Application | N62100 High-Performance Electronic Load in Fast-Charging Adapter Testing

With the widespread adoption of smartphones and tablets, fast-charging technology has become essential. Charging power continues to break recordsfrom 20W to 240W,posing unprecedented challenges for adapter performance testing. Market research indicates the fast-charging adapter market will maintain rapid growth in coming years, expanding its share in mobile accessories.

As the core component of fast-charging systems, adapters' performance and safety directly impact charging efficiency, device lifespan, and user safety. This article examines key aspects of fast-charging technology and its testing challenges.

1.  Fast-Charging Fundamentals
Fast-charging reduces charging time by increasing power through elevated voltage (up to 20V) and current (up to 12A). Compared to conventional methods, it can shorten charging time by 50-70%. Major global standards include:

2.  Testing Challenges

①Protocol Complexity: Multiple competing standards (USB PD, QC, PE, etc.) require test equipment with broad compatibility

②Oscillation Risks:Insufficient output capacitance or slow load current responsemay cause oscillation and device damage

③Measurement Requirements: Needs high-precision simulation of complete charging cycles (CC/CV/trickle) with accurate voltage/current/power/ripple measurements
