BMW i Carbon Usage For Car Lightweighting

There is a car engineering strategy, known as “lightweighting”, aimed at developing lightweight structure cars to improve fuel efficiency, dynamics and driving. The lighter the car, the faster it accelerates, the more maneuverable and efficient it is. Using lightweight materials in car building leads to less strain on the engines, reduced fuel consumption and better car handling.
BMW knows that and strives for lightweighting to achieve better performance for its electric cars. To reduce car weight, the German carmaker uses innovative material at car building – the carbon fiber.

The carbon fiber (Carbon fiber reinforced polymer/CFRP, carbon fiber reinforced plastic or carbon fiber reinforced thermoplastic/CFRTP) is a light and highly resilient composite containing the carbon fibres and the matrix of plastic. It is 50% lighter than the steel and 30% lighter than the aluminum, but it is extremely strong and safe for being used in the industries requiring high strength-to-weight ratio and rigidity – aerospace, civil engineering, and, of course, car engineering industry.

BMW EfficientDynamics: All You Need For Megacity Driving

Our interest in BMW i models and respect towards company technologies is endless. EfficientDynamics is one of the BMW concepts we absolutely like at Bmwiclub.
BMW EfficientDynamics is incorporated in every BMW i car. Last time we told about innovative BMW eDrive concept, which is one of the core technologies in EfficientDynamics strategy. Now let’s understand the concept behind BMW EfficientDynamics and its major technologies.

Understanding EfficientDynamics Concept
EfficientDynamics is a strategy developed at BMW to reduce car fuel consumption and toxic emissions while increasing dynamics. It is a mix of electromobility systems, efficiency measures and high-tech functions coupled towards improving car energy management, construction, aerodynamics, combustion engines and electric motors. Increased driving performance and reduced power consumption – this is EfficientDynamics from BMW.
Especially clearly the efficient driving concept from BMW is manifested in its electric cars, the i3 and i8, intended for driving in mega cities where car dynamism, lightweight construction, low CO2 emission and sustainable mobility are most needed. Urban driving and vibrant city lifestyle requires from the car optimal combination of efficiency and dynamics, just what the BMW concept is all about.

Combustion engines
BMW EfficientDynamics covers the family of latest generation petrol and diesel engines: BMW 3- and 4-cylinder petrol engines and the award-winning BMW TwinPower Turbo inline 6-cylinder petrol engine, each one delivering outstanding dynamics, being low on emissions and fuel consumption.
In the i8 model, a 3-cylinder, 1.5-liter TwinPower turbo gasoline engine is paired with eDrive technology to combine all the benefits of an electric motor and a gasoline engine, delivering dynamic yet economical driving performance.

Electric drivetrain
BMW electric drivetrain is build up on the concept of “more energy, less fuel”. This concept is embodied in BMW eDrive technology gathering together the electric motor, the high-performance lithium-ion battery and intelligent energy management strategy. BMW cars driven on electric mode with a fully charged battery show breathtaking speeds and have the range enough to cover most daily destinations. BMW EfficientDynamics mixed with eDrive create smooth electric driving, which is free from noise and local emissions. The electric motor and battery are all manufactured in-house.

Lightweight construction
The lower the car weight, the faster it accelerates, the more maneuverable and efficient it is. The essential components of BMW EfficientDynamics are improved aerodynamics and lightweight materials, used to reduce the fuel consumption level and car emissions. Lightweight construction is vital for an electric car. It allows for dynamic performance, maneuverability and minimum power consumption. To additionally reduce car weight, the BMW uses innovative material at car building – the carbon. It is 50% lighter than the steel and 30% lighter than the aluminum, but it is as strong and safe. BMW i models are the first cars, featuring this high-tech material in the construction.

Aerodynamics
Improved aerodynamics is one more component of BMW EfficientDynamics concept. Many car design elements are optimized in terms of aerodynamics to ensure car efficiency and optimized drag coefficient. An aerodynamic car from BMW combines such measures as the automatic air vents, the active rear spoiler, the Air Curtain in the front apron, the Air Breather that channels the air on the front wheels, and more components for airstream control, which in turn lowers fuel consumption and CO2 emissions. The aerodynamics of the BMW EfficientDynamics concept cars is also enhanced with the aerodynamic, optimized wheel rims.

Energy-saving functions
BMW EfficientDynamics technologies include energy-saving functions such as the Brake Energy Regeneration, Automatic Start/Stop, Brake Energy Regeneration, Electric Power Steering, Gear Shift Indicator. Minimum fuel consumption and low emissions are the core tasks behind each and every energy-saving technology in the BMW car.
Our opinion is that the regeneration of brake energy is one of most effective technologies used by BMW for energy management. The idea is that the braking energy converts into electrical power to charge the battery. Thus, less effort is required from the engine to charge the battery, which in turn leads to decreased fuel consumption and low emissions.

Efficiency & Dynamics – All We Need For Megacity Driving
It is obvious for us that each technology of BMW EfficientDynamics is well-thought-out and helps the driver to adapt the car to driving situation while at the same time saving energy and driving more efficiently. Although BMW EfficientDynamics is currently the part of every BMW car, the BMW i3 and i8 are the perfect example of company’s EfficientDynamics concept. Electric cars from BMW i are an exclusive combination of two seemingly conflicting properties, the efficiency and the dynamics.

What Is BMW eDrive. BMW i Cars With eDrive.

BMW eDrive is the electric drive concept made up from the electric motor, the lithium-ion battery and intelligent energy management. These three magic things work in tandem to create electric driving which is free from noise and emissions. BMW models with eDrive technology are endowed with magnificent dynamics, acceleration, mobility and sustainability.

BMW Electric Motor
Electric motor is one of the high-tech developments BMW Group has ever done. BMW cars driven on electric mode with a fully charged battery show breathtaking performance on the road and have the range enough to travel most daily distances. With no local emissions and silent operation, BMW electric motor is capable to reach short bursts of speed required to overtaking a car in front.

BMW Lithium-Ion Battery
BMW eDrive technology intends to use a battery to power the propulsion of the electric car. The lithium-ion battery is an electricity storage device of high-performance, required for electric driving. To power its i-concept cars with premium quality batteries, BMW teams up with Samsung SDI. To minimize range/charge loss and enhance battery service life, the carmaker incorporated a cooling system in order to keep battery at optimum temperature rate. As to the charging, it is possible even at a conventional household socket. To charge the battery to its full capacity is also possible at public charge stations. For charging your BMW i model, BMW offers The ChargeNow mobility service. Use it when on the move to find the charging locations in your area, wherever and whenever you are right now. However, if you want maximum convenience, 100% safety and fast charging, there is an option to install a BMW charging box developed for home use. It can be mounted on the wall of the house and garage. It saves about 4 hours of charging time and protects from technical risks that may be caused by charging the car battery at a conventional socket.

BMW Intelligent Energy Management
Intelligent energy management is one of the core technologies within BMW EfficientDynamics concept. Intelligent energy management is about balancing the relations between the electric drivetrain and the battery, and the electric motor with ICE. The task is delivering perfect performance with less power consumption. Depending on the route and driving situation, navigation data calculates the optimum time to start electric mode driving or battery charging; this energy management technology saves up to 10% of energy enabling the car to go longer distance on a pure electrical mode. The kinetic energy released during braking or deceleration is stored in the high-performance battery and is available when necessary to boost overall performance. To help the driver to increase electric range, there is the Eco Pro mode which additionally reduces power consumption, and the tips for efficient driving are shown on the control display.

eDrive technology in the BMW i8 and i3
Founded in 2011, BMW i started to work on the two initial concepts: the i3 all-electric mega city vehicle and the plug-in hybrid sports car i8. The BMW i3, a locally emission-free car for city driving, became the first i brand model, launched in 2013. Year later, it was followed by the i8, as the most progressive sports car, packed with the internal combustion engine and the electric motor. Both innovative models have been developed with the principle of intelligent energy consumption and sustainable electric mobility. Both equipped with BMW eDrive technology units – the electric motor, the high-performance battery, and internal systems for the efficient management of energy flows within the car.

BMW eDrive in the i8
The gorgeous plug-in hybrid i8 is the first sports car boasting the consumption and emission figures of a compact automobile. The mixture of eDrive system and petrol engine guarantee an efficient and dynamic driving performance. Comfort, Eco Pro, Sport and eDrive modes are available to adapt the car for current driving situation and road conditions. For purely electric driving, there is a magic eDrive button. Pure electric driving is possible at speeds of up to 120 km/h with eDrive.

The Comfort mode with eDrive allows driving the i8 without support from the internal combustion engine until the battery is almost depleted. The ICE is activated at 60 km/h if the eDrive mode is not pressed.
The energy released during braking or deceleration is stored in the high-performance battery and converts into electric energy to recharge the battery and boost car electric range.

BMW eDrive in the i3
BMW i3 is the first car produced under BMW “Project i” and developed for pure electric driving. Powered by an all-electric drivetrain, this appealing car from BMW is designed to deliver emission and odour free performance at fully electric drive. This is a compact auto for urban driving and BMW’s first car featuring carbon-fiber-reinforced polymer to improve the energy consumption. BMW is offering a range extender option powered by gasoline engine with a small fuel tank.

The engine engages when the battery level drops to a pre-specified point, and takes a role of a generator producing electricity to extend driving range. In this BMW i model, intelligent power management, the electric motor and high-performance battery from Samsung operate side-by-side to gear all car systems towards exceptional electric driving.
