The utility model provides an intelligent energy management device for a lithium battery, which comprises a rechargeable battery pack. The rechargeable battery pack is connected with a solar panel and a load. The rechargeable battery pack is connected with the solar panel through a first switch and is connected with the load through a second switch. The first and second switches and the rechargeable battery pack are connected with a singlechip control panel. The intelligent energy management device is used for the management and the control of a lithium battery by means of a technically developed singlechip and can reduce the false accept rate. Meanwhile, the intelligent energy management device lightens or even avoids the influence on a battery or a load.
Description
Technical field
The utility model relates to a kind of management devices of lithium battery, particularly a kind of management devices of solar energy lithium battery.
Background technology
The new forms of energy especially application of solar energy are worldwide increasingly extensive, for human society has been created a kind of new energy savings, reduce the life style of polluting.Because the variation of natural conditions, the distribution of solar energy are in time, the space constantly changes, and can not directly be used for electric in most application scenarios, and this just needs battery energy storage, discharges the stable power supply load then.Energy-storage battery comprises lead acid accumulator, lithium battery etc.
With respect to lead-acid battery, lithium battery has different characteristic, and one of them characteristic that need pay close attention to is exactly: lithium battery is when electric weight is not enough, if connect load, then battery terminal voltage can sharply descend, can't normal power supply.In a lot of occasions, need to detect earlier cell voltage, whether decision inserts load then.If the lithium battery electric weight is few, but measuring voltage is found still more than minimum threshold, then can cause the operator to think by mistake and can connect load, but voltage but sharply to descend after inserting load; Behind the disconnecting consumers, it is normal that voltage recovers again.If the operator repeatedly breaks off the access load operation, then possibly impact battery and load, possibly cause expendable damage when serious, influence the life-span or the performance of battery or load.
The utility model content
Have mirror therewith, the problem that the utility model solved is to provide a kind of can respond to human body, and the science garden etc. of using electric energy more.
The technical scheme of the utility model is: a kind of intelligent energy management apparatus that is used for lithium battery; It comprises rechargeable battery set; Rechargeable battery set connects solar panels and load; Rechargeable battery set connects solar panels through first switch, and connects load through second switch, and this first, second switch and rechargeable battery set connect singlechip control panel.
The beneficial effect of the utility model is: utilize the single-chip microcomputer of technology maturation to manage control for lithium battery, can reduce False Rate, the influence that alleviates even avoid battery or load to receive.
Description of drawings
Fig. 1 is the structured flowchart of the utility model.
Fig. 2 is the running reference diagram of a kind of embodiment of the utility model.
Embodiment
As shown in Figure 1, a kind of intelligent energy management apparatus that is used for lithium battery of the utility model, it comprises rechargeable battery set 1; Rechargeable battery set 1 connects solar panels 2 and load 3; It focuses on, and rechargeable battery set 1 connects solar panels 2 through first switch S 1, and connects load 3 through second switch S2; This first, second switch S 1, S2 and rechargeable battery set 1 connect singlechip control panel 4, utilize this singlechip control panel to come charging and discharging is controlled.
As shown in Figure 1, in running,, then send signal closes or break off first switch if singlechip control panel decision beginning or end are charged to rechargeable battery set; If the discharge of decision beginning or complete charge battery pack is then sent signal closes or is broken off second switch.
The key of the utility model is, utilizes the very ripe single-chip microcomputer of technology to come to control discharging and recharging.Single-chip microcomputer has very strong control ability, utilizes singlechip control panel with the function of charger and discharger, during as discharger, and the electric weight erroneous judgement problem that can avoid prior art partly to mention through SCM program.On the one hand,, the battery discharge situation is monitored, can accumulate the electric weight of emitting by counting cell, the battery pack dump energy is estimated, with the follow-up power supply capacity of prediction battery through SCM program.On the other hand, can suitably improve the battery discharge voltage threshold, not reach as yet in battery discharge capacity before the state that really causes the voltage sharp fall, consider that disconnecting consumers connects.The measure of two aspects combines, and can reduce False Rate, the influence that alleviates even avoid battery or load to receive.Discharge and recharge incorporate control and can also more effectively utilize lithium battery and solar energy, reduce the control system cost and reduce size.The characteristic of utilizing single-chip microcomputer to be convenient to programme, the exploitation algorithm, Collaborative Control charging and discharge come compared with independent exploitation charge controller and discharge control, and integrated level is high, controls more effective.
As shown in Figure 2, be the running reference diagram of a kind of embodiment of the utility model.The rechargeable battery set initial condition is changed to discharge condition, detects signals such as primary cell electric current and voltage then at set intervals, judges the current virtual condition of battery, after the condition that satisfies state exchange, just is transformed in the next state and goes.
The implication of each condition is following among Fig. 2.
Condition 1: the rechargeable battery set electric weight is low, less than the discharge lower limit.
Condition 2: the rechargeable battery set electric weight is high, greater than the charging upper limit, need not to fill again.
Condition 3: the rechargeable battery set electric weight is low, can not continue discharge.
Condition 4: the rechargeable battery set electric weight less than, but greater than the discharge lower limit less than the charging upper limit, can fill and can put.
Condition 5: the rechargeable battery set electric weight less than, but greater than the discharge lower limit less than the charging upper limit, can fill and can put.
Condition 6: the rechargeable battery set electric weight is high, greater than the charging upper limit, need not to recharge.
The implication of each state among Fig. 3 is following.
Charging: solar panels are connected charging with rechargeable battery set, but not to load discharge.
Discharge: rechargeable battery set connects load, to its power supply, but does not connect solar panel charging.
Discharge and recharge: rechargeable battery set connects solar panels and load simultaneously, and charging and discharge process carry out simultaneously.
Use the discharge and recharge Collaborative Control of above-mentioned algorithm, can easily charging and discharge process be combined, avoided lithium battery to cause the characteristic of judging by accident easily and the influence that causes, realize fully effectively utilizing of solar energy and battery pack the lithium battery group.
Above-mentioned algorithm and operation logic all can pass through chip microcontroller, and it is not this case inventive point, and those skilled in the art all can expect, and can make any improvement, repeat no more at this, also should not limit the technical scheme of the utility model with this.
