Geely’s new city e-car is intriguing

30After Tesla, the Wuling Mini EV car is the best-selling electric car in the world in 2022.
A result that acts as a beacon for the market, which pays increasing attention to the proposal of small e-cars especially suiting urban environments.
In this scenario, was born the Geometry Panda Mini by the Chinese Geely multinational manufacturer.
The tender bear, symbol of the Chinese culture, is then the inspiration of this car, recently exhibited in a mall in Hangzhou. What are the main characteristics? The car is 3.07-metre long, 1.52 m width, 1.60 m high and has a wheelbase of just 2.02 m. The powertrain is composed by a single electric front motor featuring 41 HP, which allows an autonomy of about 150 km.
The price is very interesting: the price list indicates from 5,000 to 7,000 Euros.

Audi, electric under test at Morocco rally

Absolute first in the race for the evolution of the innovative electric protype with range extender. Audi RS Q e-tron E2 is in fact engaged in Morocco Rally, with all official Audi Sport crews, for which very challenging conditions are expected: high temperatures, dunes, rocky stretches and fast tracks on compact ground.
The car is equipped with three electric powertrains: two MGU (Motor Generator Unit), one close to each axle, perform traction, whereas a third unit acts as generator to share in the recharge of the high-voltage battery.

Arnau Niubó Bosch, project leader track operations explained «The programme provided for nine days of test, so that each crew could test the car for three days. The main targets were two: developing the car in view of Dakar and making drivers and navigators become acquainted with the novelties introduced by the E2 evolutionary step. The car lightening, in fact, opens new opportunities for the trim and suspension setting. We are going towards the correct direction, to the extent that the electric traction discharges power to the ground more smoothly than in the past».

The car seems to differ notably from the past: the overall lightening allows opting for a less hard calibration of shock absorbers, to full benefit of comfort.

The highly miniaturized components are the glue that holds todays’ technological world together. The most powerful semiconductors are the core of all electronic systems and the various application fields include also the electric vehicles’, so that the company aids manufacturers in operating with more efficiency. The core of pre-integrated system solutions by Bosch is the advanced drive module, ADM, which integrates the single systems of propulsion, steering and brakes in a single harmonized flexible module. Simplified interfaces and a coherent software architecture decrease the complexity and assure the optimized communication among components. This modular approach that combines hardware, software and services allows manufacturing companies to integrate the ADM according to their requirements. The rolling chassis prototype, created through the collaboration with Benteler, specialized in the production of chassis and bodyworks, proves the highest possible level of pre-integration and represents a development platform for electric battery vehicles. With its integrated safety and control technology, the new flexible smart charging cable works also without the in-cable control box with 230-V socket. Without the so-called “charging brick” Bosch cable weighs less than 3 kg. On average, it corresponds to a 40% weight reduction compared to conventional cables with control box.

A new cooling concept: here is the durable electric motor by Mahle

Concerning this, the latest development comes from the automotive supplier Mahle: the traction motor can run indefinitely with high performance. A new cooling concept makes this technological leap possible. The new electric motor is surpassingly clean, light, and efficient and can be assembled without the use of rare earths by customer request. The new development is suitable for passenger cars and commercial vehicles as well as construction machines and tractors. With the SCT E-motor, Mahle thus becomes a full-range provider in the field of electric drives and covers all needs from e-scooters to heavy-duty commercial vehicles as well as off-road and industrial applications. The new item will be presented for the first time at IAA Transportation in September 2022 in Hanover.
Martin Berger, Vice President Corporate Research and Advanced Engineering at Mahle said: «Building large electric motors that deliver short-term high performance is easy. What was still lacking on the market until now were durable yet compact drives to make electric vehicles unrestricted for everyday use. Our new SCT E-motor is the solution. On the drivetrain side, this clears the way for the replacement of the combustion engine in all vehicle classes. In 2021, MAHLE presented a groundbreaking wear-free and scalable traction motor for passenger cars that runs very efficiently over a wide rpm range».
The SCT E-motor, on the other hand, is designed in such a way that it is particularly efficient within a certain rpm range. Despite its very compact and light design, its continuous output is more than 90 percent of its peak output. Unique on the market, this groundbreaking high ratio means a technological leap and allows the use of electric vehicles of all kinds even under demanding conditions. A classic example is driving an electric truck over mountain passes or the multiple sprints of a battery electric passenger car. These scenarios are only insufficiently covered by the electric motors available on the market up to now.
In designing the product, MAHLE opted for what is known as a permanently excited motor, since this type enables a very compact design and no energy has to be transferred to the rotor as “excitation current”. This makes the motor efficient and wear-free. Neodymium magnets, currently the strongest permanent magnets that can be produced, are used to generate the magnetic field in the motor. However, to achieve greater independence from raw material prices and geopolitical developments, the SCT E- motor can also be designed without magnets for greater independence. Thanks to the unique contactless transformer developed by Mahle, the magnet-free variant would also be wear-free and run efficiently, while only requiring slightly more assembly space.
