Abstract
A current-limiting electric-conductive sheet having overcurrent protection and an apparatus based on same for quick connection between batteries. The invention relates to the field of battery connection and solves a problem of explosion on single cell or a whole battery set due to short circuit or thermal runaway in any one single cell in the battery set. The current-limiting electric-conductive sheet having overcurrent protection includes: a first connection sheet, a second connection sheet and a long-and-thin flat band arranged therebetween. The first connection sheet and the second connection sheet are disposed in parallel. The first connection sheet, the second connection sheet and the long-and-thin flat band are integrated and are all formed from electric-conductive thin plates. The apparatus based on the current-limiting electric-conductive sheet for quick connection between batteries includes a magnet being fixed between the first connection sheet and the second connection sheet of the current-limiting electric-conductive sheet and is adhered to the first connection sheet. The electric-conductive sheet is also suitable for batteries or battery sets in other types.
Description
Technical field
The present invention relates to battery connection area.
Background technology
Battery pack realizes by multiple cell serial or parallel connections. When internal short-circuit appears in a certain battery in battery packDuring with thermal runaway situation, can produce the rapid rising of very large short circuit current and temperature, thereby cause the battery combustion phenomena of blasting,The explosive combustion of single battery also can bring disaster to adjacent battery and produce chain explosion reaction. Current battery pack is all to export at power supplyEnd increases a fuse, but it can not control the current anomaly of each battery, particularly for thousands of baby batteriesThe battery pack of composition, does not also have a kind of dependable performance at present, and the list of simple and feasible props up battery overcurrent protection structure.
Summary of the invention
The present invention occurs that short circuit or thermal runaway cause cell or whole battery pack for certain cell solving in battery packThe problem of blasting, has proposed to have the current limliting conducting strip of overcurrent protection and has realized connecting fast of battery based on this current limliting conducting stripConnection device.
Have the current limliting conducting strip of overcurrent protection, it comprises brace 1-1, No. two brace 1-3 and elongated bandlet 1-2;Elongated bandlet 1-2 is arranged between a brace 1-1 and No. two brace 1-3; A described brace 1-1 is connected with No. twoThe parallel placement of sheet 1-3; A described brace 1-1, No. two brace 1-3 and elongated bandlet 1-2 are structure as a whole, and areConductive plate.
The sectional area of described elongated bandlet 1-2 is by the size of the Limited Current of battery to be connected and the melting temperature of conductive plateDetermine.
The Quick Connect Kit of realizing battery based on this current limliting conducting strip, it comprises magnet 2, described magnet 2 is fixed on has overcurrentBetween a brace 1-1 and No. two brace 1-3 of the current limliting conducting strip of protection, and be close to brace 1-1 No. one.
The current limliting conducting strip with overcurrent protection of the present invention, adopts conductive plate machine-shaping, and two ends are all splicing ears,Centre is an elongated bandlet. One of them splicing ear of current limliting conducting strip is connected with battery; Another splicing ear connects anotherBattery or the sheet that confluxes are connected. In the time there is internal short-circuit or current anomaly in battery, elongated flat in the middle of current limliting conducting stripBe with the ability to bear that exceedes conductor due to current density, produce high temperature and fusing, in time fail battery is rejected from battery pack,Eliminate and suppressed abnormal current and temperature rise, thus effectively prevented battery blast burning possibility.
The Quick Connect Kit of realizing battery based on this current limliting conducting strip of the present invention, adopts in current limliting conducting strip and battery phaseThe mode of below the splicing ear connecting, a magnet being installed. In the time that battery steel shell approaches current limliting conducting strip, the magnetic below splicing earIron and battery steel shell form the closed loop magnetic line of force, make current limliting conducting strip touch tightly battery steel shell, thereby realize the quick of batteryConnect and flexibly connect.
Simple in structure, with low cost, dependable performance and easy for installation that the present invention also has advantages of. The present invention is also applicable to otherThe battery of type or battery pack.
