New steps towards electric boating

A motor that represents a development element for electric boating? Wave 300 was presented, an outboard motor with a power of around 300 HP, powered at 680 V, particularly advanced from the technological point of view and developed by Explomar, brand of Qingbo Exploration Energy Technology Co, company that is developing a project for the creation of hydrogen fuel cells.
Despite its 300 HP, WAVE 300 weighs 180 kg and has a modulable powertrain, with the quantity of variable HEDB – High Energy Density Lithium Batteries, which can be selected by users according to their autonomy requirements.
The cooling system is entrusted to a closed circuit that avoids the contact of whatever internal component of the motor with the sea water, protecting it against corrosive phenomena. The Chinese manufacturer’s promise is a very competitive price on the European market, too.

Four-wheel drive for Nissan X-Trail electric SUV

X-Trail is the last Suv presented by Nissan, in the four-wheel drive version it is pioneer in being equipped with the exclusive e-4ORCE and e-Power systems.
The new Nissan e-4ORCE technology is the evolution of the four-wheel drive on electric and electrified vehicles. The name allows guessing what are the novelties hidden behind this change of pace: a fully electric traction, 4 for the wheels that are moved by the two electric motors.
Nissan engineers have focused on three aspects: the joint operation of motors, frame control technologies and, last but not least, the study of case movements (roll, yaw and pitch) to minimize them in comparison with a conventional thermal vehicle.
The 4ORCE system is composed by two electric motors, one for each axis. The motor on the front axle can develop 150 kW (204 HP), the one on the rear axle 100 kW (136 HP), for 157 kW (213 HP) overall. They are managed by a sophisticated control unit able to adjust driving force and braking action on each single wheel.
Moreover, the motor allows the Suv to shift from 0 to 100 km/h in 7 seconds and, compared to a mechanical 4×4 system, the drive regulation on the 4 wheels is 10,000-time higher, as well as reaction times.
The torque is constantly distributed on the two axles and having mounted two equivalent electric motors in terms of weight allows a mass distribution that approaches 50:50, synonym of more frame stability and better handiness.

The e-bike by Fllow enters the market

The available electric vehicles on the market are increasing and motorbikes are included in this constant race, too. They have in fact opened the bookings for FUELL Fllow, electric motorbike presented in 2019, the first electric motorbike implemented by the motorbike brand created by Erik Buell committed to electric mobility. He, former Harley-Davidson engineer, is already the brain of the e-bike Flluid. The membership forecast in this photo is 3,000 units. Let us go into detail: the electric Fllow motorbike, which weighs 180 kg, is equipped with a proprietary electric motor, housed in the rear wheel hub, and it is available in 11 kW or 35 kW power. Its maximum speed is 140 km/h, it accelerates from 0 to 100 hour in 3.5 seconds. The 10-kWh battery has been designed as structural element of the frame and the recharge is possible with times of respectively 8 hours, 90 minutes and 30 minutes.

Electric Porsche Macan? The 2024-promise

There is a range of models to be shifted towards electric and Porsche Macan will be the next project to be born. The term is fixed in 2024, new debut date after new emerged delays connected with the software component have postponed the outset initially scheduled in 2023.
There are already some anticipations about powertrain performances: electric motors framed in an 800-volt project architecture and optimized to grant better power density. Actually, with the same absorption motors deliver higher torque.
Porsche will introduce silicon carbide semiconductors for the electric Macan and the magnet arrangement itself will be different. They research higher efficiency that will arrive at the wheel also from the separation of the front electric motor on the traction line, when unnecessary.
The two motors have maximum 611 horsepower and 1000 Nm of torque and energy will come from a 100-kWh battery, rechargeable up to 270 kW in direct current.

If Abarth becomes electric, too …

When real icons announce the switch to electric, there is no room for abouts about the collective motion in course. They have recently presented the Abarth Nuova 500e Scorpionissima, limited edition that joins unmistakable style and electric power. 1949 units are available, with exclusive graphics and a numbered authenticity certificate. Its performances can make it arrive in 7 seconds from 0 to 100 km/h due to the 155 HP supplied by the electric motor, powered by a 42-kWh battery. The manufacturer has explained that, by recharging it, just five minutes wiIl be sufficient to achieve an autonomy of 40 km in half an hour, to recharge it up to 80%.
It seems that soon other electric Abarths will join the range to make one of the major sports brands of Stellantis galaxy more appealing.
Moreover, it seems that more powerful 500e are coming and therefore Fiat and Abarth are working at new powertrains to achieve an Abarth exceeding 155 HP and 235 Nm.
What about the roar of the motor that has always characterized Abarths? The unmistakable “voice” of 1.4 turbo-petrol is artificially reproduced by a suitable sound generator.

Achievements, ZF produces 2 million electric motors

Die nächsten zwei Millionen E-Maschinen im Visier: Viele Elektrofahrzeuge werden von E-Motoren von ZF angetrieben. Hier gezeigt ist die Stator-Produktion im Werk Schweinfurt, dem ZF-Leitstandort für E-Maschinen. // Targeting the next two million electric motors: Many electric vehicles are powered with electric motors made by ZF. This is the stator production at Schweinfurt, ZF’s lead plant for electric motors.

Manufacturing anniversaries should never be underestimated. Already in 2008, the company was pioneer in Europe to bring out an electric motor for a premium mild hybrid. Meanwhile, ZF has not only expanded its product portfolio with technological innovations but has also strongly supported the trend towards electrifying passenger car drives – to cut down climate-damaging CO2 emissions. Especially in recent years, this went hand in hand with massive production capacity increases. ZF has adapted to the increasing number of call-offs and the high demand for electric mobility.
Stephan von Schuckmann, member of the ZF Board of Management and responsible for Electrified Powertrain Technology said “Our production anniversary is backed by long-term entrepreneurial decisions and innovative engineering spirit”.
ZF electric motors cover a broad range of applications from mild hybrids and plug-in hybrids to purely electric drive systems for passenger cars and commercial vehicles. The performance range is 50 kW to 550 kW, with torques of 75 Nm to 1,500 Nm.
ZF supplies its customers with electric motors as components but also has the expertise to integrate electric motors into vehicle drives and supply whole systems, respectively.
ZF offers complete axle and central drives including self-developed and -produced power electronics and reduction gear units for purely electric drives in passenger cars and commercial vehicles.
In view of globally increasing volumes and the high demand for electric powertrain technology, the next production milestone will be reached soon. “Our order books are well filled, the next two million units of electric motors will probably be produced in less than two years,” says Hintringer.
