Abstract: Series and series/parallel connection of Li-ion modules is required to build Li-ion energy storage systems (ESS) up to the desired voltage level and energy capacity. Embedding several ...

These light up paper circuit cards were much easier to make than I expected and only need a few inexpensive materials.

This pytest plugin takes a set of tests that would be normally be run serially and execute them in parallel. The main goal of pytest-run-parallel is to discover thread-safety issues that could exist ...

A blast from the Elektor archives: this 1998 battery tester uses a simple LED display to reveal a battery’s true condition under load — even below 1 V.

Abstract: Series-parallel hybrid systems have become an important development direction for hybrid vehicles. To improve the energy efficiency of series-parallel hybrid systems, in this study, first, ...
