Abstract
Shell fragment and because flexible connecting device of this shell fragment realization battery with overcurrent protection function relates to the battery and connects the field. Can solve certain battery cell in the group battery hidden danger that short circuit or thermal runaway lead to battery cell or whole group battery to be blasted appears. The flexonics fundamentally of battery has solved the battery harmd the battery performance very easily in welding process possibility, is favorable to the change of battery, and the recovery that is favorable to scrapping the group battery is recycled. The shell fragment that has the overcurrent protection function is including drawing forth connection piece (1 -1), elastic connection piece (1 -3) and long and thin bandlet (1 -2), long and thin bandlet is being drawn forth between connection piece and the elastic connection piece. The center and the battery electrodes center of shell fragment correspond in proper order, and a plurality of shell fragment welds with the conducting strip is in the same place to the series connection hangzhou of having realized partial battery is parallelly connected.
Description
Technical field
The utility model relates to battery connection area, is particularly useful for connection and the combination of electrokinetic cell.
Background technology
Power battery pack is all realized by multiple cell serial or parallel connection.The rapid rising of very large short circuit current and temperature can be produced when internal short-circuit and thermal runaway situation appear in a certain battery in battery pack, thus causing battery explosion combustion phenomena, the explosive combustion of single battery also can bring disaster to adjacent battery and produce chain explosion reaction.Current power battery pack is all increase a fuse at power output end, but it can not control the current anomaly of each battery.Current battery pack is all that the method for directly welding conducting strip at battery electrode realizes multiple cell serial or parallel connection, and battery is easy to the charge-discharge performance and the battery life that damage battery in welding process.
Summary of the invention
In order to certain cell solved in battery pack, the utility model occurs that the problem that short circuit or thermal runaway cause cell or whole battery pack to be blasted and battery electrode weld the hidden danger of quality brought, propose the shell fragment with overcurrent protection function and the flexible connecting device realizing battery based on this shell fragment.
Have the shell fragment of overcurrent protection, it comprises draws brace 1-1, flexible connection piece 1-3 and elongated bandlet 1-2; Elongated bandlet 1-2 is arranged on and draws between brace 1-1 and flexible connection piece 1-3; Described extraction brace 1-1, flexible connection piece 1-3 and elongated bandlet 1-2 are structure as a whole, and are conductive sheet metal.
The sectional area of described elongated bandlet 1-2 is determined by the size of the Limited Current of battery to be connected and the melting temperature of conductive plate.
Realize the flexible connecting device of battery based on this shell fragment, it also comprises screw 2, pressing plate 3, conducting strip 4, skeleton 5 and battery 6.Described skeleton 2 has several holes, can self-contained battery 6 in hole, and conducting strip 4 is made up of conductive sheet metal, and welds together with several shell fragments 1, and the center of shell fragment and the electrode centers of battery 6 are corresponding in turn to; Pressing plate 4 is made up of insulating material, is fixed on skeleton 5 by screw 2, compresses the shell fragment 1 with battery 6 electrode contact simultaneously.
The shell fragment with overcurrent protection described in the utility model; adopt conductive plate machine-shaping; when there is internal short-circuit or current anomaly in battery; elongated bandlet 1-2 in the middle of shell fragment exceedes the ability to bear of conductor due to current density; produce high temperature and fuse; in time fail battery is rejected from battery pack, eliminate and inhibit abnormal current and temperature rise, thus effectively prevent the possibility of battery explosion burning.
The utility model also has that structure is simple, with low cost, dependable performance and advantage easy for installation.Certain cell that the utility model solves in battery pack occurs that the problem that short circuit or thermal runaway cause cell or whole battery pack to be blasted and battery electrode weld the hidden danger of quality brought, flexibly connect and fundamentally solve the possibility that battery is easy to damage battery performance in welding process, be conducive to the replacing of battery, be conducive to the recycling of waste battery group.
