The 3 "S"s of Industrial and Commercial Energy Storage System

Industrial and commercial energy storage systems consist of BMS, EMS, PCS, etc. Among them, BMS manages battery safety, EMS is responsible for energy scheduling, and PCS realizes the bidirectional flow of electric energy. Reasonable configuration and optimization of the collaboration among the three can ensure the safe, stable, and efficient operation of the energy storage system.

EMS Stands for Energy Manager System

As the core of the industrial and commercial energy storage system, EMS is responsible for data collection, data analysis, and energy scheduling to ensure the balance and normal operation of the energy of the industrial and commercial energy storage system. EMS can monitor the status of energy storage system equipment in real-time and achieve optimal energy allocation and scheduling through economic operation strategies and safety protection strategies.

PCS Stands for Power Conversion System

Mainly responsible for managing current conversion, it can be a bidirectional current inverter, managing both input and output ends. It can control the charging and discharging process of the battery, perform AC/DC conversion, and directly supply power to AC loads in the absence of a power grid. PCS consists of a DC/AC bidirectional inverter, control unit, etc. PCS plays a key role in industrial and commercial energy storage systems, ensuring bidirectional current flow and adapting to different charging and discharging requirements.

BMS Stands for Battery Manager System

Responsible for monitoring the charging and discharging statuses of the battery, including real-time monitoring of basic parameters such as voltage, current, and temperature, as well as the control of battery charging and discharging, ensuring that the battery operates within a suitable temperature range and preventing damage from overcharging, over-discharge, or overload. It is mainly used for monitoring, calculation, communication, and protection of battery packs. It mainly consists of battery management chips, analog front ends, embedded microprocessors, and embedded software, among others. BMS can also balance the charge differences between individual cells within a battery pack, improving the overall capacity and lifespan of the industrial and commercial energy storage system.

By monitoring, controlling, balancing, and protecting the battery, the performance, safety, and lifespan of the industrial and commercial energy storage systems can be further improved, thereby ensuring the long-term safe operation of the system.

As the core components of industrial and commercial energy storage systems, EMS, BMS, and PCS are crucial to the performance and effectiveness of the entire industrial and commercial energy storage system. Reasonable configuration and optimization of their collaborative work can help achieve the best performance and sustainability of industrial and commercial energy storage systems.
