Innovation abounds in device charging

MIT Technology Review

No longer peripheral accessories, chargers today are more powerful, portable, and proactive. Consumers can look forward to rapid innovations in the coming years. The changes may be less perceptible than in smartphones, tablets, or wearables, but chargers have also been quietly reinvented over the last decade. At one time a bulky mix of tangled cables and connectors, slow to perform and prone to overheating, they're now smaller, safer, and faster, thanks to a slew of technological advances. These advances include a switch to gallium nitride (GaN), which has now usurped silicon as the preferred semiconductor, capable of handling higher voltages, faster switches, and more efficient conduction. Multi-port chargers, coupled with an industry-wide shift toward USB-C standardization, mean a single charger can handle multiple devices.

How BYD Got EV Chargers to Work Almost as Fast as Gas Pumps

WIRED

The Chinese automaker is racing ahead of global competitors--but don't expect to see those gains in the US anytime soon. Somehow, the whole thing got even faster. Earlier this month, Chinese automaker BYD announced that its Flash Chargers, first rolled out a year ago, can now charge some electric vehicle batteries from around 10 to 70 percent in five minutes, and from 10 to full in about nine. That's more than 600 miles of range in the time it takes to order a cappuccino and leave a nice tip. The new BYD chargers can add miles super quickly because they deliver up to 1,500 kilowatts (kW) per charge.


Should You Leave Your Phone Charging Overnight?

WIRED

Should You Leave Your Phone Charging Overnight? It used to be common wisdom that leaving your phone charging overnight degrades the battery. But handset design has evolved to mitigate the harm caused by constant charging. You may have heard that leaving your smartphone charging overnight--either plugged in or atop a wireless charger --can damage your battery. But is it actually harmful or dangerous to do that?


How Nissan improved the wireless charging pad for faster phone juice-ups

Popular Science

Using a magnet to connect the transmitting and receiving coils, electrons behave more consistently and the phone is less likely to overheat. Breakthroughs, discoveries, and DIY tips sent six days a week. In-car wireless chargers are notoriously finicky. Your phone can slide off the slippery charging pad at a sudden stop, or overheat and stop charging; the case can also prevent your phone from connecting. Often, it's a pain in the neck, not to mention an added distraction while you're behind the wheel.

Safe and Sustainable Electric Bus Charging Scheduling with Constrained Hierarchical DRL

arXiv.org Artificial Intelligence

Abstract--The integration of Electric Buses (EBs) with renewable energy sources such as photovoltaic (PV) panels is a promising approach to promote sustainable and low-carbon public transportation. However, optimizing EB charging schedules to minimize operational costs while ensuring safe operation without battery depletion remains challenging - especially under real-world conditions, where uncertainties in PV generation, dynamic electricity prices, variable travel times, and limited charging infrastructure must be accounted for . In this paper, we propose a safe Hierarchical Deep Reinforcement Learning (HDRL) framework for solving the EB Charging Scheduling Problem (EBCSP) under multi-source uncertainties. We formulate the problem as a Constrained Markov Decision Process (CMDP) with options to enable temporally abstract decision-making. We develop a novel HDRL algorithm, namely Double Actor-Critic Multi-Agent Proximal Policy Optimization Lagrangian (DAC-MAPPO-Lagrangian), which integrates Lagrangian relaxation into the Double Actor-Critic (DAC) framework. At the high level, we adopt a centralized PPO-Lagrangian algorithm to learn safe charger allocation policies. At the low level, we incorporate MAPPO-Lagrangian to learn decentralized charging power decisions under the Centralized Training and Decentralized Execution (CTDE) paradigm. Extensive experiments with real-world data demonstrate that the proposed approach outperforms existing baselines in both cost minimization and safety compliance, while maintaining fast convergence speed. Recent advances in sustainable transportation have emphasized the critical role of Electric Buses (EBs) in mitigating urban pollution, reducing greenhouse gas emissions, and improving public transit comfort [1], [2]. However, the electrification of bus fleets introduces significant challenges, including increased strain on local power infrastructures and rising charging costs. To address these issues, two key approaches have gained substantial attention in recent years.


OnePlus 15 Review: A Phone With Two-Day Battery Life

WIRED

It doesn't look or feel quite like a OnePlus phone, but with speed and battery life like this, who cares? Doesn't get too warm while gaming. Software update policy still doesn't match that of Apple, Google, or Samsung. Cameras are still a step below the top dogs. OnePlus has been churning out Android smartphones for over a decade, yet it still feels like the company is fighting an uphill battle to get a foothold in the US.
