A kind of soc estimation method, mobile power supply and readable storage medium

Abstract

The invention discloses an SOC estimation method, a mobile power supply and a readable storage medium, mainly by calculating the power value of the mobile power supply with a fixed step size, and then step by step and superimposing the unit power to calculate the cumulative distance from the mobile power supply to the last SOC change time. Electricity, then compare the absolute value of the accumulated electricity with the electricity value of the fixed step size, and based on the comparison result, add / decrease the SOC value by a fixed step size or keep the SOC value unchanged, and obtain the starting value of the accumulated electric quantity at the next moment . By obtaining the SOC value of the mobile power supply in the above way, in actual programming, only if judgment and addition and subtraction operations can be used to replace the division operation of the existing SOC estimation method, which greatly reduces the amount of calculation when estimating SOC and reduces the consumption of computing resources. As well as the occupation of storage space, it greatly reduces the requirements for chip computing power and peripheral resources, reduces equipment energy consumption, improves SOC estimation speed and improves computing stability.

Description

technical field [0001] The present invention relates to the technical field of mobile power SOC estimation, in particular to a SOC estimation method, a mobile power supply and a readable storage medium. Background technique [0002] At present, for portable micro-miniature energy storage products on the market, due to the high cost of electronic products, major manufacturers have also begun to look for lower-cost alternatives. When choosing alternative materials, we usually choose cheap chips with weak computing power or constantly compress chip peripheral resources and performance. However, for micro-miniature mobile power products, it involves many operations, such as SOC (state of charge) estimation, etc., only chips with high performance, strong computing power and fast computing speed can be applied. If you only pursue low-cost chips without simplifying the operation, it will inevitably fail to adapt and be compatible. [0003] In the calculation of the chip, the calc...

Problems solved by technology

[0005] This algorithm uses operations such as addition, subtraction, multiplication, and division, and the calculation cost is huge, and chips with low prices and weak computing capabilities cannot meet its calculation requirements, so a low-cost solution for SOC estimation algorithms is urgently needed
