AGV lithium battery pack common failures, AGV lithium battery pack safe use method. With the gradual high temperature in summer, the frequency of problems with AGV lithium batteries is increasing, in fact, AGV users on the one hand care about the life of lithium batteries, but on the other hand, but not the correct use, then the good battery can not withstand the torment. The following Cunningham electrical small to explain the common failures of AGV lithium battery pack and AGV lithium battery pack safety use.
AGV lithium battery pack common failures
① battery explosion: the sub-volume cabinet has a common fault, diaphragm closure utility is poor, internal short-circuit fault.
② low battery power: cause: the amount of attached material is low, the amount of attached material on both sides of the pole piece is very far apart, less lithium battery electrolyte, lithium battery electrolyte redox potential is low, the diaphragm porosity is small, the volume of the core is not filled with electricity when the ultra-thick partition capacity, the positive battery positive material than the volume is small.
③ high resistance within the rechargeable battery: cause: cathode lug and lug false connection, positive level lug and lug false connection, positive level lug and basket false connection, cathode lug and shell false connection, bolt and bender touching the internal resistance, positive level did not add conductive agent, lithium battery electrolyte without lithium salt, rechargeable battery previously produced short-circuit fault, diaphragm paper porosity is small.
④ low working voltage of rechargeable battery: lithium battery pack electrolyte decomposed off, positive level has residue, water, customer's pcb circuit board go electric, customer did not touch welding as required, vibration pattern, micro short circuit fault, cathode caused dendrite.
AGV lithium battery pack safety use method
1, AGV trolley can work 24 hours a day, mainly by which the lithium battery as power. Many companies in the use of AGV trolley will always ignore its safety issues, and not every machine at work will be supervised, once the AGV trolley lithium battery some safety accidents, will cause great danger to the entire AGV trolley in the workplace.
2, AGV lithium battery car safety hazards mainly from its body power source - lithium batteries, due to the unstable nature of lithium batteries, so there are many places that need attention. For example, can not be over-discharged, do not disassemble at will, etc., found any abnormal battery has serious deformation, odor, leakage, unexplained sound to immediately stop using.
3, the external environment is also a major reason for the safety of AGV lithium battery cart, AGV at work or storage needs to be in a place where there is avoid direct sunlight, dry and ventilated, no heat source nearby. In the transport loading and unloading lithium batteries should 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 is hot need to immediately stop charging.
4, long-term idle AGV lithium battery car if you find that you can not charge the battery should be started without load slow speed operation for a while, both warm up the car and then go to the battery charging. Drain the battery and lithium battery should be immediately battery charging, drag time will destroy the battery, the number can not be delayed for up to 24 hours.
AGV lithium battery as the main power energy is the "heart" of the AGV trolley, but this "heart" has certain safety risks, will cause dangerous battery explosion due to their own or external factors. Intelligent technology and management level so that these industry sectors in the work of a great improvement in efficiency, daily vigilance to use.
