Perkenalkan:

The popularization of smartphones, laptops and wireless charging devices has driven the rapid development of the fast-charging power industry. Various fast charging protocols such as QC, PD, PPS and SCP are widely applied, and the power range of power supply products covers from tens of watts to hundreds of watts. Electronic components follow the bathtub curve failure law. Most early failures of products are caused by component defects, cold solder joints and process flaws. If defective products flow into the market without sufficient aging screening, output drift, overheating and even safety accidents may occur, increasing after-sales costs and damaging brand reputation.

Factory accelerated aging test applies thermal stress and electrical stress to stimulate potential internal defects of power supplies under laboratory conditions, exposing early failures inside the factory. Traditional simple aging equipment has disadvantages such as a small number of channels, no constant temperature environment, lack of real-time data collection and insufficient safety alarms, which makes it difficult to meet the batch testing requirements of multi-specification fast chargers. High-performance battery charger tester can perform multi-channel load aging, constant temperature environment control, real-time electrical parameter acquisition and programmable timing test simultaneously to realize reliability durability verification of full-specification power supplies. The research object of this paper is the LISUN SY65240T charger/adapter power supply aging rack (constant temperature).

1 Principles of Power Supply Accelerated Aging and Reliability Durability Test

Accelerated aging test is mainly based on the Arrhenius accelerated life theory. Without changing the failure mechanism, the ambient temperature is appropriately increased together with rated/alternating load to shorten test time and simulate the long-term actual working conditions of products. In addition to continuous loaded aging, reliability durability test includes on-off cycling, multi-voltage surge and fast charging protocol switching condition simulation to assess the output stability of power supplies under repeated start-stop, grid voltage fluctuation and switching of different fast charging modes.

During the test, the output voltage, current and power of the equipment under test (EUT) as well as temperature changes need to be continuously monitored to observe output deviation, false protection triggering and abnormal heating. Batch aging data statistics can evaluate the consistency of batch products and guide the optimization of component selection, PCB process and heat dissipation structure. For charger products, it is also necessary to be compatible with various fast charging protocols and simulate the complete battery charging process to realize durability assessment close to real application scenarios.

2 System and Specification Parameters of LISUN SY65240T Penguji Pengisi Daya Baterai

The LISUN SY65240T series constant temperature aging rack is an integrated battery charger tester for chargers, power adapters and wireless chargers. It can complete factory accelerated aging and reliability durability test of full-range power supplies from low voltage to high voltage and low current to high current, supporting mainstream fast charging protocols including QC, PD, FCP, SCP, PPS and AFC. It is suitable for mass production quality inspection on production lines and laboratory R&D verification.

The complete equipment consists of a constant temperature aging cabinet, multi-channel electronic load modules, upper computer monitoring system and safety protection modules. The cabinet adopts a 6-layer cold-rolled steel plate layered storage structure with double-opening folding tempered glass doors. The temperature control system realizes constant temperature control from room temperature to 45℃ ±5℃, with over-temperature exhaust and low-temperature heating functions. The control system is equipped with dedicated Chinese and English aging software to customize load parameters and collect voltage, current and power in real time. It supports CC constant current and CV constant voltage load modes. Channels can be connected in parallel under CC mode to expand high-power testing. Programmable on-off timing and automatic load switching are available. Built-in over-temperature and smoke dual alarm protection is configured. LS-RT30KVA-3G transformer control module is optional to perform multi-voltage ON/OFF surge aging test on EUT to simulate grid voltage fluctuation.

3 Practical Test Application of Battery Charger Tester

In mass production quality inspection scenarios, place the chargers to be tested on each station of the aging rack. Connect the AC terminal to the input socket and the output terminal to the USB/Type-C load interface. Set constant temperature, load mode, aging duration and on-off timing in the upper computer software, then start batch aging test. During the whole test process, the software automatically records voltage, current and power of each channel. The equipment will alarm automatically when parameters are abnormal or over-temperature occurs, so operators can quickly locate failed samples and complete batch product screening.

In R&D reliability durability verification stage, this battery charger tester is used to complete multi-dimensional tests: first, long-term continuous aging under high temperature and full load to verify the long-term output stability of power supplies under high temperature and full load; second, programmable on-off cycle test to simulate repeated power on/off in daily use; third, voltage surge module is optional to switch input voltages such as 90V, 110V and 220V to simulate grid fluctuations in different regions; fourth, switch load with different fast charging protocols to test the working status of power supplies during protocol handshake and mode switching. By exporting complete timing data and test reports, R&D engineers can identify weak points of products and optimize circuits, component selection and heat dissipation design to improve overall product reliability.

In practical operation of the equipment, power calculation is required when selecting the transformer module. The selected power = single channel load power × number of channels ÷ conversion efficiency of EUT (generally higher than 80%) to ensure the surge aging module matches the load capacity of the whole machine.
