The battery memory effect is a phenomenon that occurs when a battery crystallizes internally during repeated charging and discharging. This effect is caused by repeated partial charging and incomplete discharging of the battery, which makes the battery seem to “remember” the previous state of charge, resulting in subsequent charging only to the level of the previous incomplete discharge, and thus unable to fully utilize its rated capacity. Origin of Memory Effect The memory effect was first observed in nickel-cadmium batteries used in satellites in the early 1960s when NASA used nickel-cadmium batteries extensively as the primary power source for various space missions. However, scientists found that these batteries showed significant degradation in performance and capacity after multiple partial discharges and recharges. Further experiments and observations showed that these batteries formed crystals on the surface of the electrodes after many incomplete discharges, thus limiting the electrochemical reaction capability of the batteries,…

AGVs (Automated Guided Vehicles), are automated transportation tool that are automatically guided by magnetic strips, tracks, or laser lights and travels according to a predetermined path. With the rapid development of artificial intelligence, AGV has become more intelligent and efficient, for example: AGV can be automatically charged to achieve 24-hour continuous work; data management allows real-time monitoring in the background to maximize management efficiency; advanced safety features, precise positioning, controllable speed and path make AGV operation safer and more reliable, which greatly improves work efficiency. Therefore, it is widely used in production lines, warehouses and logistics centers. AGV batteries are specially designed for AGVs and provide the energy needed for AGV drives.

UPS batteries in data centers play a crucial role in providing backup power in the event of a mains failure, ensuring the reliable and efficient operation of data centers. In the following, we will explore the various factors to consider when selecting the right UPS battery type for data centers. First, let’s understand the working principle of an online UPS. When the mains power is normal, the voltage from the grid passes through a filter to remove high-frequency interference before entering the rectifier. The rectifier converts AC power into DC power, with a portion charging the UPS battery via the charger, and the rest feeding into the inverter. The inverter then converts DC power back into AC power for the load (such as servers, storage, and network peripherals). In the event of a mains power outage, the rectifier input is disconnected，the the UPS battery begins to discharge. The current passes…
