Green energy such as solar and wind power is our future for power generation and energy utilization. As the shift to renewable sources growing, the power landscape is changing dramatically. However, how to realize reliable power delivery, where and when it’s needed, presents a bigger challenge than ever before.

Energy storage makes essential sense to meet these challenges. The global energy storage system market thrives fast from 2018 as the cost down of Li-ion battery. According to a research report(source: IHS Markit), the number of energy storage facilities around the world will grow from 5.2GW deployed in 2021 to 10.8GW by 2023. Energy storage devices stand out at the center of this energy trend.

Architecture of Battery Energy Storage Systems(BESS)

Architecture of Battery Energy Storage Systems(BESS)

Battery Energy Storage System(BESS) is structured in three main parts. The Battery System(BS) is the main carrier to store and discharge electrical energy. The Power Conversion System(PCS) is a critical component of BESS that handles the energy conversion to complete charging and discharging of the Battery System. Whereas, the Battery Management System(BMS) functions to keep monitoring the various states of the Battery System including voltage, current, temperature, cell charging state, health monitoring, etc, along with safety management of the charging and discharging processes such as the prevention of overcharge and over-discharge. This ensures BS is kept in its optimal operating state.

The BS can transfer energy and feed it into the grid through the PCS or directly supply it to users' equipment for use. Meanwhile, the grid, solar or wind energy devices can also charge the BS through the PCS to store backup power.
