New Forms Driving Towards of Electrification This page introduces the example of the Nissan Serena. The diagram the Electric Era illustrates the current of recovered Hybrid cars are now second nature energy. Cars have been driving us around for a century now and we already have the 100% electric vehicle on our streets. Mobility is becoming electric, creating great improvements Helping us Running in fuel efficiency. Welcome to the new era. the navigation etc. start to move off Car navigation The stereo and navigation can Engine power is particularly required be run just by the electricity Do you remember those experiments at school? You know, and air resistance on the vehicle, kinetic energy is lost and when the vehicle starts to move and it stored in the battery. Even just also uses a lot of fuel here. Using the those science classes where you would connect a battery so speed decreases. By skilfully manipulating these inputs this greatly raises fuel efficiency. electric motor at this point helps the to a motor to make a small model car move forward. a driver can adjust the speed of the vehicle he or she is engine do its job and this also This kind of simple "car" works by using the motor to driving. improves fuel efficiency. Yellow arrows: convert electrical energy into motion: Channel electricity Surely there is a way to recover even just part of this Electric motor Electrical energy current through a motor and it turns. Well, the opposite is also kinetic energy lost when we slow down? Yes, there is with a possible. Turn the motor by external energy and it can motor. When the driver's foot is taken off the accelerator Main battery Preserving energy The electrical power recovered generate electricity. and the vehicle is gradually slowing down as it coasts, or by energy regeneration is then when the brake is applied, it is possible to convert the stored in the battery. Using a motor to convert kinetic energy into electricity by turning the motor with the energy into electricity energy from the wheels. In this way, we can make In an automobile you will find an engine. We're familiar with electricity from the motor without using fuel. We call this the word but what does it actually do in the car? Well, it energy regeneration, and the power can also be stored in Sub-battery burns fuel (gasoline) and then uses that heat to create the battery for later use. kinetic energy to drive the car. In recent years, though, car- Red arrows: Energy current makers have been developing vehicles using another kind A diverse "electric" world Engine of kinetic energy source: A motor powered by electricity, There are now all kinds of EVs and hybrid cars on the just like those models we all know from our school days. market. In a car you press down on the accelerator to power the Hybrid cars combine both an internal combustion engine engine and speed up. To do the opposite, you should then and electric motor, and by utilizing energy regeneration just reduce the kinetic energy and slow down. When you they try to moderate how much we use the engine. For brake or take your foot off the accelerator, there is friction example, when the vehicle is parked (or "idle"), the engine is

But not only at these times, when the The re-launched Nissan Serena is one example. Naturally, if

Yet fuel consumption has been greatly Diverse Electrification still expensive. And, since the car needs an engine plus a improved and without raising the price, meaning it remains Hybrid vehicles are now available at motor and large battery, it requires a special design layout a low-cost vehicle with no sacrifice to the space inside the various stages of electrification. As and the amount of space left inside the car will often suffer vehicle. the graph above shows, the higher as a result. This is the era that we have arrived at today, one where we the ratio of electrification, the better the fuel efficiency. However, recently the "electric choice" has been greatly can choose cars within a variety of "electric" stages Future expanding. Even with a motor and battery in the car, there according to our mobility wishes.
