Problems solved by technology

[0002] At present, it is gradually tending to connect batteries of different sizes and capacities in series and parallel to form a battery pack (Pack), and in a battery pack, since the capacity of the batteries may be different, the impedance may also be different, the different battery cells The magnification may also be different, and it is easy to exceed the magnification output, resulting in accelerated decay of the battery pack and reduced service life
However, there is currently no effective solution that can achieve the same rate output for the cells in the battery pack

Embodiment approach

[0065] As an implementation, the preset condition includes: the product of the first parameter and the second parameter of the energy storage unit in the energy storage component is equal; or, any two energy storage units in the energy storage component The difference between the product of the first parameter and the second parameter is less than a specific value, which can be a preset threshold, so that the charge and discharge ratios of each energy storage unit in the energy storage component are as consistent as possible, so that the impedance of each energy storage unit tends to In order to balance, avoid the energy storage unit in the energy storage component from over-current (over-rate) and so on. The value of the specific value may be determined according to actual conditions. As an example, the value of the specific value may be associated with the quantity and connection mode of the energy storage units in the quantity of the energy storage components. As another e...

Abstract

The embodiment of the invention discloses an information processing method and electronic device. The method comprises the following steps of: obtaining a first parameter and a second parameter of each energy storage unit in an energy storage module, wherein the first parameter represents the capacity of each energy storage unit, and the second parameter represents the internal resistance of eachenergy storage unit; determining an adjustment parameter for the second parameter at least based on the first parameter and the second parameter, and adjusting the second parameter of each energy storage unit in the energy storage module based on the adjustment parameter.

Description

technical field [0001] The present invention relates to information processing technology, in particular to an information processing method and electronic equipment. Background technique [0002] At present, it is gradually tending to connect batteries of different sizes and capacities in series and parallel to form a battery pack (Pack), and in a battery pack, since the capacity of the batteries may be different, the impedance may also be different, the different battery cells The magnification may also be different, and it is easy to exceed the magnification output, resulting in accelerated decay of the battery pack and reduced service life. However, there is currently no effective solution that can achieve the same rate output for the cells in the battery pack. Contents of the invention [0003] In order to solve the existing technical problems, the embodiments of the present invention provide an information processing method and electronic equipment. [0004] In ord...
