BATTERY ELECTRIC EXCAVATOR - A simplified explanation of the abstract
This abstract first appeared for US patent application 18526037 titled 'BATTERY ELECTRIC EXCAVATOR
The abstract describes a battery-powered electric excavator with an undercarriage, main frame, operator's cabin, high voltage battery, primary electric motor, main hydraulic pump, and hydraulic reservoir.
- The excavator has left and right crawler tracks on the undercarriage.
- The main frame can pivot vertically relative to the undercarriage.
- The operator's cabin is closer to the forward end and to one side of the vertical pivot axis.
- At least one high voltage battery is located behind the vertical pivot axis and the operator's cabin.
- A primary electric motor is connected to the high voltage battery.
- The primary electric motor drives at least one main hydraulic pump.
- The primary electric motor, main hydraulic pump, and hydraulic reservoir are located on the main frame on the opposite side of the vertical pivot axis from the operator's cabin.
Potential Applications: - Construction industry for excavation and earthmoving tasks. - Mining industry for digging and transporting materials. - Agriculture for land preparation and irrigation projects.
Problems Solved: - Reduces reliance on fossil fuels. - Provides a more environmentally friendly option for heavy machinery. - Increases efficiency and precision in excavation tasks.
Benefits: - Lower operating costs due to the use of electric power. - Reduced emissions and carbon footprint. - Improved maneuverability and control.
Commercial Applications: Electric excavators can be used in construction projects, mining operations, and agricultural activities. The market for electric construction equipment is growing as companies seek more sustainable and efficient solutions for their operations.
Questions about Electric Excavators: 1. How does the use of high voltage batteries impact the performance of the excavator? 2. What are the potential challenges in integrating electric motors into heavy machinery like excavators?
Original Abstract Submitted
A battery powered electric excavator includes an undercarriage including left and right crawler tracks. A main frame is mounted on the undercarriage to be pivotable about a vertical pivot axis relative to the undercarriage. An operator's cabin is located on the main frame closer to the forward end than to the rearward end and located to one lateral side of the vertical pivot axis. At least one high voltage battery is located on the main frame rearward of the vertical pivot axis and rearward of the operator's cabin. A primary electric motor is operably connected to the at least one high voltage battery. At least one main hydraulic pump is driven by the primary electric motor. The primary electric motor, the main hydraulic pump, and a hydraulic reservoir are located on the main frame on an opposite lateral side of the vertical pivot axis from the operator's cabin.
