Abstract

The invention provides a system and a method for self-isolating an abnormal battery. The system comprises a switch control module, a battery detection module, a data analysis module and at least two switch battery modules, wherein each switch battery module comprises an isolating switch, a main loop switch and a battery; each main loop switch is connected with the corresponding battery in series; each isolating switch is connected with a series line which comprises the corresponding main loop switch and battery in parallel to form one switch battery module; the switch battery modules are connected with one another in series; the battery detection module is connected with the batteries and the data analysis module respectively; and the switch control module is connected with the main loop switches, the isolating switches and the data analysis module respectively. The problem that a whole traditional battery pack cannot further work and can only be maintained or recycled due to the problems in the aspects of the lifetime time and the like of one battery is solved.

Description

technical field [0001] The invention relates to the technical field of secondary batteries, in particular to a system and method for self-isolating abnormal batteries. Background technique [0002] Lithium-ion battery is a secondary battery (rechargeable battery) that mainly relies on the movement of lithium ions between the positive and negative electrodes to work. During the charging and discharging process, Li + Intercalation and deintercalation back and forth between two electrodes: when charged, Li + It is deintercalated from the positive electrode, inserted into the negative electrode through the electrolyte, and the negative electrode is in a lithium-rich state; the opposite is true during discharge. Batteries generally use materials containing lithium elements as electrodes, which are representatives of modern high-performance batteries. Since the commercialization of lithium-ion batteries, due to its advantages of high energy density, high voltage, low self-disch...
