Abstract
The invention relates to a method and equipment for fast and equalizing charging of a lithium ion battery pack. The equipment comprises a single-chip microcomputer controller (C), a sampling circuit (A), a high-power charging source (W), equalizing charging sources (P1-Pn) and a batteries (B1-Bn). Large-current charging is firstly carried out on the battery pack through the high-power charging source, the time that all battery cells reach a fully-charged state is greatly shortened, small-current equalizing charging is carried out on each battery through the equalizing charging sources in a later period, and the consistency of the battery cells in the battery pack is guaranteed.
Description
Technical field
The present invention relates to lithium ion battery group fast uniform charging method and equipment, belong to battery detecting field.
Background technology
General lithium ion battery charger cannot carry out equalizing charge to the battery in battery pack at present, in the course of time, cause the consistency of battery in battery pack to decline, the performance of battery pack is had a strong impact on, and some battery pack balancing charger, because charging current is less, complete the chronic of an equalizing charge, in production and practical link, all cannot accept, the present invention proposes a kind of lithium ion battery group fast uniform charging method and equipment, can either realize quick charge, improve charge efficiency, can carry out equalizing charge to the cell in battery pack again, guarantee the consistency of battery in battery pack.
Summary of the invention
The present invention is intended to propose a kind of lithium ion battery group fast uniform charging method and equipment, and the mode combining by quick charge and equalizing charge, charges to lithium ion battery group, and the whole charging interval is greatly reduced, and battery balanced consistency is better.
For realizing above-mentioned object, the present invention adopts following technical scheme:
Lithium ion battery group fast uniform charging method and equipment, comprise: singlechip controller (C), sample circuit (A), high-power charge power supply (W), equalizing charge power supply (P1～Pn), battery (B1～Bn), see shown in accompanying drawing 1;
With reference to the accompanying drawings, the course of work of the present invention is described:
Battery B1～battery Bn forms battery pack through the mode of series connection, the output of high-power charge power supply (W) is connected to the negative pole of the Anode and battery Bn of battery B1, the output of equalizing charge power supply P1～equalizing charge power supply Pn is connected to respectively positive pole and the negative pole of battery B1～battery Bn accordingly, sample circuit (A) gathers the real-time voltage of battery B1～battery Bn, and passed to singlechip controller (C), singlechip controller (C) is controlled high-power charge power supply (W) and equalizing charge power supply (P1～Pn), by high-power charge power supply (W), battery pack is carried out large current charge or by equalizing charge power supply (P1～Pn), every battery carried out to little current balance charging.
During work, first by high-power charge power supply to battery pack large current charge, the time that makes whole cells reach full state shortens greatly, and the later stage is used equalizing charge power supply to carry out little current balance charging to every battery, guarantees the consistency of cell in battery pack.
The invention has the beneficial effects as follows:
1. quick charge, first by high-power charge power supply fast to batteries charging, the whole charging interval is shortened greatly;
2. battery balanced, the later stage is used equalizing charge power supply to carry out little current balance charging to every battery, guarantees the consistency of cell in battery pack.
accompanying drawing explanation:
Fig. 1 is structural representation of the present invention.
embodiment:
In order to make technical scheme of the present invention clearer, below in conjunction with drawings and Examples, the present invention is described in more detail, and instantiation described herein only, in order to explain the present invention, is not limited to the present invention.
embodiment:
1) battery B1～battery Bn forms battery pack through the mode of series connection;
2) output of high-power charge power supply (W) is connected to the negative pole of the Anode and battery Bn of battery B1, and the output of equalizing charge power supply P1～equalizing charge power supply Pn is connected to respectively positive pole and the negative pole of battery B1～battery Bn accordingly;
3) singlechip controller (C) is controlled high-power charge power supply (W) battery pack is carried out to large current charge;
4) real-time voltage of sample circuit (A) collection battery B1～battery Bn passes to singlechip controller (C), when in battery B1～battery Bn, any cell voltage arrives the upper voltage limit of setting, singlechip controller (C) is controlled high-power charge power supply (W) and is quit work;
5) singlechip controller (C) control equalizing charge power supply (P1～Pn) carries out little current balance charging to every battery;
6) real-time voltage of sample circuit (A) collection battery B1～battery Bn passes to singlechip controller (C), when in battery B1～battery Bn, all batteries voltage all reaches full state, singlechip controller (C) is controlled equalizing charge power supply (P1～Pn) and is quit work, and charging completes.
Claims (1)
1. lithium ion battery group fast uniform charging method and equipment, comprise: singlechip controller (C), sample circuit (A), high-power charge power supply (W), equalizing charge power supply (P1～Pn), battery (B1～Bn), it is characterized in that: battery B1～battery Bn forms battery pack through the mode of series connection, the output of high-power charge power supply (W) is connected to the negative pole of the Anode and battery Bn of battery B1, the output of equalizing charge power supply P1～equalizing charge power supply Pn is connected to respectively positive pole and the negative pole of battery B1～battery Bn accordingly, sample circuit (A) gathers the real-time voltage of battery B1～battery Bn, and passed to singlechip controller (C), singlechip controller (C) is controlled high-power charge power supply (W) and equalizing charge power supply (P1～Pn), by high-power charge power supply (W), battery pack is carried out large current charge or by equalizing charge power supply (P1～Pn), every battery carried out to little current balance charging.
