By adopting the method, the electronic equipment can be reminded to feed back the parameter information of the electronic equipment based on the first power supply current provided by the first power supply unit, the transmission of instructions and the like between the electronic equipment and the first power supply unit is not needed, and the charging process of the electronic equipment is not influenced.
Referring to fig. 5, a flowchart of a charging method according to embodiment 4 of the present invention is shown, wherein the charging method may include the following steps:
step S501: receiving a source current provided by a power supply;
step S502: controlling a first power supply unit of the charger to provide a first power supply current for the electronic device based on the source current, so that the electronic device determines that a power supply channel is established between the charger and the electronic device based on the first power supply current;
steps S501 to 502 are the same as steps S401 to 402 in embodiment 3, and are not described in detail in this embodiment.
Step S503: starting timing from the first power supply unit which controls the charger based on the current source to provide a first power supply current for the electronic equipment, and obtaining a timing time value;
first, it should be noted that when the electronic device is a device supporting multiple power supply currents of the charger or an information transmission channel between the charger and the electronic device is normal, the electronic device feeds back parameter information when receiving the first power supply current, otherwise, the electronic device does not feed back the parameter information.
Specifically, when the first power supply unit of the charger provides the first power supply current to the electronic device to start timing, a timing time value is obtained.
It should be noted that the charger may be provided with a timer to implement its timing function.
Step S504: judging whether the parameter information is received or not when the timing time value reaches a preset threshold value, and obtaining a first judgment result;
and when the timing time reaches the preset threshold value, judging whether the charger receives the parameter information fed back by the electronic equipment.
When the timing time reaches a preset threshold value, receiving parameter information fed back by the electronic equipment, and executing steps S505-506 to realize that the charger charges the electronic equipment with multi-path power supply current; otherwise, step S507 is executed, and only one path of supply current is used to charge the electronic device.
For example, the first power supply unit may provide 5V current for the electronic device, and in the subsequent step, when the charger is controlled to provide two paths of power supply currents for the electronic device, the two paths of power supply currents may be controlled to be 5V and 9V, respectively.
It should be noted that, when the electronic device supports multiple supply currents of the charger, the multiple charging units therein can respectively receive the supply currents provided by the multiple power supply units of the charger; when the information transmission channel between the charger and the electronic equipment is normal, parameter information transmission between the charger and the electronic equipment can be realized so as to realize control over a plurality of power supply currents for the electronic equipment based on the parameter information, and when the information transmission channel between the charger and the electronic equipment is abnormal, the parameter information transmission between the charger and the electronic equipment cannot be carried out, even if the electronic equipment is provided with a plurality of charging units, because the state of the electronic equipment cannot be determined, in order to ensure the operation safety of the electronic equipment, only one path of power supply current is adopted to charge the battery of the electronic equipment.
Step S505: when the timing time value reaches a preset threshold value based on the first judgment result, receiving the parameter information, and generating control information according to the parameter information;
specifically, the control information is generated according to the parameter information and preset allocation conditions;
step S506: controlling the at least two power supply units to supply power to at least two charging units in the electronic equipment based on the control information, so that the at least two charging units respectively charge batteries in the electronic equipment;
steps S505 to 506 are the same as steps S404 to 405 in embodiment 3, and are not described in detail in this embodiment.
Step S507: and when the timing time value reaches a preset threshold value and the parameter information is not received based on the first judgment result, controlling a first power supply unit of the charger to supply a first power supply current to the electronic equipment based on the source current.
When the timing time reaches a preset threshold value and the parameter information sent by the electronic equipment is not received, it can be determined that the electronic equipment does not support a multi-path power supply current charging mode of the charger, and the first power supply unit is maintained to supply power to the electronic equipment, so that the electronic equipment is powered by adopting a multi-path power supply mode.
It should be noted that, in a specific implementation, when the first supply current provided by the charger to the electronic device in the step 502 is a standard current for charging, such as 5V, the current is maintained in the step S507 to continuously supply power to the first electronic device.
It should be noted that in the specific implementation, when the first supply current provided by the charger to the electronic device in step 502 is a small current, in this step S507, the first supply current of the first power supply unit needs to be adjusted to a standard path of supply current, for example, to be 5V.
In summary, the charging method provided in this embodiment further includes: starting timing from the first power supply unit which controls the charger based on the current source to provide a first power supply current for the electronic equipment, and obtaining a timing time value; judging whether the parameter information is received or not when the timing time value reaches a preset threshold value, and obtaining a first judgment result; when the timing time value reaches a preset threshold value based on the first judgment result, receiving the parameter information, and generating control information according to the parameter information; and when the timing time value reaches a preset threshold value and the parameter information is not received based on the first judgment result, controlling a first power supply unit of the charger to supply a first power supply current to the electronic equipment based on the source current. By adopting the method, when the parameter information fed back by the electronic equipment is received in the preset time content, the multi-path power supply mode is executed to supply power to the electronic equipment, otherwise, only one path of power supply mode is adopted to supply power to the electronic equipment, and the flexibility of charging is improved.
The parameter information may include an ambient temperature value of a preset location of the electronic device.
Referring to fig. 6, a flowchart of a charging method according to an embodiment 5 of the present invention is shown, wherein the charging method includes the following steps:
step S601: receiving parameter information provided by the electronic equipment based on an information transmission channel between the charger and the electronic equipment;
step S601 is the same as step S301 in embodiment 2, and details are not described in this embodiment.
Step S602: generating control information according to the environmental temperature value;
