Pon Equipment Reveals Electric Caterpillar Excavator

JAN 29 2019 BY MARK KANE 5

Full size electric excavators are coming faster than we might think

Pon Equipment from Norway, with support from Caterpillar, has developed an interesting conversion of a 28-ton Cat 323 Hydraulic Excavator to an all-electric Cat 323F Z-line.

This huge excavator received a massive 300 kWh battery, which weighs 3.4 tons and should last for 5-7 hours of work. For comparison, the C7.1 ACERT industrial diesel engine weight is around 1 ton.

Energy consumption must be 40 to 60 kWh per hour. The charging takes at least one hour for another hour of work using a common 43 kW three-phase industrial outlet in Europe.

The big advantage of the electric excavator is lack of emission and noise and hopefully also huge savings on fuel.

So far, eight of those were ordered by Veidekke in Norway, and one costs about $650,000.

Cat 323F Z-line specs:

  • 300 kWh battery
  • working time: 5-7 hours
  • 122 kW electric motor
  • charging at up to 43 kW (on-board three-phase charger, 63 A)

Just like to add they removed some of the weight (originally 11 metric tons) in the back, to compensate for the heavy battery (so the weight and balance is as close as possible to the original model). The price is only for the first one (which required a lot of time, and engineering efforts. They also ordered the best of everything, so some parts may be overkill, and may be changed at a later stage. Fuel savings are huge, and also the reduction in CO2 emissions. Due to the price of the excavator, and the limited running time will require a 25-30% higher price for the job they do, according to a contractor. In some areas diesel excavators will not be allowed anyway. It is fitted with marine grade lithium batteries to better withstand all the bumping and shaking. The heavy duty batteries cost 600 euros pr kWh. Way more then regular EV batteries. There are room for even more battery capacity is customers need that. They’re making 12 units in the first “batch”. It uses an EDITRON drivetrain from Danfoss (Danfoss mobile Electrification). Pon Equipment had to da a lot of work to make the electric system behave almost… Read more »

Thanks for all the detailed info! Very interesting.

It can also be conected to the grid while working.

I never understand why they always have to play stupid music over the sound of the action or they constantly talk over the video. This is annoying. I, personally, want to know what the machine sounds like.

So Tesla 100kWh battery is 590kg. In 3.4T space you could install 570kWh of Tesla batteries. Sounds like their battery packs are pretty inefficient as regards weight.
There is no doubt as they redesign this equipment for EV it will get more efficient. Currently they are just converting the ICE product, not making them from the ground up.
