high-accuracy survey：Industrial and commercial energy storage systems require precise knowledge of the battery's charging and discharging status in order to achieve optimal energy management. The Hix Magnetic Current Sensor has high-precision measurement capabilities and can accurately monitor the current changes during the battery charging and discharging process, providing precise data to the Battery Management System (BMS), helping the BMS accurately calculate the battery's state of charge (SOC) and charging and discharging capacity, avoiding overcharging or overdischarging, and extending the battery life. For example, in large industrial and commercial energy storage stations, through the precise measurement of the Hix Magnetic Current Sensor, the charging and discharging control accuracy of the battery group can reach a very high level, ensuring the stability of the overall performance of the battery group and the extension of its lifespan.
quick response：In industrial and commercial energy storage systems, when faults such as overload or short circuit occur, it is necessary to quickly detect and take protective measures. The Hixi Magnetic Current Sensor has a fast response speed and can detect sudden changes in current within a short period of time. It can promptly send alarm signals to the system or trigger protection mechanisms to ensure the safety of the energy storage equipment and the entire system. For example, when an abnormal current occurs in a certain branch of the energy storage system, the Hixi Magnetic Current Sensor can detect it within microseconds and transmit the signal to the control system, enabling the system to take rapid measures, such as cutting off the faulty branch to prevent the expansion of the fault.
Wide measurement range：The current range of industrial and commercial energy storage systems is quite wide, ranging from the small current float charging of the battery to the large current during high-rate charging and discharging. The magnetic current sensor has a wide measurement range and can meet the current measurement requirements under different working conditions. Whether it is during the initial charging stage of the battery or the stage of full-load discharge and power supply to the grid, it can accurately measure the current, providing reliable data support for the stable operation of the system.
High reliability and stability：Industrial and commercial energy storage systems usually require long-term stable operation, and have high requirements for the reliability and stability of sensors. The Hixi Magnetic Current Sensor adopts high-quality materials and advanced manufacturing processes, possesses excellent anti-interference ability and environmental adaptability, and can operate stably in complex electromagnetic environments and harsh working conditions. For instance, in some industrial environments, there are strong electromagnetic interferences and significant variations in temperature and humidity. The Hixi Magnetic Current Sensor can remain unaffected by these factors and maintain stable performance, ensuring the reliable operation of the energy storage system.
Battery pack monitoring：Connected to the charging and discharging circuit of the battery pack, it can monitor the charging and discharging current of the battery pack in real time, helping the BMS achieve precise management of the battery pack, including SOC estimation, charging and discharging control, overcurrent protection, etc.
Connect the energy storage converter（PCS）：Installed on the AC and DC sides of the PCS, it is used to monitor the current between the PCS and the power grid, as well as between the PCS and the battery pack. This enables precise control and protection of the PCS, ensuring its stable operation in different working modes and improving the efficiency of energy conversion.
The combined application of distributed power generation systems and energy storage：In the joint application of distributed power generation systems (such as photovoltaic and wind power) and energy storage systems, the Hime magnetic current sensor can be used to monitor the output current of distributed power sources and the charging and discharging current of the energy storage system, enabling coordinated control of distributed power generation and energy storage, and improving energy utilization efficiency and system stability.
