Electronic equipment, charger and charging method

A charger, comprising:

• a rectification control chip, a communication control chip and a physical charging interface, wherein
• the communication control chip and the rectification control chip are both electrically coupled with the physical charging interface;
• the communication control chip is electrically coupled with the rectification control chip;
• the communication control chip is configured to receive an encrypted charging control instruction sent by an electronic equipment coupled with the physical charging interface when it is determined that the charger is a preset charger, and decrypt the encrypted charging control instruction;
• and
• the rectification control chip is configured to control a charging current of the charger according to the decrypted charging control instruction,
• wherein the preset charger is a charger that supports a preset direct charging protocol and a Qualcomm QC protocol;
• and
• wherein the communication control chip is further configured to:
• receive authentication information of the preset direct charging protocol sent by the electronic equipment according to a Power Delivery (PD) protocol;
• acquire content in the authentication information of the preset direct charging protocol through the PD protocol;
• and
• send response information of the preset direct charging protocol to the electronic equipment based on the content according to the PD protocol.

A charging method for use with an electronic equipment, the method comprising:

• determining, by a processor, a type of a charger coupled with a physical charging interface through a communication control chip and one or more charging chips;
• and
• setting, by the processor, a direct charging control switch to an ON state when the charger is a preset charger, and controlling the charger to perform charging according to a first charging mode;
• or
• setting, by the processor, the direct charging control switch into an OFF state when the charger is not the preset charger, and performing charging through the one or more charging chips according to a second charging mode,
• wherein the processor determines the type of the charger by:
• detecting whether the charger supports a preset direct charging protocol through the communication control chip by:
• sending authentication information of the preset direct charging protocol to the charger according to a Power Delivery (PD) protocol, and receiving response information of the preset direct charging protocol sent by the charger according to the PD protocol;
• detecting whether the charger supports a Qualcomm QC protocol through the one or more charging chips;
• determining that the charger is a preset charger if the charger supports the preset direct charging protocol and the Qualcomm QC protocol;
• determining that the charger is a high-voltage charger if the charger does not support the preset direct charging protocol but supports the Qualcomm QC protocol;
• and
• determining that the charger is an ordinary charger if the charger does not support the preset direct charging protocol and the Qualcomm QC protocol.
