I have a modest set of solar panels on an entirely ordinary house in suburban London. On average they generate about 3,800kWh per year. We also use about 3,800kWh of electricity each year. Obviously, we can’t use all the power produced over summer and we need to buy power in winter. So here’s my question: How big a battery would we need in order to be completely self-sufficient? Background Let’s take a look at a typical summer’s day. The graph is a little complex, so I...

Scientists have used a neat chemistry trick to tackle a major challenge facing future batteries. Their breakthrough paves the way for next-generation electric vehicle (EV) batteries capable of powering 500-mile (800 kilometers) journeys on a single, 12-minute charge. Lithium-metal batteries differ from standard lithium-ion batteries in that the graphite anode is replaced with lithium metal. These designs offer much higher energy density, the researchers said in a statement. For EV drivers, this...

On the face of it, these specifications imply that Xiaomi is re-using the display from last year’s Redmi Pad Pro, an IPS panel that also delivers 600 nits peak brightness. The Redmi Pad 2 Pro features a 25% larger battery though, which now totals 12,000 mAh. Unfortunately, wired charging wattages have dropped from 33 W to 27 W between the Redmi Pad Pro and Redmi Pad 2 Pro. The Redmi Smart Pen returns, as does a detachable keyboard that lacks a built-in trackpad. Similarly, the Redmi Pad...

You may remember that back in 2023 at the New York Auto Show, Ram announced its intentions to take on the Ford F-150 Lightning and, perhaps to a lesser extent, Tesla Cybertruck, with its own battery-powered pick-up. That was to be the Ram 1500 REV, but things have changed quite dramatically since then. Parent company Stellantis has had a change of CEO with big EV advocate Carlos Tavares leaving the company at the back end of 2024. Meanwhile, globally, EV demand in all sectors has stagnated, and...

John Hanson Pye/Shutterstock If you’re looking for affordable power tools to use on the worksite, or just to tackle some jobs around the house, Kobalt may be the best choice for you. Sold exclusively at retail level by Lowe’s Hardware, the blue tool brand features different battery options, including the 24V, which can be used in tools for quick and easy tasks. Kobalt’s 24V MAX lithium-ion batteries are great for simple tasks because they’re fairly small and not heavy. Th...

A charter plane is expected to repatriate about 300 South Korean workers who were among 475 arrested during a U.S. Immigration and Customs Enforcement raid at a construction site for an electric vehicle battery plant being built in Ellabell, Georgia. Photo by Erik S. Lesser/EPA Sept. 14 (UPI) — The United States’ second-most senior diplomat expressed regret Sunday over the recent immigration raid at a Hyundai car battery plant in Georgia.
