WASHINGTON, Sept 10 (Reuters) - U.S. officials say solar-powered highway infrastructure including chargers, roadside weather stations, and traffic cameras should be scanned for the presence of rogue devices such as hidden radios secreted inside batteries and inverters.
The four-page security note, a copy of which was reviewed by Reuters, said that undocumented cellular radios had been discovered in certain foreign-manufactured power inverters and BMS, referring to battery management systems.

Well, if you takes those apart, the quickest way to tell that is to find at the edge of a PC board a 2" foil trace, that terminates to nothing, at one end, and just an SMT chip CAP at the other. That, would be the antenna.

Part of me says, yeah, looks like a problem, just as the hidden spy chips in Chinese made PCB's that were destined for sensitive Naval equipment (the chips were complete spychips, made small and shaped to look like diodes or SMT transistors) were a problem.
On the other hand, every smartphone, modern car, many modern flatscreens, and other devices are spying on everybody already.
What's the difference, really? It's all a matter of who's selling the data to whom.
