As OEMs solidify their commitment to reduce their carbon footprint, their focus is on electric cars which reduce carbon emissions, cut oil use, and provide an improved driving experience. Alongside vehicle development is significant advancements in battery R&D, vehicle-to-grid connectivity, and wireless charging.
As the most critical part of an electric car, vehicle batteries are guaranteed to last at least 100,000 miles (160,000 kilometers) on average before they no longer hold enough of a charge and have to be replaced. Here’s what happens to many of them.
Empa researcher Cristina Dominguez is developing a computer model, which can be used to plan electricity grids in developing countries. To collect data, she travelled to Kenya to get an idea of how people live without electricity and what developments access to the power grid can trigger.
While security is front of mind when it comes to connected and autonomous vehicles, little consideration is given to security the risks associated with electric vehicle (EV) charging stations. Research demonstrates that EV charging stations can be a conduit for DDoS attacks, ransomware, theft of ID, and could jeopardize the security of the power grid.
As electric vehicles become more commonplace, charging stations and networks will undergo substantial changes. For example, business owners of EV charge points may need to upgrade their equipment to permit faster charging times.
The chip shortage has already been causing concern in the automotive industry for months. These were further exacerbated by the fire at the Japanese chip factory Renesas. But the date for the resumption of production provides a ray of hope.
The power factoring correcting (PFC) converter does not often get a lot of love or attention. For low and medium power levels (let’s say up to 1000W or so), a suitable reference design is often copied and then little time is budgeted for testing and proving it. Yet this part of an AC-DC power supply unit (PSU), is the base for the rest of the design.
Cambridge GaN Devices (CGD), a University of Cambridge fabless semiconductor spinout company that was founded in 2016 in Cambridge’s Department of Engineering, has raised a substantial amount of funding to expand its GaN-based product portfolio and double its staff count.
