Lithium-iron battery maintenance guide

Setec Powerr

We recommend that all lithium batteries and cells not-in-use go through at minimum one full maintenance cycle (charge to 100% SoC (state of charge), discharge to 100% DoD (depth of discharge), charge to 50% SoC) once every 6-12 months to maintain the battery’s capacity.

DOE awarding $35M to 11 projects for hydrokinetic turbine development; ARPA-E SHARKS

Green Car Congress

Projects are encouraged to apply concurrent (as opposed to sequential) design methodologies: control co-design, co-design, and designing for operation and maintenance. HydroMINE is a disruptive and elegantly simple system with an internal propeller driven by pressure from a stationary hydrofoil structure to a separate, internal flow stream.
