Daily Power Consumption Calculation for Fully Electric Self-loading Stacker

Small business owners and medium-sized factories adopt fully electric self-loading stackers to replace exhausting manual cargo handling. Before purchasing, calculating daily power expenditure prevents unexpected over-budget operation costs.

Power Calculation Formula

Battery energy (kWh) = Voltage (V) × Capacity (Ah) ÷ 1000 All self-loading stackers adopt 48V lithium batteries with three mainstream specs:

48V40Ah (500kg semi-electric model): 48×40÷1000 = 1.92 kWh

48V60Ah (700kg–1t fully electric bestseller): 48×60÷1000 = 2.88 kWh

48V80Ah (1.2–1.5t heavy-duty model): 48×80÷1000 = 3.84 kWh

Theoretical full-charge capacity ≠ actual daily consumption. Around 10% energy loss comes from wiring resistance, standby power and charge-discharge attenuation. Actual power consumption = Total battery capacity × Daily discharge ratio × 1.1 loss factor

Example: 48V60Ah 1-ton Fully Electric Self-loading Stacker

Total battery energy: 2.88 kWh; 85% fully discharged under all-day frequent heavy unloading Actual consumption = 2.88 × 0.85 × 1.1 ≈ 2.7 kWh per day

Daily Power Breakdown

Climbing up & down truck beds (45%): Highest power draw due to peak motor load under heavy load. 15 daily trips consume ~1.22 kWh

Fork lifting & lowering during loading/unloading (30%): Repeated pallet lifting uses ~0.81 kWh

Short-distance flat ground transit (20%): Low-speed travel consumes ~0.54 kWh

Standby & circuit energy loss (5%): Waiting idle plus battery conversion loss ~0.13 kWh

Power Consumption for Other Models

500kg semi-electric model: No travel motor, power only for lifting & climbing; 1.8–2 kWh daily for frequent unloading

1.5t heavy-duty model: Higher load for climbing and lifting; 3.4–3.8 kWh daily under continuous heavy work

Key Factors That Influence Power Draw

Frequent heavy lifting and repeated truck climbing drastically raise electricity usage

Smooth constant-speed operation, low-fork transit and less idle lifting effectively save power

Original factory lithium batteries feature higher energy conversion efficiency and lower power consumption than cheap refitted third-party batteries
