Efficient system solutions for the electrification of mobile machines

For economical operation, electrically driven machines must be reliable, responsive, and persistent, without tedious recharging. The operating company also demands low noise emissions and low maintenance costs with high energy efficiency. Electric and hybrid drives place new demands on the working hydraulics. The demand for innovative hydraulic solutions will increase in the upcoming decades.

New legislation on exhaust emissions, especially in major cities, will soon require a change in thinking and concrete actions.

Smart electrohydraulics as a success factor – more efficiency with perfect working hydraulics
The electrification of mobile machinery’s primary focus is often on the traction drive.  There is a risk that the application-specific large energy-saving potential of working hydraulics is often overlooked.

Classic hydraulic drive and control solutions for mobile machines are often not designed for efficiency but primarily to reduce initial costs, offering energy-saving potential of up to 60%.

The following advantages are offered to the machine manufacturer with coordinated system components:

  • New application possibilities thanks to reduced noise emissions
  • Cost-saving potential for batteries due to the reduced energy demand of the working hydraulics
  • Greater range and longer operating times with the same battery size
  • High energy efficiency and long service life as the basis for successful electrification
  • Positive impacts on operating costs
  • All these points have a positive effect on life cycle costs.
  • Optimized hydraulics as a key success factor for electrified machines

Machinery manufacturers often start with the drive train when electrifying their vehicles. The electric motor, power electronics, and a battery system replace the combustion engine, transmission, and tank. The potential for optimizing the working hydraulics is often ignored and the existing hydraulic architecture is taken over from the combustion engine vehicle – with all its disadvantages.

Adapting the working hydraulics to the new requirements opens up new possibilities for the electric vehicle: The higher energy efficiency enables the installation of a smaller battery or a longer range for the vehicle.

Quiet machines enable new application possibilities
Without a diesel engine, the working hydraulics often come to the foreground acoustically. Speed-controlled drives and quiet hydraulic pumps are capable of significantly reducing the noise emissions of electrified working machines. This enables new application possibilities, particularly in noise-sensitive residential areas and at night.

New opportunities to automate processes
Perfectly tuned electrohydraulic controls can be precisely activated and easily integrated into the machine concept. Whether and to what extent it makes sense to invest in modern hydraulics depends on the specific application and the market positioning of the machine manufacturer.

Rental market can record the operating time of hydraulic attachments with new Webtec run-time meter

Webtec has a developed a new run-time meter which is ideal for construction and agricultural machinery where specialist hydraulic attachments can be centrally owned and rented on a ‘time-used’ basis. The RFS200 also ensures that owners can conduct maintenance on a time-used basis, rather than machine hours, thus allowing for more astute and cost-effective management of hydraulic system health.
