Think Ox

Think werd in 1991 opgericht als maker van kleine, elektrische miniauto's. In 1999 zag de City het licht dankzij de 100 miljoen dollar die Ford als nieuwe eigenaar in het bedrijf liet stromen. In 2003 nam het Amerikaanse bedrijf weer afscheid van Think, sadder but wiser. Ondanks de eerdere mega-investeringen leed Think schipbreuk waarna een groep Noorse investeerders het failliete bedrijf overnam.

In 2007 werd de nieuwe generatie City aangekondigd, na het verzamelen van nog eens tientallen miljoen dollars aan investeringen. Het model borduurt voort op de eerste compacte elektroauto van eind jaren negentig. De bedenker van de Segway heeft aandelen en werkt mee en Tesla Motors zorgt voor de accusystemen.

Nu timmert het Noorse Think aan de weg met de nieuwe City en de Ox. Deze laatste is een veelbelovende vijfpersoonsauto die elektrisch rijdt. De Ox is nog een concept car, dus mogen de makers prestaties claimen zonder ze te bewijzen.

TH!NK Ox – A platform vehicle

TH!NK Ox is a modular platform concept, designed for electric drive vehicles, for both the European, North American and Asian markets. It is the basis for a variety of vehicle styles, starting with the TH!NK Ox Crossover 5-seater. This is possible due to a space frame concept featuring the main crash structure and the batteries centrally placed in two compartments in the lower frame. The TH!NK Ox picture gallery shows an MPV version and a coupé version. The MPV version is suggested as a taxi with a larger luggage space. The MPV version is designed for easy entry and exit, and a spacious and easy access luggage trunk. The coupé and sports versions have a larger battery capacity for higher performance.

The TH!NK Ox Platform design allows two different standards of battery packs;

  • High stack: two compartments, allows use of low cost, high range sodium batteries
  • Low stack: gives space for flat Li Ion packs, allows lower/upper frame for sports car and flat flow applications

Scandinavian and clean design Think’s sustainable Scandinavian design has formed the basis for this truly innovative clean car.

TH!NK Ox is distinguished by the TH!NK product family design characteristics. It mimics the clean choice of materials from the TH!NK city, with a prizewinning, unpainted and recyclable exterior and a 95% recyclable interior material concept, made possible through the ABS and PP interior systems. A solar panel in the roof keeps the vehicle’s interior cool when the engine is switched off, or can even supply enough power to run the sound system on the beach.

Think electric drive The base model of the TH!NK Ox will have a 60kW electrical powertrain, capable of accelerating to 100km/hr in less than 8.5 seconds and reaching a top speed of 130km/hr. The vehicle will be powered by a choice of either sodium batteries or state-of-the art lithium technology battery packs, allowing optimal adaption to the type of use and geographic region. The lithium-ion batteries will employ a next generation nano-phosphate electrochemistry with an unprecedented combination of power capability, energy density, and safety.

The TH!NK Ox driving range is targeted at 200km for combined highway and city summer driving (US06 driving cycle). For city driving, the TH!NK Ox will be able to travel even further on a full charge, to over 250km. The platform concept also forsees a sports version with a higher top speed and a range extended to up to 450km, a range also relevant for the taxi version.

Easy charging Charging the TH!NK Ox from zero to a fully charged state from a standard 230V/16A European outlet, will take approximately 12 hours using the on-board charger. The Lion batteries can be charged to 80% capacity in less than an hour with a high power off-board fast charger.

As with all TH!NK vehicles, TH!NK Ox can be charged at any normal power point.

TH!NK Ox expressive front grille houses the charging point at a comfortable height, with a pull out cable that fits any normal appliance socket.

Think design

De wagen heeft een energie verbruik van 145 Wh/km. Dit is vrij hoog als je dit vergelijkt met andere elektrische auto’s. Dat zie je vaker bij auto die niet van de grond-af ontworpen zijn om elektrisch te rijden, de zogenaamde conversie modellen. Echter in vergelijk met een benzine auto is het nog steeds veel voordeliger. De prijs per km is 0,145 kWh x 23 euro cent = 3,34 euro cent. Het volgooien van de “tank” kost 16 kWh x 0,23 euro = 3,68 euro. Met volle accu’s kun je 110 km ver rijden. Met elektrisch rijden kun je dus veel geld besparen op jaarbasis.

DNA key-less entry

TH!NK Ox has a key-less entry fob setting that stores and displays the personal choices of the user. When entering the vehicle, your personal desktop, music and for example, e-mails are displayed. Seating position, mirrors and steering wheel are automatically adjusted to suit the user. The DNA-key gives the user feedback on charging status and sends messages, for example, for pre-heat or pre-cool options via GPRS.

The connected car

TH!NK Ox is highly connected, featuring real time navigation, web, e-mail and open source interfaces, intelligent and sustainable driving and route calculations. TH!NK Ox features the TH!NK connectivity platform to enable drivers and passengers to stay tuned at all times. The system also keeps track of the battery performance and allows remote diagnostics at all times.

Always connected

The TH!NK connectivity platform will be built on a fully functional computer. The system will be capable of bringing the power and experience of rich Internet applications into the car, enabling the creation of a whole new genre of smart applications. The combination of GPS and constant Internet connection provides an incredible platform for location-based search, and location-based services adapted to the vehicle.

Location-based services

Drivers will not have to waste energy or time hunting for a parking space: the system will display available parking spaces at the destination, or along the route, provide guidance to a free space, identify and choose a suitable space and even pre-reserve a suitable space for them.

“Clean tech” location-based services will help drivers locate critical services such as charging stations or standard electric outlets where the TH!NK Ox can recharge. We envisage these “public” outlets as being provided by employers, municipalities, shopping centres and universities.

Assessing both the car and the driver

TH!NK connectivity may also give drivers feedback on their driving behaviour and guidance on optimising energy usage by providing real time energy consumption information while driving. In real time, the navigation system will graphically display how far the car can go one-way, given the current battery charge level, how far the car can go round trip, and how much battery charging time is required to reach a specific destination. Additional examples of EV integration will include smart energy usage, giving the user the ability to remotely request that the vehicle be pre-heated or pre-cooled while still plugged into a power outlet, via the Internet or a mobile phone.

Green power management solutions

In conjunction with selected utility partners, the system will enable “demand side management” by charging during off-peak times, or allowing the utility the option to modulate charging during peak hours. This way, the vehicle will charge during the least expensive, lowest-demand and “cleanest power” time periods, reducing the strain on the electricity power network. The system will also enable vehicle-to-grid (V2G) applications, enabling the “time shifting” of electrical power, energy and carbon credit markets and new “green power” initiatives.

Infotainment and telematics solutions

The telematics system will include an integrated dual audio amplifier with spatial expansion to enhance the space inside the car. Audio and video player applications will provide the entertainment options that drivers and passengers expect from modern cars.

A help button with GSM voice respond will enable drivers to reach the TH!NK Service Desk for assistance. Both on-board and off-board computer systems will monitor critical car functions and will notify the driver, the owner and the service stations of any abnormalities.
