Dyson Electric Car Concept Main Innovations

The key developments of Dyson Electric cars are their batteries and its digital Hyperdymium brushless motors. Such techs are described in depth in the following articles.

1) Solid-state lithium ion battery

Throughout usage of lithium-ion technology a thin film of non-inflammable material replaced the pressurized liquid electrolyte, work as a separator, holding positive and negative electrode interaction components, and as an electrolyte, allowing for the movement of ions.

The battery design must have been flexible so that Dyson could market the vehicle at varying premium costs with various target ranges and a variety of battery sizes.

The company’s explanation of battery development is therefore most important. Dyson claims that the aluminium battery housing would not only make it easier to suit multiple battery sizes, but would also require ‘cell solutions’ without any big re-engineering modifications. This clearly indicates that the Dyson architecture – initially developed to sustain lithium ion battery pack – will also be suitable with solid state batteries when it becomes cost-effective for future use in cars.

The batteries of lithium ion usually operate at 35 ° C; expect complicated cooling, which is difficult for EVs, and fire has occurred both in the batteries of Tesla and GM. The batteries will never be completely charged or removed to prolong their operating life. But these problems do not affect solid-state batteries.

A lot of research works were performed by Dyson team. The battery pack was designed in an attempt to reduce weight and then become part of the integrated structure. A Dyson powertrain (usually the combinations of an electric motor, electrical inverter, single-speed transmission systems) energy was supplied by the innovative battery packs, and the entire power train was future-proofed by Dyson. The aluminium case of the battery pack would fit into several sizes and cell types to insure that any battery improvement can be rapidly executed.

2) Dyson’s digital electric motors

Dyson’s ‘switched reluctance’ digital motors are endowed with outstanding containers and superior mechanical design. They have great cooling techniques and better thermal efficiency – which is essential – whereas aerodynamically efficient, smooth and quiet rotors reduce losses.

A single speed transmission and a single power inverter will be the power pack of the SUV in a dyson – built electric motor. Each is fitted to a four-wheel (4WD) vehicle on each axle.

There is not much clearance space for Dyson ‘s digital brushless motors already it’s 90 + % powerful. In addition to the losses caused by electric fields in the rotor, it may face inertia and thermal challenges. Such losses are minimized with the usage of a variety of series laminations.

Dyson Sakti3 Solid State Li-ion Battery

The code nicknamed “N526” had a reported driving range of approximately 965 km on single charge utilizing Dysons patented solid-state battery technology. For contrast, Tesla, the American leader for powertrain cars, can travel up to 580 km with a single charge in a 7-seater Model X Long Range.

Dyson Solid State Battery

Thanks to its invention, solid-state Battery and $90 m (£69 m) purchase of the battery firm Sakti3, the Dyson car would have double the energy density and range of today’s EVs. The initiative by Professor Ann Marie Sastry from the University of Michigan makes the claim that lithium-ion batteries delivering over 400Wh / kg of energy density have been acquired in solid states.

Tesla Solid State Battery

It’s almost doubles the power of the Panasonic cells of Tesla, which are projected to be the world leader at around 240 Wh / kg. They essentially double the range of EVs while hopefully lowering the cost to $100 (£69) per kilowatt-hour. The point of reference at which EVs begin to bid for petroleum /diesel-driven cars on costs.

Problems were that since the invention of solid state lithium – ion batteries, the battery history filled with full of remarkable disasters, like failed Canadian company Avestor, which went bankrupt, after the solid-state lithium-ion batteries development, it sold to AT&T, where the batteries started to burst within U-Verse home entertainment sets. Therefore Sastry and Sakti3 (Sakti is Sanskrit for ‘power,’ whereas three is lithium’s periodic number) think that they have to cracked it, whilst others are struggling to grow.

Dyson Battery – Solid State Batteries for Electric Cars

Lithium-ion battery systems are normally filled with gels or liquids which can not store electricity, and it was the hope of Sastry that a ‘solid’ conducting substance was found that was sufficiently diffused to enable lithium-ions to move through the cathode, when discharge and charge the battery.

Sastry and her colleagues had therefore written simulation software a decade ago to categorize lithium combinations of materials and structures, leading to high-energy batteries that are affordable for mass production. If they are developed the batteries with hugely expensive to produce, they do not use this best energy density or the greatest number of cycles as a breakthrough .

The team of Sastry adapted second-hand equipment for printing foil crisp packets while installing the micro-thin layers of the batteries. In reality the same tested, in thin-film deposition method used in flat photovoltaic displays and solar cells lie micro-thin cathode films followed by the current collector, then the anode of the interlayer and so forth, all under vacuum. If the resulting cells are formed, they will be charged and tested. The major task is to extend the development of batteries from laboratory research to mass manufacturing.
