Problems solved by technology

[0010] At present, the research on multi-battery scheduling is still blank in China, and the current international research is not enough in terms of efficiency optimization. The scheduling method is too simple and lacks a theoretical basis. This is mainly due to the following two reasons. First, the battery is not considered. Non-linear characteristics, and the second is that the attributes of the task itself are not fully understood and used

Embodiment Construction

[0030] Embodiments of the present invention are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals designate the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary only for explaining the present invention and should not be construed as limiting the present invention.

[0031] The present invention is aimed at battery scheduling on a multi-battery power supply system, and proposes a battery scheduling algorithm based on battery idle time (Idle Time based Heuristic algorithm, ItbHA), which is a novel algorithm that can significantly improve computing efficiency. High battery efficiency can be obtained with extremely low computational complexity, and the service time of the battery can be significantly extended.

[0032] Such as figure 1 As shown, it is a flowchart of a battery scheduling method accordin...

Abstract

The invention discloses a method and a device for scheduling batteries, wherein the method comprises the following steps of: sorting according to the sizes of currents required by task execution to obtain sorted results S(k), wherein k belongs to a number from 1 to M, and M represents the number of the tasks; sorting according the sizes of task execution times to obtain sorted results R (k), wherein k belongs to a number from 1 to M, and M represents the number of the tasks; and obtaining scheduling matrixes of a plurality of batteries according to the sorted results S (k) and R (k). By a battery scheduling algorithm based on battery spare time, the computation efficiency can be efficiently improved, the higher battery efficiency is obtained by lower computation complexity, the charge loss can be obviously reduced, and the use time of the batteries is prolonged. In addition, the invention has simple operation and wide application potential.

Description

technical field [0001] The invention relates to the technical field of batteries, in particular to a battery scheduling method and device based on idle time for a multi-battery power supply system. Background technique [0002] At present, there are more and more electronic systems driven by multiple batteries or multiple battery cells, especially in the field of mobile devices, such as portable computers, smart phones, etc. Using multiple batteries for power supply can increase the total capacity of the battery power supply, thereby improving the system standby time. Nevertheless, there is still a serious contradiction between the energy consumption demand brought by high-performance computing and the limited battery capacity, especially the efficiency of multi-battery power supply systems on the market is very low, which makes it difficult to improve the energy utilization of multi-battery power supply systems. Efficiency and prolonging battery life have become one of the...
