BYD sold more battery electric vehicles than Tesla globally in 2024 and extended that lead in 2025. The company's technology — Blade Battery, e-Platform 3.0, in-house semiconductors — is genuinely competitive. What's keeping it out of American and European driveways isn't product quality. It's tariffs.
The first significant wave of end-of-life EV batteries is arriving. Redwood Materials, Li-Cycle, Umicore, and others are competing to build the closed-loop supply chains that could reduce EV battery dependence on Chinese material processing — but the technical and financial challenges are harder than the pilots suggested.
Electric vehicles cost significantly more to insure than comparable internal combustion engine cars in most markets, and the gap has widened rather than narrowed as EVs have become mainstream. The reasons are structural — repair costs, parts availability, battery uncertainty — and some are only now being addressed by the industry.
There are now over 5 million used electric vehicles on the market in the US alone. Battery health is the central concern for buyers — but the data on real-world degradation shows the anxiety is often worse than the reality. Here's what the numbers actually look like, and how to evaluate a used EV properly.
After a decade of 'five years away' promises, solid-state batteries are finally moving from lab demonstrations to small production runs. Toyota, QuantumScape, Samsung SDI, and CATL each have real hardware. None of them have solved manufacturing at scale. Here's what's been demonstrated, what's still promotional, and when consumers will actually see these cells.
The US has doubled its public fast-charging footprint since 2022 and the North American Charging Standard is consolidating the industry. But uptime rates at public chargers still lag far behind what EV drivers need — and solving reliability is harder than building more stations.
Toyota, QuantumScape, Samsung SDI, and Solid Power have all announced solid-state battery production timelines. The technology genuinely promises higher energy density, faster charging, and better safety. The gap between lab results and mass production is where every timeline has collapsed — and the 2027-2028 window is the most credible yet.
Electric trucks arrived with a bold promise: they wouldn't just replace gas-powered pickups — they'd outperform them. More torque off the line, lower center of gravity, and enough power to make a V8 feel obsolete. Two years into real-world volume sales, the scorecard is more complicated than either camp predicted.
Vehicle-to-grid technology lets electric vehicles discharge stored energy back to the home or the power grid. The Ford F-150 Lightning can power a typical American home for 3 to 10 days. Electric school buses in Delaware earned over $9,000 a year selling grid services. Maryland passed the first US comprehensive V2G interconnection rules in July 2025. The question is no longer whether this works — it's whether the economics add up for individual owners.
Tesla's 4680 cylindrical battery cell has reached 350 Wh/kg gravimetric energy density in production — the original target from its 2020 announcement. The path from prototype to that number reveals how hard battery manufacturing actually is at scale.
After a decade of promises, solid-state batteries are arriving in limited commercial volumes in 2026. The production ramp-ups from Toyota, Samsung SDI, and QuantumScape involve very different chemistries, cost structures, and target markets — and not all of them will reach drivers at the same time.
Toyota says solid-state EV batteries arrive in 2027-2028. QuantumScape is in automotive qualification. Solid Power just shipped cells to BMW and Ford. The technology is real, the obstacles are specific, and the timeline slippage has a traceable cause that finally appears to be resolving.
