Description
Technical field
The utility model relates to a kind of battery gathering line, belongs to battery applications technical field.
Background technology
Along with the fast development of New Energy Industry, lithium ion battery obtains large-scale application.Because lithium ion battery voltage platform is low, adopt series connection burst mode in use.In addition, because the self-characteristic of lithium battery needs, lithium battery group requires that the voltage and temperature to often propping up battery gathers, monitors in real time in use.At present, the method generally adopted in industry is above lithium battery pole, install voltage acquisition line and temperature acquisition line additional, and voltage acquisition line and temperature acquisition line independently design, and adopts cold end terminal to be connected to above battery electrode column separately.Existing acquisition method has certain drawback: first, and voltage acquisition line and temperature acquisition line independently design, and wire harness is mixed and disorderly, intensity is lower, is unfavorable for Integrated predict model; Secondly, voltage acquisition line and temperature acquisition line respectively comprise a cold end terminal, and cost is higher; Finally, voltage acquisition line and cold end terminal are directly electrically connected, and can not depart from after occurring, have certain potential safety hazard during level short circuit with electric battery.
Utility model content
The purpose of this utility model is to provide a kind of battery gathering line, and to solve, the wire harness that existing battery gathering line causes because of voltage acquisition and temperature acquisition separate design is mixed and disorderly, wire harness intensity is low, high in cost of production problem.
The utility model is for solving the problems of the technologies described above and providing a kind of battery gathering line, comprise temperature acquisition line and voltage acquisition line, one end of described voltage acquisition line is welded in cold end terminal, this cold end terminal internal fixtion has the temperature sensor be connected with temperature acquisition line, this cold end terminal, for connecting the pole of battery, realizes the collection to cell voltage and temperature.
Described battery gathering line is serially connected with protective tube near cold end terminal side, to realize the short-circuit protection to battery gathering line.
Described temperature sensor is NTC sensor.
Described NTC sensor is potted in cold end terminal by special gelatin.
Described voltage acquisition line and battery gathering line sticky with together with.
The beneficial effects of the utility model are: the utility model battery gathering line comprises temperature acquisition line and voltage acquisition line, wherein one end of voltage acquisition line is welded in cold end terminal, this cold end terminal internal fixtion has the temperature sensor be connected with temperature acquisition line, this cold end terminal, for connecting the pole of battery, realizes the collection to cell voltage and temperature.Battery gathering line integrated level of the present utility model is high, achieves voltage acquisition and temperature acquisition two kinds of functions simultaneously, the safety and reliability that improve wire harness intensity, simplify harness wiring workload, reduce battery acquisition cost, improve battery collection.
Accompanying drawing explanation

Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further,
The embodiment one of battery gathering line of the present utility model
Battery gathering line of the present utility model as shown in Figure 1, comprise temperature acquisition line and voltage acquisition line, voltage acquisition line and temperature acquisition line by glue sticky with together with, one end of voltage acquisition line is welded in cold end terminal 1, this cold end terminal 1 internal fixtion has the temperature sensor be connected with temperature acquisition line, and temperature sensor is potted in cold end terminal by special gelatin.Here the reasonable glue of thermal conductivity selected by special gelatin, and temperature sensor adopts NTC sensor.During use, cold end terminal is connected on the pole of battery, voltage acquisition line realizes the collection to cell voltage by cold end terminal, cold end terminal is connected on pole can the temperature variation of perception pole, and the NTC sensor by heat trnasfer the temperature variation of pole is delivered in cold end terminal, realize the temperature acquisition of NTC sensor to battery.
The electric battery be connected into for six lithium batteries is below described, for this electric battery, need seven battery gathering lines (battery gathers #1 ~ battery and gathers #7) altogether, the cold end terminal of seven battery gathering lines connects the positive and negative terminals of each battery in electric battery, one end connects the collection port of battery management system BMS in addition, can realize voltage acquisition and the temperature acquisition of six cells, concrete connection as shown in Figure 3 simultaneously.
The embodiment two of battery gathering line of the present utility model
The present embodiment is the further improvement on embodiment one basis; by realizing short-circuit protection at voltage acquisition line near cold end terminal side serial connection protective tube; as shown in Figure 2; this battery gathering line comprises temperature acquisition line and voltage acquisition line; one end of voltage acquisition line is welded in cold end terminal; voltage acquisition line near cold end terminal side is serially connected with protective tube FUSE; this cold end terminal internal fixtion has the temperature sensor be connected with temperature acquisition line, and temperature sensor is potted in cold end terminal by special gelatin.Its concrete principle of work was illustrated in last embodiment, repeated no more here.
Battery gathering line integrated level of the present utility model is high, achieve voltage acquisition and temperature acquisition two kinds of functions simultaneously, it is advantageous that the safety and reliability improving wire harness intensity, simplify harness wiring workload, reduce battery acquisition cost, improve battery collection.This mentality of designing is novel, solves the difficult problem that current industry faces, has wide popularizing application prospect.
