Five technical challenges for battery pack end-of-line test stations

Sponsored by Chroma The emerging growth of the EV market has created significant challenges to battery manufacturers on how they test and validate the functionality of battery modules and packs effectively and efficiently, especially during high voltage tests. It is also critical while manufacturing to adhere to associated test standards and regulations during the test phases.  The four primary test phases with associated test functionalities and systems: Sub-Module Welding Test: Quality verification on welding for the battery sub-modules Module-level End-of-Line (EOL) Test: Functional verification for the individual battery modules under a systematic test  Automatic Test System (ATS) for module-level In-Line...

Qorvo says its new SiC FET product line has best-in-class figures of merit for on-resistance

Radio frequency technology company Qorvo (formerly UnitedSiC) has announced a new SiC Field Effect Transistor (FET) product line, which it says has best-in-class figures of merit for on-resistance. The FET is designed for the 800 V bus architectures in the onboard chargers of EVs as well as industrial battery chargers, industrial power supplies, DC/DC solar inverters, welding machines, uninterruptible power supplies and induction heating applications. The UF4C/SC is a 1,200 V FET product line. “Expanding our 1,200 V range with higher-performance Gen 4 options allows us to better serve the engineers who are moving their bus designs to 800 V,”...

New research looks at the economics of aluminum for EVs

Research commissioned and funded by The Aluminum Association’s Aluminum Transportation Group has studied the content and economics of aluminum in EVs. In a White Paper, authors from FEV Consulting, Novelis and Constellium found that current BEVs have a higher aluminum content than comparable ICE vehicles and that aluminum content rises as EV size and performance rise. “Despite expected improvements in battery cost and storage density, aluminum lightweighting solutions are expected to remain economically attractive for at least the next decade,” the authors write. “Lightweighting battery-electric vehicles with aluminum provides additional economic benefits when the entire sales fleet is considered, creating...

Foxconn about to start Electric Vehicles.

Taiwan tech company Foxconn about to start Electric Vehicles. in a few countries like Europe, India, and Latin America, as well as indirectly coordinating with German automakers chairman Liu Young-way said O Wednesday. Foxconn, the world’s largest assembler of iPhones, is planning to make a foray into the electric vehicles business, on Monday by revealing three concepts of Electric vehicles, and these include the model C SUV and the Model E sedan which looks like racing-car level acceleration with the range of 750 km per charge. At the same time they also revealed Model T bus which gives a range...

In-wheel motor co-developed by Lightyear and Elaphe reaches 97% energy efficiency during testing

Solar EV company Lightyear says the EV powertrain it has co-developed with in-wheel-drive technology company Elaphe is the most efficient production EV powertrain in the world. Lightyear says, “we’ve achieved an efficiency of 97% from the in-wheel motors, losing just a fraction of energy through heat.” The in-wheel motor relies on a modified version of Elaphe’s proprietary electromagnetic layout, is currently being tested as part of the final steps of Elaphe’s design and validation methodology, and will be produced at Elaphe’s facilities in Slovenia. Lightyear plans to install the motors in all four wheels of its forthcoming Lightyear One solar...

InoBat and Green Lithium to establish large-scale lithium refinery in the UK

Battery supplier InoBat Auto and mineral processing firm Green Lithium have formed a strategic partnership to build and operate a large-scale lithium refinery in the UK. Green Lithium will supply InoBat with battery-grade lithium chemicals, and the two companies will collaborate to accelerate the development of a “cradle-to-cradle” UK battery value chain, from the provision of low-carbon lithium chemicals all the way through to the recycling of batteries. InoBat and Green Lithium will collaborate to work with governments in the UK and the EU to achieve their strategic business goals, including InoBat’s ambition to expand its presence in the UK...

Colorado provides $65 million for electric school bus grants

Governor Jared Polis of Colorado has signed SB 193 into law, providing $65 million for an electric school bus grant program. The state will award funding to school districts to help finance, purchase and maintain electric school buses, and to install charging infrastructure. New federal funding for electric school buses is available from the EPA’s Clean School Bus Program, part of the Infrastructure Investment and Jobs Act. By dedicating state funding for electric school buses, SB 193 will help maximize federal resources in Colorado. There are nearly 500,000 school buses operating in the US today, and they’re prime candidates for...

Mersen launches free online tool for designing bus bars

Mersen has introduced a free-access online tool for calculating the specifications of laminated bus bars. The Bus Bar Calculator is intended to support the design of bus bars in a range of different power converters. The new product relies on a physics solver developed by Gamma Technologies called GT-PowerForge to calculate the electrical, thermal and magnetic specifications of power converters and a frequential Modified Nodal Analysis to produce simulations. The Bus Bar Calculator can be used for a range of different design projects involving a wide variety of converter topologies, partial discharge test conditions and both SiC and GaN technologies....

cost of Electric vehicles are going to available for petrol vehicle cost.

The Union Minister of Road Transport and Highways Nitin Gadkari has mentioned that the cost of Electric vehicles are going to be available for the petrol vehicle cost and the statement was addressed at an event. Within a year Electric vehicles are going to be equal to the cost of petrol vehicles in the Indian market. Union Minister Nitin Gadkari explained that the central government is promoting green fuels in a big way. The cost issue is a serious one, mainly for the four-wheelers which are not under 10 Lakhs in the Indian market. Even options that do exist offer...

Ola’s first Electric car.

As we all know till today Ola has manufactured 2-wheelers ever since the first time Ola came up with its first electric car about to launch to the Indian market. At the Ola customer Day event held at Krishnagiri, Tamil Nadu announced its first electric car concept. Ola’s upcoming electric car looks rather futuristic with its clean front fasica and swooping roofline. It has twin U-shaped LED headlamps with an LED light bar in the center, while the rear features a slim LED light bar in the center, while the rear features slim LED lights that stretch across the width...
