The battery of AGV determines the power and overall performance of AGV. What are the batteries of AGV? Here are some common AGV batteries for AGV transport vehicles: nickel-cadmium batteries, : rgb(255, 255, 255);">Lead-acid batteries,NiMH batteries and lithium batteries, etc., their related characteristics are introduced below.
1. Nickel-cadmium battery
The positive electrode active material is mainly made of nickel, and the negative electrode active material is mainly made of cadmium. Battery.
Used for The nickel-cadmium battery of the AGV has a large internal resistance and can discharge with a large current, with a small voltage change during discharge. Compared with other types of batteries, nickel-cadmium batteries can withstand overcharge or discharge, and are simple and convenient to operate. The discharge voltage varies according to the discharge current, generally around 1.2V. The discharge termination voltage of nickel-cadmium batteries is 1.0V. /CELL, the practical operating temperature range is -20 degrees to 60 degrees. Discharge can be repeated more than 500 times within this range.
2. Nickel-metal hydride battery
The positive electrode active material is mainly made of nickel, and the negative electrode active material is mainly made of a hydrogen storage alloy. Alkaline storage battery.
NiMH batteries are improved from NiCd batteries. They provide higher capacity, less obvious memory effect, and lower environmental pollution than NiCd batteries at the same price. They can be charged with a special charger. It can be quickly charged in one hour, and its self-discharge characteristics are better than those of nickel-cadmium batteries. It can be retained for a longer time after charging, and can be charged and discharged repeatedly for more than 500 times.
3. Lead-acid battery
A battery in which the electrodes are mainly made of lead and its oxides, and the electrolyte is a sulfuric acid solution.
AGV lead-acid battery is the most widely used battery. Lead-acid battery has good reversibility, stable voltage characteristics, long service life, wide application range, rich raw materials, and renewable use and Advantages such as low cost.
4. Lithium battery
"Lithium battery" is a type of battery made of lithium metal or lithium alloy and using non-aqueous electrolyte solution.
a. High energy density. Compared with high-capacity nickel-cadmium batteries, the energy density is twice that of them. b. High voltage, the average operating voltage is 3.6V or 3.2V, which is three times that of nickel-cadmium batteries and nickel-hydrogen batteries. The operating voltage is flat and the capacity is high, the wide operating temperature is -20 degrees to 60 degrees, the charging and discharging life is long, and the capacity is at least 70% after 100 discharges. c. Environmental protection. Lithium batteries are pollution-free batteries. d. Light weight. Based on the above points, lithium batteries are becoming more and more popular with agv manufacturers and users!
The above are the relevant characteristics of the commonly used batteries for agv vehicles. Due to the obvious advantages of lithium batteries, agv lithium batteries will become the standard configuration of agv moving vehicles.
Jinchi Technology focuses on AGV car lithium batteries. Its main products are lithium iron phosphate batteries and ternary lithium batteries. Professional matters are left to professionals!
