Description
Technical field
The present invention relates to a kind of battery charging and discharging system, especially a kind of battery charging and discharging chucking appliance system.
Background technique
With the continuous improvement of China's new-energy automobile sales volume, China's new-energy automobile volume of production and marketing in 2017 is close to 800,000
, it is contemplated that surpass to the year two thousand twenty, pure electric automobile and plug-in hybrid-power automobile production capacity up to 2,000,000, accumulative volume of production and marketing
5,000,000 are crossed, therefore the raising of electric car sales volume necessarily drives the batch production of Vehicular dynamic battery, is produced in power battery
Need to carry out it chemical conversion and basic parameter test experiments later, it is therefore desirable to multiple charge-discharge test is carried out to battery.Together
When each battery in use, need retired, and generally require pair when the 80% of its capacity attenuation to initial capacity
Retired battery carries out echelon utilization, thus to improve the utilization rate of battery.It is past when carrying out echelon utilization to retired power battery
Toward needing to test the parameters such as battery capacity, internal resistance, self discharge, needed during testing above-mentioned parameter pair
Battery carries out multiple charge-discharge test.
It generally requires to carry out battery multiple charge and discharge during carrying out the test of above-mentioned battery fundamental performance parameter
Experiment, and traditional battery clamp needs manual hand manipulation to compress, and contact resistance can be also generated between fixture and battery,
If manual operation is improper to will increase contact resistance；Efficiency save the cost not only can be improved in the battery clamp of superior performance, and
And experimental precision can be improved.
For this reason, it may be necessary to design a kind of electromagnetic type fixture, the electromagnetic induction principle of solenoid is used the power on to control fixture, when
When solenoid no power, fixture is in open configuration under initial tension of spring effect；When solenoid is powered, what solenoid generated
Electromagnetic attraction overcomes initial tension of spring, and fixture is in clamped condition.Therefore only need to control solenoid electricity in terms of controlling fixture
The on-off of stream can greatly improve working efficiency in this way.Simultaneously helical loop current can be flowed through by adjusting
Size therefore can effectively improve battery to adjust the size of pressure between battery pole ear and ferromagnetism battery pole ear support
The resistance value of fixture is effectively reduced in the reliability and convenience of positive and negative anodes high current charge-discharge, durable, improves charging/discharging apparatus
Charging or discharging current precision, it is easy for installation, suitable for larger assembly line.
Summary of the invention
The purpose of the present invention is to provide a kind of electromagnetic type battery charging and discharging chucking appliance systems, are mainly used for a large amount of battery screenings
Have the function that quick-clamping in the process and reduces contact resistance.
To reach above-mentioned requirements, the present invention adopts the following technical scheme:
A kind of electromagnetic type battery charging and discharging chucking appliance system, there are two be respectively used to clamp battery positive and negative electrode battery pole ear for tool
Fixture, two fixtures are mounted on bottom plate, and setting can prevent battery plus-negative plate contact from the vertical of short circuit occurs between two fixtures
To baffle, bottom plate two sides are equipped with transverse baffle for fixing battery, each fixture include fixture base, battery pole ear support,
Spring, column, battery pole ear pressing plate, core clamping-plate, solenoid, iron core screw, the fixture base are mounted on bottom plate, fixture
