Doosan Bobcat has introduced its new, all-electric Bobcat T7X compact track loader at the CES 2022 show in Las Vegas. The T7X is said to be the first machine of its kind to be fully electric and, according to company officials, offers the benefits of eliminating hydraulic systems, emissions and vibrations while providing cleaner, quieter machines.
“Doosan Bobcat is at the forefront of innovation, and we are proud to debut the all-electric technology of the T7X to help customers maximize both sustainability and productivity,” said Scott Park, president and CEO of Doosan Bobcat Inc. “Our focus remains on providing solutions and products that empower people to accomplish more and build a better world.”
“This machine is a technological feat for Bobcat and for the entire industry,” said Joel Honeyman, vice president of global innovation at Doosan Bobcat. ”We challenged the status quo to deliver a connected, all-electric machine designed for power and performance that previously was not possible. We are excited to share this advancement with the world and proud of the hard work that has gone into making this a reality.”
A 62 kW lithium-ion battery from Green Machine Equipment powers electric actuation and propulsion. The T7X is said to provide high-performance torque and more power than similar diesel-fueled track loaders. The traditional hydraulic work group has been completely replaced with an electrical drive system consisting of electric ball-screw actuators and electric drive motors. The new unit uses only one quart of eco-friendly coolant compared to 57 gallons of fluid in its diesel/hydraulic equivalent model. The all-electric platform enables instantaneous power and peak torque available at every operating speed, according to the company.
Doosan Bobcat collaborated with Moog Inc., a worldwide developer of motion control components and systems, to speed development of electronic control capabilities for the T7X. According to Moog officials, most centralized systems on a construction vehicle today have one motor and pump distributing hydraulic fluid; the pump is always running. With a traditional loader, the machine would waste energy on every axis for lifting, tilting, moving — even when the machine is stationary.
Moog designed a more efficient system using distributed control to send power only when and where the T7X needs it, such as lifting dirt or moving side to side, and thus wastes little to no energy. Moog’s system also efficiently manages motion and thermodynamics for the T7X, which keeps each component operating at the right temperature range, reduces energy use, and extends run time. And the system’s software learns to optimize movements and operations as the T7X works. Smoothing out the peak moments of energy use can boost run time by more than 25%.
Thanks to the sophisticated power management system, each charge can support common work modes for up to four hours of continuous operation and a full day of operation during intermittent use.
The T7X is ideally suited for operation in noise sensitive areas and indoors. It can also significantly lower daily operating costs, when considering the reduction in annual maintenance costs and elimination of diesel, engine oil, diesel exhaust fluid and hydraulic parts.
While the new T7X is eco-designed, it is also a smart machine featuring software connectivity via two-way telematics communications. The platform provides integral data about equipment performance, along with operator-focused data to change machine preferences, tune the performance to certain job situations and upgrade product features. This includes variable drive speed at full torque and other features not possible with a diesel-hydraulic machine.
To accompany the T7X, Bobcat will also introduce the world’s first all-electric attachments designed for specific tasks. The first to be developed include an electrically powered auger to dig holes, an angle broom to sweep clean and a material-handling grapple.
At CES, Doosan Bobcat also announced a strategic partnership with South Carolina-based Sunbelt Rentals, a leading rental equipment company in North America with more than 1,025 locations. Through this partnership, Sunbelt Rentals committed to a significant investment in a large fleet of Bobcat T7X all-electric compact track loaders and electric compact excavators, which will be co-branded and made available in 2022. Sunbelt Rentals will be the first national equipment rental company to adopt Bobcat’s battery-electric technology and make it available to customers, supporting the environmental, social and governance (ESG) focus for both companies.
