The Nissan LEAF is a fully electric car which is designed from the start to be electric. The car has a range of 100 miles and a top speed of 90 mph.
Engine and Batteries
The car has an AC synchronous electric motor of 80 kW (107 bhp) with a torque of 280 Nm. The motor is powered by 48 lithium-ion (Li-ion) batteries with a total capacity of 24 kWh. The batteries are located under the seats. This gives the car a low center of gravity. The battery pack will be covered by an 8-year, 100,000-mile warranty.
Top speed of the car is 90 mph and has a 100 miles/charge based upon US EPA LA4 City cycle. At 55 mph on the highway in 95 degrees and the A/C on, expect the range to be 70 miles.

Sound
“Approaching Vehicle Sound for Pedestrians
The system makes it easy for those outside to hear the vehicle approaching, but the sounds do not distract the driver and passengers inside. Thus, the needs of pedestrian safety, as well as driver and passenger comfort, are met. The sound system is the first of its type to be introduced by an automaker.
In addition to reducing air pollution, Nissan LEAF and other electric vehicles (EVs) reduce noise pollution, making them transformative in yet another way. Unlike their gasoline-powered cars, EVs and hybrids run quietly. Today’s noisy traffic corridors have the potential to possess an almost serene ambience if populated with cars and trucks that are quieter.
While silence is golden, it does present practical challenges. In response to public concern that quiet EVs and hybrids can surprise pedestrians and the visually impaired as they approach, Nissan has developed a set of distinctive sounds that will come standard with Nissan LEAF to ensure a positive experience for drivers, passengers and pedestrians alike.
In developing the sound system, Nissan studied behavioral research of the visually impaired and worked with cognitive and acoustic psychologists. After looking at applied original technology developed to reduce vehicle noise and conducting tests in Japan and abroad, the Approaching Vehicle Sound for Pedestrians system was created.
The sine-wave sound system sweeps from 2.5kHz at the high end to a low of 600Hz, an easily audible range across age groups. Nissan worked to avoid a sound range that would add unnecessary noise to the environment (around 1,000Hz).
Depending on the speed and status (accelerating or decelerating) of Nissan LEAF, the sound system will make sweeping, high-low sounds. For instance, when Nissan LEAF is started, the sound will be louder, so a visually impaired person would be aware that a nearby car was beginning operations. And when a car is in reverse, the system will generate an intermittent sound. The sound system ceases operation when Nissan LEAF tops 30km/h and enters a sound range where regular road noise is high. It engages again as Nissan LEAF slows to under 25km/h.
Use sounds to alert pedestrians
The system is controlled through a computer and synthesizer in the dash panel, and the sound is delivered through a speaker in the engine compartment. A switch inside the vehicle can turn off sounds temporarily. The system automatically resets to “On” at the next ignition cycle.
The Approaching Vehicle Sound for Pedestrians system conforms to guidelines set by Japan’s Ministry of Land, Infrastructure and Transport in its report, “Measures for dealing with the silence of hybrids and similar cars,” released in January, 2010.
Charging
The car as an 3.3 kW onboard charger for the battery and comes with a portable trickle charge cable (120V/20-A). As the name implies, this will be primarily used for opportunity charging and is not recommended to be the primary method of charging. For that, Nissan has a home charging dock which uses a 220/240V 40A dedicated line in the home. A full charge will take 8h on a 220/240V home charging station.

The Quick Charge (Left) and Home Charge (Right) Connector
A 480V quick-charging capability will eventually be available in many markets once a standard is set. 480V quickcharge 80% full will take 30 minutes.
Prototype Quick Charging Station
It is possible to set a charging timer in the car and control the car’s functions and charging from any computer or internet-enabled phone.
Further, the Nissan LEAF’s navigation system will be able to show the charging locations along the route.
Home Charging
Regenerative Braking
Instead of wasting braking energy into heat like a fossil fueled car, the Nissan LEAF uses regenerative braking. During braking, the motor is used as generator which will slow the car down and also charge the batteries of the car.

Energy Usage
A fully charged battery with a capacity of 24 kWh provides a range of 100 miles in the city. Therefore the consumption is 240 Wh / mile. The average US residential retail price for electricity in 2010 is $0.11 / kWh. The price per mile is 0,240 kWh x $0.11 = $0.026 or 2.6 dollar-cent per mile. A full battery load will cost 16 kWh x $0.11 = $2.64. With these full batteries there is a range of 100 miles.
