Embodiment Construction
[0024] The technical solutions in the embodiments of the present invention will be clearly described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.
[0025] It should be noted that when a component is said to be "fixed to" another component, it can be directly on the other component or a central component may also exist. When a component is considered to be "connected" to another component, it can be directly connected to another component or there may be a centered component at the same time. When an element is said to be "electrically connected" to another element, it can be directly on the other ...

The invention discloses an active equalization control circuit, method and device, a battery, an object and a storage medium. The equalization circuit comprises a control circuit (202), and the control circuit (202) is used for collecting parameters of at least one battery unit (1082) in the plurality of battery units (1082), and generating a corresponding control signal according to the parameters. The equalization circuit (204) is used for selecting at least one battery unit (1082) in the plurality of battery units (1082) according to the control signal so as to carry out electric quantity management on the battery unit (1082). The control circuit (202) generates the control signal. When the equalization circuit (204) obtains the control signal, the equalization circuit (204) can be electrically connected with the battery unit (1082), and the equalization circuit (204) can carry out electric quantity management on the battery unit (1082) and can heat a to-be-heated part at the same time. According to the technical scheme of the embodiment of the invention, the layout area of the equalization circuit is optimized, the battery management efficiency is improved, and the service lifeof the battery is prolonged.
Description
Technical field [0001] The embodiment of the present invention relates to the field of control technology, in particular to an active balance control circuit, a battery management method, a battery management device, a smart battery, a movable object, and a computer-readable storage medium. Background technique [0002] Rechargeable batteries are widely used in various electrical equipment due to the advantages of small size, large capacity, high reliability and repeated use of charging. However, the battery's own capacity and / or voltage are not balanced during use, which affects the use of electrical equipment. [0003] In traditional technologies, active balancing schemes and passive balancing schemes are used to solve the problem of battery imbalance. The working principle of passive balancing is to achieve capacity balancing by switching and controlling the power consumption resistance of cells with relatively high capacity. The typical balancing capacity is 0.25% SOC / hour to ...
