New energy vehicle testing: Low consumption, stable control, zero stop line, precise prediction of m

Lin, the materials research manager of a new energy vehicle company, once suffered from the maintenance problems of testing entire vehicle-mounted photovoltaic panels: "We tested a 1.8m¡Á2.5m vehicle-mounted photovoltaic panel. The light intensity of the traditional xenon lamp equipment fluctuated by 5%, and the data from the 720-hour aging test drifted by more than 4%. The deviation in material lifespan assessment reached 2 years. What was even more troublesome was that the lifespan of the xenon lamp was only 1000 hours, and the cost of replacing the lamp once exceeded 500,000 yuan. Frequent lamp replacements led to the production line being shut down more than 10 times, resulting in a production loss of millions of yuan."

The customized 3A-level LED steady-state simulator by Saifan precisely addresses the dual pain points of "precision + maintenance". The equipment adopts a custom 1.8m¡Á3.6m frame size, with 288 sets of highly consistent LED arrays combined with precise temperature control technology. The uniformity of the light spot is ¡Ü¡À2.5%, and the temperature difference of the entire panel is ¡Ü¡À1¡æ, accurately replicating the real outdoor lighting conditions. With the independently developed steady-state driving technology, the light intensity stability is as low as ¡À0.05%/8 hours, and the light intensity drift during continuous 1000-hour testing is ¡Ü¡À0.8%. The spectral matching degree remains stable at A+ level, ensuring that the material testing mechanism is consistent with outdoor conditions, and the data repeatability is ¡Ü¡À0.5%. 

"Now, the entire panel can be tested in one go, with no production line downtime throughout the year. The maintenance cost has decreased from 500,000 yuan to 100,000 yuan, a reduction of 80%." Lin said, "By leveraging the dynamic light intensity simulation function of the equipment, our team successfully developed a new type of anti-aging coating. The lifespan of the vehicle-mounted photovoltaic panels has been extended from 5 years to 8 years." "Equipment of the same level imported from abroad costs 12 million yuan and has a delivery period of 6 months. The customized model of Sefan saves 6 million yuan directly, and can be delivered within 45 days. It also provides on-site commissioning and training services, completely breaking the import monopoly."
