Description

Technical Field

[0001] The present application belongs to the technical field of aging machines, and specifically relates to a charging pile aging test machine and a test system thereof that can realize self-circulation of test current. Background Art

[0002] Charging pile aging testing involves a series of tests, including voltage, current, and power consumption, to ensure the pile's technical and safety performance before commissioning. A charging pile aging machine is the primary device used to perform this testing. For charging pile manufacturers, aging testing is an essential step in the production process, known as the aging process.

[0003] See also Figure 1 The existing charging pile burn-in test process is as follows: the burn-in machine draws mains power from the mains interface, processes the current, and then outputs voltage and current to the charging pile under test according to the test standard. After the test is complete, the current flows out of the charging pile and is consumed by the load. The problem is that the test current is ultimately consumed by the load, resulting in energy waste. Utility Model Content

[0012] Beneficial technical effects:

[0013] This application provides a charging pile aging tester and test system capable of self-circulating test current. This system replaces the existing test load with a self-circulating test current, enabling the recycling of most of the test current. Field tests have shown that, for example, a load-consuming aging tester requires 10 kWh of electricity to complete a charging pile test. However, after implementing this application, only 1.5-2.0 kWh of electricity is required for testing, resulting in an energy saving of over 80%.

[0019] 10-aging machine body, 20-test current self-circulation system;

[0020] 210-device interface, 220-product interface. DETAILED DESCRIPTION

[0021] See also Figure 2-Figure 3 The charging pile aging test machine disclosed in this application, which can realize self-circulation of test current, includes an aging machine body 10 and a test current self-circulation system 20; the test current self-circulation system 20 is provided with a device interface 210 and a product interface 220; the device interface 210 is used to electrically connect to the aging machine body 10, and the product interface 220 is used to electrically connect to the charging pile to be tested.

[0022] The test current self-circulation system 20 is used to process the test current from the charging pile to be tested and feed the processed test current back to the burn-in machine body 10. As a result, the test current of the burn-in machine can form a closed loop between the burn-in machine body 10, the test current self-circulation system 20, and the charging pile undergoing the burn-in test, avoiding the energy waste problem existing in the existing load-consumption burn-in test process.

[0023] The burn-in machine body 10 can be any of the various burn-in testers known in the art. It generally includes a display module, a control module, an input module, a working power supply, a burn-in power supply, and an interface module. The burn-in power supply includes a transformer, a rectifier circuit, a filter circuit, and a voltage regulator circuit. The display module is used to display the dynamic changes of various test parameters. The control module is used to control the system functions of the burn-in machine body 10. The input module is used to input various burn-in test instructions. The working power supply is used to provide system power. The burn-in power supply is used to output burn-in test electrical signals (such as current and voltage) according to the instructions of the control module. The interface module is used to connect to the product to be burned-in tested.

[0024] The display module can be various display devices such as a touch screen, the control module can be an industrial control microcomputer, the interface module can be flexibly configured into a single interface or multiple interfaces as needed, and the rectifier circuit, filter circuit and voltage stabilizing circuit can be various standard modules or circuits in the existing technology.

[0025] The test current self-circulating system 20 includes a rectifier module, a voltage regulator module, and a feedback module. The rectifier module is used to introduce the test current from the product interface 220, the voltage regulator module is used to adjust the voltage of the test current from the rectifier module, and the feedback module is used to feed the test current from the voltage regulator module back to the burn-in machine body 10 through the device interface 210 to form energy feedback. The rectifier circuit, voltage regulator circuit, and feedback circuit can all adopt existing circuit structures or functional modules and are not described in detail here.

[0026] Principle and effect description:

[0027] The aging machine introduces the test current from the mains. Assuming that the power consumption at this time is P0 (U0I0), the test current is fed into the charging pile under test through the aging machine, and then flows into the test current self-circulation system 20 through the product interface 220. After rectification and voltage stabilization by the rectifier module and the voltage regulator module, it is fed back to the aging machine through the device interface 210. The aging machine determines the power drawn from the mains in real time based on the power of the feedback current. Assuming that the power of the feedback current is P1 (U1I1), then after the feedback current of the test current self-circulation system 20 arrives, the control module will adjust the power drawn at this time to P0-P1. Assuming that the load consumption test process requires 10kW of power per hour, after adopting the test current self-circulation system 20, the aging test can be completed normally by drawing 1-2kW of power per hour.

[0028] The above describes the technical solution and technical effects of the present application in detail in combination with the drawings and specific embodiments of the specification.
