Description

Technical Field

[0001] The utility model relates to the technical field of supercapacitor module aging test, and in particular to a supercapacitor module charge and discharge aging test tool. Background Art

[0002] As a new type of energy storage device, supercapacitor modules are increasingly being used in wind power generation, automotive HEVs, military starting power supplies, and microgrid equipment due to their unique charging and discharging characteristics. Since the operating voltage of a single supercapacitor is relatively low, typically only 1V-4V, with a typical single-cell voltage specification of 2.7V, actual applications often require voltages of 16V, 48V, 54V, 75V, 125V, or even higher to meet the needs of these devices, they are often used in both series and parallel connections. Due to the differences between supercapacitor cells, simple series charging can lead to unbalanced charging, shortening the lifespan of the supercapacitor module. Therefore, a well-designed circuit configuration is required to ensure stable supercapacitor charging and discharging. A supercapacitor module consists of multiple supercapacitor cells connected in series, along with voltage balancing and discharge stabilization systems. To ensure high quality and improve production efficiency, a supercapacitor module charge and discharge aging test fixture is essential. The existing charge-discharge aging test method for supercapacitor modules is to power a single supercapacitor module with a DC power supply, then discharge the module using a load instrument, detect the discharge time, and implement the aging test. Therefore, the existing charge-discharge aging test device for supercapacitor modules has low test efficiency and slow test speed. Utility Model Content

[0015] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0016] Example 1, as Figures 1 to 2As shown, a supercapacitor module charge and discharge aging test tool includes a test base 2 and a console 1. The console 1 is arranged at one end of the test base 2. The top surface of the test base 2 is provided with multiple test stations 21. The test stations 21 are provided with input voltage and current meters 22, output voltage and current meters 23 and test interfaces 24. The top surface of the console 1 is provided with a display screen 11, a start switch 12 and a setting key 13. The top surface of the console 1 is provided with multiple indicator lights 14 corresponding to the multiple test stations 21. A test circuit board 25 is provided in the test base 2 corresponding to each test station 21. A timer 26 is provided on the test circuit board 25. The timer 26, the input voltage and current meter 22, the output voltage and current meter 23 and the test interface 24 are electrically connected to the test circuit board 25.

[0017] As a more specific technical solution of the utility model.

[0018] The test base 2 is provided with a plurality of test stations 21 at intervals along the length direction thereof.

[0019] The control board 15 is provided in the console 1. The control board 15 is electrically connected to the display screen 11, the start switch 12, the setting key 13, and the test board 25. All the test boards send signals to the control board.

[0020] The indicator light 14 is an LED light.

[0021] The setting key 13 includes a set key 16 , a plus key 17 , and a minus key 18 .

[0022] The testing principle of this utility model is:

[0023] Step 1: The worker sets the parameters of the supercapacitor module such as the number of charge and discharge cycles, charging time, discharge time, and discharge qualified time through the setting key 13 of the console 1.

[0024] Step 2: A worker connects multiple supercapacitor modules to the test station 21 , and inserts the pins of the supercapacitor modules into the test interface 24 .

[0025] Step three: After the worker presses the start switch 12, the utility model automatically runs: charging countdown - discharging timing - charging countdown - discharging timing... until the set number of charge and discharge cycles is accumulated. The timer 26 is used for timing and sends a signal to the test circuit board. The utility model automatically stores the discharge time of each supercapacitor module during the last discharge and compares it with the preset discharge qualified time. If it is greater than the set discharge qualified time, the indicator light at the corresponding position on the control panel is green, otherwise it is red.

[0026] Step 4: After the charge and discharge cycle is complete, the worker can press the plus key 17 "+" and the minus key 18 "-" to view the actual discharge time of the corresponding supercapacitor module. During the test, the utility model can use a voltage and current meter to check whether the corresponding electrical parameters of the supercapacitor are normal. The test tool has the advantages of fast testing speed, batch testing, and low cost.
