The purpose of the battery charging performance test is to check the charging ability of the lithium-ion battery in different states. Battery charging performance test includes battery slow charging performance test and battery fast charging performance test. Among them, battery slow charging refers to a mode of charging at a lower rate. The battery slow charging performance test is performed at a specific temperature, including low temperature, normal temperature and high temperature environment, focusing on charging capacity, charging energy and charging time. The specific test procedure is as follows. 1) Discharge the battery to the specified discharge cut-off conditions in a…

The purpose of the battery charging performance test is to check the charging ability of the lithium-ion battery in different states. Battery charging performance test includes battery slow charging performance test and battery fast charging performance test. Among them, battery fast charging refers to the mode of charging at a higher current rate. Fast charging is usually the act of charging at high current rates in a low SOC state of the battery system. Battery fast charging performance tests were conducted at designed current rates in low, normal and high temperature environments. The specific test procedure is as follows. 1) Discharge the…

The outdoor sign gobo projector light is high-definition and waterproof, and can work outdoors for a long time. You can choose to customize the pattern, and you can choose single color, double color, or multi-color for pattern customization. The advantage of the projector lamp is that it can use light and shadow to restore the picture or display a personalized and creative logo on the wall or floor, and can be connected to a switch to switch color chips and patterns for flexible display. Projection lamps can be divided into indoor projection lamps, outdoor projection lamps, static projection lamps, dynamic projection lamps, multi-image…

Our star ceiling panels are state of the art modular star panel systems that create the most realistic night sky effects while  providing acoustical value to your space. Such optic star ceiling kit allows you to DIY the star to any patterns, such as milky way, moon, universe, car brand LOGO, cartoon image and so on. The artistic effects of colors are diverse, full of dynamic, texture and space. At the same time, the optical fiber is flexibly transmitted, which can freely guide the light to the desired location according to different ideas. The light emitted by the fiber optic illumination filters the cold light of…

Multiple strings of end-light optical fibers can be used for indoor and outdoor lighting, with 7 color lighting changes and various lighting styles. The diameter of optical fiber is generally 0.75mm, and the number of cores is a multiple of 7. Optical fiber cables are available in 7, 14, 21, 28, 35, and 42 strand types. Multi-stranded end-launch cables consist of multiple strands of polymer fibers surrounded by a protective sheath to provide mechanical protection. The material of the starry sky swimming pool uses optical fiber cables, which can be multi-core or single-core optical cables. Laying the fiber optic cable at the bottom of…
