Battery management systems (BMSs) are discussed in depth, as are their applications in EVs and renewable energy storage systems. This review covered topics ranging from voltage and current monitoring to the estimation of charge and discharge, protection, equalization of cells, thermal management, and actuation of stored battery data.
Battery Balancing: Battery balancing is an important function in a BMS for battery packs made up of multiple cells linked in series, which are popular in electric vehicles and energy storage systems.
It regulates and tracks factors such as voltage, current, and temperature in each cell of a battery pack to guarantee safe operation within set limits while maximizing battery life and ensuring the highest level of performance. In numerous ways, power electronics play an important role in battery management systems:
One way to figure out the battery management system's monitoring parameters like state of charge (SoC), state of health (SoH), remaining useful life (RUL), state of function (SoF), state of performance (SoP), state of energy (SoE), state of safety (SoS), and state of temperature (SoT) as shown in Fig. 11 .

By August 2025, Chile had 4.6 GWh of battery energy capacity. During 2024, 5.9 TWh of electricity was curtailed (mainly solar in the north) due to insufficient transmission, an increase from 2.7 TWh in 2023. Oasis de Atacama is a multi-site project with up to 2 GW of solar power and 11 GWh of storage.
With that, Solarpack raised its total operating capacity in Chile at the time to 181 MW. In 2013 the Atacama 1 solar complex was proposed as a 110 MW solar thermal electric plant (the first in Latin America) and a 100 MW photovoltaic plant. The solar thermal plant will include 17.5 hours of thermal storage.
Because of its good solar resource several international companies have bid record low prices for solar thermal power plants in Chile, including the Copiapó Solar Project bid at $63/MWh by SolarReserve in 2017. If realized this would have been the lowest ever price for a CSP project in the world.
Hence, timely and accurate fault detection and response by the BMS are essential to prevent such dangerous situations or battery failures. An onboard battery system typically comprises lithium-ion batteries, BMS, sensors, connectors, data acquisition sensors, thermal management systems, cloud connectivity, and so on.
The BMS calculates key battery metrics: State of Charge (SoC): The available battery capacity compared to its full capacity. State of Health (SoH): The overall health and aging status of the battery. Depth of Discharge (DoD): The percentage of battery capacity used during a discharge cycle. 05. Thermal Management
The main objective of the balancing control system, as the software section of the battery balancing system, is minimizing and removing inconsistency in the battery cells with minimum balancing time and power loss, as well as providing high and optimized performance for the battery system.
The slight difference between battery cells takes its toll on the performance of the battery pack/battery string because of the bucket effect [251, 252]. A battery balancing system is a viable solution to tackle the aforementioned problem.
