Problems solved by technology

[0002] Existing electronic devices such as mobile phones usually only support one fast charging protocol. For example, mobile phones that support the QC 2.0 protocol usually do not support VOOC (Voltage Open Loop Multi-step Constant-Current Charging, voltage open loop multi-step constant current charging) Protocol solution, that is, it can only be used with a charger that supports the QC 2.0 protocol to achieve fast charging, and cannot be used with a charger that supports the VOOC protocol for fast charging
Mobile phones that support the VOOC protocol solution usually do not support the QC2.0 protocol solution, that is, they can only be used with chargers that support the VOOC protocol for fast charging, and cannot be used with chargers that support the QC2.0 protocol for fast charging.
Therefore, existing electronic devices are less compatible with chargers

Abstract

The invention discloses an electronic device. The electronic device comprises a charging module, a CPU (Central Processing Unit) and an MCU (Micro Controller Unit), wherein the charging module is used for connecting with a charger, the CPU is connected with the charging module and is used for controlling the charging module to detect a port type of the charger connected with the CPU, acquiring a charging current corresponding to the port type from the charger according to the port type of the charger and charging the electronic device, the MCU is connected with the charging module, and the MCU and the charging module are also used for further detecting a special charging protocol supported by the charger and selecting a corresponding special charging protocol scheme to control the charger to charge the electronic device when the fact that the port type of the charger is a special charging port type is detected by the charging module. The invention also provides a charging method.
