Embodiment
Be described in more detail below in conjunction with the technical scheme of embodiment to this patent.
Refer to Fig. 1-5, a kind of lithium battery detection device, comprise base 1, on described base 1, corner is provided with column 2, column 2 upper end is provided with installing plate 3, voltage internal resistance test device 4 is installed on the upside of installing plate 3, longitudinally guide rail 5 is provided with in the middle of the downside of installing plate 3, guide rail 5 is connected with the first hydraulic means 6, the front end that the rear end of guide rail 5 is provided with the second hydraulic means 15, second hydraulic means 15 be arranged on the downside of installing plate 3 is connected with the rear side of the first hydraulic means 6, and automaticity is high, time saving and energy saving, simple to operate; The lower end of described first hydraulic means 6 is connected with detector probe 7, described detector probe 7 comprises the probe base 71 of insulation, many metal probes are provided with in probe base 71, metal probe is divided into current/voltage probe 72 and temperature probe 73, described temperature probe 73 is hollow structure, and its inside is provided with temperature sensor, and temperature sensor is thermal resistance 74, the temperature probe 73 that thermal resistance 74 fills in hollow is inner, and embedding is fixed on temperature probe 73 inside; The probe set 75 corresponding with metal probe quantity is provided with in described probe base 71, every root metal probe correspondence is movably arranged in probe set 75, the bottom of metal probe is provided with protuberance 76, protuberance 76 is threaded with the first hydraulic means 6, the metal probe between protuberance 76 and probe set 75 is provided with spring 77.When metal probe contacts with the electrode of lithium battery, by the elastic force of spring 77, certain downward acting force is imposed to metal probe, thus metal probe can be contacted reliably with the electrode of lithium battery.
The quantity of described metal probe is the six roots of sensation, comprise a temperature probe 73 and five current/voltage probes 72, a temperature probe 73 is positioned at the center of probe base 71, temperature probe 73 have concurrently detect current/voltage and detected temperatures function---the metal shell of its outside is for detecting current/voltage, the thermal resistance 74 of its inside is for detected temperatures, five current/voltage probes 72, centered by temperature probe 73, are circumferentially uniformly distributed.Because the electric current of lithium battery is comparatively large, so need to adopt many current/voltage probes 72.
Workbench 8 is also provided with on the upside of the center of described base 1, workbench 8 is provided with lithium battery 9 to be detected, the outside of lithium battery 9 is provided with shell mechanism 10, described shell mechanism 10 comprises detection shell 11, bonding pad 12 and brace 13, described detection shell 11 is by a left side, right two parts composition, by end face with end face, three fixing sides form every part, a described left side, right two parts are oppositely arranged to be fixed as one by screw and nut 14 and form the cover body that is made up of an end face and four sides, two panels bonding pad 12 is fixed together by welding with two panels brace 13 respectively, two panels brace 13 welds with the pole piece of lithium battery 9 respectively, two panels brace 13 is each passed through and detects shell 11 side.
In order to ensure passing through of big current in testing process, thicker copper coin is selected to weld with battery pole plates, but the copper coin laser welder that thickness is 1.5mm is difficult to be welded on battery pole plates, so first bonding pad 12 is welded on brace 13, again brace 13 is welded on pole plate, copper coin can be avoided like this to be welded direct on battery pole plates, and the nickel sheet overcurrent effect of 0.3mm is better, larger internal resistance can not be formed in junction again.And welding after more stable, so the measurement data of battery is reproducible, do not need the quality in order to ensure data and repeatedly carry out same test, avoid waste.After bonding pad is carried out; load onto left and right two parts of battery detecting shell 11 to battery top, be then that two parts are fixed by the screw of 1.6mm and nut 14 with radius, form protection; prevent outer lead from touching battery electrode column, battery is formed and destroys.And battery detecting shell adopts is ABS, part wall is thicker, can real working condition in real simulated battery PACK rear car, so that slip-stick artist can the temperature rise situation of electrolytic cell truly.Spray-hole can be flowed out to explosion-proof valve above security aspect shell, can ensure in extreme circumstances, to the timely pressure release of battery, can not blast be produced.ABS is injection molded for battery detecting shell, smooth surface, resistance to live the high temperature of 120 DEG C, flame retardant rating is V0 level.
The nickel sheet of bonding pad 12 material to be thickness be 0.3mm forms through Linear cut.Owing to adopting nickel, good welding performance, resistance is low, so the performance of super-high-current is good.The material that brace adopts is red copper, and plating nickel on surface, can make brace and bonding pad link together preferably.
Above the better embodiment of this patent is explained in detail, but this patent is not limited to above-mentioned embodiment, in the ken that one skilled in the relevant art possesses, can also makes a variety of changes under the prerequisite not departing from this patent aim.
