Problems solved by technology

Through the above management method and management system, the present invention solves the need to use various equalization operation means during the operation of the existing battery pack, which instead increases and accumulates the consistency difference between the battery cells in the battery pack, accelerates the failure of the backward battery, and at the same time Accelerate the technical disadvantages of dragging down the entire battery pack

Embodiment Construction

[0044] In the embodiment of the present invention, the inventor noticed that in the process of capacity level attenuation, the internal resistance will rise in most cases. Since the hardware requirements of the internal resistance test are high and the uncertainty is also large, the present invention The invention proposes that it can be replaced by the ratio of the fully discharged capacity after the battery is fully charged to the capacity required to be fully charged again. This capacity ratio is called the battery charge / discharge ratio in the present invention, which requires that the battery not only To achieve identifiable ID and input design and manufacturing parameters such as its own brand, type, capacity, service life, capacity temperature coefficient, self-discharge rate, and record the number of charge and discharge times, it is necessary to continuously learn and update the battery during the entire battery life. The level of capacity decay and the charge / discharg...

Abstract

A method and a system achieve precise management of battery packs not provided with charge and discharge balanced operation units by monitoring and precisely measuring SOC (state of charge) and SOH (state of health) of each monomer battery by means of intelligentized monomer power batteries (provided with intelligent battery modules or chips), and overcome the technical defects that consistency differences among the monomer batteries in each battery pack are increased and accumulated, failure of the backward batteries is accelerated and drag of the whole battery packs is also accelerated due to that fact that various balance operation means are required to be used during operation of the battery packs in the prior art.

Description

technical field [0001] The present invention relates to a battery management method, a battery management system, and an intelligent single power battery module through precise management of a single power battery, and more specifically relates to the precise management of a single power battery to realize the connection of battery packs For example, an electric vehicle or an energy storage system does not need to be equipped with a precise battery management method and battery management system with a charge-discharge equalization unit during operation, as well as an intelligent single power battery module used in the aforementioned battery management method and system. [0002] The smart single power battery module (for example, may be included in a smart battery), the battery management method and the battery management system of the present invention can be applied to new energy vehicles such as electric vehicles, energy storage systems, and charging and discharging station...
