John Deere's first electric excavator,
the 145 X-Tier, is powered by Kreisel
Electric's immersion-cooled battery modules.
Las Vegas. These new models offer industrial and marine customers
increased packaging flexibility in smaller vehicles while still using the
patented immersion-cooling technology.
The available 400V KBP63 module weighs about 400 kg (880 lbs.)
and measures 1111 x 795 x 351 mm (43.7 x 31.3 x 13.8 inches). The battery
system can be connected in series or parallel, with up to 16
packs and 800V applications, according to Kreisel.
Coming in 2024 is the 20-kWh KBE20.400 400V battery system,
which weighs 150 kg (330 lbs.) and has a 40-kW continuous discharge
and 80-kW peak discharge (10 seconds). Also expected in 2024 are two
40-kWh options: the KBE40.800C and KBE40.800S 806V (max) systems.
Both weigh 275 kg (605 lbs.) with 80-kW continuous and 150-kW
peak discharge; the difference is packaging - the .800C model measures
774 x 504 x 440 mm (30.5 x 19.8 x 17.3 inches) while the .800S is a
" long version " at 1,436 x 504 x 228 mm (56.5 x 19.8 x 8.98 inches).
" We see the clear and growing need for battery and charging solutions
for the off-highway industry, " said Jennifer Preston, global director
of John Deere Electric Power. " Together with Kreisel, we are
expanding our battery portfolio to include even more versatile, scalable
power to meet a wider range of application needs as we continue
to work toward a future with zero-emissions propulsion and
pursue our goal of demonstrating viable low- and near-zero-carbon
power solutions by 2026. "
Deere claims to have more than 3 million customer field hours operating
electric-drive (E-Drive) machines. The manufacturer plans to
deliver 20-plus electric and hybrid-electric models across Deere and
the Wirtgen Group by 2026. These machines will include electric
compact-utility tractors, commercial and residential mowers, Gator
utility vehicles, and more than 20 models of construction equipment.
Deere also is intent on developing a charging ecosystem that can
be scaled to meet operating conditions on a variety of jobsites.
Charging requirements will differ by market segment and applications,
the company said, from needing both stationary and mobile
options to versatile ranges and charge times. Deere says its machines
will feature common automotive-style connections to allow for
shared charging-station use where possible.
" John Deere recognizes the important role and opportunity charging
infrastructure presents when it comes to the successful progresTRUCK

New 20-kWh and 40-kWh Kreisel batteries, which were revealed at
CONEXPO, offer increased packaging flexibility for smaller vehicles.
