Description
Technical field
The utility model relates to ferric phosphate lithium cell, relates in particular to a kind of ferric phosphate lithium cell privacy protection plate.
Background technology
Ferric phosphate lithium cell is at present as a kind of novel environment friendly, and is efficient, the electrokinetic cell that moment can heavy-current discharge; Its particular performances is accepted by market gradually; Be mainly used in fields such as solar street light, electric tool, automobile at present; Along with applying of solar energy, its particular performances possesses wide prospect in the application of field of solar energy.
The reference voltage of lithium iron phosphate dynamic battery is 3.2V; For satisfying user demand; Must multiple batteries series connection be reached required voltage, and with a collection of electric core after making, their capacity and internal resistance all exist to differ to be led; Therefore before combination, must lead less battery to difference and fit over one group, with the purpose that recycles the life-span of the prolongation battery on acquiring a certain degree.The battery pack of together forming for a plurality of battery strings; Need every batteries of this battery pack is carried out charge and discharge process; Solar street light is owing to require to adopt higher input voltage; Or even moment variable voltage, existing universal battery baffle can not satisfy this battery the applying of field of solar energy, and has hindered its popularization in this field.In order to address this problem, must adopt withstand voltage very high, the electronic device that anti-instantaneous large-current impacts certainly will cause volume big like this, and cost is high, can not be fit to the demand for development of heliotechnics.
Summary of the invention
The utility model provides ferric phosphate lithium cell privacy protection plate; A kind of ferric phosphate lithium cell that can high-voltage charging; Realize that through the privacy protection plate this baffle is realized through software systems, can effectively the charge and discharge of battery pack be monitored in real time and protect; Prevent safety protection functions such as battery pack overcurrent, guarantee that battery pack moves safely and effectively.
To achieve these goals, the technical scheme of the utility model employing is
The utility model structure is: solar panel (1), baffle (2), ferric phosphate lithium cell (3); Solar panel (1) rear end connects baffle (2), and baffle (2) is connected on the ferric phosphate lithium cell (3).
The beneficial effect of the utility model:
Ferric phosphate lithium cell is at present as a kind of novel environment friendly, efficient, the electrokinetic cell that moment can heavy-current discharge, and ferric phosphate lithium cell is connected with baffle; Not only can discharge and recharge by the voltage in 12-24V; Be used on the solar street light, can also under the voltage of 160V, charge to battery and do not damage battery, volume is little; Cost is low, and its particular performances possesses wide prospect in the low application of sending out the district of the especially tangible solar energy of field of solar energy.
Description of drawings:
Fig. 1 is the overall structure figure of the utility model.
Fig. 2 is the circuit diagram of the utility model.
Concrete execution mode:
The utility model structure is: solar panel (1), baffle (2), ferric phosphate lithium cell (3); Solar panel (1) rear end connects baffle (2), and baffle (2) is connected on the ferric phosphate lithium cell (3).
The internal structure of ferric phosphate lithium cell (3) is the positive pole of LiFePO4 as battery; Be connected with anode by aluminium foil; The centre is the barrier film of polymer, and its separates with negative pole anodal, but lithium ion Li+ can through and electronics e-can not pass through; The GND that carbon (graphite) is formed is connected with the negative pole of battery by Copper Foil.Be the electrolyte of battery between the upper and lower side of battery, battery is by the metal shell enclosed package.
The LiFePO4 battery is when charging, and the lithium ion Li+ in the positive pole moves to negative pole through membrane for polymer; In discharge process, the lithium ion Li+ in the negative pole moves to positive pole through barrier film.
Ferric phosphate lithium cell (3) is connected with baffle (2), and protective circuit detects the voltage and current of every battery in the series battery respectively, the charge and discharge process of control battery pack.The voltage of every battery all detects voltage and crosses to put and detect between the voltage overcharging in the battery pack, and during the no short circuit phenomenon of output, the metal-oxide-semiconductor conducting, P+, P-export battery voltage, and the permission battery pack discharges and recharges operation; The voltage of any battery in the series battery dropped to put and detects voltage and reached when putting delay time, crossed to put defencive function and start, and cut off the discharge metal-oxide-semiconductor; Forbid the external output current of battery pack; Protection battery pack safety, circuit board gets into resting state, and the circuit board current sinking is below the quiescent current; The circuit that gets into resting state is only after connecting charger, and cell voltage surpassed and could recover after putting recovery voltage; In to the batteries charging process, when rising to over-charging of battery, any batteries voltage detects voltage, and when overcharging delay time; The over-charge protective function on; Cut off the charging metal-oxide-semiconductor, forbid, protection battery pack safety batteries charging; Drop to and overcharge recovery voltage when following when battery pack connects load discharge or cell voltage, the state of overcharging is resumed; When battery power discharge port P+ and P-were short-circuited, protective circuit can be cut off the discharge metal-oxide-semiconductor behind the short-circuit protection delay time, forbade that battery pack externally discharges, and after external short circuit was removed, circuit recovered automatically; As battery power discharge port P+ with P-overcharges or during the discharging current phenomenon, protective circuit can be cut off the discharge metal-oxide-semiconductor behind the overcurrent protection delay time, forbid that battery pack externally discharges, after external short circuit was removed, circuit recovered automatically.
Solar panel (1) is when giving ferric phosphate lithium cell (3) charging; Because on ferric phosphate lithium cell (3), having connected baffle (2) can effectively monitor the charge and discharge of battery pack and protect in real time; Prevent safety protection functions such as battery pack overcurrent, guarantee that battery pack moves safely and effectively.
According to the announcement and the instruction of above-mentioned specification, the utility model those skilled in the art can also change and revise above-mentioned execution mode.Therefore, the embodiment that discloses and describe above the utility model is not limited to is in the protection range of the claim that also should fall into the utility model to some modifications and the change of the utility model.In addition, although used some specific terms in this specification, these terms are explanation for ease just, the utility model is not constituted any restriction.
