Electrical Cars FactsPowered purely by advanced lithium-ion batteries, our all-electric range of vehicles are designed to tackle the challenge of CO2 emissions - by producing none at all.
So you enjoy a clean, quiet, smooth drive that doesn’t damage the environment. And because we are developing more renewable ways to power, build and recycle every EV we make, the sustainability of our commitment will grow and grow.
Technology has advanced to the point where EVs are now more practical, more powerful, and faster to drive and recharge than ever before. Making them easier to own and more fun to drive. And they look pretty good, too.
Here are some key EV components (and their terminology explained):
• Connecter box - where the plug is connected to main current
• Power inverter - changes DC into AC (battery = DC, motor =AC)
• Transformer - DC-DC converter which changes 400V (from engine) into 12V
(for the auxiliary, e.g. AC, lights etc)
• Battery charger - the device that converts AC 220V to DC 400V to charge the battery
• Electric motor
• Reducer – this is the speed reduction gear (like a gearbox). The gear ratio is fixed, front
and reverse
What Nissan is discovering ???We have always worked to make our vehicles more energy efficient. But now we’re taking this strategy to another level.
The Renault-Nissan alliance is leading the global automotive industry in developing zero-emission vehicles for everyone, thus helping address the widespread concerns of global warming. Our advanced, compact lithium-ion batteries are class-leading. And our new partnerships with governments and leading organisations all over the world are helping to make our EVs easier to obtain, own and enjoy.
In the summer of 2009, the first of these cars will be revealed.
And beyond that? More cars, more choice, more to enjoy - all built, powered and recycled by an increased level of renewable energy. And of course, all with zero emissions.
What exactly will be ready ???What will our first EV look like? The design is still under wraps, but what it will give you isn’t.
Its unique design will be built around a pure-electric platform. It will have room for five passengers and their luggage, and give a range of more than 95 miles. Maintenance will be simple, it will be equipped with the latest lithium-ion battery - and there’ll be no compromise on performance.
The EV Nissan will introduce to Japan and North America in 2010 will have new, unique body style on an all-new vehicle platform. It will be big enough and powerful enough to carry five adults. It will have the performance of a typical 1.6-litre petrol-engined car and can be recharged to 80% battery capacity in around 25 minutes.
The lithium-ion batteries developed for the EVs are more efficient, more powerful and faster to recharge than anything gone before. They have twice the density of conventional batteries, doubling the vehicle’s cruising ability. Their thinner structure allows for more room inside the vehicle itself. Advanced power output gives better acceleration and recharging capabilities are improved thanks to more efficient regenerative braking.
Lithium-ion batteries Key points:
• Lithium-ion batteries are the key component in an EV
• They have twice the capacity, are half the size and provide 50% higher power output
compared to a conventional battery of the same weight
• Their compact design allows for improved vehicle packaging as the pack will be installed
under the EV’s floor, so cabin and/or cargo space isn’t compromised
• Their laminated structure offers improved cooling capacity for better reliability
• Lithium-ion do not experience the ‘memory effect’ which occurs when incomplete charging
cycles lead to a drastic decline in range
• Each Nissan battery should maintain 80% of its capacity - even after five years of use
• A battery pack is composed of battery modules and a battery module is composed of
four cells
