All You Need to Know About Various Charge-Discharge Curves of Lithium Batteries in One Article
Aug
This article systematically dissects various charge/discharge curves of lithium-ion batteries. It explains the curve profiles corresponding to mainstream charging/discharging modes, including constant current (CC), constant voltage (CV), CC–CV, constant power, and constant resistance. It interprets the electrochemical mechanisms behind voltage plateaus, inflection points, and slope variations—such as polarization and phase transitions during lithium intercalation/deintercalation—and establishes…

In lithium battery pack manufacturing, cell consistency is one of the most important factors determining long-term safety, reliability, and service life. Most battery manufacturers use three core parameters to match cells before pack assembly: Open-circuit voltage Internal resistance Capacity or energy These measurements are essential. They help ensure that cells assembled into the same battery…

Why DJI Intelligent Batteries Become “Locked”: Understanding BMS Protection, Deep Discharge, and Proper Storage
Jul
Many drone pilots have experienced the same frustrating situation: A battery is left unused for several weeks or months. When it is taken out again, it will not charge. Pressing the power button produces no indicator lights. The charger does not recognize it, and the drone cannot detect it. In the drone community, this is…

Choosing the Right Battery for AGVs, RGVs, and AMRs: Why Total Cost Matters More Than Battery Price
Jul
Have you ever seen a fulfillment center during a major e-commerce promotion? Hundreds of AGVs and AMRs move between shelves, racks, conveyors, and picking stations. Every second counts. If one vehicle loses power and stops in a narrow aisle, the result is not simply one idle machine. It may block an entire logistics route. Production…

For more than a decade, when people talk about drones, one image usually comes to mind: A quadcopter with four propellers. From DJI Phantom and Mavic series dominating the consumer drone market, to agricultural drones carrying 20 kg of pesticides, to delivery drones serving remote islands and mountainous regions — rotor drones have become the…
When Drones No Longer Depend on Ground Networks For decades, one fundamental limitation has constrained the evolution of drones: A drone can fly farther than it can communicate. Whether it is disaster rescue, remote inspection, military reconnaissance, or industrial surveying, unmanned aerial systems have always depended on a communication chain: Drone → Ground Station →…
On July 20, 2026, at MetLife Stadium in New Jersey, the curtain finally fell on the FIFA World Cup era that defined an entire generation. The final between Spain and Argentina was more than just a football match. It was a farewell. A farewell to legends. A farewell to memories. A farewell to the youth…

Solid-State Batteries: Why the Winning Technology May Not Be the One With the Highest Energy Density
Jul
For years, the solid-state battery race has been defined by one question: Who can achieve the highest energy density first? However, the next major breakthrough in battery commercialization may not come from the technology with the most impressive laboratory data. It may come from the technology that can successfully move from prototype validation to stable…

PCM vs. BMS: They Are NOT the Same—Understanding the Difference Could Prevent Battery Failure
Jul
If you’re new to lithium batteries, building battery packs, upgrading power systems, or sourcing battery solutions, you’ve probably encountered two terms repeatedly: PCM (Protection Circuit Module) and BMS (Battery Management System). Many people use these terms interchangeably. They shouldn’t. Confusing a PCM with a BMS isn’t just a technical mistake—it can lead to reduced battery…
