SUNCAR Electric Construction Machines

Electric excavators are the future

With the development of the world's first battery-powered electric excavator, SUNCAR is one of the pioneers in the electrification of construction machinery. In the years that followed, SUNCAR was involved in the development and construction of several hundred electric construction machines of all sizes - in collaboration with various companies.

These machines are now successfully in use around the world, proving their reliability, durability as well as user-friendliness. The political push for CO₂ reduction driven by climate change leads to ever stricter emission limits up to mandatory zero-emission construction sites, which are already a reality in some Scandinavian cities and where self-explanatory only electrically powered construction machines are allowed. In addition, electric machines are ideal for all indoor applications such as renovations, basements and tunnel construction due to the elimination of exhaust gases and are already widely used there.

In addition to emission-free working, noise pollution is also massively lower with electric drives than with comparable diesel-powered construction machines, which brings great advantages for those involved, especially on inner-city construction sites, as well as in enclosed spaces.

Ecological performance

Despite the resource-intensive production of the battery and in some cases high CO₂ emissions during power generation, the life cycle eco-balance is in most cases significantly better compared with the diesel-powered equivalent. Over its entire service life, for example, the TB1140E generates 75% less CO₂e emissions than a comparable diesel engine based on a Swiss consumer electricity mix (181.5 g CO₂e / kWh), with particulate emissions even being completely eliminated.

Proven and powerful

The e-construction machines developed by SUNCAR with modern high-performance lithium-ion batteries allow all-day operation at high performance and can thus completely replace conventional diesel machines in terms of performance.

Thanks to our careful dimensioning of the drive and the battery capacity required for it, the excavator can easily survive every working day with a short intermediate charge during the lunch break. The installed electric motor together with the proven original hydraulic system allows a higher torque and thus a higher performance and dynamics compared to the original diesel-powered machine. Due to the permanently installed battery, our e-construction machines also achieve a much greater flexibility compared to cable-driven construction machines, where care must always be taken with the sensitive cable and the operating radius is therefore severely limited.

Thanks to their robust construction and sophisticated thermal management, the machines can be used in all conditions without hesitation and have, for example, even proven themselves in the harsh and cold Norwegian weather all year round. In addition, the excavators are designed for a long service life of at least 12,000 operating hours. The electric driveline requires very little maintenance, does not need a particulate filter and is much more efficient, as it dynamically adapts to the required power and, unlike combustion engines, does not consume any energy during idling. As a result, operating costs can be greatly reduced and maintenance intervals increased.
