Abstract Lithium-ion batteries have recently been in the spotlight as the main energy source for the energy storage devices used in the renewable energy industry. The main issues in the use of lithium-ion batteries are satisfaction with the design life and safe operation. Therefore, battery management has been required in practice. In accordance with this demand, battery state indicators such as the state-of-charge (SOC), state-of-health (SOH), state-of-function (SOF), and state-of-temperature (SOT) have been widely applied. The use of these indicators ensures safe operation without overcharging and over-discharging. In addition, it can also help satisfy the design life. This paper presents a literature review of battery state indicators over the last three years and proposes the requirement of state-of-the-art battery state indicators. It also suggests future developments for battery management system (BMS) in stationary energy storage systems (ESSs).

1 Introduction Recently, CO2 emission have been limited to constrain global warming under the Paris Climate Agreement of 2015. Therefore, the use of internal combustion engines has been decreasing, and the use of eco-friendly energy sources, especially batteries, has been rapidly increasing as a replacement [1]. Among eco-friendly energy sources, lithium-ion batteries have been widely used in the energy industry as a replacement for lead-acid batteries and Ni-MH batteries since they offer the advantages of high energy and power densities, long life expectancy, and low self-discharge rate. Thus, lithium-ion batteries have been adopted in many energy storage systems (ESSs) [2, 3]. However, lithium-ion batteries have an economic disadvantage owing to their need * Jonghoon Kim [email protected] 1

for expensive raw materials such as cobalt, which means these batteries make up a significant portion of the price of applications, as shown in Fig. 1a [4, 5]. Battery-based ESSs can be divided into stationary ESSs and mobile ESSs as shown in Fig. 1b. Stationary ESSs include photovoltaic/ wind power generation connected ESSs, uninterruptible power supplies (UPSs), and emergency power supplies (EPSs). Meanwhile, mobile ESSs includ
