If the available capacity of the energy storage unit is determined based on the charge and discharge information over a longer period of time, the error between the available capacity and the latest available capacity of the energy storage unit is large. In order to reduce the error in calculating the available capacity of the energy storage unit, the present application proposes to determine the available capacity of the energy storage unit based on the charge and discharge information of the energy storage unit in the shortest and most recent time period.

[0064] S0003. Repeat the detection of the power state of the energy storage unit at the next moment. If the energy storage unit is not in the opposite state of the first power state at the fourth moment, and the duration between the fourth moment and the first moment is greater than the preset duration, the record mark is modified to a non-recording state, and a new first moment is re-determined, wherein the new first moment is located after the fourth moment.

If the state of the energy storage unit at the current moment is not the first power state, take the next moment after the current moment as the new current moment, and re-execute the detection of the state of the energy storage unit at the current moment. If the state of the energy storage unit at the current moment is the first power state, and it is the empty power state in the first power state, then the current moment is determined as the first moment. Obtain a reference moment at a preset time length of the first moment, where the time length between the first moment and the reference moment is equal to the preset time length.

[0069] Determine whether the next moment after the first moment is before the reference moment, and if so, determine the state of the energy storage unit at the next moment after the first moment, wherein the next moment being equal to the reference moment is regarded as being before the reference moment.

[0070] If it is an empty power state, the first moment is updated with the next moment, and the reference moment of the preset duration of the first moment is obtained, where the duration between the first moment and the reference moment is equal to the preset duration. It is determined whether the next moment of the first moment is before the reference moment, and if so, the state of the energy storage unit of the next moment of the first moment is determined.

[0071] If it is in the full power state, the next moment is taken as the second moment, wherein the second moment is the moment of the full power state. The charge and discharge information between the first moment and the second moment is obtained, and the available capacity of the energy storage unit is determined based on the charge and discharge information.

[0072] If it is neither a full power state nor an empty power state, the next moment of the next moment is taken as a new next moment, and the state of the energy storage unit at the next moment of the first moment is continued to be determined.

[0073] If not, the next moment after the next moment is taken as the new current moment, and the detection of the state of the energy storage unit at the current moment is continued.

If the state of the energy storage unit at the current moment is the first power state, and it is the full power state in the first power state, then the current moment is determined as the first moment. Obtain a reference moment at a preset time length of the first moment, where the time length between the first moment and the reference moment is equal to the preset time length.

[0076] Determine whether the next moment after the first moment is before the reference moment, and if so, determine the state of the energy storage unit at the next moment after the first moment, wherein the next moment being equal to the reference moment is regarded as being before the reference moment.

[0077] If it is in the full power state, the first moment is updated with the next moment, and the reference moment of the preset time length of the first moment is obtained, where the time length between the first moment and the reference moment is equal to the preset time length. It is determined whether the next moment of the first moment is before the reference moment, and if so, the state of the energy storage unit of the next moment of the first moment is determined.

[0078] If it is an empty power state, the next moment is taken as a second moment, wherein the second moment is a full power state moment. The charge and discharge information between the first moment and the second moment is obtained, and the available capacity of the energy storage unit is determined based on the charge and discharge information.

[0079] If it is neither a full power state nor an empty power state, the next moment of the next moment is taken as the new next moment, and the state of the energy storage unit at the next moment of the first moment is continued to be determined.

[0080] If not, the next moment after the next moment is taken as the new current moment, and the detection of the state of the energy storage unit at the current moment is continued.

[0081] In summary, the solution provided by the present application is to obtain the first moment when the energy storage unit is in the first power state, the first power state is an empty power state or a full power state, wherein, if the discharge power of the energy storage unit during the discharge period is 0, the first power state is an empty power state, and if the charging power of the energy storage unit during the charging period is 0, the first power state is a full power state; if it is detected that the energy storage unit is in the opposite state of the first power state at the second moment after the first moment, the charge and discharge information between the first moment and the second moment is obtained; the available capacity of the energy storage unit is determined based on the charge and discharge information; wherein, the duration between the first moment and the second moment is not greater than the preset duration.
