Description
Technical field
The utility model belongs to lithium ion battery technical field of measurement and test, specifically relates to a kind of li battery shell cover plate brace and pole overcurrent device for testing temperature rise.
Background technology
Lithium ion battery has the advantages such as operating voltage is high, working temperature is wide, long circulation life and has been used widely, particularly in recent years lithium ion battery as vehicle-mounted electrical source of power and fast development.
Lithium ion battery is mainly by both positive and negative polarity active material, electrolyte and prevent that the barrier film of both positive and negative polarity short circuit from forming.Conventionally both positive and negative polarity active material is coated on aluminium, Copper Foil collector, then barrier film is directly made to battery core by lamination or the mode that turns around between both positive and negative polarity collector; Pack battery core into stainless steel, aluminum hull or plastic housing, the electrolyte that reinjects sealing and make square or cylindrical battery.
Electrokinetic cell is as needing to support different multiplying current discharge in vehicle power use procedure, and wherein inner battery core and extraneous conducting are that the lug that welds on collector is connected with housing cover lug and draws by riveting pole, the design of its housing cover has extremely important impact to battery conveyance capacity, in the time that electric current flows through cover plate because cover plate materials is selected different, cover plate pole heating when riveted joint gap etc. factor impact causes overcurrent, when its overcurrent generate heat the temperature that causes while exceeding the maximum temperature of BMS battery management system design management system send warning, automatic cut-off power easily causes electric automobile security incident.
Utility model content
For the technical problem existing in prior art, the purpose of this utility model is to provide a kind of li battery shell cover plate brace and pole overcurrent device for testing temperature rise.
To achieve these goals, the technical scheme that the utility model adopts is: a kind of li battery shell cover plate brace and pole overcurrent device for testing temperature rise, comprise hot box, the spring supporting platform stirring to prevent it for clamping battery container cover plate to be tested is installed in described hot box, the brace of described battery container cover plate to be tested and pole are all by wire harness and the battery testing cabinet electrical connection that is placed in hot box outside and can carries different currents, the pad being nested with on the brace of battery container cover plate to be tested is electrically connected with temperature sensor by platinum filament thermocouple.
The utility model can also be implemented by the following technical programs:
Brace and the pole of described battery container cover plate to be tested all clamp wire harness by crocodile clip.
The platinum filament thermocouple welding being connected with described temperature sensor is on pad.
Li battery shell cover plate brace of the present utility model and pole overcurrent device for testing temperature rise, energy Validity Test battery cover plate structure part brace and pole the highest resistance to overcurrent and temperature level data, thereby for providing strong data supporting in battery design and BMS management system development process.This testing apparatus had both gone for the test of quadrate lithium battery cover plate of outer casing brace and the temperature rise of pole overcurrent, also went for the test of cylindrical lithium battery cover plate of outer casing brace and the temperature rise of pole overcurrent.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
In figure, Reference numeral implication is as follows:
1-hot box 2-spring supporting platform
3-battery container cover plate to be tested 4-pole
5-brace 6-pad
7-temperature sensor 8-battery testing cabinet.
Embodiment
For further describing the utility model, below in conjunction with accompanying drawing, the utility model is described in further detail.
A kind of li battery shell cover plate brace shown in Fig. 1 and pole overcurrent device for testing temperature rise, comprise hot box 1, the spring supporting platform 2 stirring to prevent it for clamping battery container cover plate 3 to be tested is installed in hot box 1, the brace 5 of battery container cover plate 3 to be tested and pole 4 are all clamped wire harness and are placed in hot box 1 outside and can carry the battery testing cabinet 8 of different currents to be electrically connected by crocodile clip, and the pad 6 being nested with on the brace 5 of battery container cover plate 3 to be tested is electrically connected with temperature sensor 7 by platinum filament thermocouple.
Battery container cover plate 3 to be tested is placed on hot box 1 inner spring brace table 2 and is clamped, and clip brace 5 and pole 4 with crocodile clip, by airtight hot box 1 good, prevent the impact of extraneous air-flow on test result, then platinum filament thermocouple point is welded on the extraneous pad 6 of cover plate and external temperature Acquisition Instrument 7; When experiment test by the output current size of battery testing cabinet 8 is set, in the time that flowing through brace 5 from pole 4, electric current can produce the heat of different sizes due to the impact of itself internal resistance, and with the data of temperature level by temperature sensor 7 acquisition and recordings, realize temperature sensor 7 and gather the maximum temperature of pole 4 under different current condition.
Above content is only to design example of the present utility model and explanation; affiliated those skilled in the art make various amendments to described specific embodiment or supplement or adopt similar mode to substitute; only otherwise depart from the design of utility model or surmount this scope as defined in the claims, all should belong to protection range of the present utility model.
