Excavator:
Diesel Consumption vs. Electric Consumption
Diesel Consumption:
Fuel Cost: Diesel engines require regular refuelling, which involves significant ongoing costs for fuel.
Efficiency: Diesel engines typically have lower efficiency compared to electric motors. A substantial amount of energy is lost as heat.
Maintenance: Diesel engines require regular maintenance such as oil changes, filter replacements, and more frequent servicing due to the higher number of moving parts.
Electric Consumption:
Energy Cost: Electricity is generally cheaper than diesel fuel, leading to lower operating costs.
Efficiency: Electric motors convert a higher percentage of electrical energy into mechanical energy, with less energy lost as heat.
Maintenance: Electric motors require less maintenance due to fewer moving parts, leading to reduced service costs and less downtime.
Comparative Analysis To provide a detailed comparison, let’s consider a hypothetical scenario where we compare the diesel and electric consumption for a Tata Hitachi 200 excavator:
Diesel Engine:
Fuel Consumption Rate: Approximately 15-20 liters per hour (we will use 15 liters per hour for this calculation).
Fuel Cost: ₹92 per liter. Hourly
Fuel Cost: 15 liters/hour * ₹92/liter = ₹1,380 per hour.
Electric Motor:
Energy Consumption Rate: 90 kW per hour.
Electricity Cost: ₹7 per kWh. Hourly
Energy Cost: 90 kWh * ₹7/kWh = ₹630 per hour.
Cost Savings:
Hourly Savings=Diesel Hourly Cost−Electric Hourly Cost
=₹1,380−₹630 = ₹750 per hour = 54.35%
Summary
The electrification of heavy machinery like the Tata Hitachi 200 and loaders offers substantial economic and environmental benefits. By converting to electric motors, operators can achieve significant cost savings, improved efficiency, reduced maintenance, and a reduced carbon footprint. The example above illustrates the potential hourly savings, emphasizing the financial advantages of switching from diesel to electric power.
