Abstract: A sensor system for mitigating a flame condition in a battery subject to an overcharge condition and being charged using a charging current is provided. A temperature sensor is configured to detect a temperature of at least one component of the battery, and a gas sensor is configured to detect an inflammable gas or vapor. A sensor control is configured to, when the temperature of the at least one component of the battery exceeds a pre-determined temperature threshold and when the gas sensor detects an inflammable gas or vapor, halt the charging current.

Abstract: An flight-safe indicator for a battery displays the flight-safety state of a battery to be transported by an aircraft. The indicator can be easily recognized by ground personnel anywhere regardless of the language they speak or read. The indicator comprises an icon indicating that the battery is safe for flight and would be easily recognized by personnel at an airport. The icon would be placed on the battery or on the battery packaging prior to loading on the aircraft. When the magnitude of power stored on the battery exceeds a safety threshold, the icon changes to an indication that the battery is not safe for transporting by aircraft and the operator may discharge the battery using a load until it reaches a safe level.

Abstract: A system and method for ensuring the readiness of a mission critical battery in a device, the system includes a rechargeable battery as the mission critical battery disposed within the device slaved to a primary charging battery through a charge controller both of which are disposed outside of the device. The charge controller is programmed to ensure that the primary charging battery delivers a charge to the mission critical battery to maintain the mission critical battery at a charge level for maximized long term storage. The storage charge level may be 50% of the full charge level of the mission critical battery. The charge controller will receive a mission signal when the device is to be mission ready. The charge controller will then transfer the appropriate amount of stored energy from the primary charging battery to the mission critical battery to achieve full charge.

Abstract: A system for power balance monitoring in an energy storage battery comprising a plurality of energy modules connected in a series-parallel configuration. The energy storage module comprises a plurality of cells. Each module is a three-terminal module. The three terminals comprise a positive output terminal and a negative output terminal for connecting the modules in a series string to a load and an energy sharing terminal for sharing energy between modules is other battery strings. A module power management sub-system comprising a current monitoring circuit is connected to each of the energy sharing terminals. Each module power management sub-system is in communication with a battery power management sub-system so that a weak module can be detected based on module current output. Advantageously, the module power management sub-system is not connected across the main power pathway of the module and so does not appreciably increase module impedance.

Abstract: A system and method for stopping a wind turbine in a battery charging circuit includes a step to terminate battery charging by opening a first switch between an electrical generator coupled to the wind turbine and the battery. A second switch between the electrical generator output terminals is then closed in order to short the generator, create a drag on the wind turbine and ultimately stop its rotation. The signal to open the first switch is generated by a battery charge monitor which when sensing a full charge on the battery will open the first switch and close the second switch. In another embodiment, there is a wind turbine auto stop signal generator connected to the battery monitor to close the second switch upon receipt of a signal indicating full battery charge from the battery monitor. In yet another embodiment there is a remotely located control computer networked to the battery monitor and the wind turbine auto stop signal generator.

Abstract: Described is an energy share pack comprising a housing, at least one energy storage component within the housing, at least one energy conversion component within the housing, and a connection point for connecting to more than one of energy users, energy sources and other energy share packs simultaneously for sharing energy. The energy share pack may have an energy generation component for generating harvestable energy, and two or more ports of any combination of the following types: bidirectional power port, bidirectional USB port, unidirectional output power port, and unidirectional input power port. The share pack ports may operate simultaneously at different voltage levels, and at least one port may be bi-directional. Furthermore, the share packs may have an integrated display for providing information on the energy share pack in which the display is integrated and information about other energy share packs connected thereto.

Abstract: A system and method is provided that allows the cells making up a battery pack to be kept at equal energy storage levels through the use of active re-distribution of the energy in each cell through a bi-directional transformer coupling means that will allow balancing to occur during charging, discharging, bulk charging, parallel charging or idle states.

Abstract: An n-phase transformer includes a core structure having a polygonal top plate and a polygonal bottom plate and n winding posts disposed symmetrically between the top and bottom plate. The primary and secondary winding loops are integrated into printed circuit boards which are then stacked over the posts in laminate fashion between the top and bottom plate.
