At the joint congress of Assodimi and Unacea, there was talk of electrification of construction machinery
Electric cars: myth to kill or futuristic innovation?
Nor for Walter Vinciotti, CEO of PRIVÉ, who spoke at the joint congress of Assodimi and Unacea with a speech with this title.
On July 1, this important event “Planet Machines 2022 – Technologies and services for sustainability” took place in Milan, which dedicated the morning to the theme of electrification and brought on stage:
Walter Vinciotti, CEO of PRIVÉ:
“Electric cars: myth to kill or futuristic innovation?”
Davide De Silvio, Head of Powertrain at FPT Industrial, Iveco Group:
“Powertrain electrification for road applications”
Antonio Stanisci, Commercial & Marketing Director at ALD Automotive:
“Transition to electrification”
“Neither myth to kill nor futuristic innovation – is the thought of Vinciotti – We are not facing a futuristic innovation because we are in full development of technology. And this is not even a myth to dispel because electrification is onechance very important for both large and small builders, for tenants “.
Opportunity is also for Davide De Silvio, Head of Powertrain for FPT Industrial, Iveco Group, who spoke the same morning, again on the subject of electrification. De Silvio has in fact emphasized how electrification is an option, also because it allows for a fresh start from the real needs of work, rethinking the machine and the machine architecture based on new criteriadisconnected from the needs and design of the old engines.
Let’s go back to the Vinciotti intervention and see the ideas he proposed.
A standard battery suitable for all machines cannot be found
First of all, let’s start by saying that: the electrification process of machines in the construction world does not involve the development of the perfect electric motor and battery. Far from.
In fact, not a standard battery can be found to fit all machines. Machines engaged in transportation, for example, will need batteries that supply power in a linear and continuous manner. An excavator or a lifter, on the other hand, must have a battery that can also handle work peaks, precise moments where more power is required, others when it is not needed.
Not just performance, but above all efficiency
Another important aspect to consider is that in the design of an electrical machine or in the electrification of an existing system, we must not only consider performance.
Performance in the electric motor is not all we need to aim for efficiency. Yes it is useless and harmful to develop more labor than is needed. We know how expensive it is to produce and store energy, this goes to build up the battery which is the most important part of the electric motor, the element that needs to be preserved the most.
Excessive labor production also has another negative effect. Energy production generates heat, heat is the enemy of the electric motor which with heat works less efficiently.
The drivers of the electrification market
- Environmental policies aimed at limiting emissions
- Internal environmental policies for charterers, manufacturers and contractors to reduce pollutant gas emissions. Many say they want to achieve zero power by 2050
- Possibility to use electrical machines for work inside buildings, tunnels, underground
- Reduction of noise and vibration
- Preparation of electrical machines for conversion to independent, remote-controlled, remote-controlled work
Barriers to overcome the prevalence of electrification
- Cost of ownership (ownership, administration, charging infrastructure)
- Autonomy not always secure (depends on many variables)
- Lack of a proper regulatory push that includes all the pollutants to be curtailed
Reliability and security performance
For the construction sector, which intends to move towards electrification, Vinciotti proposes to set the following goals:
We have just seen that performance in terms of developed power is not everything, on the contrary, we need to look at efficiency. In this case, however, performance means the ability to develop efficient and optimal solutions that can only be achieved by building know-how.
It is important to keep in mind several parameters: the required energy consumption on an hourly basis and the number of working hours, the type of machine and the type of work.
Machine downtime affects everyone: builders, suppliers and users.
But electrification allows you to prepare for and prevent problems, there are many tests that can be performed on the machine, set up controls, all to monitor its performance and check the aging of the battery and the machine.
Security is a key point.
Electricity introduces new risks, often associated with the situation. An electric machine used in a certain way or in a certain environment is not dangerous. If conditions change, it can stay.
The safety of a machine is determined both at the time of design / construction and at the time of use. So you need a serious design, but also instructions and training.
Electrification, like any new technology, also introduces new dangers that are not insurmountable but that need to be prepared. Even the logistics will have to arm themselves because it is not easy to ship batteries, manage new spare parts with new suppliers.
What should be aimed at for the electrification of the off-road sector?
There are 3 areas to focus on to develop off-road electrification:
- Development of dedicated components: collaboration between machine and battery manufacturers to arrive at increasingly efficient products
- Acquisition of industrialization processes
- Supply chain and training for conscious users
The trend towards electrification
Electrification is one established trend. Although in our country it is going slower than in others, there is no going back.
Antonio Stanisci, Commercial & Marketing Director at ALD Automotivewhen he again spoke at the Assodimi Congress on the subject of electrification, he explained that in In Europe, 25% of the cars registered in 2022 will be electric. “In Italy, the figure is 7/8% – have explained Get tired – but already if we look at them in the rent it is double. The rental anticipates the trends because the customer does not risk technological obsolescence with the purchase made by the tenant ”.
