Hybrid, including hybrid and hybrid. Hybrid oil and electricity, especially in the automotive field has been a lot of use, in the field of construction machinery, especially excavators, also has many years of research and development. Common brands of excavators or loaders adopt the way of hybrid oil and electricity. Experts believe that the energy density of oil electric hybrid is high, but the power density is low. The obvious advantage of oil electric hybrid is its high power density. Power density refers to the ability of energy storage unit to provide instantaneous power per unit mass. This has more obvious energy-saving advantages for the construction machinery with frequent starting, braking and turning, and has a broad prospect in the future construction machinery hybrid power developers.
