Quality Control
QA/QC Introduction
QA/QC IntroductionEach charger goes through at least 16 testing phases:
1) Charging performance
2) Discharging performance
3) Capacity evaluation
4) Internal resistance testing
5) High temperature testing
6) Low temperature testing
7) Aging cycling
8) Bump testing
9) Vibration testing
10) Constant humidity testing
11) Safety testing
12) Load testing
13) External structure
14) Storage
15) Voltage checking
16) Packaging mark
For large-scale quality control, we also do the following:
1) Select raw material such as cells and PCBs from trusted suppliers only. All of our main suppliers have CE or UL certification. They also take responsibility for our goods.
2)Moreover, we have the exact machinery to check the cell and PCB again in our own factory.
3) Before mass production, we send free samples for customer confirmation, and get the signed sample as the standard of the mass order.
Test Equipment and Facilities
Name:Solar Cell Tester
Description:It tests the electrical performance of photovoltaic cells under simulated sunlight. A xenon arc lamp with an optical filter provides a close match to the Air Mass 1.5 Global (AM1.5G) solar spectrum. It measures current-voltage (I-V) characteristics of cells with dimensions up to 156 mm x 156 mm at 1 sun intensity. Its high resolution also permits testing of very small area devices. Separate current and voltage probes on the top and bottom of the cell permit four-point (Kelvin) I-V measurements. A calibrated monitor cell is located on the test plane to monitor the light intensity. A computer with user friendly software adjusts the lamp intensity, controls the measurement process, and acquires cell performance data. A programmable electronic load varies the resistance across the cell to measure its I-V characteristics. The computer plots the I-V curve and displays a variety of cell characteristics. Curves and data can be printed and stored on disk.
