Second Category: Part 15 Unintentional Radiators

Question:   Is a battery charger and associated digital electronics on-board a vehicle that is used for charging the vehicles battery while parked and connected to AC power lines exempt from an equipment authorization under 15.103.


No. Section 15.103, Exclusions, paragraph (a) does not apply to battery chargers for electric vehicles that can be used for charging while stationary and connected to an AC power line. The exemption is only intended for digital devices which operate primarily when the vehicle is operating in a mobile environment such as on a road or highway where the potential for interference is low. When stationary and connected to the AC power line, typically in a residential environment such as a home garage or driveway, the potential for interference by both AC lines conducted and radiated emissions is greater. The battery chargers and associated electronics on board an electric vehicle are therefore subject to an equipment authorization under the verification procedure as a Part 15  Class B or Class A (industrial vehicles) unintentional radiator (switching power supply and digital device).
