Problems solved by technology

[0002] With the rapid development of my country's railways, to ensure the normal operation of high-speed railway communication system equipment, the reliability of batteries in the backup power supply of high-speed railway communication equipment is getting higher and higher. Most of the traditional railway communication equipment batteries use valve-regulated lead-acid batteries, which occupy an area Disadvantages such as large area, high working environment temperature requirements, poor high-rate discharge performance, and environmental pollution are gradually replaced by lithium iron phosphate batteries with high energy density, small size, light weight, long cycle life, and pollution-free
[0003] Most of the existing lithium iron phosphate battery packs are used in conjunction with the high-frequency switching power supply in the communication room. At present, there is no lithium iron phosphate battery pack used in tunnel repeaters with harsh working environments.

Embodiment Construction

[0022] The present invention will be further described below in conjunction with accompanying drawing.

[0023] The invention consists of N (N is a natural number) 3.2V100Ah lithium iron phosphate battery, a single battery monitoring module, a current monitoring module, a control module and a convergence module (see figure 1 ). "Single cell monitoring module" is responsible for collecting cell voltage and cell pole temperature, and has balance function and balance failure protection function. It has a high-precision 24-bit AD acquisition chip; the current detection module cooperates with the Hall sensor to detect current. All the signals collected or detected by the "single cell monitoring module" and "current detection module" are uploaded to the "convergence module", which is responsible for data analysis, storage, and calculation of SOC and SOH, with local alarm function , the "convergence module" has multi-level alarm settings. If there is a non-serious alarm, the local a...

Abstract

The invention provides a distributed management lithium iron phosphate battery pack. The distributed management lithium iron phosphate battery pack comprises N lithium iron phosphate batteries connected in series, single battery monitoring modules, a current monitoring module, a control module and a convergence module, wherein N is a natural number; each lithium iron phosphate battery is providedwith an independent single battery monitoring module; each single battery monitoring module collects the voltage of each single battery and the temperature of a single pole; the plurality of single battery monitoring modules are connected in series and then connected with the convergence module and upload all collected or detected signals to the convergence module; the current detection module ismatched with the Hall sensor so as to be connected with the convergence module, and uploads all collected or detected signals to the convergence module; the convergence module analyzes and stores thecollected data and calculates an SOC and an SOH; and the convergence module is connected with the single battery monitoring modules by adopting a distributed BMS (Battery Management System) to discontinuously supply power for 12 hours. A distributed BMS management system is built in the distributed management lithium iron phosphate battery pack and is used for monitoring and managing the battery pack in real time.
