Showa Denko has developed a second generation high-grade silicon carbide (SiC) epitaxial wafer (HGE-2G) suitable for power semiconductors. SDK has been mass-producing the first generation of high grade SiC epitaxial wafer with very low defect density under the trade name of 'High-Grade Epi' (HGE). HGE-2G achieves further improvements in quality with six inches (150mm) diameter.

Tritium has signed a deal with BOX ENERGI to be the sole supplier of DC rapid chargers for sites across the United Kingdom for its DRIVE ENERGI network. DRIVE ENERGI is targeting to complete the installation of 2,500 charging locations by 2025, with at least 100 sites to be live by end of January 2020.

As the automotive industry seeks to electrify its product ranges, the thermal management of high capacity batteries used for EVs is proving a significant challenge. The performance and efficiency of battery cells can deteriorate - and their ageing can be accelerated - if operating temperatures exceed the upper or lower limits of a comparatively narrow range. In extreme cases, exceeding upper operating limits can risk thermal runaway of cells, lea...

It is nonsense to forecast pure electric cars costing the same as traditional ones, then life continuing much as usual. The up-front price of pure electric PE cars will be dropping below that of internal combustion engine ICE ones around 2025. The fundamentals are now clear. By Dr Peter Harrop, industry expert and Chairman at IDTechEx.

UnitedSiC has added two new TO220-3L package options to its growing range of hard-switching UF3C FAST series of 650V SiC FETs. The new products offer RDS(on) values of 30mohms (UF3C065030T3S) and 80mohms (UF3C065080T3S). The three-leaded, industry-standard TO220-3L package features enhanced thermal characteristics made possible by a sintered-silver packaging technology.

A new technology that could see tyres generate electricity whilst driving is being developed by engineers in Japan. Falken’s parent company, Sumitomo Rubber Industries, together with Professor Hiroshi Tani of Kansai University, have developed the Energy Harvester that takes advantage of the build up of static electricity, known as frictional charging, to produce power efficiently as the tyre turns.

Faster charging of electric vehicles demands efficient power delivery while keeping people safe. This video can help you to improve the efficiency, reliability and safety of your EV charging system with Littelfuse products.

AIWAYS, the Shanghai-based personal mobility provider, has embarked on what is believed to be the longest point-to-point drive of a prototype electric vehicle ever attempted. A pair of prototype AIWAYS U5 battery-electric SUVs departed yesterday from Xi’an in China, and are now being driven 14,231km (8,843 miles) to Frankfurt, Germany. The vehicles, which are nearing the end of a comprehensive test and development program, are schedule...

According to a survey commissioned by VOOM, the world’s first on-demand, telematics-based insurance platform for specialised mobility, 49% of millennial e-scooter riders are concerned about harming themselves or others when riding; but 53% have never thought about purchasing insurance coverage. VOOM’s findings emphasise riders’ lack of awareness regarding the potential physical and financial danger they put themselves in when us...

In electric vehicles, China is not what it used to be. Electric bike demand collapsed five years ago, and electric bus demand followed two years ago. With electric buses, the reason was entirely a precipitous drop in government financial support of demand and production, the peak being accentuated by pulling forward to grab subsidies while there were available. In 2020 they will be zero but despite this, in 2027 China plans that full electrificat...
