The temperature cycle tester is used to simulate the ability of the battery pack/battery system/battery module/cell sample to adapt to the environment under different temperature and humidity conditions. Product features and functionality 1 .The temperature control is PID microcomputer automatic calculation intelligent temperature control table, PV/SV display at the same time, the required temperature can be freely set according to the individual's will within the allowable range of the machine temperature, and its temperature control can be ensured by the PID parameter setting in the table. Accuracy can also be calculated by the system itself to calculate the appropriate temperature control parameters, while the temperature control table can set the 30-stage humidification program to control the heating rate (average humidity, nonlinear no-load). 2.Warm-in force CA (K) TYPE temperature sensor, the output is 1 2V. 3.The current controller adopts the imported thyristor solid state relay (SSR) without contact and no spark phenomenon, which maintains the high stability of the current and automatically adjusts the output ratio through the temperature controller signal. 4.Timer: electronic digital display, timed automatic temperature control, temperature to time, time to cut off power supply (when the timing switch points to the open position, the actual temperature on the temperature control table - PV value reaches the set temperature - SV value When the timer reaches the set time, the machine's heating, motor power and alarm prompts are cut off, only the display power supply and power supply of the control instrument are kept and the cooling speed is accelerated, thus ensuring The time accuracy of the work saves the loss of power, and it is convenient to observe whether the temperature inside the box is normal when the work is completed 5.Structural design features: outer box cold-rolled plate baking paint + insulation cotton + inner box stainless steel plate, and this structure is also adopted on the door of the box, the tempered glass of the observation window is thickened, effectively preventing the damage of the box caused by the possible explosion, force; 6.Explosion-proof door lock: The door door is equipped with an explosion-proof door lock. When the pressure inside the box is large, the door can be automatically opened, and the strong airflow will not be destroyed. At the same time, the door can be opened twice after the test is completed.

The instrument has a built-in forced air circulation loop. The wind source is driven by the circulating motor to drive the wind wheel through the electric heater, and the hot air is sent from the air duct to the inside of the oven, thereby reducing energy loss and ensuring temperature uniformity in the box. When the closing action causes disturbance, the air circulation system can quickly return to the operating state temperature value, open the air inlet and outlet, the air circulation is smooth, the air exchange is fast, and the concentration of the combustible gas is too high to cause...

a) Test object is lithium ion battery b) After the test object is charged according to the method of 7.1.1 c) Put it into the temperature box, the temperature of the temperature box is adjusted according to Table 2 and Figure 1, the number of cycles is 5 times. After the test, it should be observed at the test temperature for 1 h. Temperature cycling test temperature and time of a cycle Schematic diagram of temperature cycle test
