The impact of national environmental policy on the global success of next-generation automobiles
In this paper, we identify the most crucial factors of the potential world market success of alternative car designs: fuel cell vehicles (FCVs), hybrid electric vehicles (HEVs), battery electric vehicles (BEVs), and conventional fuel efficient vehicles (FEVs). We assess which vehicle concept is favoured under which regulation regime. We suggest that the global success of a certain technology ...

Comparison and evaluation of different DC/DC topologies for plug–in hybrid electric vehicle chargers
The battery charging system is a critical part of a plug–in hybrid electric vehicle (PHEV). The efficiency, charging speed, and cost of such chargers are crucial to the commercialisation of PHEVs. In this paper, the advantages and drawbacks of four potential PHEV charger topologies were compared based on their operations through simulation and experiments. Their electrical stress, efficiency, ...

A new life estimation method for lithium–ion batteries in plug–in hybrid electric vehicles applications
This paper presents a new approach to life estimation for lithium–ion batteries used in plug–in hybrid electric vehicles (PHEVs) applications. A new framework for battery life estimation is developed which investigates the effects of two primary factors of battery life reduction in PHEVs applications, namely, depth of discharge (DOD) and temperature (Tbatt), under typical driving conditions, ...

The battle of batteries: a history of innovation in alternative energy cars
The paper gives a global view on the historical development of electrical cars. It is a history described in five major waves; the first one starting about 1835 and the last one ending about 2000. With two cases, important aspects of the two last waves are described in detail. The cases are the French VEL car and the Norwegian Think car. They have had their more specific setbacks. Problems in ...

Coulombic Efficiency Demystified
Let’s say you have a 1-liter bottle of water and you pour all of its contents into another empty 1-liter bottle and then back to the original bottle. A few drops of water spill as you do so. The loss is hardly noticeable - the drops may account for only 1% of the total, so you still have 99% of the water that you started with. This example essentially illustrates Coulombic efficiency - the ...

Moixa R&D for Vehicle-to-Grid technology - Case study
In spring 2018, Moixa joined a consortium of leading energy and transport companies on a study – V2GB – Vehicle to Grid Britain – into how to reward drivers who use their electric vehicle (EV) batteries to support the grid. Vehicle to grid (V2G) technology will play a vital role in supporting the grid as it faces rapidly growing energy demands, by allowing millions of ...

Designing a sustainable hydrogen energy economy
A general vision of a sustainable energy economy relying substantially on hydrogen produced from renewables is sketched as a potential solution to the twin global crises of climate change and depleting oil reserves. Core differences between this 'sustainable hydrogen economy' (SHE) and the original hydrogen economy (HE) proposed in the early 1970s are discussed. In transport, rather than posing a ...

LITHIUM-ION BATTERY RECYCLING
The energy sector has turned to alternative vehicles due to reasons such as the increase in the number of vehicles in the world, rapidly decreasing oil resources, wars, and increasing pollution rates all over the world. Electric vehicles that developed for this purpose, have come to the fore in the production sector because their pollutant emissions are lower than conventional vehicles and they ...

Major EV Battery Safety Recalls? Electra`s AI Technology Can Help
Electric vehicle recalls have accelerated as the risk of battery thermal runaway due to faults and failures remains a major pain point in the eMobility industry. General Motors recently took a $1.8 billion hit for battery warranty and replacement costs for the Chevrolet Bolt, according to CNBC, and it is not the only major OEM challenged by battery malfunction. While thermal runaway in electric ...

9 Benefits of Electric Trucks, are they the future?
The HGV industry clearly has to move away from using fossil fuels (as does everybody else). Currently, the main potential replacements for it are electricity and hydrogen. If hydrogen is used, however, it is likely to be in combination with electricity. This is because electric trucks have a range of specific and meaningful benefits. Here are just some of them. Electricity is relatively easy to ...

Smart Energy Islands, global test-bed for batteries - Case study
A £10.8 million project on the Isles of Scilly will provide a model for electric vehicles and home batteries to play a major role in low-carbon smart energy systems around the world. Moixa will develop platforms allowing electric vehicles and smart home batteries to be used to help balance supply and demand within the islands’ energy system, although the project will not fund the ...

A Michigan Smart Energy Code
There’s been a lot of controversy about the Green New Deal. While we like some of the “big” ideas in the plan, there are many other smaller, less news-worthy ways that can readily enhance energy sustainability. One way is for individual states to make sure that their building code makes it easy to incorporate new energy innovations. Why? There’s no question that ...

Ceramics 101: The QuantumScape Separator in Context
QuantumScape’s solid-state lithium-metal battery technology is enabled by our proprietary ceramic solid-electrolyte separator. While you may be familiar with everyday examples of ceramics, like a coffee mug, high-tech ceramics are likely less well-known. In this blog, we’ll review the basics of ceramics – what they are, how they’re made, how they’re used – and ...

What is Thermal Runaway in Lithium-Ion Batteries?
Thermal runaway is a violent chain reaction of exothermic chemical reactions resulting in an uncontrollable increase in system temperature. Now, where does this reaction might unfold? Batteries and energy storage systems, which are integral parts of tech around us, are the main stage for this drama. They sometimes fall victim to thermal runaway, turning a peaceful power source into a potential ...

Hitting the Trail with the Sun Behind Us
On October 11, 2019, a group of people gathered at the new Welcome Center for the start of the first solar tour by bicycle in the historic downtown district of Titusville, Florida. Titusville is located on the Indian River across from Kennedy Space Center. Creation of this bicycle tour brought together several themes, showcasing local examples of renewable energy for sustainability, past ...

There’s a new contender in the quest for the next superbattery
It’s been nearly 40 years since the battery world had a major shake up. In 1980, a researcher at England’s University of Oxford made the first breakthrough that would eventually take lithium-ion batteries from theoretical to possible. But the industry was slow to embrace the shiny new design. It would be more than a decade before Sony decided to throw its weight behind lithium ion, ...

A Few Things You Should Know about Carbon fibers
Carbon fiber is a new type of fiber material with high strength and with a carbon content of more than 95%. It is a microcrystalline graphite material obtained by piling up organic fibers such as flake graphite microcrystals along the fiber axial direction, and then undergoing carbonization and graphitization treatments. Carbon fiber is a new material with excellent mechanical properties. Its ...

Subsidy reform to power U.S. clean tech
Clean tech in the United States has been on the rise in recent years— even through the recession and other challenges. Increasing wind power, falling solar costs, expanding electric vehicle markets, government stimulus and other investments have built a global clean tech sector that topped $263 billion last year. In the first quarter of 2012, however, global clean energy investment dropped ...
