As an electronic component of real-time monitoring, automatic balancing, and intelligent charging and discharging, the battery management system plays an important role in ensuring safety, prolonging life, estimating the remaining power, etc., and is an indispensable component in the power and energy storage battery pack. The energy storage battery management system is very similar to the power battery management system. The power battery system is in a high-speed moving electric vehicle, and there are higher requirements for the power response speed and power characteristics of the battery, the accuracy of SOC estimation, and the number of state parameter calculations. The scale of the energy storage system is very large, and the centralized battery management system is significantly different from the energy storage battery management system.   1. The position of the battery and its management system in their respective systems is different.   In the energy storage system, the energy storage battery only interacts with the energy storage converter at high voltage, and the converter takes power from the AC grid to charge the battery pack; Or the battery pack supplies power to the converter, and the electrical energy is converted into AC and sent to the AC grid through the converter. The communication of the energy storage system and the battery management system mainly have an information interaction relationship with the converter and the energy storage power station dispatching system. On the one hand, the battery management system sends important status information to the converter to determine the high-voltage power interaction. On the other hand, the battery management system sends the most comprehensive monitoring information to the PCS, the dispatching system of the energy storage power station.   2. The hardware logic structure is different The hardware of the energy storage management system generally adopts a two-layer or three-layer mode, and the larger scale tends to be a three-layer management system. The power battery management system has only one layer of centralized or two distributed, and there will be no three-layer situation. From the functional point of view, the first and second layer modules of the energy storage battery management system are basically equivalent to the first layer acquisition module and the second layer main control module of the power battery. The third layer of the energy storage battery management system is an additional layer on top of this to cope with the huge scale of energy storage batteries.   3. There is a difference in communication protocol: The energy storage battery management system and the internal communication basically use the CAN protocol, but its communication with the external mainly refers to the energy storage power station dispatching system PCS, which often adopts the Internet protocol format TCP/IP protocol. The power battery is located in the general environment of electric vehicles using the CAN protocol, but according to the internal components of the battery pack using internal CAN, and the battery pack and the vehicle using vehicle CAN to distinguish.   4. The types of battery cells used in energy storage power stations are different, and the management system parameters are quite different. The current mainstream battery types for electric vehicles are lithium iron phosphate batteries and ternary lithium batteries. The external characteristics of different battery types vary greatly, and battery models cannot be used universally. The battery management system and the cell parameters must be one-to-one correspondence. The detailed parameter settings of the same type of battery cell produced by different manufacturers will not be the same.   5. The passive equilibrium conditions for the application of energy storage battery management system are relatively good, and the requirements of energy storage power stations for the balancing ability of the management system are very urgent. The scale of the energy storage battery module is relatively large, and the large single battery voltage difference will cause the capacity of the whole box to decrease, and the more batteries in series, the more capacity it will lose. From the perspective of economic efficiency, energy storage power stations need to be fully balanced. And because of the abundant space and good heat dissipation conditions, passive balancing can play a better role, using a relatively large equalization current, and there is no need to worry about the problem of excessive temperature rise. Low-cost passive equilibrium can be used in energy storage power stations.

The high voltage Battery Management System (BMS) plays a crucial role in ensuring the safe, efficient, and reliable functioning of high voltage lithium-ion battery packs, which operate at over 96 VDC. As the demand for power storage continues to grow, the significance of high voltage BMS becomes increasingly evident. In this article, we will provide a thorough overview of high voltage BMS, covering essential aspects related to its operation and applications.   Understanding High Voltage BMS The high voltage BMS serves as an electronic supervisory system designed to manage high voltage battery packs by monitoring and measuring cell parameters while assessing their overall state. Additionally, it safeguards battery cells by ensuring they operate within the safe operating area (SOA). These systems have become indispensable components of lithium-ion battery packs. High voltage lithium batteries consist of numerous lithium-ion cells connected in parallel and series to achieve the desired capacity and voltage for the pack. The high voltage BMS, which operates within the range of 96 VDC to 1500 VDC, manages all these batteries. Notably, high voltage BMS primarily adopts distributed BMS technology.   Composition of High Voltage BMS High voltage BMS battery systems comprise an array of cells, resulting in multiple wires connecting the battery cells to the BMS. Consequently, the monitoring, management, and maintenance of these systems become highly complex. Typically, the electronic components are grouped and housed separately from the cells, with distributed BMS technology being the preferred approach.   In distributed BMS, the electronics are integrated into the cell boards, which are contained within the cells being monitored. This design optimizes communication and computation by utilizing the communication wires between the BMS controller and cell boards. The distributed BMS minimizes the number of sensor wires and communication cables between the BMS modules, ensuring a self-contained structure for each BMS unit.     Voltage Measurement in BMS Voltage measurement is a critical function of BMS, and it benefits from precise measurement capabilities. The BMS incorporates a dedicated cell voltage acquisition module, which utilizes an analog-to-digital converter for voltage measurement. This approach is necessary because lithium-ion cells must operate within specific voltage ranges, determined by the intrinsic chemistry of each cell and the prevailing temperature conditions.   Furthermore, the SOA voltage is constrained to optimize battery lifespan when battery packs undergo current cycling, charging from different energy sources, or discharging due to high load demands. Significance of BMS in Lithium Batteries Lithium-ion batteries have gained immense popularity in recent years, establishing themselves as the leading rechargeable battery technology in the energy storage field. Their advantages, including high energy density, low self-discharge rate, long cycle life, high cell voltage, compact size, light weight, durability, and environmental friendliness, have contributed to their widespread adoption.   However, due to the high reactivity of lithium, these batteries are sensitive to temperature variations. Overcharging, overdischarging, over-temperature, short-circuiting, and other unfavorable conditions can pose safety hazards. Consequently, lithium-ion batteries are equipped with BMS to prevent overcharge, over-discharge, overcurrent, and to monitor and manage battery status. BMS ensures the safe and effective utilization of lithium-ion batteries' superior performance. Thus, BMS holds immense importance for lithium-ion batteries.   Functionality of High Voltage BMS High voltage BMS systems can manage voltages exceeding 1500 VDC within a single battery rack, especially when integrated with multi-module controllers. They measure module-level and cell-level voltage, current, and temperature. Additionally, they calculate the depth of discharge and state of charge. This information is relayed to the Power Conversion System (PCS) to enable discharge control or precise charging based on voltage requirements.   Moreover, high voltage BMS systems provide battery thresholds to the PCS, triggering warnings when safety limits are approached. This prompts the automated activation of cooling fans. Some high voltage BMS systems include a pre-charge circuit that ensures voltage matching and prevents current surges when connecting the stack to the DC bus.   Controlled Aspects of BMS Whether it is a high voltage BMS or a low-voltage variant, BMS essentially functions as an electronic regulator overseeing the charging and discharging processes of rechargeable batteries. The control features can vary depending on the system's complexity. While some BMS units may perform simple tasks such as voltage measurement and charging restriction, more advanced BMS units monitor battery performance and lifespan to ensure safer operations. They manage both multi-cell and single-cell battery systems. Multi-cell systems enable control and monitoring of individual cell packs, with some integrated with computers for advanced monitoring, including email alerts and push notifications.   Applications of High Voltage BMS High voltage BMS finds extensive usage in energy storage systems, electric vehicles, and high voltage UPS lithium batteries. It serves as the connecting link between lithium-ion batteries and manages their functionality. Furthermore, it collects system data and ensures the cells operate and balance under specific conditions. High voltage BMS systems are responsible for monitoring packtemperature, regulating circuit connections to optimize battery temperature within a narrow range, and maintaining battery performance.     Choosing a High Voltage BMS for Energy Storage Batteries Selecting the appropriate high voltage BMS depends on factors such as the size of the battery system, rated capacity, and voltage. Considerations include: Voltage: The total voltage of the battery pack is determined by the number of cells it comprises. Different applications may require specific nominal voltages. Amperage: This measures the flow of electrical current and determines the rate at which electrons pass through the circuit. It is essential to match the BMS amperage capabilities with the requirements of the battery system. Battery Capacity: Measured in milliampere-hours (mAh), battery capacity indicates the total amount of current the battery can supply within an hour before the voltage drops to a specific value. The BMS should be compatible with the battery's capacity. C-Rate: The C-rate represents the charge or discharge rate relative to the rated capacity of the battery. Consider the C-rate requirements of the battery system when selecting a high voltage BMS. By considering these factors, one can make an informed decision when choosing a high voltage BMS for energy storage batteries.   In conclusion, high voltage BMS plays a vital role in ensuring the safe and efficient operation of high voltage lithium-ion battery packs. It serves as an electronic supervisory system that monitors and manages cell parameters, protects against adverse conditions, and optimizes battery performance. With its distributed architecture, precise voltage measurement, and control capabilities, the high voltage BMS is an essential component in energy storage systems, electric vehicles, and other high voltage applications.
