Abstract
Disclosed is a sub-capacity cabinet current recycling system including a sub-capacity cabinet, a combiner box, a voltage regulator, a charger and a storage battery. The sub-capacity cabinet current recycling system is characterized in that the sub-capacity cabinet is connected to an input end of the combiner box via a wire on which a diode is disposed; an output end of the combiner box is electrically connected to an input end of the voltage regulator, and a low-frequency choking coil is disposed between the combiner box and the voltage regulator; and the voltage regulator, the charger and the storage battery are electrically connected, the storage battery can provide power back for the sub-capacity cabinet after obtaining a current, and thus the test cost is effectively reduced and power recycling is achieved.
Description
Technical field
The utility model relates to a kind of electric current recovery system, relates in particular to a kind of electric current recovery system that grading system runs off in lithium ion battery charge and discharge process.
Background technology
In recent years, lithium ion battery is used widely in every field such as electronic products with premium properties such as its high-energy-density, high voltage, high circulation, high security, environmental protections.
After lithium ion battery completes, for quality and performance the transmission path of further dredging Li+ between both positive and negative polarity of checking product battery, improve the cycle performance in the use procedure of battery later stage, guarantee the security performance of product after dispatching from the factory, before shipment, need lithium ion battery to discharge and recharge several times, this operation is called " partial volume ".
The partial volume of lithium ion battery is realized by grading system at present, when battery charging, by external power source, puts position charging by grading system; When battery discharge, be by grading system self, power consumption to be fallen.The electric energy that grading system consuming cells discharges is heating after the resistance energising by carrying, be that heat energy discharges by electric energy conversion, just think, every day, the electric energy of hundreds thousand of W*h that several ten thousand batteries are emitted was consumed like this, it is great energy waste, along with popularizing of lithium ion battery, this waste will constantly increase, in addition, the heat discharging directly affects partial volume workshop room temperature, make it higher than normal temperature, indirectly can affect the accuracy of lithium battery capacity test data, cause very big interference for whether judgement product is qualified.
Summary of the invention
For addressing the above problem, the utility model provides a kind of grading system electric current recovery system, this system has fully reclaimed the electric current running off in vain in charging and discharging lithium battery process, thoroughly having stopped electric energy conversion by the recovery of electric current is that heat energy causes workshop temperature higher, thus the not high problem of accuracy when remote-effects battery capacity is tested.
For achieving the above object, the utility model is by the following technical solutions: a kind of grading system electric current recovery system, comprise grading system, header box, pressurizer, charger and energy-storage battery, the electric discharge port of described grading system is connected with the input of return tank by wire, on its wire, is provided with diode; The output of described header box is electrically connected with the input of pressurizer, between header box and pressurizer, is provided with low-frequency choke coil; Between described pressurizer, charger and energy-storage battery, be electrically connected.
The beneficial effects of the utility model are: the electrical power storage of 1, lithium ion battery being emitted in partial volume operation, realize recycling of electric energy, and improve energy utilization rate; Lower energy consumption, reduce production costs; Eliminate the factor of partial volume workshop temperature higher than room temperature, improve the accuracy of battery partial volume volume test, improve product turnout qualification rate; 2, effectively prevent the electric current reverse-conducting of output by diode is set between grading system and header box, thereby make energy equilibrium mutually between battery; 3, by the disappearance that low-frequency choke coil has effectively postponed electric current is set between header box and pressurizer, and stop passing through of alternating current.
Brief description of the drawings
Be described further below in conjunction with the drawings and specific embodiments the utility model.
A kind of grading system electric current of Fig. 1 recovery system.
Embodiment
As shown in Figure 1, a kind of grading system electric current recovery system, comprise grading system, header box, pressurizer, charger and energy-storage battery, it is characterized in that the electric discharge port of described grading system is connected with the input of return tank by wire, on its wire, be provided with diode; The output of described header box is electrically connected with the input of pressurizer, between header box and pressurizer, is provided with low-frequency choke coil; Between described pressurizer, charger and energy-storage battery, be electrically connected.
The utility model is work like this: grading system is in charge and discharge process, electric current converges to electric discharge port, electric current on electric discharge port is the current input terminal to header box by wire transmission, on wire, be provided with diode, the effect of diode is to prevent electric current reverse-conducting, header box carries out delay disposal by choke to the electric current obtaining after obtaining electric power, then be transferred to pressurizer, pressurizer carries out after calm disposing electric current, by current delivery, to charger, then charger is stored in electric current in energy-storage battery.
Energy-storage battery can oppositely provide electric power to grading system after obtaining electric current, thereby effectively reduces testing cost, realizes power cycle and uses.
Apparent above-mentioned execution mode is only preferred embodiments of the present utility model, and any simple modifications on this basis all belongs to protection range of the present utility model.
