摘要
In order to ensure the stability of battery management power system, improve the reliability of on-board electronic products, and ensure the stability of thermal en-ergy recovery power system, the author proposes an electromagnetic compatibil-ity optimization scheme based on wiring harness, power module, and PCB noise, taking the battery management system of vehicle electronic components as an example, the role of electromagnetic compatibility on products is described, the hardware circuit is analyzed and designed by electromagnetic compatibility design theory to ensure the reliability of vehicle components. The electromagnetic stabil-ity of the power battery is guaranteed through the electromagnetic compatibility optimization analysis of the battery management system, so as to achieve more stable battery management. The experimental results show that each module of the battery management system works stably, and the disturbance degree test shows that the resonant noise of the battery management system disappears, and there is no obvious narrowband electromagnetic disturbance, and the overall value is below the limit of 20 dB. In conclusion the electomagnetic compatibility optimiza-tion scheme can effectively ensure the stability of the battery management power system, and indirectly ensure the stability of the heat recovery power system.
