Battery washing test machine,   with a test Chamber body, the lower part of the test chamber body is  with a washing chamber, and the test chamber has a rotating paddle a drying device arranged on the side of the test box, and the input end of the rotating paddle is connected to the driving motor. The washing chamber  with a lifting structure, and the washing box rises to form a sealed cavity with the upper edge of the test box, and the frame body has a control panel and a water tank, and the washing chamber is electrically connected through the pipeline and the water tank. The structure design is scientific, and the battery washing is completely solved by manual step by step, which greatly shortens the test time, improves the test precision, saves time and labor.

Feature 

• The inner  of the machine is made of  standard 1.2mm thick SUS#304 stainless steel, and the outer box is electrostatic painting of standard 1.2mm electrolytic palte.

• Special fixture for washing and rotating paddle material: SUS#316 stainless steel, with strong acid and alkali resistance and corrosion resistance. A set of fixtures with small batteries and a large battery (such as the battery used by IPAD), making it easy for users to change fixtures, making them more convenient to use.

• The equipment door is equipped with a safety sensor switch. When the test box door is opened, the equipment will be forcibly powered off, unable to operate, to prevent damage caused by misoperation by non-professional operators, and to maximize the personal safety of the test personnel. protection

• The battery washing test machine is provided with a washing box, and a rotating paddle is arranged in the test box, and is driven by a servo motor and a servo driver to accurately control the rotating speed .

• The washing paddle has a lifting structure, which has two advantages for the user:

• 1. The battery washing liquid can be recycled, and it is not necessary to add water and a solution for each test, thereby eliminating the trouble of the solution ratio and realizing the reuse of resources. Shorten the test time by 20-30 minutes;

• 2. When installing the battery, manually lift the wash paddle, do not need the tester to bend over and install in the washing tank. Each test can install 4 batteries, which is for the operator. It is a more user-friendly design that fully reflects our & people-oriented design philosophy.

• The water tank of the machine is separated from the solution tank. The customer does not need to directly add the better solution to the washing tank when adding the solution. During the test, the water vapor will cause water shortage in the washing tank. At this time, the equipment can automatically control the water tank. The test chamber is added with a well-matched solution to ensure the concentration of the solution.

• The temperature control of the equipment adopts intelligent P.I.D control, and the PLC temperature module is the Japanese Omron temperature module. The temperature control is precise and the error is very small. The equipment adopts HMI control, the structure design is scientific and rigorous, and the operation is automated. It only needs to set the program on the man-machine interface to run automatically. In the industry state where the washing test is compulsory detection, the artificial battery washing is solved. Inconvenience and hysteresis, shortening the test time improves the test accuracy and efficiency, saving resources and labor costs.

Battery washing test machine parameters

Working principle

After the purified water is added to the liquid recovery tank, adjust the pH of the test water by adding sodium hydroxide solution. After the PH meter measures the solution, click      the test to start: gradually complete the test steps of soaking-stirring-dehydration-drying according to the standard requirements. . After the test is completed, the system's three- color sound and light alarm light will sound and light alarm, and the test is over.

According to the standard  GB31241-2014

The system adopts advanced high-resolution PLC+ industrial touch screen automatic control. The operation of the equipment is completed on the touch screen. The operation is simple and convenient. The whole test system consists of two parts: the inner barrel and the outer box. It has strong explosion-proof performance even if it is The battery explodes in the test box and does not cause damage to the test box.

The test is carried out after the sample is fully charged according to the specified test method. The test is carried out as follows:

a) Dosing:Configure a solution with a pH of 11.0 ± 0.1 (using a 0.004% NaOH solution) and heat the solution to (45 ± 2) °C

b) Soaking:The sample was fixed on the rotating device (see Appendix E.3), and then the sample was placed in the solution (the center of the battery was at a height of 300 mm ± 10 mm from the liquid level) and immersed for 0.5 h. The temperature of the solution was maintained during the test (45 ± 2). ) °C

c) Stirring:The sample was fixed on a rotating device and rotated in the solution for 0.5 h at a speed of 60 r/min.

d) Dehydration:Remove the solution and turn it for 10 minutes at 800r/min

e) Drying:The sample was placed in a high temperature chamber for heating for 0.5 h at a heating temperature of (45 ± 2) °C.

f) If the sample can continue to charge and discharge,Then, the test is terminated after continuing the discharge charging cycle according to the charging and discharging method specified in 4.5; if the sample cannot continue charging and discharging, the test is terminated.

Note:The sample should not ignite or explode.
