It has a massive battery pack of 300 kWh, which they designed to withstand a lot of rough movement. At 3.4 tons, the result is a fairly heavy pack. They believe that the battery can be used for anywhere from five to seven hours before it needs to be charged, which can be done overnight.
At 65% load, the machine runs for nine hours. It takes about ten hours to fully charge from zero using a standard 220 V power outlet. In the past two years, a number of OEMs, including Volvo, Komatsu, Bobcat, Kato, Hyundai, and JCB, have introduced electric excavator technology.
Even though the hydraulic pumps can be heard, the excavator’s powertrain also includes a 122 kW electric motor that operates almost silently. This is the very first time a 26-ton excavator has been converted to battery power. By reducing air and noise pollution at construction sites, the machine will improve employee experiences.
The Global electric excavator battery market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2023 to 2030.
The recently launched brand-new electric 20-ton machine from Komatsu has a battery capacity of 451 kWh and a power output of 123 kilowatt-hours. That contrasts with Caterpillar’s January 2019 announcement that it was building the “world’s largest” excavator: a 26-ton machine with a battery pack of 300 kWh.)
In the proof-of-concept tests that were carried out on advanced research machines at customer construction sites, the Proterra battery system of the new electric excavator was able to operate for anywhere from five to nine hours when it was fully charged. The hydraulic pump, controller, and electric motor that power the work equipment are all parts of the Komatsu machine.
The additional benefit of electrifying construction equipment is that it can be utilized for work in urban areas and at night without generating emissions or noise pollution. “The zero engine vibration will also help reduce operator fatigue,” according to Komatsu.
