Following a significant investment in hybrid engines and electrification research, Perkins has announced a range of technologies that will add real value to original equipment manufacturers (OEMs) as they design the next generation of off-highway machines.
Perkins has designed a range of hybrid and electric power solutions that are relevant and adapted to the construction machines of today.
The hybrid-electric, hybrid-mechanical and hybrid-hydraulic power technologies complement Perkins existing 0.5 – 18 litre range of diesel engines, ensuring OEMs and their customers benefit from machines that are more productive, quieter and have lower fuel consumption, whatever power solution they select.
Matt Coleman, product director at Perkins said: “Through our close technical collaboration with our OEMs, and using a huge amount of real field data, we develop solutions which are truly relevant to the construction sector. By collaborating with Perkins, OEMs can accelerate their research and development project, saving themselves time and money.”
To provide the close technical collaboration required to meet customers’ needs, Perkins has established a dedicated team – the Perkins Expanded Offering Product Team.
“Our research programmes into future power trains have focused on both fundamental technologies such as battery ruggedisation, and on system integration. We find ourselves in an excellent technology leadership position to help our OEM partners develop the machines of tomorrow.”
With access to millions of hours of machine operating data, Perkins has identified that the operating cycles of real construction machines varies from one application to another, and as machine size increases.
The duty cycles, operating conditions and packaging constraints for off-highway machines drive the need for specific configurations that are highly customised to the individual application.
“There isn’t one solution that fits all machines,” said Matt. “Perkins is establishing itself as an integrator with multiple hybrid and electric power technologies.
“The difference between off-highway machines in operating conditions means that there is limited, if any, value in technology transfers from other sectors such as automotive, truck or marine”
Perkins will offer hybrid and electric technologies across its EU Stage V power range from 6 to 470 kW (8 to 630 hp) The first technologies to be shown are:
There are several ways to incorporate the electric motor or generator, with Perkins preferred arrangement delivering excellent fuel saving benefits while moderating the installation impact and minimising the cost impact on the machine. The flexibility of the system provides opportunities for further efficiency and functionality improvements in the whole machine through use of 48-volt electrics.
This stores energy in a high-speed flywheel which can be delivered back to the machine. This is particularly useful in hybridising machines that run a cyclic operation and need very intense bursts of additional power. Apart from the very quick energy release, the advantage over hybrid-electric is in installation size.
This stores energy in hydraulic accumulators. In some machines this can be the most practical and cost-effective hybrid solution as it easily integrates into existing machine hydraulic systems. Software and integration of machine systems are key to achieving great savings from this technology.
Tom Carlill, new product introduction programme manager in the Perkins Expanded Offering Product Team, said: “Our conversations with OEMs indicate that their research and development departments are under intense pressure to implement regulatory changes and customer features to current machines, as well as to plot a path towards future technologies.
“By working with the Perkins Expanded Offering Product Team they will be able to achieve better project outcomes and deliver more productive, cost competitive and more relevant solutions for their markets. By sharing our advanced tool set, skilled team and excellent facilities OEMs will achieve these superior results quickly and at the lowest cost.”
