In the logistics and transportation industry, the safe and reliable unmanned AGV is widely used in factory processing systems and has many advantages such as low noise, low pollution, intelligent program control, and efficient handling. The principle of the AGV trolley is a transport vehicle equipped with electromagnetic or optical automatic guidance devices, capable of traveling along a prescribed guidance path, safety protection and various moving and carrying functions. A professional technician issues an instruction to the computer program, and this instruction is finally accepted and executed by the AGV-sending the auxiliary materials to the designated corresponding location. Convenient and fast to reduce floor space and manual workload.
The driving mechanism is an important part of the AGV, and currently most of them use battery power supply as the power source for operation. Then the power supply, discharge, and charge of the battery in the entire system are particularly important.
When the power of the AGV trolley is about to run out to reach the set value range, it will send a request command to the system to request charging, and automatically go to the charging place after the system allows it to be charged in sequence.
Choosing the right AGV battery is of great significance to the operation of the trolley. A battery with good performance can effectively reduce the size and weight of the AGV, and it also has a direct impact on the working time of the AGV. The characteristics of the battery have a great influence on the system design of the AGV. At present, several types of batteries commonly used in AGV unmanned vehicles are: lead-acid batteries, nickel-cadmium batteries, lithium batteries, etc. Among them, the lithium battery has an intelligent control board, high energy density, high voltage, and supports high-current fast charging. It can be set more The charging and discharging mode of the program, clean and environmental protection and other stable work characteristics, have been widely used in the AGV industry.
In the AGV industry, Hawke lithium battery has many successful cases of application in the AGV industry field. The product technology has been applied and promoted by many manufacturers in the industry. The following takes Hawke lithium battery as an example to introduce several charging conditions of lithium batteries:
The lithium battery is charged online during the charging process, that is, the AGV trolley does not leave the working line, and no special time is required for charging. Instead, it uses the short dwell time during work to charge. This charging method that fully utilizes fragmented time and does not take up working time is actually an extension of random charging. It just embeds the charging station into the workflow of the AGV to further improve the efficiency of the AGV.
The offline charging of the lithium battery means that the AGV exits the service and drives into the charging area or a special charging station to use a portable Hawker industrial charger for charging.
AGV battery performance directly affects the life of AGV trolleys. As the energy source of AGV trolleys, the performance of the battery directly affects whether the AGV can operate stably, efficiently and reliably, and it is also related to the service life of AGV trolleys.
