Wireless chargers, charging pads, multi-device charging stations, and fast charging adapters are covered under IS/IEC 62368-1:2023 for BIS CRS registration.
Wireless charging generates heat through electromagnetic induction. The transmitter coil, receiver coil, and the space between them all experience thermal effects. IS/IEC 62368-1:2023 evaluates:
Gallium Nitride (GaN) chargers achieve high power output (65W, 100W, 140W) in very compact form factors. The compact design means thermal management is more challenging — components run hotter in a smaller space. IS/IEC 62368-1:2023 thermal evaluation is particularly rigorous for high-power GaN chargers.
USB-C Power Delivery chargers must safely negotiate the correct voltage and current with connected devices. The PD controller, cable detection, and voltage regulation under fault conditions are evaluated.
If you sell a wireless charger packaged with a USB-C cable, both the charger and the cable may need separate BIS registrations. Confirm with your lab whether the cable needs independent certification or is covered under the charger system registration. House of Testing handles IS 62368 charger testing.
