The Swift Incursion of Electric Cars

The Swift Incursion of Electric Cars

Introduced over 100 years, electric cars are seeing an ascent in prevalence today for a significant number of similar

reasons they were first well known.

It’s difficult to pinpoint the innovation of the electric cars to one innovator or nation. Rather it was a progression of leaps forward– from the battery to the electric engine– in the 1800s that prompted the main electric vehicle out and about.

For instance, Ferdinand Porsche, founder of the sports car company by the same name, Porsche, developed an electric car called the P1 in 1898. Around a similar time, he made the world’s first half breed electric car– a vehicle that was fueled by power and a gas engine.

Thomas Edison, one of the world’s most productive inventors, thought electric vehicles were the better innovation and worked more to assemble a superior electric vehicle battery.

While all the starts and stops of the electric vehicle industry in the second half of the 20th century helped show the world the promise of the technology, innovators at the time envisaged electric vehicle’s high demand thereby exploring ways to improve the technology.

Tesla’s announcement and subsequent success spurred many big automakers to accelerate work on their own electric vehicles. In late 2010, the Chevy Volt and the Nissan LEAF were released in the U.S. market. The first commercially available plug-in hybrid, the Volt has a gasoline engine that supplements its electric drive once the battery is depleted, allowing consumers to drive on electric for most trips and gasoline to extend the vehicle’s range. This made other automakers in the US roll out electric vehicles.

With this developing enthusiasm for electric vehicles, let’s discover some intrusions of electric cars in the auto industry.

Audi Aicon


The very shape of the Audi Aicon reveals that it is a car from another world, an automobile of the future. The technology used in the concept vehicle has also been systematically designed for this world. It presumes a transportation infrastructure in which autonomously driving automobiles are a given on every street. Road users are connected to one another and their surroundings.

This also means that traffic will be less hectic and flow more smoothly in the future than is imaginable today. Even at moderate speed limits, long distances can be covered at a high constant speed of around 130 km/h (80.8 mph). Passengers experience the journey as comfortable cruising without constant braking and accelerating.


Accidents will also be a thing of the past thanks to the highly advanced sensor systems and networking. Passengers in an automobile like the Audi Aicon will therefore no longer need classic restraint systems. The drive and the total vehicle have also been optimally adapted to this new world of mobility.

A highly efficient electric drive provides for the dynamics of the Audi Aicon.

A total of four electric motors are located in the area of the front and rear axles. The energy storage units are integrated into the area below the floor. These are solid body batteries with considerably more energy capacity than lithium-ion batteries.

The four electric motors produce a total of 260 kW and 550 Newton-meters (405.7 lb-ft). Each drives one wheel, enabling electronically controlled, variable Quattro all-wheel drive. Maximum acceleration played a less important role in the specification than maximum efficiency and thus also range.

This operating strategy is also pursued by the powertrain and electric brake units, which use recuperation to recover energy. The targeted lightweight construction of the multimaterial body and optimized aerodynamics also help the Audi Aicon to achieve ranges between 700 and 800 kilometers (435.0 – 497.1 mi) on a single charge.


Even charging has been reduced to a minimum. Thanks to a high-voltage system with 800 volts, the Aicon’s battery unit can be charged to 80 percent of capacity in less than 30 minutes. The car is also equipped with a unit of inductive, i.e. wireless, charging.

The Aicon manages both without a driver. In an AI Zone, it can pull up to a charging station on its own and charge its battery without any human assistance.

Mercedes Benz EQA Concept


The eye-catching spiral-shaped light signet underlines the electric concept, its design evoking the copper windings of an electric motor and the animation visualizing electrical impulses.

The EQA Concept features two electric motors, with a system output that can be increased to over 200 kW thanks to scalable battery components, and permanent all-wheel drive delivers impressive dynamic performance. The two drive programs “Sport” and “Sport Plus” offer a different front to rear torque distribution, allowing a choice of individual drive characteristics.


In combination with the intelligent Mercedes-Benz operating strategy, the Concept EQA achieves a range of around 400 kilometres, depending on the battery capacity installed.

The highly efficient lithium-ion battery with pouch cells is the innovative battery system that has a model-specific total capacity of over 60 kWh.


The Concept EQA can be charged via induction or wallbox and is also ready for rapid charging. The vision for using public charging stations is “seamless charging”: this Mercedes me-based service makes it easy to charge and pay at different charging stations.

Porsche Mission E Concept


It is not just a passionate sportiness that makes up a Porsche but also a high level of everyday practicality. Accordingly, the Mission E can travel over 500 km on one battery charge, and it can be charged with enough energy for around 400 km more driving range in about fifteen minutes.

The reason: Porsche is a front-runner in introducing innovative 800-volt technology for the first time.

Doubling the voltage– compared to today’s electric vehicles that operate at 400 volts– offers multiple advantages: shorter charging times and lower weight, because lighter, smaller gage copper cables are sufficient for energy transport.


A moveable body segment on the front left wing in front of the driver’s door gives access to the charging port for the innovative “Porsche Turbo Charging” system. Via the 800-volt port, the battery can be charged to approximately 80 percent of its capacity in around 15 minutes– a record time for electric vehicles.


As an alternative, the technology platform can be connected to a conventional 400-volt charging station, or it can be replenished at home in the garage via convenient inductive charging by simply parking over a coil embedded in the floor of the garage from which the energy is transferred without cables to a coil on the car’s underbody.

Volkswagen ID Concept


The I.D. is the first compact Volkswagen based on the newly developed Modular Electric Drive Kit – or MEB. The future MEB models will be cars that are only available with purely electric drive.

This approach to the design results in a range of advantages, in particular with regard to the package – the layout of the powertrain components, the ancillary equipment, and the interior features. The I.D.’s zero-emission drive system consists primarily of the electric motor and the power electronics and transmission integrated into the rear axle, a space-saving high-voltage flat battery on the floor of the car and ancillary equipment integrated in the front of the car.

The electric engine has a power output of 125 kW (170 PS). The almost silent performance is truly amazing. The I.D. can accelerate from 0 to 100 km/h in under 8 seconds from a standing start and has a top speed of 160 km/h.


Subsequent production versions could also be offered with more or less powerful electric motors. In parallel, the concept also envisages that it will be possible to configure the I.D. with different battery capacities. As is the norm for petrol and diesel-engine cars, this would allow the drive system to be modified to suit the owner’s individual needs. The I.D. will have a range of between 400 and 600 kilometers.

The version of the high-voltage battery used in the I.D. is located in the chassis. As a crucial link, the power electronics control the flow of high-voltage power between the motor and the battery. The power electronics module converts the direct current (DC) stored in the battery into alternating current (AC) and a DC/DC converter supplies the onboard electronics with 12 V power.

Power is transferred from the motor to the rear axle via a single-gear transmission. The motor, power electronics, and transmission form one compact unit. The position of the battery on the floor of the vehicle has a positive effect on the neutral handling characteristics, as it gives the I.D. a very low center of gravity, like that of a racing car. The I.D. is also characterized by an optimal weight distribution of 48:52 percent.


The battery can be charged by cable or using an inductive charging interface in the front of the car. To charge by cable, a separate charging plug is needed to connect the car to an electrical outlet, but for inductive charging, all the driver needs to do is park the I.D. over a so-called charging plate, with a little help from the electronics to make sure it is in exactly the right position.

Over and above that it will be possible to send the car to an inductive charging station, too. Thanks to the rapid charging system the battery is already 80% charged after just 30 minutes.

Kenya is one of the fastest growing economies in sub-Saharan Africa with a growth rate of 5.9% in 2019.  The African Development Bank Group (AfDB) said the growth rate of 5.9% recorded in 2019 is driven mainly by services on the supply side and household consumption and firm investment on the demand side.
