Swedish city orders electric bus with CCS charging
Heliox, a manufacturer of power conversion equipment, has delivered its CCS 700 V charger to fellow Dutch firm VDL Bus and Coach. VDL’s Citea electric bus will be joining the fleet of Swedish transport operator Byberg & Nordin. Heliox says this will be the first European e-bus to use the Combined Charging System (CCS) standard…. Read more »
UK startup improves free piston linear technology, generating power with no drive shaft
A free piston linear power generator (FPEG), which uses combustion to generate electricity directly, using no drive shaft, could provide an EV range extender that’s far smaller and more efficient than a legacy ICE. Several research groups, including a Toyota R&D team, are investigating this intriguing technology. UK startup Libertine LPE has developed an FPEG… Read more »

Pushing the power limits: Fuji Electric on the new requirements of power electronics
With each passing model year, the requirements demanded of automotive power electronics increase. Market forces are pushing Insulated Gate Bipolar Transistor (IGBT) modules towards lighter, smaller, more powerful and more reliable technology. These switching devices are what power an EV or hybrid inverter, and with increasingly stringent emissions requirements, automakers are looking for more innovative… Read more »
ZeroTruck: Electric fleet vehicles offer compelling cost savings
Medium-duty trucks make perfect candidates for electrification, and the market would seem to be full of opportunities for small companies that build powertrains and components. It’s treacherous territory, however – several startups targeting this space have foundered. ZeroTruck founder Tedd Abramson told Charged about his company’s strategy to hang on for the long haul. Abramson… Read more »
New design combines traction motor with AC compressor, saving space and energy
Scientists from Nanyang Technological University (NTU) and the German Aerospace Centre (DLR) have invented a 2-in-1 electric motor that integrates the vehicle’s traction motor with the air conditioning compressor, saving both space and energy. “The biggest challenge with electric cars in tropical megacities is the range that they can travel on a charge, because their… Read more »
Infineon to acquire International Rectifier, pioneer in wide-bandgap semiconductors
Infineon Technologies (OTC: IFNNF), Germany’s largest chipmaker, will acquire California-based International Rectifier (NYSE: IRF) for $40 per share in a $3 billion deal. International Rectifier specializes in power-management semiconductors. Particularly attractive to Infineon is IRF’s expertise in gallium nitride on silicon (GaN) semiconductors. According to Bloomberg, the acquisition will solidify Infineon’s position in GaN discretes… Read more »
A closer look at the semiconductor switch
In this article I’ll be giving an overview of that most important of power electronics components: the semiconductor switch. I’ll first address what a switch is, and then delve into some of the more important compromises and shortcomings that exist in real-world switches that engineers must contend with when designing chargers, motor controllers, DC-DC converters… Read more »
Beijing to deploy 1,000 DC fast chargers, require new residences to install chargers
Authorities in smoggy Beijing are keen to encourage what they call “new energy” vehicles, but at present the city has few public charging stations – the 60 or so that exist are reserved for buses and taxis. A new plan aims to change that, requiring new residential communities in the Chinese capital to install chargers… Read more »
