I know they're talking about EMI and not radiated emissions but if even a tiny fraction of a fraction of the EMI does get radiated the widespread adoption of electrical vehicles will probably raise the noise floor in the HF bands significantly.
- londons_explore 4y agoSome of it will be radiated. Electric currents in EV's are typically in the hundreds of amps, and have potential switched by hundreds of volts in hundreds of nanoseconds. That leads to broad band emissions that aren't easy to shield. A bunch of ferrites and shielded motors and cables will help, but only to some extent.
- shadowpho 4y ago>hundreds of nanoseconds Do you have any sources for this? Would love to learn more, as that seems extremely fast.
