Background technology
The effect of battery management system is to control each cell voltage in the battery pack, within the limits prescribed.At present, lead-acid battery in process in groups, charged pool management system not, this is that fail safe is good because the lead-acid battery volumetric specific energy is low.Comparatively speaking, the gravimetric specific energy of lithium battery (that is: the energy of being stored on the Unit Weight) is more than 3 times of lead-acid battery.Simultaneously, because the deviation of voltage can produce and overcharge and the overdischarge problem, can bring potential safety hazard.This just requires the lithium battery assembly to control the battery management system of voltage range fully.
Though the composition structure of lead-acid battery is simpler than lithium battery, lead-acid battery is compared under equal conditions with lithium battery, and weight is 3 times of lithium battery, and volume is 2 times of lithium battery, causes in the use the heavy problem appearance such as carrying that is difficult for.Have certain environmental pollution in the manufacture process of lead-acid battery simultaneously, the lithium battery feature of environmental protection more can be fit to the current social development requirement.
Yet the lithium ion battery group is single 24V/36V/48V battery module on the market at present, and can not simply connect between the lithium battery pack module, owing to there is not basic (or standard) lithium battery 12V battery module, this has just formed the lithium battery motor-car of different capacity, need the different 24V/36V/48V battery module of design, cause the design cost height, versatility/substituting not strong problem is brought inconvenience.
Summary of the invention
The purpose of this utility model is not have basic module at existing lithium-ion battery systems; electric motor car for different capacity; need the different protective circuit of design; single design cost height; versatility and substituting not strong problem in the practical application propose a kind of novel lithium battery management system simple in structure, that be suitable for flexibly.
The technical solution of the utility model is:
A kind of novel lithium battery management system, it comprises at least one general administration module, each general administration module is equipped with an input terminal and a lead-out terminal, connect by input, lead-out terminal between described each general administration module, promptly the first general administration module links to each other with the input terminal of the second general administration module by corresponding lead-out terminal, the lead-out terminal of the second general administration module links to each other with the input terminal of the 3rd general administration module, circulation serial connection successively, the lead-out terminal of the general administration module of N links to each other with the input terminal of the first general administration module; Wherein, arbitrary general administration module is provided with charging light current switch and discharge light current switch, and the two ends of charging light current switch and discharge light current switch link to each other with discharge light current on-off controller with each self-corresponding lithium battery charger respectively.
Each general administration module of the present utility model all is connected with some joint lithium batteries, is equipped with a Temperature Detector corresponding to each lithium battery place, and the signal output part of each Temperature Detector all links to each other with the respective signal input of general administration module.
Temperature Detector of the present utility model is probe.
The beneficial effects of the utility model:
Novel lithium battery management system of the present utility model at the electric motor car of different electrical voltage systems, only needs to adopt " the general administration module " of respective amount input, lead-out terminal simply to be composed in series, and can be connected in series the module of respective numbers for different occasions.The cell number that each general administration module connected also can be according to actual needs and stability requirement, freely selects, and is convenient, flexible, applicability is high.
The utility model in use can utilize built-in charge and discharge light current switch to replace the scheme that traditional lithium electric management system adopts the forceful electric power switch, not only reduced the overall power of management system, and improved the reliability of management system greatly, high-power applications occasion particularly, good stability, reliability height.
