Dyson Electric Car Concept Main Innovations
The key developments in Dyson Electric cars are their batteries and its digital Hyperdymium brushless motors. Such techs are described in depth in the following articles. Sir James Dyson, Britain’s wealthiest man, invested £ 500 million on building the electric car to competitor Tesla’s electric vehicle. Dyson plans to apply the technical knowledge to the world in their electric cars.
The patent applications first disclosed the concept diagrams of the Dyson EV’s, showing a mono box hatchback with some off-road capability suggestion. This has also been confirmed by the patent filings as a seven-seater car with a three-row seat. Big diameter wheels have been pulled to the corners of the frame to make the car completely functional and better on rough surface. Please note that the Tesla Model X also provides 7 seat vehicle with higher speeds, but the Dyson electric car prototype claims 600 miles range.

1) Solid-state lithium ion battery in Dyson Electric Cars
Throughout the 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 Electric Cars 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 Electric Cars architecture – initially developed to sustain a lithium ion battery pack – will also be suitable with solid state batteries when it becomes cost-effective for future use in cars.
Solid state Lithium ion batteries – Safer than previous types of liquid electrolyte batteries
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 work was 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 lamination’s. Dyson wanted to market the car around the world and, unusually, China was at the top of the launching list. This may not be that shocking in view of China ‘s fantastic rise in one of the world’s biggest automotive markets.
