In the embodiment of the application, generally, for an electrical appliance, for example, a storage battery is internally provided with a power management chip, rated charging voltage information corresponding to the storage battery can be stored in the power management chip, and when the storage battery is connected to a charging pile, an electronic device can obtain the rated charging voltage of the storage battery through a charging state; similarly, this method can be applied to any load in which a power management chip is installed and rated charging voltage information is prestored.

In the embodiment of the present application, the user may input the first charging signal including the rated charging voltage through an input device, including but not limited to a mouse, a keyboard, and a touch screen.
Step S1013, receiving a second charging signal input by a user, wherein the second charging signal comprises a load model;
step 1014, determining a rated charging voltage corresponding to the rated load model based on the load model and a preset mapping relation between each load model and the corresponding rated charging voltage.
In this embodiment of the application, if the user does not know the rated charging voltage of the load, the user may input the second charging signal including the type of the load, and the electronic device may obtain the rated charging voltage corresponding to the type of the load based on the mapping relationship between the preset load type and the corresponding rated charging voltage. The load model may be, for example, a model of a storage battery, or a model of a vehicle, and this is not limited in this embodiment, as long as the effect of facilitating the electronic device to determine the rated charging voltage of the load is achieved.
Step S102, determining output voltage of the charging pile based on rated charging voltage and preset normal voltage, wherein the output voltage is used for charging a load, and the normal voltage is the highest voltage output by the charging pile in a stable state;
and S103, controlling the charging pile to charge the load based on the output voltage.
In the embodiment of the present application, whether the rated charging voltage can be used as the output voltage depends on the magnitude relationship between the rated charging voltage and the normal voltage. For example, the output voltage may be determined as a rated charging voltage of the load, or may be a preset value, as long as the output voltage is compared with the output voltage fixed by the charging pile, the charging efficiency of the load can be improved, and the specific manner of determining the output voltage is described in the following embodiments.
Specifically, in the related art, when different loads are charged through the charging pile, because the output voltage of the charging pile is a fixed value or a fixed interval, there is a possibility that the rated charging voltage of the load is higher, but the output voltage of the charging pile is smaller, and further the charging efficiency of the load is low. In the embodiment of the application, compared with the related art, the electronic device can firstly obtain the rated charging voltage of the load, and then adjust the output voltage of the charging pile based on the rated charging voltage, so that the output voltage is not less than the rated charging voltage of the load, the probability that the load with higher rated charging voltage is charged under lower voltage is reduced, the efficiency of charging the load can be improved, and the time for charging the load to a full state is saved.
Further, step S1O2 may include step S1021 (not shown in the figure) -step S1025 (not shown in the figure), wherein:
step S1021, judging whether the rated charging voltage is larger than the normal voltage;
in this application embodiment, fill electric pile and preset normal state voltage, that is to say, fill electric pile and can last stable work under the state of output normal state voltage the most. The specific value of the normal voltage is not limited in any way in the embodiments of the present application.
Step S1022, if the rated charging voltage is smaller than the preset normal voltage, the output voltage is adjusted to the rated charging voltage. If the rated charging voltage is less than the preset normal voltage, that is to say, the charging pile takes the rated charging voltage as the output voltage, and can stably work for a long time under the state.
Step S1023, if the rated charging voltage is greater than a preset normal voltage, determining a difference between the rated charging voltage and the normal voltage to obtain a first difference.
In the embodiment of the present application, the difference is an unagnetic number, that is, the normal voltage and the rated charging voltage are first subtracted, and then the absolute value is obtained as the first difference.
Step S1024, judging whether the first difference value is smaller than a preset safety value;
step S1025, if the first difference is smaller than the preset safety value, determining that the output voltage is a normal voltage.
In this embodiment of the present application, the safety value may be set and modified by a user, that is, the charging pile may stably operate for a period of time, for example, 1 hour, 2 hours, etc., in a state where the output voltage is the normal voltage + the preset value, and for the period of time and the specific numerical value of the safety value, no specific limitation is imposed in this embodiment of the present application as long as the state of the charging pile is stable and safe. Therefore, when the first difference is smaller than the safety value, the load can be charged by directly using the rated charging voltage as the output voltage of the charging pile. If the rated charging voltage is greater than the normal voltage and the first difference value is greater than the preset value, the output voltage of the charging pile at the moment should be the normal voltage plus the preset value.
Further, the method further comprises a step S104 (not shown in the figure) and a step S105 (not shown in the figure), wherein:
step S104, receiving a voltage regulating instruction input by a user, wherein the voltage regulating instruction comprises a regulated voltage;
and step S105, determining the regulated voltage as an output voltage.
In this embodiment of the application, a user can input a voltage regulation instruction including a regulation voltage through the input device in step S1O12, and if the regulation voltage input by the user is smaller than the rated charging voltage of the load and smaller than the normal voltage, the output voltage of the charging pile is regulated to the regulation voltage. And if the adjusting voltage is greater than the rated charging voltage and smaller than the normal voltage, adjusting the output voltage of the charging pile to the adjusting voltage.
Further, if the regulated voltage is greater than the normal voltage, the following steps S106 (not shown) and S107 (not shown) are performed, wherein:
step S106, determining a difference value between the regulated voltage and the normal voltage to obtain a second difference value;
step S107, judging whether the second difference value is smaller than a safety value; if yes, determining the adjusting voltage as the output voltage.
Further, the method further comprises step SA (not shown), step SB (not shown), and step SC (not shown), wherein:
and step SA, judging whether the output voltage is greater than the rated charging voltage.
Specifically, in the embodiment of the present application, although the load can be charged in a state higher than the rated charging voltage, the inside of the load is damaged if the time is too long, and meanwhile, a potential safety hazard also exists. Therefore, the output voltage of the charging pile and the rated charging voltage should be judged.
Step SB, if the output voltage is larger than the rated charging voltage, acquiring the time for the charging pile to start outputting the voltage;
and step SC, adjusting the output voltage to be the rated charging voltage after the preset time length.
In the embodiment of the application, the time when the charging pile starts to output the voltage can be acquired by a network, can also be acquired by a preset electronic clock, and can also be input by a user. Therefore, if the load is charged with a voltage higher than the rated charging voltage, only a preset duration is allowed, that is, on the premise of improving the charging efficiency of the load, the damage to the load is also reduced.
