Advantages such as lithium ion battery has voltage height, specific energy height, recycles often, storage time is long, not only on portable electric appts, be used widely, and be widely used in big-and-middle-sized electrical equipment aspects such as electric automobile, electric bicycle and electric tool as mobile phone, Digital Video and laptop computer.Lithium ion battery mainly comprises column lithium ion battery, rectangular lithium ion battery, polymer Li-ion battery.Wherein rectangular lithium ion battery is because positive and negative terminals all is in battery one side, and the phenomenon that occurs the both positive and negative polarity short circuit in testing easily takes place, and can reduce the security of rectangular lithium ion battery in the test.
Simultaneously the thermal diffusivity of current battery test fixture is bad, causes in the battery testing process temperature rise very high, and temperature raises and further the battery testing result had a significant impact, and has reduced the reliability of rectangular lithium ion battery test data.Because the current battery test fixture lacks the collection to the battery surface temperature, just can not carry out temperature alarming timely when battery goes wrong, reduce the security of rectangular lithium ion battery in the test greatly.
The utility model content
The purpose of this utility model is at the technological deficiency that exists in the prior art, and a kind of rectangular lithium ion battery test fixture is provided.
For realizing that the technical scheme that the purpose of this utility model adopted is:
A kind of rectangular lithium ion battery test fixture, comprise the base plate that is evenly equipped with the heat radiation through hole, be fixedly installed on the left side limiting plate and the right side limiting plate of the base plate left and right sides respectively, be arranged on the front apron of base plate front end vertically, be arranged on the rear position margining plate of base plate rear end vertically and be arranged on two corresponding with rectangular lithium ion battery ear-pole respectively probes on the front apron, also comprise U-shaped battery gusset plate, described battery gusset plate is fixedlyed connected with base plate across base plate both sides and its two ends, is provided with allowable temperature simultaneously and gathers the through hole that line enters on described battery gusset plate.
It is relative adjustable to adopt slotted hole and bolt to cooperate to realize the position between described left side plate, front apron and rear position margining plate and base plate respectively.
Between described probe and front apron, to adopt slotted hole and bolt to cooperate with the realization position between left side plate and front apron relative adjustable.
Be set with locating piece at top, described battery gusset plate center, be formed with on the described locating piece and the corresponding line hole of through hole on the battery gusset plate, also be formed with threaded hole the collection line in the line hole is located at described locating piece sidepiece simultaneously by screw.
The described front apron outside also is connected with the fender of being made by transparent toughened glass.
Compared with prior art, the beneficial effects of the utility model are:
All structures of the utility model anchor clamps all can arbitrarily be dismantled or be assembled, and pass through to regulate the position of rear position margining plate, side limiting plate, probe, and are safe, convenient, go for the test of different batteries.Thereby the temperature acquisition line is installed in the collection that battery surface is realized the battery surface temperature in the battery testing process by the through hole on the battery gusset plate.Go out the circular hole of a plurality of heat transmissions simultaneously in the back-plane design of testing tool, can effectively control the temperature rise in the battery testing process, and then reduce the influence that the battery testing result is caused because temperature is too high.
