They help balance the supply and demand on the grid, improve energy utilization efficiency, and reduce dependence on traditional energy sources. A complete electrochemical energy storage system primarily consists of battery packs, BMS, EMS, PCS, and other electrical equipment.
In an energy storage system, the battery pack sends status information to the BMS. The BMS shares this information with the EMS and PCS. Based on optimization and scheduling decisions, the EMS sends control information to the PCS and BMS, directing the charging and discharging processes of individual batteries or battery packs.
By integrating advanced BMS, EMS, and PCS technologies, Bonnen ensures the optimal performance, reliability, and safety of energy storage systems, helping to lead the way in sustainable and efficient energy management.
What is PCS?
PCS (Power Conversion System) of energy storage system.
PCS can work in the following two states and therefore has two important functions:
1. Rectifier working state: convert the AC power of the grid into DC power when charging the battery cell of the energy storage system.
2. Inverter working state: convert the DC power of the battery cell into AC power and feed it into the grid when discharging the battery cell of the energy storage system;
Therefore, PCS is an important device for realizing bidirectional energy transfer between DC battery cells and AC grid.
In recent years, due to the development and performance improvement of new power electronic devices including IGBT (insulated gate bipolar transistor) and IGCT (integrated gate commutated thyristor), the production and application of high voltage and high power PCS devices have become a reality.
Specifically, Battery Management System BMS: plays a sensing role, mainly responsible for battery monitoring, evaluation, protection and balancing;
Energy Management System EMS: plays a decision-making role, mainly responsible for data collection, network monitoring and energy scheduling;
Energy Storage Converter PCS: plays an execution role, the main function is to control the charging and discharging process of the energy storage battery pack and perform AC/DC conversion.
What is BMS?
BMS (Battery Management System), commonly known as the battery nanny or battery steward, is a device that cooperates to monitor the status of energy storage batteries. BMS and battery cells together form a battery system.
BMS Function
BMS plays a sensing role in the energy storage system. Its main function is to monitor the operating status of each battery in the battery energy storage unit and ensure the safe operation of the energy storage unit.
BMS measures the basic parameters of the battery, including voltage, current, temperature, etc., to prevent overcharging and over discharging of the battery and extend the battery life.
BMS needs to calculate and analyze the battery's SOC (remaining battery capacity) and SOH (battery health status), and report abnormal information in a timely manner.
BMS Layered perception architecture
Most BMS systems are three-layer architectures, and the hardware is mainly divided into slave control unit, master control unit and master control unit.
1. Bottom layer: slave control BMU, which is the single cell management layer. It is composed of battery monitoring chip and its auxiliary circuits, responsible for collecting various types of information of single cells, calculating and analyzing the battery's SOC (remaining battery capacity) and SOH (battery health status), realizing active balancing of single cells, and uploading single cell abnormal information to the master control.
2. Middle layer: master control BCU, which is the battery pack management layer. Collect various single cell information uploaded by BMU and collect battery pack information. Calculate and analyze the SOC and SOH of the battery pack.
3. Upper layer: master control, which is the battery cluster management layer. Responsible for the overall coordination within the system and external information interaction with EMS and PCS, and control the operation process of the entire BMS system according to external requests.
Energy storage BMS development trend
Currently, BMS functions have evolved from basic functions such as monitoring, communication, protection, display, and storage to advanced functions such as battery system safety diagnosis and long-life operation and maintenance, and system economic index diagnosis.
From a technical point of view, active balancing technology will become the standard, and technologies such as big data and artificial intelligence will be applied to battery status algorithms; in the future, the survival space of low-end BMS suppliers will become smaller and smaller.
Intelligent operation and maintenance, advanced functions, etc. are the core points for differentiated competition among manufacturers in the future.
Deeply integrate big data management and cloud-edge collaboration.
Develop cloud-edge collaboration based on BMS, give full play to the data aggregation capabilities of BMS, realize the collection, analysis, status diagnosis and evaluation of real-time data of battery systems at the station-level equipment end, and realize data cleaning and pre-processing;
Based on more station-side data, the cloud can realize multi-dimensional spatiotemporal data mining, refining, and fine processing, realize more detailed and comprehensive evaluation of battery operation status, safety status, and energy storage system reliability, dynamically optimize BMS operation strategies and algorithm models and set them down to the equipment end, achieve the best safety and economic operation and maintenance mode, realize intelligent operation and maintenance, and provide data support for energy aggregation/distribution/trading, and provide guarantee for the value realization of energy storage systems.
What is EMS?
EMS (Energy Management System) is the decision-making center of the energy storage system and plays the role of "brain". Energy management systems include grid-level energy management systems and microgrid-level energy management systems. The EMS mentioned in energy storage systems generally refers to the microgrid level.
Composition
Energy management systems are generally divided into equipment layer, communication layer and application layer.
Equipment layer: requires energy acquisition and conversion (PCS, BMS) as support;
Communication layer: mainly includes links, protocols, transmission, etc.;
Information layer: mainly includes cache middleware, database, and server, among which the database system is responsible for data processing and data storage, records real-time data and important historical data, and provides historical information query;

High Voltage vs. Low Voltage: Which is the Ideal Choice for Home Energy Storage?
In the realm of Solar PV systems, both high voltage and low voltage lithium battery systems reign supreme. But when it comes to your specific needs, which one holds the edge? This article delves into the comparison between High Voltage (HV) and Low Voltage (LV) lithium battery systems, empowering you to make an informed decision.
Understanding Low Voltage Battery Systems
Low voltage home battery backups typically operate below the 100V threshold. Their reduced voltage output translates to lesser power compared to their high voltage counterparts.
Advantages of Low Voltage Battery Systems
Low voltage home battery backups boast several advantages. They are notably easier to install and upgrade, allowing for parallel or series connection of multiple batteries. Moreover, their smaller physical footprint makes them ideal for space-constrained applications. Additionally, low voltage batteries are more cost-effective to manufacture than high voltage alternatives. Safety-wise, they hold certain advantages, albeit they may face challenges with start-up loads, which can be mitigated by temporarily linking the system to the grid or solar energy sources – albeit at the cost of time.
Application of Low Voltage Solar Batteries
Low voltage solar batteries find prominence in off-grid systems catering to medium to low energy demands. However, the choice of inverters plays a pivotal role. Each inverter is calibrated for a specific battery voltage range, dictating compatibility with high or low voltage batteries. Most battery inverters, rated at 48V or higher, can accommodate both types. Thus, selecting an inverter for low-voltage home energy storage necessitates consideration of its voltage range, ensuring alignment with the battery's nominal voltage.
Exploring High Voltage Battery Systems
High voltage battery systems typically exceed the 100V mark. Their heightened power enables faster charging and discharging, making them adept at addressing sudden demand spikes from equipment startups. Moreover, the increased voltage results in smaller conductors.
Advantages of High Voltage Battery Systems
High voltage battery systems represent a relatively recent advancement in home solar battery backups. Their elevated voltage levels facilitate greater energy output, ideal for homes with higher electricity consumption rates. Opting for a high-voltage battery not only enhances efficiency but also conserves energy. With a DC bus voltage ranging between 300 and 500V, inverters face reduced workload, translating to enhanced energy efficiency for residential and commercial power needs. Furthermore, high voltage battery systems tout longer lifespan, higher discharge rates, and enhanced safety features, making them an increasingly favored choice.
Cost Considerations
While high-voltage batteries generally command a higher market price than their low-voltage counterparts due to manufacturing costs and brand premiums, several factors influence lithium battery prices, including type, size, quality, and supplier. Thus, buyers are advised to conduct thorough price comparisons across different suppliers before finalizing a purchase.
Selecting the Optimal Home Solar Battery Backup
