ELECTRIC CARS: THE BEST ALTERNATIVE
An electric car is a modern vehicle which is propelled by electric motors, getting energy source from rechargeable batteries. The first electrical cars were said have been produced in the 19th century and they are more quitter, no exhaust emissions and lower overall emissions unlike the internal combustion engine cars.
Gustave Trouve in November, 1881 presented an electric car at an international exposition in Paris. In 1884, Thomas Parker also built an electric car in Wolverhampton using his own personally designed high capacity rechargeable batteries. In 1888, the first real electric car, The Flocken Electrowagen was designed and launched by German inventor, Andreas Flocken.
Electric cars were among the preferred methods for automobile propulsion in the late 19th and early 20th century, providing a level of comfort and ease of operation that could not be achieved by the gasoline cars of the time . The electric vehicle stock peaked at approximately 30,000 vehicles at the turn of the 20th century.
All Electric cars or vehicles (EVs), also referred to as battery electric vehicles, have an electric motor in place of an internal combustion engine found in common vehicles. The vehicle uses a large traction battery pack to power the electric motor and must be plugged in to a wall outlet or charging port, otherwise called electric vehicle supply equipment. It doesn’t contain any typical fluid components like fuel pump, fuel line fuel tanks and the rest.
Charging an Electric Car
Charging an electric car can be done at a variety of stations designed for charging; these charging stations can be installed in both houses and public areas along the traffic. It may look complex but it’s simple.
If you have a driveway and can park your car beside your house, then you can just plug it straight into your domestic mains electricity supply. However, it is slow and could take many hours to fully charge an empty battery, depending of course on the capacity of the battery. It could takes a minimum of 8 to 14 hours or even more .
A fast charger like a home fast charging point, should typically take between four and 12 hours to fully charge a battery, depending on how large the battery capacity is.
COMPONENTS OF AN ELECTRIC CAR
Battery (all-electric auxiliary): In an electric drive vehicle, the auxiliary battery provides electricity to power vehicle accessories.
Charge port: The charge port allows the vehicle to connect to an external power supply in order to charge the traction battery pack.
DC/DC converter: This device converts higher-voltage DC power from the traction battery pack to the lower-voltage DC power needed to run vehicle accessories and recharge the auxiliary battery.
Electric traction motor: Using power from the traction battery pack, this motor drives the vehicle’s wheels. Some vehicles use motor generators that perform both the drive and regeneration functions.
Onboard charger: Takes the incoming AC electricity supplied via the charge port and converts it to DC power for charging the traction battery. It also communicates with the charging equipment and monitors battery characteristics such as voltage, current, temperature, and state of charge while charging the pack.
Power electronics controller: This unit manages the flow of electrical energy delivered by the traction battery, controlling the speed of the electric traction motor and the torque it produces.
Thermal system (cooling): This system maintains a proper operating temperature range of the engine, electric motor, power electronics, and other components.
Traction battery pack: Stores electricity for use by the electric traction motor.
Transmission (electric): The transmission transfers mechanical power from the electric traction motor to drive the wheels.
NEW ELECTRIC VEHICLES MODELS
The automobile industry will witness some beautiful and fantastic electric cars by year 2021, some of the new models are;
• AUDI Q4 E-Tron:
Audi will expand the E-Tron nameplate later this year with the Q4 E-Tron. A close relative of the Volkswagen ID.4, Audi’s compact electric SUV will be built on the Volkswagen MEB modular electric vehicle platform. Based on its size, the Q4 E-Tron will compete with the likes of the Tesla Model Y and Volvo XC40 Recharge. Audi has not yet announced the Q4 E-Tron’s driving range, which is the distance a vehicle can go between charges or fueling. The current range estimate for the Q4 E-Tron is 280 miles, but it is based on EU test standards, which are more optimistic than the U.S. ones. That is considerably less than the Model Y.

• BMW i4
BMW calls its stylish new i4 electric vehicle a “four-door coupe.” This EV is projected to have a range of 300-plus miles and a fast charging system that will add about 60 miles in just 6 minutes. The i4 also promises sports-car performance, with 530 hp and 0-to-60-mph acceleration in under 4 seconds. (It’s probably no coincidence that those acceleration numbers are similar to Tesla’s Model 3, a rival.) The fact that BMW is bringing out an electric vehicle with a broader appeal than the quirky-looking compact i3 will give consumers in the market for sporty luxury more choices.

• Chevrolet Bolt EUV
Chevrolet says it will begin production in summer 2021 of a new Chevrolet Bolt, along with a taller SUV sibling called the Bolt EUV. Both models will be built on General Motors’ BEV2 platform and are part of the company’s big electrification initiative. Chevrolet says the Bolt EUV will include Super Cruise, the hands-free driver assistance technology previously available only on certain Cadillac models. No official word yet on range, but the outgoing Bolt is rated for 259 miles.

• FORD F-150 EV
The F-Series pickup truck has been the best-selling vehicle in the U.S. for decades, and with all the EVs coming to market, it makes sense that Ford would add an electric option to its biggest moneymaker. Anyone who has been following the horsepower/torque arms race among various truck manufacturers over the past few years will know that electric motors promise to be as capable as gasoline and diesel engines for use in vehicles intended to tow and haul heavy loads. One other small advantage the electric F-150 will have over its traditional counterparts is a “frunk”—a storage compartment where the gasoline or diesel engine would have lived. Ford says both the truck and its batteries will be built at the company’s River Rouge manufacturing complex in Dearborn, Mich. There will also be an F-150 hybrid.
On sale: Mid-2022
• MERCEDES BENZ EQC
The EQC is an electric version of the Mercedes-Benz GLC SUV. It’s more practical than the Jaguar I-Pace because it has more room, and it is less expensive than the Audi E-Tron. Right now, Mercedes says the EQC will have a range of more than 250 miles, based on the rating standard used in Europe, but range-conscious customers should wait for the Environmental Protection Agency’s estimate, which will probably be lower. The carmaker says the EQC’s infotainment system can map out the most efficient routes and find charging stations. Mercedes also has plans to unveil electric versions of the GLA and GLB SUV models, which will be named the EQA and the EQB, respectively, as well as an electric version of the flagship S-Class sedan called the EQS. The EQS will have an estimated 435-mile range, according to European test standards.
