Energy Consumption and Cutting Performance of Battery-Powered Chainsaws

The aim of this research is to measure the energy consumption and compare cutting performance three types battery-powered chainsaws (Stihl MSA 200, Stihl 220, 300). Tested were powered by two different battery packs AP 300 S 500 S) with capacity output current when wooden beams, European beech (Fagus sylvatica L.) black locust (Robinia pseudoacacia densities moisture content. Energy was measured using a multimeter built-in charger housing, consumed noted in watt-hours. Each individual cut recorded an action camera at 60 frames per second, duration cuts centiseconds observed on obtained recordings. Results show significant differences between chainsaw/battery combinations. ranged from 2.45 4.50 Wh for MSA300E_AP500S MSA220_AP300S, respectively) 3.10 5.00 MSA300M_AP500S MSA220_AP500S, respectively).

However, if there increase coming times, will certainly displace petrol use future.
