摘要:
随着新能源汽车产业的快速发展，动力电池检测设备的准确性对电池全生命周期管理至关重要。针对现有检测设备因缺乏标准化校准导致的系统性误差问题，该文提出了一种基于CAN总线通信协议的动力电池检测设备校验装置研究方案。该装置采用双模式切换架构，通过标准电压源与负载模块协同工作，结合多阵列传感器与 A/D 转换模块实现多维度电气参数（电压、电流、温度及 SOC等）的高精度采集与分析。基于GB/T 27930—2023协议，开发了BMS报文动态模拟系统，可重构电压、温度、荷电状态（SOC）等关键参数的数据帧，构建理想电池模型以模拟实际工况，通过工况模拟与多维度参数重构技术，实现检测设备的系统性误差校准。实验结果表明，电源电路在输入电压波动 ±15% 时，输出电压误差≤1%，满足 GB/T 38330—2019 标准要求；CAN报文模拟功能可精确重构 BMS 通信参数，与检测设备交互误差控制在 1% 以内。该装置为动力电池研发、生产及回收环节提供了可靠的校验手段，对推动电动汽车后市场服务规范化和产业可持续发展具有重要意义。
Abstract:
With the rapid development of new energy vehicle industry, the accuracy of power battery testing equipment is crucial for the full life cycle management of batteries. Aiming at the systematic errors caused by the lack of standardized calibration of the existing testing equipment, this paper proposes a research program of power battery testing equipment calibration device based on CAN bus communication protocol. The device adopts a dual-mode switching architecture, working with a standard voltage source and a load module, and combining a multi-array sensor with an A/D converter module to realize high-precision acquisition and analysis of multi-dimensional electrical parameters (voltage, current, temperature and SOC, etc.). Based on the GB/T 27930—2023 protocol, a dynamic simulation system for BMS telegrams is developed, which can reconstruct the data frames of key parameters such as voltage, temperature, state of charge (SOC), etc., construct an ideal battery model to simulate the actual working conditions, and realize the systematic error calibration of the testing equipment through the simulation of the working conditions and the reconstruction of multi-dimensional parameters. The experimental results show that the output voltage error of the power supply circuit is ≤1% when the input voltage fluctuates ±15%, which meets the requirements of GB/T 38330—2019 standard. The CAN telegram simulation function can accurately reconstruct the BMS communication parameters, and the interaction error with the testing equipment is controlled within 5%. The device provides a reliable means of calibration for power battery R&D, production and recycling, and is of great significance in promoting the standardization of electric vehicle after-market services and the sustainable development of the industry.
