Embodiment Construction

[0019] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments, but not as a limitation of the present invention.

[0020] Please refer to figure 1 , the present invention provides a battery life control method, including: judging whether the system is in the off-grid state; in the case of the system in the off-grid state, judging whether the power generation is less than the power consumption; if the power generation is less than the power consumption, and the battery If the sum of the electric power and the power generation is greater than the power consumption, the battery is connected to the circuit; otherwise, the battery is connected to the circuit, and at least part of the adjustable circuit is turned off so that the sum of the power and power generation of the battery is greater than the power consumption. Preferably, the off-grid state refers to a state in which the power generation is zero...

Abstract

The invention discloses a battery life control method and device. The battery life control method includes: judging whether the system is in the off-grid state; in the case of the system being in the off-grid state, judging whether the power generation is less than the power consumption; If the sum is greater than the power consumption, then connect the storage battery to the circuit; otherwise, connect the storage battery to the circuit and close at least a part of the adjustable circuit so that the sum of the storage battery power and the power generation is greater than the power consumption. When the system is in the off-grid state, the present invention can enable the system to automatically perform endurance control on the premise of ensuring battery life, and select a solution with optimal power consumption to ensure the user's power consumption time.

Description

technical field [0001] The present invention relates to the field of power supply management, in particular to a battery life control method and device. Background technique [0002] In the prior art, when the system is offline (that is, the grid does not supply power to the circuit or the power provided by the grid is not enough to meet the power demand of the circuit), the user's power consumption time cannot be guaranteed. Contents of the invention [0003] Embodiments of the present invention provide a battery life control method and device to solve the problem in the prior art that the user's power consumption duration cannot be guaranteed in an offline state. [0004] In order to solve the above technical problems, an embodiment of the present invention provides a battery life control method, including: judging whether the system is in an off-grid state; when the system is in an off-grid state, judging whether the power generation is less than the power consumption; ...
