LFP Battery Pack for Electric Wheel Loader

Heavy-Duty Battery Solution for Construction Equipment

We developed a 76.8V 280Ah (21.5kWh) LiFePO4 battery pack for an electric wheel loader operating at a concrete batching plant.

The equipment operates approximately 20 hours per day in a demanding environment with heavy dust, vibration, temperature fluctuations, and frequent high-power loading and lifting operations.

Battery Solution

• 76.8V 280Ah / 21.5kWh LiFePO4
• 280A continuous / 420A peak discharge
• Fast charging: 20–100% in approx. 1 hour
• Intelligent BMS with RS485 communication
• Liquid cooling for thermal management
• IP65 protection and reinforced steel enclosure
• Operating temperature: -20°C to +55°C
• Cycle life: ≥4,000 cycles

Field Results

The battery system has accumulated more than 10,000 operating hours without a battery-related failure.

The electric wheel loader achieves approximately 6 hours of continuous heavy-duty operation on a full charge.

Compared with a diesel-powered machine under similar conditions:

• Electricity cost: ~RMB 400/day
• Diesel fuel cost: ~RMB 1,400/day
• Energy cost saving: ~RMB 1,000/day per machine

The solution also delivers zero tailpipe emissions, significantly lower noise, and reduced engine maintenance requirements.

Reliable Power for Heavy-Duty Equipment

This project demonstrates how a customized LFP battery system can replace diesel power in demanding construction applications while delivering lower operating costs, reduced maintenance, and reliable long-term performance.
