Battery is the energy source of AGV car, and also relates to the service life of AGV car.Common battery types for AGV vehicles include nickel-cadmium battery, nickel-metal hydride battery, lithium battery and lead-acid battery, which have the following characteristics:
The nickel-cadmium battery used in AGV car has large internal resistance and can be used for large current discharge.
2. Nimh battery
It offers higher capacity at the same price as nickel-cadmium batteries, less pronounced memory effects, and lower environmental pollution.
3. Lithium battery
"Lithium battery" is a kind of battery with lithium metal or lithium alloy as negative electrode material and non-aqueous electrolyte solution. Because lithium battery has the characteristics of high energy density, high voltage and stable operation, it is widely used.
4, lead acid battery
The electrodes are mainly made of lead and its oxides, and the electrolyte is a kind of battery with sulfuric acid solution.Lead-acid battery has the advantages of good invertibility, stable voltage characteristics, long service life, wide application range, abundant raw materials, renewable use and low cost.
