HiNa), demonstrates better discharge voltage differential consistency 102mV (vs. 240mV without continuous active BMS) and achieving 97.6% capacity retention after 1,500 cycles. The a
