CITY CAR: This is a live design project for 2014, leading to smart cars for smart cities of the future. This prototype uses the built-in Bluebird™ energy cartridge exchange system that is compatible with a proposed design of service station, the details of which cannot yet be disclosed for legal reasons.

 

 

TITLE: SMART CITIES SUSTAINABLE TRANSPORT INFRASTRUCTURE SYSTEM

 

 

PATENT ABSTRACT

 

An electric vehicle rapid recharging system using a universal format (loading method, locking mechanism and contacts) of energy cartridge that is compatible with battery and fuel cell technology and a design of service station for such universal cartridge that is economical to install and operate, thus providing the basis for a cost effective and sustainable infrastructure for zero pollution vehicles internationally, by way of a cornerstone for smart cities and communities.

 

 

PATENT DESCRIPTION: SMART CITIES SUSTAINABLE TRANSPORT INFRASTRUCTURE SYSTEM

SUMMARY or OBJECT OF THE INVENTION 


It is the object of the present invention to provide a solid foundation upon which the infrastructure for sustainable cities of the future may be developed ....

BACKGROUND FIELD OF THE INVENTION 

The present invention relates to electrically propelled vehicles that are not tethered and so require an energy storage system upon which to draw, to enable such a vehicle to travel a practical distance as necessary for the operator.

 

Typically, the range of a vehicle from any given size of battery bank or cartridge is dependent upon the physical dimensions of the cartridge and the energy density of the battery chemistry.

 

In the last 30 years significant investment in research and development of batteries has focused on improving energy density, whereby, there was a transition from lead-acid, to nickel-cadmium, to nickle-metal-hydride, to lithium-ion, and so on, with research continuing apace as to more energy efficient (dense) chemistry.

 

CHEMISTRY

 

We are not concerned here with the chemistry of the storage medium. We are concerned with compatibility and interchangeability, such that upgrades in the chemical delivery system is flexible, but still remains compatible with a universally acceptable infrastructure, without which the spread of sustainable transport will take far longer than it need be, so prolonging dependence of burning fossil fuels that are considered to be responsible for global warming and the generation of carcinogenic airborne chemicals.

 

The most common method of recharging an EV is via a plug from a convenient charging location. To get away from the usual 4-8 hour charge time, fast-charge charging points are being introduced in Europe and the USA. The problem with fast charging points is that they still take a long time to recharge a vehicle, long enough that fast charging is not compatible with the speed of city life.

 

NETWORK DEMAND

 

The other problem is that there is and will be greater demand for peak generated power if roadside or pavement charging becomes popular. As such that will require additional output from electricity generating stations, perceived as another global warming issue. If follows that if this situation is not addressed in the design of EVs and EV service facilities, that the move to zero emission transportation will not be as successful in halting climate change as politicians and voting citizens now require, but will simply move the problem sideways, rather than dealing with grass roots strategy.

 

LOAD LEVELING

 

A means of keeping electricity generation at or near to its present capacity is a desirable feature in the move toward sustainability, where utilities need to run efficiently in order to make profits, but also to provide energy with the minimum of pollution. .......

DISCUSSION OF THE BACKGROUND ART

Cars, vans and larger commercial vehicles, especially buses, have been fitted with batteries as a removable unit, or cartridge. This idea is not new and goes back to 1910-1920 with Porsche producing such a system where vehicles had a spent cartridge removed from the underside of the vehicle by a jacking system, lift or hoist.

 

More recently from 2011, Shai Agassi improved on the concept employed by Porsche with his Better Place company building service stations compatible with the Renault Fluence. These service installations swapped battery units from underside the vehicle using subterranean (below ground level) machinery.

 

In the US, Tesla are also using a similar but improved system to that developed by Better Place in terms of exchange speed, to swap battery cartridges on their model S sedans (for example). Speed of cartridge exchanges is therefore of considerable importance and may now get more attention with Formula E racing coming on stream. ......... 

 

The fastest battery cartridge exchange was, before this present invention, by a converted Rover (Metro) which used two electric motors running at 36 volts to drive its lifting mechanism via gearing and levers to raise a cartridge from the ground until it contacted with the vehicle's chassis and locked in place, also making electrical contact. This process took around 50 seconds, with additional, but far less time to unload the spent cartridge beforehand and relocate. This year (2014) Tesla has demonstrated their battery pack exchange system timed at about 90 seconds using a below ground (below vehicle) automated (or semi-automated) installation.

 

The problem with the Better Place and now Tesla systems is that the complexity and hence cost of the station that is designed to services a customer's vehicle, is a major stumbling block to popularizing the concept.

 

In addition, the vehicles that may be serviced by the Better Place or Tesla (BPT) systems are designed to use their own cartridge format and these are different in configuration, hence not interchangeable, but rather encourage brand loyalty.  .......... They are not compatible with more than 95% of vehicles currently in production ......

 

AUTONOMY

 

BPT style systems leave consumers entirely dependent on service stations for instant energy replenishment, via cartridge exchange, there is no half way level of autonomy as regards cartridge servicing, such that a vehicle might refuel itself without the need for additional equipment beside a road or perhaps with the help of an AA or RAC or other roadside assistance service such as Green Flag, who might carry a spare cartridge for customers as part of their repertoire of recovery services.

 

It would though be a significant advance for electric vehicles if they could look after their own needs by virtue of  ......

 

ADOPTION

 

BPT style systems do not cater for gradual acceptance and introduction where a vehicle might be serviced at local depots without the aid of any external machinery. .......

 

A local depot might be any arrangement with a shop or supermarket to carry stocks of universal cartridges .......

 

 

A conceptual 3.6 megawatt service station for smart cities of the future

 

LOAD LEVELING:  We cannot reveal the (proprietary) inner workings of our design for low cost service stations of the future, but this drawing is to scale, showing that the system we should like to develop for smart cities is a practical proposition for most vehicle sizes on the road today.

CONSULTANT eco-engineer and patentee: N'Jay is donating his time to various conservation projects on a free-basis, with fingers crossed for a cleaner planet and sustainable energy for all. He is an expert on battery exchange/storage strategy. He also has a number of (Town & Country Planning) application/appeal victories under his belt - useful when it comes to smart cities of the future when his experience negotiating with officials could be useful. His father was a major roofing contractor for the GLC (now GLA) in the 1970s, building affordable quick-build houses in the UK, Africa and Indonesia - that were also rot proof with high insulation factors: way ahead of their time.
