As electrification becomes the mainstream trend of modern material handling equipment, reasonable fleet design of electric forklifts has become a core factor affecting the overall operation efficiency and cost control of warehouse, manufacturing and logistics scenarios. Many operation teams often ignore the matching relationship between fleet configuration and actual shift arrangement, leading to either excessive idle of equipment resources or insufficient operation capacity during peak periods, which brings unnecessary extra cost.

For single-shift operation scenarios that maintain 6 to 8 hours of daily working time with average load rate below 60%, the fleet design can follow a relatively lean configuration logic. The core configuration of the fleet does not need to select oversized battery packs, and the standard capacity battery that can cover the full shift work without midway charging is enough. Each forklift can be equipped with a standard on-board slow charger, no extra spare battery or special centralized charging station is required. The reserved redundancy of fleet number can be controlled at about 10% based on the maximum peak daily operation demand, and the daily maintenance only needs to carry out routine inspection once a week, no special full-time maintenance personnel on site is required.

For multi-shift operation scenarios that run 16 to 24 hours a day with average load rate above 85%, the fleet design needs to reserve more supporting space to ensure continuous operation. Each forklift unit is recommended to be equipped with at least one spare battery that supports fast energy supplement, and the site needs to set up a special ventilated centralized charging area with matching protection facilities. The battery pack should choose products with higher cycle life to adapt to frequent charging and discharging cycles every day. The reserved redundancy of fleet scale can be controlled at 20% of the peak demand, and full-time inspectors should be arranged to carry out status check for each shift, to eliminate potential equipment faults before they affect normal operation.

From the perspective of full lifecycle cost within 5 years, the initial input of a reasonably designed single-shift electric forklift fleet is about 30% to 35% lower than that of the same number of units designed for multi-shift scenarios, and the annual operation and maintenance cost including power consumption, maintenance and parts replacement is also significantly lower. For multi-shift scenarios, though the initial input is higher, its unit operation hour cost is far lower than that of traditional internal combustion forklifts, considering the savings in fuel cost, carbon emission related expenses and daily energy consumption.

Operation teams can make targeted fleet design according to their own actual daily operation hours, peak operation fluctuation and on-site charging condition, to avoid unreasonable configuration that causes resource waste or operation interruption, and finally realize the balance between sufficient operation capacity and controllable full cycle cost.
