48kWh Long Range Leaf Built by Nissan Engineers for Fun, Research and Development

In a demonstration of their passion for innovation, Nissan engineers have created a prototype Nissan LEAF with a 48 kWh battery – in their spare time.

Following the manufacturer’s principles of on-going research and development of electric vehicles, the 48 kWh prototype carries a battery twice the size of the original Nissan LEAF production model, with a 75 percent increase in driving range, in everyday conditions.

It was created by a group of engineers at Nissan’s Technical Centre in Barcelona (NTCE-S), whose passion and commitment to their work has given rise to the Nissan Innovation team. The team of volunteers take on a range of exciting endeavours, pushing the boundaries of what is possible with electric vehicle technology.

The prototype, codenamed “Cocoon” in reference to the American sci-fi film of the same name, was built to compete in the Spanish motorsport event, ECOseries – a new initiative which rewards “efficiency and fuel economy rather than outright speed.

Dario Fernandez, Senior Engineer at NTCE-S, said:

“It has been a great privilege to work on this project and to see our finished prototype race in the ECOseries. We all have a real passion for what we do and being able to work on prototype projects gives us the creative freedom to be as innovative and forward-thinking as we possibly can.

Battery range improvement is important to the on-going adoption of electric vehicles, so this was a great opportunity to utilise our knowledge of zero-emissions technology to look at how battery range could potentially be extended in this particular application.”

Gareth Dunsmore, Director of Electric Vehicles at Nissan Europe, said:

“As a pioneer of the electric vehicle market, Nissan has consistently innovated and advanced its technology to remain at the forefront of the zero emission sector. Whilst there are no plans to put this prototype into production, it serves as a useful exercise in thinking outside the box, something our engineers and designers do on a daily basis. The Nissan LEAF 48 kWh showcases the passion our employees have for their work.”

These extra-curricular projects feed in to Nissan’s Intelligent Mobility vision and allow employees to draw on their expertise, skills and experience to experiment with technology, design and engineering. The Intelligent Mobility framework informs all of Nissan’s future products and technologies, with the aim of developing a smart, connected, sustainable zero emission transport network.

Nissan introduced the Nissan LEAF as the world’s first mass-market, 100 percent electric vehicle in 2010. Since then, the auto-manufacturer has continued to design and produce innovative zero emission solutions, including the e-NV200 pure electric light commercial vehicle and a longer range LEAF with a 30 kWh battery.

Although the two 24kWh batteries take up all the space where the rear passenger leg-room used to be, it’s not beyond the realms of possibility that with better packaging a 48kWh production model might be built. Popular rumour has it that the next Nissan Leaf will feature a 60kWh battery or, in other words, two 30kWh packs together. Ironically, the Nissan e-NV200 – an award winning electric van – is built at Nissan’s Barcelona facility and might be better suited for the twin battery pack due to its additional size and flat floor.
