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 / 3.0 protocol usually do not support VOOC (Voltage Open Loop Multi-step Constant-Current Charging, voltage open loop multi-step constant current charging) Charging) protocol scheme and Pump Express 2.0 / 3.0 fast charging protocol, (referred to as PE+2.0 / 3.0), that is, it can only be used with chargers that support QC 2.0 / 3.0 protocol to achieve fast charging, and cannot be used with chargers that support VOOC protocol and PE+2.0 / 3.0 protocol charger for fast charging
Mobile phones that support VOOC protocol solutions usually do not support QC2.0 / 3.0 protocol solutions and PE+2.0 / 3.0 protocol solutions, that is, they can only be used with chargers that support VOOC protocol to achieve fast charging, and cannot be matched with chargers that support QC2.0 / 3.0 protocols and Charger with PE+2.0 / 3.0 protocol for fast charging
Mobile phones that support the PE+2.0 protocol solution usually do not support the QC2.0 / 3.0 protocol solution and VOOC protocol solution, that is, they can only be used with chargers that support the PE+2.0 / 3.0 protocol to achieve fast charging, and cannot be matched with QC2.0 / 3.0. Charger with protocol and VOOC protocol for fast charging
Therefore, existing electronic devices are less compatible with chargers

Abstract

The present invention discloses an electronic device. The electronic device comprises a charging module, a CPU (Central Processing Unit) and an MCU (Micro Control Unit); the charging module is connected with a charger; the CPU is connected with the charger and is used for detecting the port type of the charger connected with the CPU and obtaining charging current corresponding to the port type from the charger according to the port type of the charger so as to charge the electronic device; the MCU is connected with the charger; and the MCU is used for detecting a special charging protocol supported by the charger when it is detected that the charger is a charger with a special charging port, and selecting a corresponding special charging protocol scheme to control the charger to charge the electronic device. The present invention also provides a charging method. With the charging method adopted, the electronic device of the present invention is compatible with various fast charging protocols.
