Embodiment Construction

[0066] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0067] It should be noted that when an element is referred to as being “electrically connected” to another element, it may be directly on the other component or there may be an intervening element. When an element is considered to be "electrically connected" to another element, it may be connected by contact, eg, by a wire connection, or non-contact, eg, by a non-contact coupling.

[0068] Unless otherwise defined, all technical and scientific terms used herei...

Abstract

The invention provides a charger comprising a power supply output interface, a signal interface, a balance charging interface, and a control circuit; the control circuit is respectively electrically connected with the power supply output interface, the signal interface, and the balance charging interface; the power supply output interface is used for outputting charging signals; the signal interface is used for obtaining charging information of the battery; the balance charging interface is used for control charging balance for all cells of the battery; the control circuit can select the signal interface and the balance charging interface according to the battery type, thus controlling charging of the battery. The invention also provides a charging system and an aircraft having the charging system.

Description

technical field [0001] The invention relates to a control circuit, a battery with the control circuit and a battery control method. Background technique [0002] Batteries currently on the market usually add a control circuit to the battery cell to realize various circuit functions such as the minimum discharge voltage limit of the battery cell, the maximum charge voltage limit, temperature and current detection. However, when the electric core is not powered externally, the control circuit is still in working state. For example, the control unit in the control circuit needs to regularly monitor the state information of the battery cell and store the state information in a register. When the battery cell is not powered externally, the control circuit will still generate corresponding power consumption. At this time, the battery is still in a state of power consumption. [0003] The commonly used solution at present is that when the battery is in a power-off state, the cont...
