Description
Technical field
The present invention relates to a kind of high-performance power battery group, belong to battery applications field.
Background technology
Along with development and the progress of electric automobile, the demand of electrokinetic cell is also improved constantly, current common battery combination form one is large serial battery pattern, the capacity of every only large battery easily more than hundreds of ampere-hour, the fail safe of battery becomes the important safety factor directly affecting electric automobile, and the design principle problem of large battery, fail safe must be caused bad, another kind of battery combination form is the pattern of connecting again after baby battery parallel connection, because battery self-capacity is very little, general below 3 ampere-hours, the safety ratio of battery itself is better, but because needs hundreds of only composes in parallel a battery pack base unit, number of batteries is very many, because a hundreds of battery of parallel connection can not at voltage, capacity is consistent, difference between battery can cause battery pack overall performance to decline, the present invention proposes to solve above contradiction just.
Summary of the invention
The present invention is intended to propose a kind of high-performance power battery group, by the difference between each cell during solution cell parallel, ensures monomer battery with two side terminals, thus improves the overall performance of power battery pack.

A kind of high-performance power battery group, comprise: monomer battery core module 1 (A1) in parallel ~ monomer battery core module N (An) in parallel, battery control and management unit (B), positive battery terminal (C), negative battery terminal (D); See accompanying drawing 1;
Described monomer battery core module (A1 ~ An) in parallel is by monomer battery core 1 (5-1) ~ monomer battery core N (5-n), communication module (4), positive terminal (1), negative terminal (2), voltage acquisition control module (3) is formed, and sees accompanying drawing 2;
Below with reference to the accompanying drawings 1 and accompanying drawing 2, the course of work of the present invention is described:
Monomer battery core module 1 (A1) ~ monomer battery core module N (An) in parallel in parallel is cascaded, composition power battery pack, the communication unit of monomer battery core module 1 (A1) ~ monomer battery core module N (An) in parallel in parallel is connected with battery control and management unit (B), the positive terminal of monomer battery core module 1 (A1) in parallel is connected to positive battery terminal (C), and the negative pole end of monomer battery core module N (An) in parallel is connected to negative battery terminal (D).
The monomer battery core 1 (5-1) ~ monomer battery core N (5-n) of monomer battery core inside modules in parallel is connected in parallel, and completes voltage acquisition and dynamic conformance balanced management by voltage acquisition control module (3).
Beneficial effect of the present invention:
(1) the individual difference problem between the batteries in parallel connection forming large battery assembly module is solved;
(2) improve the overall performance of power battery pack, thus improve its useful life;
(3) progradation is had for the application promoting electric automobile.
accompanying drawing illustrates:
Fig. 1 is theory diagram of the present invention;
Fig. 2 is monomer battery core inside modules block diagram in parallel in the present invention.
embodiment:
In order to make technical scheme of the present invention clearly understand, below in conjunction with drawings and Examples, the present invention is described in more detail, instantiation described herein, only in order to explain the present invention, is not limited to the present invention.
embodiment:
1, get 64 3 ampere-hour cells and be labeled as (5-1) ~ (5-64), by conducting strip, respectively the positive pole of these batteries is linked together, receive positive terminal (1), again negative pole is linked together, receive negative terminal (2);
2, the insulated conductor of 0.12 square millimeter is drawn from the positive pole of every cell, be connected to voltage acquisition control module (3), draw the insulated conductor of 0.12 square millimeter from negative terminal (2), be connected to voltage acquisition control module (3);
3, communication module (4) is connected with external cell module controls center;
4, repeat step 1-3, complete 100 groups of monomer battery core modules in parallel;
5, the positive terminal of monomer battery core module 1 (A1) in parallel is connected to positive battery terminal (C), the negative pole end of monomer battery core module 1 (A1) in parallel is connected to the positive terminal of monomer battery core module 2 (A2) in parallel, the negative pole end of monomer battery core module 2 (A2) in parallel is connected to the positive terminal of monomer battery core module 3 (A3) in parallel, by that analogy, the negative pole end of monomer battery core module N (An) in parallel is connected to negative battery terminal (D), completes battery pack and connects.
