Take Control of Forklift Energy Costs With an Informed Power Strategy
Forklift power is often treated as a fixed operating expense, but it can also be a source of smarter energy planning and cost control.
With the right information, you can get a clearer picture of how power is used and where unnecessary energy use may be adding cost. That means looking beyond the lift truck or battery alone and considering the entire power ecosystem: batteries, chargers, charging practices, infrastructure, utility rates and shift schedules.
Balancing Battery Efficiency
Battery choice has a big effect on how efficiently energy is stored and used. Lead-acid batteries remain a practical option in the right applications, especially when usage patterns are predictable and battery maintenance is consistent.
Lithium-ion batteries, such as V-Force® integrated lithium-ion systems, can offer another path. They draw more grid power due to faster charge cycles but consume about 16 percent less energy overall. Because lithium-ion batteries support opportunity charging, operators can plug in during normal breaks and keep lift trucks moving with less downtime. Lithium-ion batteries also eliminate the need for centralized battery rooms, spare batteries, long charge cycles and cool-down periods.
The ROI case for lithium-ion can be especially strong in high-throughput, multi-shift operations that rely on frequent battery changes. In many facilities, however, the right approach depends on duty cycle, charging behavior, maintenance capacity and infrastructure. In some cases, those factors may make a mixed battery strategy the best fit.
Charger Upgrades Can Offer Energy Savings
If you’re looking for a practical first step, start with your chargers. Charger efficiency has improved significantly over the past 15 to 20 years. Modern high-frequency chargers, such as Crown’s V-Force V-HFM3 charger, can reach up to 97 percent efficiency.
Older chargers may waste as much as half of the power they draw from the grid during the charging cycle. Upgrading charger technology can create meaningful savings, even before making larger changes to batteries or infrastructure.
Check Your Utility Bill
Your utility bill can also offer valuable clues. Two facilities with similar charging habits may incur very different energy costs based on their local rate structures.
Look closely for peak-demand charges and time-of-use pricing. In many areas, demand charges are tied to peak usage periods, which can shift by utility, region, season and time of day. Once you know when those periods occur, you may be able to adjust charging schedules to avoid the most expensive periods without disrupting operations.
Use Programmable Charging Controls
Avoiding peak-demand charges doesn’t always mean shutting down charging completely during peak periods. In a multi-shift operation, the goal is usually to manage charging more intelligently.
For example, if peak pricing runs from 4 to 9 p.m., a facility running a second shift might limit how many lift trucks charge during that period. Advanced demand response systems, including the Demand Response Management feature available on Crown’s V-Force V-HFM3 connected charger, can help automate these decisions. Chargers can be grouped and programmed around spot pricing, target peak loads, infrastructure limits and other factors that affect energy cost.
Connect the Teams That Shape Energy Decisions
Energy management should also be collaborative. Utility bills show cost-per-kWh rates and peak-demand periods. Facilities teams understand electrical capacity. Operators see when trucks are being plugged in outside recommended charging times. Fleet managers know what equipment must be ready for each shift.
A power study can bring these perspectives together, helping you identify where changes make sense and make informed decisions about charging practices, energy use and infrastructure needs. This broader view can help reduce your total cost of ownership and potentially delay or avoid costly infrastructure upgrades.
Smart Warehousing Includes Smarter Energy Decisions
Energy volatility is likely to continue, but warehouse operations can gain more control. By treating forklift power as a connected, data-informed system, you can reduce waste and manage costs more efficiently.
A smarter power strategy starts with understanding the full picture: batteries, chargers, power usage, utility rate structures and the operational demands of your facility.
