Problems solved by technology

[0006] 1. The change of the total voltage of the battery pack has a large deviation in the effectiveness of mapping battery strings or battery-related characteristics on the string, and the deviation is positively related to the difference in battery power between the battery strings and the number of battery packs
[0007] 2. For battery packs with many series and large differences in battery power, some batteries on the battery string with low power are prone to overdischarge and overcharge, which will accelerate the power decay of these batteries
[0008] 3. The part of the battery pack that is higher than the minimum string power value of the other strings whose power is higher than this value cannot be used, resulting in waste of resources
[0009] 4. The fixed combination management system cannot obtain the power decay or damage information of the battery pack, and it is extremely difficult to check and replace
[0010] 5. The attenuation or damage of some batteries will cause a large drop in the power of the battery pack, and sometimes even the entire battery needs to be replaced
[0011] 6. Due to cycle attenuation and temperature attenuation, the difference in production capacity of the battery pack cannot be responded to in a timely manner.

Abstract

The invention provides an intelligent management system for a variable combined battery pack. The intelligent management system comprises a variable battery pack module, a switch detection module, an electric control switch module, an AD detection module, an electric appliance module, a signal acquisition module, a man-machine interaction module and a control center module. The method comprises the following steps of: detecting and calculating string group electric quantity difference in a use process of a battery pack and under standard power utilization, and judging that the electric quantity of the battery pack is necessary to be detected by combining the number of over-discharge batteries obtained by low-electric-quantity power utilization detection of the battery pack, closing an over-discharge battery connection switch and string group distribution or time interval or cycle index interval; the data is provided for a user, so that the user determines whether to start electric quantity detection of the battery; after the system is charged, the electric quantity is detected; the system calculates a reassembled battery pack according to the detected electric quantity of each battery, so that the electric quantity of each string group is similar; and through the electric control switch module and updating a switch distribution column in the battery information table after recombination, a switch of the battery connection string group is turned on, and the target of intelligent battery pack recombination is achieved.

Description

Technical field [0001] The present invention involves the field of battery pack design technology. Specifically, it involves an intelligent management system for variable combination battery packs. Background technique [0002] At present, the battery combination mostly uses a fixed group, that is, each battery is fixed to a string group in the battery pack. Because the battery pack battery is mostly lithium batteries and lead batteries, these batteries have strong personality characteristics. Even the same specifications produced by the same manufacturer of the same manufacturer, the battery quality is slightly different. The amount of electricity attenuation in production such as cycles, time, and temperature changes is uneven. [0003] The personality characteristics of the battery will be transmitted to the battery packs composed of it, so that the actual electricity of each series of the battery packs will cause the battery pack to difference. Different sizes are related to ...
