电池监测产品的可靠性研究

Reliability Study of Battery Monitoring Products

为保障电池系统的可靠运行,对电池监测产品自身的可靠性进行研究。鉴于测量原理及其工作环境的特殊性,通过对实际产品的研制、认证、应用过程进行分析与改进,详细描述了电池监测产品采样前端的过压、共模干扰、串模干扰模型,并给出抑制措施;讨论了关键信号负过冲的解决方案;说明了结构与线缆的设计要点;强调了HALT试验的重要性。实践表明,相关设计提高了电池监测产品的可靠性及安全运维性。

For the battery system working reliably, study on the reliability of the battery monitoring product itself. In view of its particularity on measurement principle and working environment, and based on the analysis and improvement in actual product development, certification, and applications, the paper described the models in detail about the over-voltage, common mode interference, series mode interference on the sample ports of the battery monitoring product, gave the suppression methods;and discussed the solutions to the undershoot of the key signals;Also explained the design essentials of the structure and cable. Finally, emphasized the importance of HALT experiment. Practice has showed that these designs enhanced the reliability and ensured safety maintenance.
