In certain embodiments, an energy generation system includes at least one pair of asymmetrically porous electrodes positioned within a chamber in selective fluidic communication with a freshwater source (e.g., a river) and a saltwater source (e.g., an ocean). Asymmetry between a first average percent volume per unit pore-width of a first electrode and a second average percent volume per unit pore-width of a second electrode creates differing interfacial potentials between the first electrode and the second electrode when such electrodes are immersed in freshwater and saltwater. By cyclically immersing the electrodes in freshwater and saltwater, energy is harvested from Gibbs free energy from mixing saltwater and freshwater. Such a system does not require a membrane or an external charge source. Methods of generating energy using asymmetrically porous electrodes are also provided.

    Abstract: A rechargeable energy storage system includes a battery pack and a battery controller. The battery pack has a voltage current temperature module and multiple battery modules. Respective battery modules have multiple battery cells and are operable to store a module identifier that encodes at least one parameter of the battery cells, receive a configuration request from the voltage current temperature module, and transfer the module identifier to the voltage current temperature module in response to the configuration request. The battery controller is in communication with the voltage current temperature module and is operable to send a status request to the voltage current temperature module, receive the plurality of module identifiers from the voltage current temperature module in response to the status request, and compare the module identifiers to determine either a match or at least one mismatch among the module identifiers of the battery modules.

  • Patent number: 11567134
    Abstract: A system and method for monitoring characteristics of an electric energy device includes generating an external short from the electric energy device. The external short occurs at a known distance from a sensor and has at least one known external resistance. The received signal representing change in electromagnetic field due to the applied external short may be analyzed to determine a signal parameter that is then analyzed in comparison to a lookup table, based on the known conditions including distance, temperature and the external resistance. The output of this analyses in comparison with expected values may be utilized to identify a characteristic of the energy device.
