If you’re testing a power supply or battery pack, an electronic load is a nice tool to have. By watching the voltage as you crank up the resistance, you can verify the unit’s real-world capabilities quickly and easily. But [Xavier Bourlot] wanted a bit more information than is general...
Large-scale energy storage is certain to play a significant, enabling role in the evolution of the emerging electrical grid. Battery-based storage, while not a dominant form of storage today, has opportunity to expand its utility through safe, reliable, and cost-effective technologies. Here, seco...
In a first embodiment, the contact plate includes at least one primary conductive layer, wherein the contact plate is configured to exchange current with at least one group of battery cells in the battery module, and wherein a thickness of the at least one primary conductive layer scales with...
material is comprised of 60% cobalt by mass12. Note that from this point forward, we use “positive” and “negative” electrodes in place of the common terminology “cathode” and “anode” to avoid ambiguity since the latter terms are only valid for the discharge of a rechargeable battery...
an Arduino Nano into a Swiss Army knife of portable hacking. It can function as an analog multimeter to measure resistance, voltage drop, and continuity. It can also produce PWM signals, read from sensors, do basic calculator functions, and display the health of its rechargeable battery pack....

energy storage systems provide an optimal solution for utilities, independent power producers and microgrids seeking a reliable, safe and durable solution for four- to twelve-hour power storage that doesn’t degrade over time. That is the capability that ESS iron flow battery...
For example, combining a high-energy (HE) pack and a high-power (HP) pack enables to cover more applications for an interoperable service portfolio. Such a strategy increases the flexibility in sizing and thus the possibility of the economy of scales, which may help reduce the TCO. There ...
Wind droughts, or prolonged periods of low wind speeds, pose challenges for electricity systems largely reliant on wind generation. Using weather reanalysis data, we analyzed the global distribution of and trends in wind droughts using an energy deficit
