AI Technical Summary

Problems solved by technology

[0004] The quality of the technical state of the battery pole directly affects the release and storage of battery electric energy. Due to the harsh working environment, the battery pole will have damage, oxidation, corrosion, pantothenic acid, or burnt failures caused by internal or external factors. The battery storage path is not smooth, which leads to insufficient electric energy storage and lower no-load voltage. In addition, the blockage or blockage of the electric energy release path increases the internal resistance of the battery itself, so that its function cannot be exerted, which in turn leads to power consumption. The equipment cannot work normally. When the battery is used as the starting power supply, the technical state of its pole is not good, which not only affects the function of vehicles, construction machinery and other equipment, but sometimes vehicles, construction machinery and other equipment will lose power if they are turned off when they are in a dangerous situation. If they cannot be started in time Escape, which will endanger the safety of personnel and equipment

[0005] Oxidation, corrosion, and pantothenic acid on the surface of the battery pole will also increase the contact resistance between the pole itself and the terminal connected to it. The contact resistance formed here will form a voltage drop, which will cause the battery charging terminal voltage to increase. If the battery becomes low, the battery will be insufficiently charged. If things continue to make ends meet, the battery plate will be vulcanized, and the plate vulcanization will cause the internal resistance of the battery power supply to increase. The longer the power consumption time, the lower the output voltage of the battery, which will cause long-term deep discharge of the battery and further lead to deep vulcanization of the plate, which will cause the battery to be scrapped prematurely before the design life, thereby shortening the battery production cycle and indirectly wasting resources and resources. energy

[0006] Once the surface of the battery pole is slightly oxidized, corroded, or pantothenic acid, the resistance between the surface and the terminal will cause resistance heat when a large current passes through, and the temperature rise caused by the heat will make the lead bushing of the pole and its plastic seal The structure melts, which aggravates the corrosion of the pole. This vicious cycle will make the pole damage more serious until the battery cannot be used; sometimes there is a virtual connection between the pole and the terminal. Sparks caused by arcing between the connecting terminals will also cause explosion accidents of the battery case

[0007] Poor technical condition of battery poles will not only lead to the above-mentioned hazards caused by the electric energy of the battery not coming out, but also affect the electronic equipment of the body and the electronic control equipment of the engine. The battery is connected in parallel between the generator and the electrical equipment. It has the function of voltage stabilization. While the battery is used as the charging load of the generator, it is also a power filter. The positive and negative plates of the battery itself are a filter capacitor, which can suppress or filter out the surge pulse of the generator power system and reduce the peak voltage of the power supply. Harm to electronic equipment, the contact resistance between the battery pole and the terminal and the vehicle power supply caused by the corrosion of pantothenic acid is sometimes unstable, and the connection between the pole and the external circuit is sometimes good or bad, and it seems to be connected but not connected. The internal resistance of the battery is high for hours, which leads to the instability of the voltage of the entire power system. If the contact resistance between the pole and the terminal suddenly becomes infinite, this is equivalent to the instantaneous unloading of the generator, which causes the voltage of the entire power system to rise instantaneously. It will cause damage to vehicle electronic equipment, driving computer, and body computer, and the filament will suddenly blow out when driving at night, causing safety accidents

[0008] In the use of lead-acid batteries, it is easy to damage the battery poles in various situations, and the damage reasons are also various, such as the lack of materials on the surface of the poles caused by flaws, deformation, direct short circuit between the positive and negative poles caused by human factors Physical damage such as damage, and chemical deterioration caused by oxidation, corrosion, and pantothenic acid on the outer surface of the pole make it unable to connect normally with the battery terminal. Such situations are common in daily maintenance practice and are universal. The harm caused by the failure of the pole ranges from delays in time and work to accidents, and in serious cases, endangers the safety of people and equipment. If it cannot be repaired safely, the only way to replace it is with a new battery. If the pole is damaged and scrapped, it will inevitably lead to a large number of batteries entering the reproduction cycle, which will inevitably directly cause a waste of energy resources. Safe and reliable restoration has important practical significance
