The Benefits of Electric Forklifts: Emissions, Noise, and Maintenance Savings
As a seasoned industry expert in forklifts, warehousing, and logistics, I’ve seen firsthand the transformative impact of electric forklift technology. Gone are the days when internal combustion engine (ICE) forklifts dominated the materials handling landscape. Today, electric forklifts comprise a staggering 64% of the North American lift truck market, according to the Industrial Truck Association (ITA).
The shift towards electric power offers a myriad of advantages that are simply too compelling to ignore. One of the most significant benefits is the complete lack of direct emissions from electric forklifts. This is particularly crucial for indoor operations in warehouses, distribution centers, and manufacturing facilities, where exposure to the toxic fumes of gas, diesel, or propane-powered forklifts can pose serious health risks for workers. By eliminating these harmful emissions, electric forklifts create a cleaner, greener, and safer work environment, helping facilities comply with OSHA regulations and avoid costly ventilation upgrades.
Moreover, electric forklifts are substantially quieter than their ICE counterparts. While ICE forklifts can reach noise levels of 80-90 decibels (dBA), equivalent to a gas-powered lawnmower, electric forklifts typically operate at just 60-70 dBA. This 20-30 dBA reduction makes a significant difference in worker comfort, safety, and productivity, reducing the need for hearing protection and improving communication on the job site.
In addition to the environmental and ergonomic benefits, electric forklifts also offer significant maintenance cost savings. With fewer moving parts and no internal combustion engine, electric forklifts require far less maintenance than their ICE counterparts. This translates to lower repair and servicing expenses, allowing companies to allocate those resources towards other operational priorities.
Charging Strategies for Electric Forklift Fleets
As more companies commit to transitioning their forklift fleets to electric power, the need for reliable and efficient charging infrastructure becomes paramount. Fortunately, there are two primary options for charging electric forklifts: Level 2 AC chargers and DC fast chargers.
Level 2 AC Chargers: Overnight Recharging for Standard Shifts
Level 2 AC chargers, also known as “plug-in” chargers, are a popular choice for electric forklift fleets operating on a standard eight-hour shift. These chargers provide between 6-10 kW of power, allowing forklifts to fully recharge their batteries overnight when not in use. With the ability to replenish 20-25 miles of range per hour of charging, Level 2 chargers offer a certified, reliable solution that is backed by the California Type Evaluation Program (CTEP).
The installation of Level 2 chargers typically carries lower equipment costs compared to DC fast charging stations, making them a cost-effective option for many facilities. However, in high-demand, fast-paced environments where multiple forklifts need to operate on more than a single eight-hour shift, the slower charging times of Level 2 chargers may pose a detriment to maintaining sufficient battery levels for production demands.
DC Fast Chargers: Rapid Refueling for Continuous Operations
For facilities with electric forklift fleets that run extended shifts around the clock, DC fast chargers offer a compelling solution. By providing direct current (DC) power to the battery pack, these chargers can restore up to 80% of a forklift’s battery capacity in just 1-2 hours, depending on the charge rate. The higher the kW rating of the DC fast charger, the quicker the charge time.
DC fast chargers from BTC POWER, ranging from 120 kW to 180 kW, are designed to rapidly fuel up fleets and return equipment to service in the warehouse, factory, or dock. These high-powered chargers require more substantial facility preparation, including the installation of a transformer and appropriate electrical connections, but they provide the best option for operations that demand continuous uptime and cannot afford lengthy charging downtimes.
Optimizing Charging Infrastructure and Battery Swapping
Regardless of whether a facility chooses to install Level 2 or DC fast chargers, there are several key factors to consider when outfitting an electric forklift fleet:
-
Charger Placement: Chargers should be strategically placed in locations that are convenient for operators to access, particularly if the facility employs an “opportunity charging” strategy, where forklifts are topped up during breaks or downtime.
-
Charging Times: Charging times vary based on the charger type, battery type, and size. Lithium-ion batteries generally offer faster recharging times compared to lead-acid batteries, with some lithium-ion forklifts capable of fully charging in under an hour.
-
Operator Training: OSHA requires that only trained personnel be permitted to charge and change batteries in electric forklifts. While lithium-ion batteries have a simpler charging protocol, as they do not need to be removed from the truck, proper training is still essential.
-
High-Voltage Safety: High-capacity electric forklifts may use high-voltage systems, and facilities must understand and adhere to the relevant safety standards to prevent electrical hazards and injuries.
-
Contingency Planning: Having a plan in place to mitigate equipment downtime in the event of a power outage or other disruption is crucial. This may involve maintaining a fleet of ICE rental forklifts or exploring alternative power sources, such as hydrogen fuel cells.
By carefully considering these factors and developing a comprehensive charging strategy that meets the specific needs of their electric forklift fleet, companies can maximize the efficiency, cost-savings, and sustainability benefits of their electrification efforts.
Navigating the Transition to Electric Forklifts
While the initial acquisition cost of electric forklifts may be higher than their ICE counterparts, the long-term savings and performance advantages can make the switch a wise investment. Factors such as reduced operating and maintenance expenses, extended equipment life, and various state and federal incentive programs can all contribute to a lower total cost of ownership (TCO).

Their team of experts, including an extensive network of dealers, is ready to guide companies through the process, helping them harness the benefits of clean power and electrification.
By working closely with industry leaders and leveraging the latest charging technologies, companies can navigate the transition to electric forklifts with confidence, optimizing their battery swapping and charging infrastructure to drive a more sustainable, efficient, and productive materials handling operation.
Conclusion
The future of forklift fleets is undoubtedly electric. As the industry continues to embrace the advantages of zero-emission, quiet, and low-maintenance electric forklifts, the importance of implementing the right charging infrastructure becomes increasingly crucial.
Whether you choose to deploy Level 2 AC chargers for standard eight-hour shifts or invest in high-powered DC fast chargers for round-the-clock operations, the key is to develop a comprehensive charging strategy that meets the unique needs of your facility and materials handling requirements.
By optimizing your battery swapping and charging infrastructure, you can unlock the full potential of electric forklifts, driving cost savings, enhancing worker safety and well-being, and contributing to a more sustainable, environmentally-conscious logistics landscape.
