Renault revealed the Kangoo Z.E. Concept at the 2008 Paris Motor Show. The Zero-Emissions all-electric powered concept has given birth to this Kangoo be bop Z.E. demonstrator that was unveiled to Renault shareholders in Paris. The Z.E. Concept featured technologies that Renault and its partner Nissan will install in their upcoming electric vehicles. Through their alliance the two companies aim to be the leaders in mass-produced electric cars from 2011 when Renault starts.

RENAULT INTRODUCES THE KANGOO BE BOP Z.E. ELECTRIC VEHICLE DEMONSTRATOR
* Renault profited from the Annual General Meeting of its shareholders today in Paris, France, to take the wraps off its new prototype electric vehicle, Kangoo be bop Z.E.. The technology featured on this vehicle is very similar to that featured on the brand's upcoming production electric vehicles which are currently under development.
* In July, Kangoo be bop Z.E. will embark on a Europe-wide tour during which it will be available for test drives.
* The mass marketing of affordable Renault electric vehicles will begin in 2011.
* The Renault-Nissan Alliance is targeting to become the leading producer of massmarket zero emission vehicles.
Specific, functional styling
Kangoo be bop Z.E. is derived from the production Kangoo be bop and is instantly recognizable by its Energy Blue body colour, while the Renault logos on the grille and wheels are picked out in satin-finish blue-hued chrome. Inside, the satin-finish chrome and metallic acidic green trim ensure a unique ambience which is further expressed by the specific grey velour upholstery and
embroidered 'printed circuit' motifs.
Like the Z.E. Concept concept car which was unveiled at the 2008 Paris Motor Show, Kangoo be bop Z.E. is equipped with low-energy LED (light-emitting diodes) front and rear lighting with a view to optimizing energy use. Meanwhile, the car's aerodynamics have been significantly reworked in order to reduce energy consumption. Kangoo be bop Z.E. sits on 18-inch full disc wheels, and its ground clearance has been lowered by 20mm compared with that of the production Kangoo be bop.
Linear displays on the outside of Kangoo be bop Z.E.'s doors show how much charge is left in the battery by simply activating the remote central locking control. Inside, another gauge to the left of the instrument panel provides the driver with a permanent indication of how much battery charge remains.
An all-electric motor
Kangoo be bop Z.E. is an all-electric zero emission (in road use) vehicle. It is powered by a 44kW (60hp) electric motor which revs to 12,000rpm and which boasts greater efficiency (90 per cent) than an internal combustion engine.
Kangoo be bop Z.E.'s electric motor is coupled to a reducer which replaces the gearbox traditionally mated to heat engines. This reducer has a single, constant output ratio. Electrical energy is transmitted to the motor by a power electronics unit which incorporates the controller that delivers the required amount of energy to the rotor.
Latest-generation lithium-ion batteries
Kangoo be bop Z.E. is equipped with compact, innovative lithium-ion batteries produced by AESC (Automotive Electric Supply Corporation), a Nissan-NEC joint venture which was founded in April 2007. The performance of these batteries compared with former-generation nickel metal hydride batteries is superior in every domain, including performance, reliability, safety and efficiency.
Lithium-ion batteries do not suffer from the so-called memory effect which results from incomplete charge cycles, ultimately leading to a fall in capacity. The AESC battery is expected to deliver between 80 and 100 per cent of its original capacity for a duration of six years.
The compact dimensions of lithium-ion batteries enable the vehicle's configuration to be optimized and a wide range of applications to be envisaged. In the case of Kangoo be bop Z.E., the battery is located underneath the dashboard. It consequently doesn't encroach on either cabin space or boot capacity, making it possible to keep the same arrangement of four individual seats as that seen on the heat-engined Kangoo be bop.
The battery comprises 48 modules, each of which incorporates four elementary cells. It is inside these cells that the electrochemical reactions take place, enabling electrical current to be produced or energy to be stored.
A year and a half ahead of the launch of Renault's production electric vehicles, the 15kWh battery of the Kangoo be bop Z.E. prototype delivers a range of approximately 100km. When released, Renault electric vehicles will profit from an evolution to their battery technology which will take their real-world range to 160km.
Last but not least, lithium-ion batteries are recyclable and the Renault-Nissan Alliance is actively working on establishing recycling processes and infrastructures adapted to automotive batteries.
Express charging
Kangoo be bop Z.E. is charged via a MarechalTM-type socket located behind a flap at the front of the vehicle alongside the right-hand headlamp. The other end of the cable is fitted with a normal plug which connects to the mains supply.
This plug permits two different battery-charging modes:
* a conventional charge via a household mains supply (10A or 16A 220V) which can charge the vehicle in a timescale of between six to eight hours. This mode is perfectly suited to vehicles which are parked up overnight or during the day at the workplace.
* a so-called quick charge using a 32A 400V three phase socket, enabling up to 80 per cent of Kangoo be bop Z.E.'s capacity to be charged in approximately 30 minutes.
Twenty or so car manufacturers - including Renault - and energy groups have been working with the German group RWE with a view to developing a universal standard plug.
This universal standard plug was shown at April's Hanover Messe technology fair and will be used to charge the batteries of future Renault electric vehicles. This three phase plug can be used with a 400V supply and will enable a complete charge in approximately 20 minutes. This multi-partner agreement marks a significant step forward in the development of mass market electric vehicles.
Kangoo be bop Z.E. is also equipped with a brake energy recovery system which enables it to be charged while on the move.
The Alliance's electric vehicle strategy
The Renault-Nissan Alliance has its sights set on becoming the leading manufacturer of mass market zero emission vehicles. The Alliance is actively forging innovative associations with governments, city authorities and energy companies with a view to promoting the widespread use of electric vehicles across the world. Twenty-four such partnerships have already been sealed to date.
Renault and Nissan were among the first manufacturers to commit to achieving significant reductions in carbon dioxide emissions in recent years. Renault's strategy which was unveiled in January 2008 specifies the release of mass market electric vehicles by 2011.
The Renault-Nissan Alliance is planning to have a comprehensive range of high-quality, reliable, innovative and affordable electric vehicles. The first all-electric Nissan vehicle is due to be launched in the United States and Japan in 2010, and Nissan is set to market its electric vehicles worldwide from 2012.
Renault will start marketing all-electric models in 2011, beginning with a family saloon in Israel, and a utility version of New Kangoo in Europe. Two new, highly innovative vehicles are then scheduled for release in 2012.
Renault's zero emission (on the road), silent-running electric vehicles will incontestably break new ground, while at the same being affordable for the majority of road users.
