The battery is the energy source of
the AGV car
and is also related to the lifespan of the AGV car. AGV
Autonomous guided vehicles
Several commonly used batteries are:
Nickel-cadmium batteries
,
Nickel-metal hydride batteries, lithium batteries and lead-acid batteries, etc.
How to choose the power supply of AGV car?
Approximately 50%
The continuous current of the AGV is 20 A, so a battery with a capacity of 40 Ah can provide the AGV car about 2 hours battery life. p>
Several types of batteries commonly used in AGV unmanned vehicles are: nickel-cadmium batteries, nickel-metal hydride batteries, lithium batteries, and lead-acid batteries
< p>When choosing the AGV batteries, we can start from the communication characteristics of the battery. Specifications and mBattery models are determined by careful consideration of protocol, voltage, weight, operating environment temperature, safety and lifespan.1: AGV trolley nickel-cadmium battery
The internal resistance is large and can be discharged with a large current. The voltage change during discharge is small compared to other types of batteries. Nickel cadmium batteries can withstand overcharge or discharge, simple and convenient operation. The discharge voltage varies depending on the discharge current. Generally speaking, it is about 1.2 V. The end-of-discharge voltage of the nickel-cadmium battery is 1.0 V/CELL. Actual operating temperature range is -20 degrees to 60 degrees. Discharge should be carried out within this range, and charging and discharging can be repeated more than 500 times.
2: Nickel-metal hydride car batteryure AGV
The energy of nickel-metal hydride battery is twice that of nickel-cadmium battery. It can be charged quickly in an hour with one. special charger. The self-discharge characteristics are better than nickel-cadmium batteries, can be kept longer after charging, and can be repeatedly charged and discharged more than 500 times
3: AGV. car lithium battery
It has high energy density. Compared with high-capacity nickel-cadmium batteries, the energy density is 1.5 times, the energy density is 2 times, high voltage, the average operating voltage is 3.6V, 3 times that of nickel-cadmium batteries cadmium and nickel-metal hydride batteries, and the operating voltage is flat. It also has high capacity, wide operating temperature range from -20 degrees to 60 degrees and long charge and discharge life. After 500 diceloads, its capacity is always at least 70%. Because lithium batteries have the characteristics of high energy density, high voltage and stable operation.
4: AGV Car Lead Acid Battery
Lead acid battery is the most widely used battery. It uses sponge lead as the negative electrode and lead dioxide as the positive electrode. Use These two substances are called active substances and an aqueous solution of sulfuric acid is used as the electrolyte. They jointly participate in the electrochemical reaction of the battery. Lead-acid batteries have good reversibility, stable voltage characteristics, long service life, wide application range, abundant raw materials, renewable use and low cost. Mainly used in various fields of the national economy such as transportation, mining, ports, national defensee, computing, scientific research, etc., it constitutes an important part of social production, business activities and human life.An indispensable product in life.
