摘要： An enclosed electrical device such as a battery pack for an electric powertrain system includes an enclosure having a tray and cover. The tray and cover together define an enclosure cavity. A radio frequency (RF) receiving node is located within the cavity. Printed circuit board assemblies (PCBAs) include an RF transmitting node. The PCBAs(s) are spaced apart from one another within the cavity. An RF shield guide layer is positioned between the PCBAs and the cover, such that the RF shield guide layer covers the PCBAs without covering the RF transmitting node. A battery pack and an electric powertrain system include the RF shield guide layer.
