Jacobsen And E-Z-GO At Forefront Of Battery Power: Jacobsen and E-Z-GO have been at the forefront of battery powered equipment in the turf maintenance and golf sector for many years, from the E-Z-GO RXV golf cars to the Jacobsen Eclipse 322. Now, E-Z-GO has introduced a range of ELiTE vehicles, activated by Samsung SDI lithium technology, offering zero-maintenance batteries with a five-year unlimited amp-hour warranty and increased energy efficiency.
The E-Z-GO ELiTE vehicles are a case in point to
illustrate how battery power has evolved and the benefits it can bring. Launched
into the UK market at the beginning of 2017 it has represented a major step forward in golf car technology
delivering exceptional value to golf course operators.
New ELiTE Series vehicles are powered by
hundreds of Samsung SDI lithium cells that are loaded into a single battery
pack. The battery pack is controlled by an advanced Battery Management System
that monitors efficiency, temperature, state of charge and the health of the
batteries. These batteries are used to safely and reliably power electric cars,
e-scooters, power tools and many other electrically powered vehicles, equipment
and appliances.
The vehicles are powered by
zero-maintenance lithium batteries that don’t require watering, terminal post
checkups and cleaning like traditional lead acid batteries do. This is good
news for businesses and individuals operating golf cars, as there is less
downtime and maintenance to be carried out on the vehicles.
Charging time is
significantly reduced, and ELiTE vehicles allow courses to “opportunity
charge,” plugging vehicles in for quick charging sessions between rounds that
can rapidly restore significant levels of energy to the battery system, as
opposed to the lengthy recharge cycles required by lead-acid batteries.
The batteries in ELiTE
vehicles have also been developed to be lighter than traditional lead acid
batteries. ELiTE Series vehicles batteries are half the size and a fraction of
the weight of lead-acid batteries, with the aim of reducing turf damage and
soil compaction due to vehicle weight.
Jacobsen and E-Z-GO are brands
under the umbrella of Textron Specialized Vehicles, so when Jacobsen began
development of its latest diesel-electric hybrid and all-electric greens mower,
the Eclipse 322, it was a sensible move to consult the design engineers at E-Z-GO. Much of the technology in the
battery-powered Eclipse 322 is taken from the E-Z-GO RXV, another stalwart
machine in the evolution of battery powered equipment. The automatic braking
system and the main drive axle of the Jacobsen Eclipse 322 are shared with the
RXV in particular.
All the systems and
functions on the Eclipse are powered by electricity, the only difference is
whether the electricity is produced ‘on the go’ as with the diesel-electric
hybrid machine or stored in a battery pack as on the all-electric version.
Once you use electricity to power the machine, you
can then use reasonably sophisticated electronics to control the functions on
the machine. On the Eclipse the transport speed between greens can be set, as
can the cutting speed when on the green; this can be locked in by the course
manager using a PIN passcode, which cannot be overridden by the operator.
Again, using electronic control, the steering in
transport mode reacts much the same as a car, but when cutting mode is engaged,
the ratio changes and becomes more responsive allowing the operator precise
control.
However, the major benefit is the machine’s ability
to control the number of cuts per metre when mowing. This ability to precisely
control the frequency of cut (FOC) is unique to this mower and, like the
transport and mowing speed control, it can be locked in by the course manager
ensuring that every green is cut to exactly the same specification.
This is achieved because it is now possible, for the first time on a
ride-on mower to control the relationship between reel speed and the forward
movement of the mower. On a standard hydraulic-powered greens mower, the reels
rotate at approximately 2000 rpm. The faster you move across the green, the
cuts per metre reduce; conversely the slower you move, the number of cuts per
metre increase, because the reels are spinning at a constant rate.
Now, with the reel motors and traction motors
electrically driven, it is possible using electronic control, to slow the reels
as the machine’s speed decreases and then increase reel speed as the speed
across the green increases, therefore maintaining the number of cuts per metre.
Why is this important? It means that for the first
time the course manager can guarantee his members that each and every green
will be cut to exactly the same specification, ensuring consistency across all
18 putting surfaces.
The Eclipse also features individual reel lift and lower; the electric lift arms can be actuated individually, particularly useful when alternating the width of the clean up pass. As battery technology develops in the car industry, it will eventually cascade down into the turfcare sector and perhaps we’ll see some significant new developments in the way we maintain our outdoor environment.
