Smith Electric Vehicles re-launch Zero-emission Commercial Vehicles

Smith Electric Vehicles are a little-known company from the North-East of England that has an extensive history of electric vehicle production. For over 70 years the company has been developing electric milk floats and lighter weight vehicles. In the early 2000's the company made a launch into commercial vehicles (CV's), and may set a new standard for electric CV's - while bolstering a homegrown industry.

Though unfortunately Smith Electric had to pause its operations in 2014 due to low market demand (a consequence of being an early innovator), with market demand for EV's now steadily growing, it is developing a strategy for a strong comeback.

Smith Electric says the fully electric, zero emission CV's are best suited to inner city, localised operations, where emission zone fees are highest, and the journey distances can easily be met by battery range. The company’s two main product lines, the Newton and the Edison, come in a range of sizes, from 7.5 tons to 12 tons.

Their current battery ranges are between 30 and 120 miles, depending on the battery chosen and route requirements. One down side is charge times can be as long as 8 hours for larger batteries.

Smith have been able to optimise battery range by drawing on extensive data it has collected through its many years of operation. With over 13 million miles covered by their trucks, global sales manager David West claims; “Nobody has more expertise, more trucks, or more mileage.” Every component on a Smith vehicle was designed and developed by the company, achieving a highly-integrated design.

Smith offers a prior assessment service with which they record and analyse a customer’s typical duty cycle and conditions, to then match the optimal size and type of battery for their needs. In doing so they ensure no unnecessary weight is added while matching capacity.

The company is preparing an innovative production model with decentralised, local manufacturing hangars in European centres where it intends to do business.

This local assembly model has two key benefits. First, the components for trucks are sent un-assembled from the US greatly reducing their size in shipping. As Freight in the City Magazine reports; ‘The new hangars will enable one container to ship out enough components to build 20 vehicles at a local destination’, achieving financial and carbon savings.

The local hangar approach also means the skills and facilities for repair services become embedded in the local area, which not only improves customer experience and trust, but contributes to regional industrial development. Smith hangars are planned for the North-East, London, Norway (where the EV market is expected to boom thanks to legislation requiring all vehicles to be emission free by 2020), Sweden and Denmark.

Adoption of Smith trucks and other E-CV's is getting a helping hand from the government’s Plug-in Van Grant, that provides a 20% discount on new purchases - bringing Smith’s £96,000 trucks to less than £75,000.

As of February 2017, due to funding issues the company is still waiting to launch its new strategy, but they remain confident that demand is nearly sufficient, with an expected launch sometime during 2017.

A widespread uptake of electric commercial goods vehicles will surely be welcomed by all urban residents, with these large diesel engines being some of the largest contributors to urban air pollution.

Autonomous Prototypes are Hard at Work

As the push towards cleaner energy vehicles continues across Europe, with low emission zones that ban polluting road vehicles in use across many European cities, and likely to spread to include off highway vehicles as well, the question must be asked; can technology keep up?

Dr. Mark Settler has used data from 1400 vehicles to try and answer this question. Considering mainly the question of combustion engines, Settler argues that while in rural areas, as diesel engines are significantly more efficient, standards can be met. However, there is an additional challenge in urban areas as diesel emissions, while better for the environment, are worse for human health. This challenge must result in a push towards electric and hybrid vehicles in highly populated areas.

Dr Peter Harrop argues that a push towards electric vehicles is best in all areas, with the end goal of totally energy independent vehicles. In China, a technology company has developed four totally solar panelled cars, and contactless charging of electric vehicles may be closer than we think. Many have also had the idea of swarms of smaller vehicles performing tasks that would traditionally be done by one vehicle, an idea that could be made possible by autonomous technology. Harrop doesn’t argue that all these changes will come all at once however, he instead suggests that by gradual developments in sophisticated electrical components.

As governments are starting to increasingly take note of the dangers of diesel engines, it is imperative that companies start to move towards alternative technologies now, as sudden changes in legislation can cripple companies if they are not adequately prepared.

UPS begins testing Hydrogen fuel-cell Delivery Truck

The first prototype of a fuel cell delivery truck from UPS is to be deployed in Sacramento this year. The truck contains a hydrogen cell powered power train, with converts compressed hydrogen gas to electricity, powering a 45kWh battery which runs on 10kg of hydrogen fuel.

Some other hydrogen powered vehicles use other energy to power some features, whereas hydrogen totally powers this truck. This move is just the next in a long line of developments that attempt to reduce emissions from delivery vehicles; the only by-product of these vehicles being water.

The vehicle will be deployed alongside additional trucks, in the California area, as this is the only place with enough existing hydrogen infrastructure. The trucks will need to be refuelled roughly every 125 miles.

The project was partially funded with a 2013 grant from the Department of Energy, which focuses on hydrogen fuel-cell technology in commercial delivery vehicles.

Focus on Engineering "Habits of Mind" to Produce more Engineers

A recent study from the Royal Society of Engineers with TES has found that a less discipline bound method of teaching could be essential for equipping students with the skills necessary to succeed in engineering. Engineering makes up 20% of the UK’s gross value and is currently facing a massive skill drain, with not enough students going on to study at a higher level.

The study found that rather than the traditional model of focusing on STEM subjects: science, technology, English, and maths, to encourage budding engineers, a different model, STEAM which includes a focus on art and design subjects is needed as well.

It identifies that the way to develop the “habits of mind” which are needed by engineers, and include problem solving, visualising, and adapting, is to move away from strict disciplinary style teaching and instead use exercises involving playful experimenting and engagement with engineers.
