A power system adapted for supplying power in a high temperature environment is disclosed. The power system includes a rechargeable energy storage that is operable in a temperature range of between about seventy degrees Celsius and about two hundred and fifty degrees Celsius coupled to a circuit for at least one of supplying power from the energy storage and charging the energy storage; wherein the energy storage is configured to store between about one one hundredth (0.01) of a joule and about one hundred megajoules of energy, and to provide peak power of between about one one hundredth (0.01) of a watt and about one hundred megawatts, for at least two charge-discharge cycles. Methods of use and fabrication are provided. Embodiments of additional features of the power supply are included.

A method performed by a control unit for controlling flooding of at least part of an energy storage space. The energy storage space comprises at least one Energy Storage System, ESS. The control unit detects that a critical condition associated with the at least one ESS is present. When the critical condition has been detected, the control unit initiates flooding of at least part of the energy storage space with a fluid from a reservoir. The control unit controls the flooding of the energy storage space such that the at least one ESS is submersed to a submersion level where the critical condition is no longer present.

An atmospheric water generation system absorbs water from an atmospheric air stream into a desiccant flowing along a flow path of a closed desiccant circulation loop. To ensure that the desiccant remains within the closed desiccant circulation loop, the atmospheric water generation system encompasses a membrane-based water extraction device that the desiccant flows through. The desiccant flows through the membrane-based water extraction device on a first side of a membrane, and the membrane separates the desiccant from a water-collection flow. Water absorbed into the desiccant passes from the desiccant, through the porous membrane, and into the water-collection flow, at least in part due to differences in temperature and/or pressure characteristics of the water flow and the desiccant flow. Water collected within the water-collection flow is directed to a storage tank for usage.

A system for powering 100% of an oil and gas workover rig's operations with a battery energy storage system (“BESS”). The system consists of three major interconnected components: a BESS, a power conversion system (“PCS”), and a workover rig. The power system is specifically designed for a retrofitted electro-mechanical workover rig (with either an alternating current or direct current electric drive) which is compatible with the BESS. Unlike other emerging industrial applications, a battery cannot be mounted on the workover rig due to logistical and size constraints, thus requiring a novel modular and mobile system design.

According to one embodiment, provided is a secondary battery including a negative electrode containing a titanium-containing oxide, a positive electrode, a separator between the negative electrode and the positive electrode, a first aqueous electrolyte, a second aqueous electrolyte, and a third aqueous electrolyte. The first aqueous electrolyte is held in the negative electrode and contains 0.001% by mass to 0.5% by mass of zinc ions. The second aqueous electrolyte is held in the separator and contains 1% by mass to 5% by mass of a first compound that includes a hydrophobic portion and a hydrophilic portion. The third aqueous electrolyte is held in the positive electrode.

A battery pack includes a main body, and a handle rotatably connected to the main body. The handle is integrally formed by a steel wire. A related garden tool includes a working head, a power driving device for driving the working head to work, and the battery pack.

Power generation devices and methods for use with toilets is disclosed. A number of power generation devices are provided that can be used in combination to power various features in a toilet which will be particularly useful for portable toilets that are off the grid. The power generation devices and methods include, for example, using a cell battery inside a toilet water source, a wind turbine, solar panels, and piezoelectricity. The features include, for example, lighting up the toilet with light-emitting diodes (LEDs) to make it easier for users to find the toilet, an audio/video setup for entertainment, and a toilet status light indicator to let the next user know when the toilet paper is out.

An electronic module adapted to an electronic apparatus is provided. The electronic apparatus includes a casing and an electronic assembly, and the electronic assembly is disposed on the casing. The electronic module includes at least one electronic component, a carrier, a rotation component, a connection component, and an elastic assembly. The carrier carries the electronic component, and the carrier is arranged on the casing. The rotation component is pivotally connected to the carrier. The connection component is connected pivotally to the rotation component. The elastic assembly is disposed on the connection component and a hook portion is disposed thereon. The hook portion is adapted to be hooked to the casing, such that the electronic component is plugged to the electronic assembly by the elastic assembly.

A communication device is provided with: a first communication part that is connected to an energy storage device or a power supply related apparatus and communicates with the energy storage device or the power supply related apparatus; an acquisition part that acquires information including a state of the energy storage device or the power supply related apparatus on the basis of a set timing; a change acceptance part that accepts a change in the timing and changes the timing; and a transmission part that transmits, at a timing after the change, the information acquired by the acquisition part to a first apparatus by using a second communication part communicatively connected to the first apparatus.
