Common faults of AGV lithium battery pack, safe use of AGV lithium battery pack

Common faults of AGV lithium battery pack, safe use of AGV lithium battery pack. With the gradual high temperature in summer, the frequency of AGV lithium battery problems has increased. In fact, AGV users are concerned about the life of lithium batteries on the one hand, but on the other hand they are incorrectly used. Can't afford to toss. Below, the author of Energy Storage will explain to you the common faults of AGV lithium battery packs and the safe use of AGV lithium battery packs. Common faults of AGV lithium battery pack ①Battery explosion: The sub-capacitor has common faults, poor diaphragm closing and closing, and internal short-circuit faults. ②Low battery power: Cause: small amount of material attached, large distance between the two sides of the pole piece, less lithium battery electrolyte, low redox potential of lithium battery electrolyte, low diaphragm porosity, and ultra-thick core When the volume is divided, the cathode material of the positive battery is not filled with electricity and the specific volume of the positive battery is smaller. ③High internal resistance of the rechargeable battery: cause: virtual connection between the cathode sheet and the pole ear, the virtual connection between the positive stage sheet and the pole ear, the virtual connection between the positive stage ear and the backboard, the virtual connection between the cathode ear and the shell, the bolt and the bending machine touch the inside The resistance is large, no conductive agent is added to the positive stage, the electrolyte of the lithium battery has no lithium salt, the rechargeable battery has short-circuit failure before, and the diaphragm paper has a small porosity. ④The working voltage of rechargeable battery is low: the electrolyte of the lithium battery pack is decomposed, there is residue, water in the positive stage, the customer's pcb circuit board is powered off, the customer does not meet the regulations, vibration marks, micro-short circuit failure, and dendrites caused by the cathode. Safe use of AGV lithium battery pack 1. The reason why AGV trolleys can work for 24 hours is mainly driven by lithium batteries. Many companies always ignore its safety issues when using AGV trolleys, and not every machine will be supervised at work. Once some safety accidents occur in the lithium battery of AGV trolleys, it will be harmful to the workplace where the AGV trolley is located. Cause a lot of hidden dangers. 2. The safety hazard of AGV lithium battery trolley mainly comes from the power source in its body-lithium battery. Due to the unstable characteristics of lithium battery, there are many places to pay attention to. For example, do not over discharge, do not disassemble at will, etc. If any abnormal battery has serious deformation, peculiar smell, liquid leakage, or unexplained noise, stop using it immediately. 3. The external environment is also a major reason for the safety of the AGV lithium battery trolley. The AGV needs to be protected from direct sunlight, dry and ventilated, and there is no heat source nearby when working or storing it. When transporting, loading and unloading lithium batteries, be careful not to fall, heavy pressure and other accidents; after 12 hours of continuous charging, the charger does not change the light or the surface becomes hot and needs to stop charging immediately. 4. If the AGV lithium battery car that has been idle for a long time finds that the battery cannot be charged, it should start to operate at a slow speed without load for a while, and then go to the battery to charge the car after it is hot. Drained batteries and lithium batteries should be charged immediately. Prolonged time will destroy the batteries, and the number cannot be delayed for up to 24 hours. AGV lithium battery as the main power source is the 'heart' of AGV trolley. However, this 'heart' has certain safety hazards, which may cause dangerous explosion accidents of the battery due to its own or external factors. AGV lithium battery trolleys have greatly improved the efficiency of these industries with automated and intelligent technology and management levels, and they must be vigilant in their daily use.
