Nearly a year ago, Terzo Power Systems officially launched its electrohydraulic pump systems designed for on- and off-highway mobile vehicles and industrial applications.
Terzo Power Systems developed the world’s first compact and energy efficient smart hydraulic solutions for the electrification of fluid power. Their flagship product, the Hydrapulse, is a complete electrohydraulic system that is a fully integrated power-on-demand hydraulic power unit with built-in intelligence. The energy efficient system, with an electronically controlled motor and pump assembly, are all contained in a small, compact footprint.
Terzo Power Systems is the brainchild of Michael Terzo, a mechanical engineer who graduated from Montana State University and launched the company in 2014 with one goal in mind — to bring a new level of simple, compact, and energy efficient technology to the market. The Hydrapulse is not a traditional hydraulic system but a fully integrated product.
Hydrapulse enables the electrification of fluid power systems such as steering, coolant pumps, air compressors, hydraulic power units and auxiliary systems in industrial, truck, mobile and much more. Terzo Power System engineers consult with OEMs and manufacturers every step of the way to support their system applications to help them become fluent and knowledgeable in electrification of fluid power. The Hydrapulse’s plug-and-play system is fully customizable and can be installed with minor design adjustments configured easily and independently from manufacturer settings.
Terzo has been working with mining manufacturers to simplify their machines. “Since our product is perfectly suited for electrification and hybridization, our customers in the mining sector are OEMs that are launching either a BEV or HEV vehicle platform to address emissions,” Terzo said. “This is primarily driven by the need for diesel emission reduction in underground mines where air circulation is critical and reduction of diesel emissions directly impacts the costs of operation on the air systems.
“The vehicles that are being developed with our system include rock drills, shovels, loaders, and trucks for underground,” he said. “Typically, these are specialized vehicles for the mining sector but we are also working with OEMs on their earth moving vehicles that can operate in mining and construction.”
Terzo said that the HydraPulse technology is the only fully integrated hydraulic system on the market that can be powered directly off the high voltage dc bus either from the battery system or the hybrid-electric system.
Any hydraulic work function on a mine vehicle that needs to be powered off a high voltage dc bus or electric engine-generator system is highly suited to the HydraPulse. “We can provide almost any power level of hydraulics needed for vehicles in the 300-hp range and below. We typically work with the vehicle OEM to integrate our system into their vehicles at the system level,” Terzo said. “This ensures we can provide a hydraulic system that is typically well over 70 or 80% more efficient than a traditional hydraulic system.”
When converting a vehicle over from traditional fluid power architecture to Terzo’s advanced power-on-demand type of system, Terzo said it can easily work with vehicles that are typically below 500 kw of power and below.
“We bring extreme energy savings to any hydraulic system which is a big deal for any electric or hybrid platform but many times the improvement in troubleshooting, maintenance, or controls can be the driving factor. For instance, we can remove over 90% of the components typically seen on a hydraulic system which will improve the size (75% smaller), weight (80% lighter), and complexity of a mining vehicle or machine and significantly help with troubleshooting, serviceability, and controllability,” Terzo concluded.
