Battery washing test device

1、 Overview of battery washing test device:

Battery washing test machine BE-XD-6050(Number:201220243475）It is a new product developed by Dongguan Bell, This utility model relates to the technical field of battery testing equipment, specifically a battery washing testing machine, with a frame structureThere is a test box, with a washing box at the bottom of the test box and a rotating paddle inside the test boxThere is a drying device on the inner side of the body, and the input end of the rotating paddle is connected to the driving motor. The washing box is a lifting structureThe box body is constructed, and the washing box rises to form a sealed cavity with the upper edge of the testing box body. The rack body is equipped withThe control panel is connected to the water tank, and the washing tank is connected to the water tank through pipes. Its structural design is scientific and solves the problem of electricityPool washing * is manually carried out step by step, greatly reducing testing time, improving testing accuracy, and savingTime and effort saving.

2、 Purpose of battery washing test device:

2.01.Lithium ion battery pack for handheld electronic products;

2.02.Lithium ion battery packs for portable electronic devices that may be carried or used in pockets;

2.03.Battery packs that can be carried in pockets for other portable electronic products;

2.04.Install handheld electronic products with non user replaceable batteries/battery packs.

IIIThe experiment shall be conducted according to the following steps:

3.01.Solution preparation: Set the pH value to 11.0± 0.1Solution (can use NaOH with a mass fraction of 0.004%)

Heat the solution to (45 ± 2) ℃;

3.02.Soak: Fix the sample on the rotating device and place it in the solution (center of the battery)

Soak at a height of 300mm ± 10mm from the liquid surface for 0.5 hours, and maintain the temperature of the solution during the test

（45±2）℃；

3.03.Stirring: Fix the sample on a rotating device and rotate it in the solution for 0.5 hours at a speed of 60 r/min;

3.04.Dehydration: Remove the solution, rotate for 10 minutes at a speed of 800 r/min;

3.05.Drying: Place the sample in a high-temperature chamber and heat it for 0.5 hours at a temperature of (45 ± 2) ℃;

3.06.If the sample can continue to charge and discharge, follow the instructions（1）Continue discharging once according to the prescribed charging and discharging methods

End the test after the electric charging cycle; If the sample cannot continue to be charged and discharged, the test shall be terminated.

（1）Test charging program

The battery or battery pack should be charged according to the manufacturer's specified method.

Note: Before charging, the battery or battery pack should be discharged to the discharge cut-off voltage according to the manufacturer's specified method.

Test discharge program

The battery or battery pack is discharged at a constant current according to the manufacturer's specified current until the discharge cut-off voltage.
