Abstract

一种线缆通流能力的检测方法及电子设备，其中方法包括：在电子设备与电源适配器通过充电线缆连接后，当电子设备的充电电池的充电电流为第一充电电流时，获取电子设备的第一输入电压和第一输入电流，其中，第一充电电流大于充电电池的预设倍数的充电限流值(201)；将充电电池的充电电流由第一充电电流调整为第二充电电流(202)；当充电电池的充电电流为第二充电电流时，获取电子设备的第二输入电压和第二输入电流(203)；根据第一输入电压、第一输入电流、第二输入电压和第二输入电流，计算充电线缆的电阻，并根据所计算得到的电阻确定充电线缆的电流通流量(204)，由此可以快速确定充电线缆(103)的通流能力，且无需改变电子设备(101)或者线缆的结构，兼容性好。
