10 Electric Car for 2010 and 2011 - (8) Think










Highlights

The THINK City is an electric car that demands very little of you. In fact, not much more than a mobile phone. Just an overnight power top-up, and it’s ready to go in the morning.

THINK City is a modern urban car. With zero local emissions and an energy efficiency three times that of a traditional combustion engine car, it is a car for the environment. And it is a fun car for you. A choice ofsodium or lithium batteries allows you to accommodate your car to your driving style, travelling up to 160 kilometers in one charge, with a top speed of 110km/h. Driving a silent car will give you a totally new experience.




Environment

Concern for the environment has been at the heart of the development of THINK City. It is not only environmentally sound to drive, but the car itself is designed to be recycled.



  • Engineers, developers, buyers and designers have focused on the same thing: clean recyclable materials, non-polluting production processes, and the best possible use of materials.
  • The dashboard can be completely recycled.
  • The fabric, body, supports, air ducts, adhesives and fixings are designed using the same recyclable materials.
  • The plastic bodywork and other plastic panels are unpainted, reducing both energy consumption and toxins, while also making the panels easier to recycle.
  • The batteries are returned to the supplier at the end of their useable life.



Safety

The THINK City is a safe vehicle to drive both in cities and on highways, as proven by its conformance with the CE-marking criteria and EU homologation requirements (M1 certificate) – in fact, it is the first EV ever to be awarded a pan-European homologation certificate.

To become the first EV ever to achieve these exacting standards, the THINK City has been put through extensive testing and validation, including hundreds of computer simulations and correlations, over 50 sled tests and more than 20 real crash tests.
Comprehensive electrical testing and validation has also been conducted over extended periods, including 30cm deep water wading and total submergence in salt water with all electrical systems activated.

THINK City structural design safety attributes:

Main space-frame:
  • Energy absorbing front crash rail
  • High tensile steel throughout
  • Robotically welded
Interior:
  • State of the art seatbelt system
  • Seat belt pretensioners
  • Seat belt load limiters
  • Dual airbags
  • Energy absorbing foam surrounding occupants
  • IsoFix child restrains system
  • Passenger Airbag OFF switch
  • Intertia OFF switch that cuts off all power in event of an accident
Upper space-frame:
  • High performance aluminium profiles
  • Roof crush / rollover protection
Door frame:
  • Ultra high tensile side impact beam
The key to a safe car is a structure that ensures good crash performance. The backbone of the THINK City is a strong lower frame made of high tensile steel, this frame carries all the suspension and crash loads and is designed with a stiff passenger compartment and deformable zones in the front and rear.
An extended aluminium space frame is mounted to the lower frame, with thermoplastic body panels and all other components attached to it in turn for maximum cockpit robustness.
Internally, the City boasts dual airbags and a state-of-the-art seatbelt system, and carefully selected high density expanded polypropylene materials are used for the dashboard, knee bolster, door panel trims as well as inlays for head protection in the headlining and the pillar trims to provide maximum passenger safety in the event of a collision.
The door panel energy absorbing foam includes a pusher block function, where occupants are pushed out of a possible crash zone. Lower pillar trim is specially designed to protect lower ribs in event of a side impact.
All of our testing and development has been conducted in close conjunction with a number of specialist safety partners, including Autoliv, Bosch Germany, British Steel Automotive Engineering Group UK, Lotus Engineering UK, Ford Motor Company UK, TNO / TASS Netherlands and Tecosim UK.



Exterior and Interior

The combination of a smart choice of materials, clever details, and clean lines and surfaces have made the THINK City a prize-winning Norwegian design.



The powerful shoulder line and well-defined wheel arches give the car a stance that clearly highlights its superior road handling and excellent driving features. The side indicator lights prominently placed on the wheel arches add innovative looks to exemplary functionality. THINK City's body is made of recyclable ABS plastic, designed for city driving, ideal for anyone who would like to avoid visible scratches and irritating little dents.
Interior
The car’s interior is designed to give the driver a pleasant environment, where the emphasis is on providing a clear view of the traffic. The interior is spacious, with instruments that are easy to read. Form, quite simply, follows function. The glass rear hatch allows you to see right down to the bumper of the car behind you when reversing. Parallel parking could not be easier.

Charging

Charging your THINK City is just as easy as charging your mobile phone. Plug it in a conventional socket, charge over night, and wake up to a fully charged car the next morning.


Where can I charge?


You can plug in to a conventional 10A or 16A socket, 230V. Plugging into a 16A socket will enable faster charging.


How far can I drive on one charge?


You can drive up to 160km on a fully charged car.


How long does it take to charge the THINK City?


THINK City with Lithium battery; 0-100% 8 hours

THINK City with Zebra battery; 0-80% 7 hours, 80-100% 4 hours




Batteries

THINK City has been designed to cope with a variety of battery systems and technologies.


Battery systems

The traction battery module is located underneath the seats. Here, the module is well protected and ideally placed from a safety point of view. This gives a good distribution of weights between the front and rear axel, and provides the vehicle with a very low centre of gravity.
The battery compartment can accommodate different types of battery systems. Currently, THINK Cityfeatures the Zebra sodium battery and Lithium-Ion battery from EnerDel.

Sodium batteries: Zebra

The Zebra (Mes-Dea) battery has high energy density, and provides long range performance, independent of ambient temperature. It is a “hot” battery, which means that the operating temperature is between 260 and 360 degrees. The battery is also made from environmentally friendly materials. This option is perfect for users who have a regular and frequent usage pattern. Active materials in the Zebra battery are sodium and nickel. The hot materials are contained in a vacuum insulated and sealed container. Thus, these batteries operate very efficiently in areas with very hot and very cold climate.

Lithium-based systems: Enerdel

The lithium battery operate at ambient temperatures. This means that the car does not have to be plugged in when not in use. THINK is co-operating with Enerdel.
