Specification of lithium-ion battery testers must take into account that the actual power consumed varies with time, and that there will be losses. This article takes a deep dive into the amount of charging power needed for a single small cell.
The quest continues to have your shirt provide harvestable energy. Two novel methodologies attempt to find the solution, one implementing conductive polymers and the other using coated silk.
Thermal management is critical for rugged-systems design, where SWaP-C (size, weight, power, and cost) constraints require innovative cooling strategies.
