Apparatuses, systems, and methods for collecting, transporting, and purifying water using human energy from transport. A barrel shaped water impermeable container made of material comprising an ultraviolet (UV) light stabilized polymer that can be pushed or rolled. The container has one or more ports with removable filters to remove pre-sediment prior to transport and post-sediment after transport. A translucent water impermeable casing comprising an electrical box having at least two removable and replaceable UV lights, connected to copper coils with rotating magnets inside the coil generate power to light the ultraviolet lights and purify water in the container. Three or more removable proportionally spaced carbon fin cartridges rotate about a container closed end axis when the container is pushed or pulled to provide additional purification. Carbon fin cartridges can have a polylactic acid shell wrapped in liquid permeable mesh shell and evenly spaced holes packed with carbon.

Provided is a battery state estimation device configured to: calculate a first state of charge and a first open circuit voltage corresponding to the first state of charge by using a detection current output from a current detection unit and state-of-charge estimation parameters; calculate a second open circuit voltage and a second state of charge corresponding to the second open circuit voltage by using a detection voltage output from a voltage detection unit and equivalent circuit parameters; recursively estimate and update the state-of-charge estimation parameters by using a state-of-charge error, which is a value obtained by subtracting the first state of charge from the second state of charge; and recursively estimate and update the equivalent circuit parameters by using an open circuit voltage error, which is a value obtained by subtracting the first open circuit voltage from the second open circuit voltage.

A battery includes a housing, and within the housing, an anode having an alkali metal as the active material, a cathode having a mass (m) of a cathode active material, for example, iron disulfide as the active material, a separator between the anode and the cathode, and an increased electrolyte volume (v).
