An estimation device configured to estimate a charge rate of a battery includes a voltage sensor configured to detect a voltage of the battery, a temperature sensor configured to detect a temperature of the battery, and a processing circuit. The processing circuit is connected to the voltage sensor and the temperature sensor and is configured to execute, while a vehicle is parked, an estimation process of estimating the charge rate of the battery based on a detection voltage and a detection temperature. The detection voltage is detected by the voltage sensor. The detection temperature is detected by the temperature sensor.

The present invention relates to a powerline de-icing device primarily comprised of a body, further comprised of at least one solar panel, at least one battery, at least one heating element, and at least one heat-able wire. In the preferred embodiment, the device is comprised of a solar panel that supplies power to the battery, wherein the battery supplies power to the heating element which provides an electrical charge to the wire and in turn heats the wire. The wire can then be wrapped and secured around a power line to prevent ice and snow from forming on the power line. Furthermore, the device may be comprised of a temperature sensor that automatically activates the heating element when the ambient temperature around the device is below a threshold temperature (e.g., 32 degrees Fahrenheit).

A sensor board receives a voltage difference between a battery pack not connected to the power bus and the power bus; determines whether the voltage difference indicates that a battery pack voltage is within a threshold voltage difference from a power bus voltage; in response to determining the voltage difference indicates that the battery pack voltage is not within the threshold voltage difference from the power bus voltage, provides a drain indication to drain off the battery pack using a power draw mechanism until the voltage of the battery pack is within a threshold voltage difference of the power bus; and provides a connect indication to connect the disconnected battery pack to the power bus.

The ParaDice Process System is the interconnection of a renewable power source to power an ocean water electrolysis apparatus comprising a water container, an electrolysis cell, optionally a precious metal harvesting probe, a filtration system, and a settlement pond wherein the hydrogen generated as a result of electrolysis is supplied to either a hydrogen combustion engine or hydrogen turbine to power an electricity generator thereby creating a renewable zero carbon emission electric power generation system. The hydrogen gas is collected by a chlorine scrubber and transferred to either a hydrogen combustion engine or a hydrogen turbine. Where a hydrogen turbine is embodied the waste heat created therein is used to generate electricity and increase the performance of the filtration system and settlement pond.

A battery system includes a power bus and a set of battery packs. A battery pack is one or more batteries, a sensor board, and a power board. The power bus is used to electrically connect the set of battery packs. The sensor board receives a voltage difference between a battery pack not connected to the power bus and the power bus; determines whether the voltage difference indicates that a battery pack voltage is too high compared to a power bus voltage; in response to determining the voltage difference indicates that the battery pack voltage is too high compared to the power bus voltage, provides a drain indication to drain off the battery pack using a power draw mechanism until the voltage of the battery pack is within a threshold voltage difference of the power bus; and provides a connect indication to connect the disconnected battery pack to the power bus.

An energy storage system (ESS) including a battery management system (BMS) arranged to monitor and control operations associated with charging and discharging electrical current from a storage element where the BMS is positioned within a cavity of a housing. A site controller coordinates operations of the ESS with a component of a power distribution system where the site controller is positioned within the housing's cavity. The storage element may include one or more battery cells. The ESS may include a frame defining the housing's cavity and including first and second side panels and a front access panel. The access panel may include at least one hinge in proximity to the first side panel where the hinge is arranged to prevent a portion of the hinge from extending beyond an edge of the first side panel as the access panel rotates from a closed position to an open position.
