Abstract

A battery management system design and test scheme are proposed to meet the test requirements for high-precision state-of-energy (SOE) calculation in energy storage systems and enable joint debugging with the power system. The proposed system’s hardware and software design, along with the testing scheme using RTDS as the main control logic, are presented. In this design, the SOE value of the single unit can be calculated using the extended Kalman algorithm and other correction methods in the energy storage system with multiple strings. The experimental results show that the SOE error is 1.5% under the condition of constant power test at room temperature. Additionally, the RTDS battery model simulates battery data, and the high-pressure box control logic is integrated into RTDS to enable direct control of the RTDS battery cluster output voltage via the battery management system.

基于FreeRTOS和RTDS测试系统的电网储能电池管理系统设计

为满足储能系统中高精度能量状态（SOE）计算的测试需求，并实现与电力系统的联合调试，提出了一种电池管理系统设计与测试方案。给出了系统的硬件和软件设计，并给出了以RTDS为主要控制逻辑的测试方案。在本设计中，在多串储能系统中，可采用扩展卡尔曼算法等校正方法计算单机SOE值。实验结果表明，在室温恒功率测试条件下，SOE误差为1.5%。此外，RTDS电池模型对电池数据进行仿真，并将高压箱控制逻辑集成到RTDS中，通过电池管理系统直接控制RTDS电池组输出电压。

期刊介绍： IEEE Access® is a multidisciplinary, open access (OA), applications-oriented, all-electronic archival journal that continuously presents the results of original research or development across all of IEEE''s fields of interest. IEEE Access will publish articles that are of high interest to readers, original, technically correct, and clearly presented. Supported by author publication charges (APC), its hallmarks are a rapid peer review and publication process with open access to all readers. Unlike IEEE''s traditional Transactions or Journals, reviews are "binary", in that reviewers will either Accept or Reject an article in the form it is submitted in order to achieve rapid turnaround. Especially encouraged are submissions on: Multidisciplinary topics, or applications-oriented articles and negative results that do not fit within the scope of IEEE''s traditional journals. Practical articles discussing new experiments or measurement techniques, interesting solutions to engineering. Development of new or improved fabrication or manufacturing techniques. Reviews or survey articles of new or evolving fields oriented to assist others in understanding the new area.
