The management method comprises the following of: a) testing capacity values of the battery at different temperatures, and storing the values into the battery management system; b) collecting the environmental temperature of the backup battery through the battery management system, and finding the corresponding capacity value according to the environmental temperature; and c) adjusting the capacity value in real time into the threshold value of controlling the battery charging and discharging. The management circuit and the management method have the advantages that: 1, according to rectify the threshold value by the battery management system, the battery is ensured not to be overcharged or over-discharged, and the service life of the battery is prolonged; and 2, the temperature scope in use of the battery is relatively broadened.
Description
Technical field
The present invention relates to the management of mobile communication base station backup battery.
Background technology
Threshold parameter such as present battery management system high temperature, low temperature, SOC are all fixed; When the environment for use temperature contrast is big, (reach more than 50 ℃ like desert maximum temperature in summer; And European winter minimum temperature reaches below 30 ℃); Variation has all taken place in parameters such as the capacity of battery, internal resistance, ceiling voltage, and this just possibly cause battery system to overcharge or cross problem such as put.
Summary of the invention
In view of this, one of the present invention's technical problem that will solve provides a kind of mobile communication base station backup battery management circuit that can in time adjust the battery charging and discharging threshold value.
In order to solve the problems of the technologies described above, this technical problem adopts following scheme to solve:
A kind of mobile communication base station backup battery management circuit is connected in the battery charging and discharging circuit, comprises the temperature inductor of battery management system and testing environment temperature, and battery management system is through the threshold value that discharges and recharges of testing environment temperature real time modifying battery.
Another technical problem that the present invention will solve provides a kind of mobile communication base station backup battery management method, and the threshold value of battery management system can change with environmental change in this method, prevents over-charging of battery and cross to put.
This management method comprises as follows:
A). test in advance is the capability value of this battery at each temperature, and deposits in the battery management system;
B). battery management system is gathered the backup battery ambient temperature, finds out the capacity corresponding value according to this ambient temperature;
C). battery management system is adjusted into this capability value the threshold value of control battery charging and discharging in real time.
Compared with prior art, the present invention has following advantage:
1. battery management system is through revising in real time threshold values, guarantees that battery can not overcharge or cross to put, and prolonged battery useful life.
2. enlarged the serviceability temperature scope of battery relatively; Because this battery management system adopts intelligence to revise the control strategy of temperature parameter; The battery management system of this programme is more superior in the serviceability in peak temperature district than present battery management system, and the temperature range of use is wideer.
Description of drawings
Fig. 1 is the ferric phosphate lithium cell temperature characteristics that performance is comparatively superior on certain market.
Fig. 2 is an embodiment of the invention circuit diagram.
Embodiment
Below will combine accompanying drawing and embodiment that the present invention is described in further detail for the ease of it will be appreciated by those skilled in the art that:
Because of mobile communication base station often is used in the Gobi desert of remote rural area, the length and breadth of land, the dense rugged environments such as mountain forest; These regional national grids are difficult to set up; Therefore mobile communication base station need be equipped with backup battery, and the electric energy of battery is provided by photo-voltaic power generation station or wind energy power plant usually.Because that battery uses is big in the temperature difference, in the environment such as peak temperature is higher, charge power supply instability, so the present ferric phosphate lithium cell that only has excellent properties such as energy density height, high safety, high-temperature behavior are good, high power output, long circulation life, environmental protection is only the optimal selection of mobile communication base station back-up source.Though the ferric phosphate lithium cell high-temperature behavior is good, the not talkative influence that does not receive high low temperature, and also it receives the influence of low temperature also bigger.
Accompanying drawing 1 is the ferric phosphate lithium cell temperature characteristics that performance is comparatively superior on certain market.Can find that from this figure ferric phosphate lithium cell discharge capacity 23 ℃ the time is 100%, discharge capacity is 78% in the time of 0 ℃, and discharge capacity is below 40% and decay rapidly in the time of-40 ℃, and discharge capacity is slightly larger than 100% in the time of+40 ℃.
The embodiment of the invention is passed through in the different temperatures curve battery capacity value typing battery management system corresponding under the above-mentioned different temperatures; Battery management system is according to the variation of ambient temperature; Select the different temperature curve values; In real time to the real-time correction of threshold values, guarantee that battery system can not overcharge or cross to put under any temperature environment, thereby reach the protection battery system, prolong the battery purpose in useful life.
Particularly, for another example shown in the accompanying drawing 2.The mobile communication base station backup battery management circuit that present embodiment discloses is connected in the battery charging and discharging circuit; The temperature inductor that comprises battery management system 1 and testing environment temperature, battery management system 1 is through the threshold value that discharges and recharges of testing environment temperature real time modifying battery.
Simultaneously, this programme has disclosed a kind of mobile communication base station backup battery management method, and this management method comprises:
A). test in advance is the capability value of this battery at each temperature, and deposits in the battery management system;
B). battery management system is gathered the backup battery ambient temperature, finds out the capacity corresponding value according to this ambient temperature;
C). battery management system is adjusted into this capability value the threshold value of control battery charging and discharging in real time.
The foregoing description is merely wherein concrete implementation of the present invention, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to claim of the present invention.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the present invention's design, can also make some distortion and improvement, these conspicuous replacement forms all belong to protection scope of the present invention.
