[0051] The following gives an example to illustrate a specific implementation manner of the present invention. It should be noted that other equivalent implementation manners also belong to the protection scope of the present invention, and the protection scope of the present invention should not be limited to the specific implementation manner exemplified.

[0052] A charging method capable of automatically identifying an adapter and photovoltaic input, comprising the following steps:

[0053] S1. The photovoltaic and adapter judgment device receives a trigger signal;

[0054] S2. Judge whether the charging initialization is completed. If the charging initialization is completed, execute step S3. If the charging initialization is not completed, perform the charging initialization operation and then exit. Wherein, the charging initialization includes giving the initial charging voltage and initial charging current of the energy storage device; specifically, the initial charging voltage can be the floating charge voltage of the machine, and the charging current can be 0.1 - 2A, preferably 0.5 - 1.5A. The initial charging current cannot be too large, otherwise some adapters cannot work properly. If it is too small, the charging speed will be reduced;

[0055] S3. Judge whether the voltage of the charging port meets the charging conditions. If it meets, issue a power - on command and start the timer to start timing. If not, end the operation;

[0056] S4. Judge whether the timing time of the timer is greater than the first threshold value. If it is, exit the operation. If not, execute step S5. Among them, the first threshold value can be 1 - 15s, preferably 3 - 8s;

[0057] S5. Judge whether the first voltage value is less than or equal to the second voltage value. Wherein, the first voltage value is the current charging port voltage, and the second voltage value is the difference between the charging port voltage before power - on and the photovoltaic input port voltage drop reference value. If it is, set the photovoltaic charging mode flag to 1 and then exit the operation. Otherwise, set the adapter charging mode flag to 1 and then exit the operation.

[0058] In some embodiments of the present invention, step S2 further includes:

[0059] S21. Receive the first real - time sampling data sent by the energy storage device, where the first real - time sampling data includes the charging voltage and charging current of the energy storage device; specifically, the current charging voltage and charging current can be collected in real - time by the voltage sampling circuit and current sampling circuit of the energy storage device;

[0060] S22. Compare the charging voltage and charging current with the given initial charging voltage and initial charging current, and judge whether the charging initialization state is completed. For example, compare whether the charging voltage reaches the floating charge voltage of the machine and whether the charging current is within 0.1 - 2A. If so, the charging initialization state is completed.

[0061] In some embodiments of the present invention, step S3 further includes:

[0062] S31. When the charging initialization state is the end state, receive the second real-time sampling data sent by the energy storage device before sending the power-on instruction, where the second real-time sampling data includes the charging port voltage;

[0063] S32. Determine whether the charging port voltage meets the charging conditions. If it meets the conditions, send the power-on instruction; otherwise, exit the operation.

[0064] In some embodiments of the present invention, step S5 further includes:

[0065] S51. Receive the current charging port voltage collected by the voltage sampling circuit of the energy storage device;

[0066] S52. Compare the first voltage value with the second voltage value, where the first voltage value is the current charging port voltage, and the second voltage value is the difference between the charging port voltage before power-on and the photovoltaic input port voltage drop reference value. The photovoltaic input port voltage drop reference value can be a system preset value or obtained through arithmetic processing based on the photovoltaic charging port voltage data stored in the system; when the photovoltaic input port voltage drop reference value is a system preset value, this preset value can be an empirical value obtained through multiple experiments based on the characteristics of the photovoltaic panels, and its range can be 0.1 - 5V, preferably 0.5 - 2V; when the photovoltaic input port voltage drop reference value is obtained through arithmetic processing based on the photovoltaic charging port voltage data stored in the system, the photovoltaic input port voltage drop reference value can be obtained through the following formula: U temp =K*(U Pold -U Pnow ), where U Pold is the charging port voltage before the previous power-on stored in the system, U Pnow is the photovoltaic input port voltage after the previous power-on stored in the system, K is an empirical coefficient, and the calculated U temp range should theoretically be 0.1 - 5V, preferably 0.5 - 2V.
