Embodiment Construction

[0026] figure 1 The structure diagram of the new power battery health management system provided by the embodiment of the present invention. The embodiments of the present invention aim at the large difference in the consistency of different single batteries in the existing power battery health management system, so that some of the single batteries inside the power battery are often in the state of overcharge and overdischarge, resulting in a significant reduction in the life of the power battery. It is easy to spontaneously ignite, resulting in short battery life and low safety of power batteries. A new power battery health management system is proposed, such as figure 1 As shown, the novel power battery health management system 10 includes a power battery 11 , a data acquisition module 12 , a data management module 13 and a balance control module 14 . Wherein, the data acquisition module 12 is used for collecting the current electrical parameters of the power battery in re...

Abstract

An embodiment of the invention provides a novel power battery heath management system. The novel power battery heath management system comprises a power battery, a data acquisition module, a data management module and an equalization control module, wherein the data acquisition module is used for collecting the current electric parameters of the power battery in real time and the sending the current electric parameters to the data management module; the data management module is used for determining index data according to the current electric parameters, generating an instruction signal according to the index data, and sending the instruction signal to the equalization control module; and the equalization control module is used for carrying out equalization control on the power battery according to the instruction signal. According to the embodiment of the invention, the equalization control of the power battery is carried out according to the current electric parameters collected in real time, so that the conditions that the service life of the power battery is shortened or the power battery is subjected to spontaneous combustion caused by the reason that certain single batteries are constantly over-charged or over-discharged due to unbalanced electric quantities among the single batteries are avoided; and consequently, the service life of the battery is prolonged, and the safety of the power battery is improved.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of power electronics, and in particular, to a novel power battery health management system. Background technique [0002] With the country's vigorous promotion of new energy vehicles, electric vehicles have attracted widespread attention due to their "zero emission" advantages. Whether the power batteries of electric vehicles are safe, reliable, durable, and economical has become a hot spot. Health management systems As an important link connecting vehicle-mounted power batteries and electric vehicles, it has become a research hotspot for experts in this field. [0003] Due to many reasons such as production industry, raw and auxiliary materials, etc., there are large differences in the consistency of different single cells, so that some single cells inside the power battery are often in an overcharged and over-discharged state, resulting in a significant reduction in the life of the po...
