Certain embodiments are described that provide a method and computer readable media for testing battery cells. A unique identifier (e.g., barcode) is affixed to a battery cell which allows it to be tracked across separate tests as a cell, in a module, string, pack, etc. Using a GUI, the unique identifier is recorded in a database along with at least a battery cell manufacturer and a battery cell model. A designation of the particular tester channel or module or string location is entered into the database in association with the unique identifier. Test results of the first test are electronically transferred from the first tester to the database along with the corresponding channel designations.

Battery cell full life tracking system

Serial communication verification and safety control is disclosed. A multi-part system such as a battery management system can include distributed or subsidiary components for determining status of various parts of the system with the components in serial or point-to-point communication with a collective main controller. A safety controller can be implemented to passively be coupled to the serial or point-to-point communication between the main controller and the subsidiary units. The safety controller can monitor and verify the communication between the main controller and the subsidiary units and send a safety command or verification indicator in another line of communication separate from the communication bus between the main controller and the subsidiary units.

Serial communication safety controller

A battery management system (BMS) connected to a battery is disclosed. The battery management system includes a battery status component configured to detect one or more parameters of the battery; a timer component configured to compute an amount of time needed to recharge the battery based on one or more of the parameters of the battery; and a scheme initiation component configured to determine an optimal time to begin charging based on the amount of time needed to recharge the battery.

Systems and methods for intelligently charging battery cells

A closed loop energy storage system configured with a hydrogen tank, an oxygen tank, a fuel cell stack and an electrolyzer. A heat exchanger freeze-dries the hydrogen and oxygen prior to their storage in their respective tanks. The heat exchanger also uses excess fuel cell heat to preheat streams of hydrogen and oxygen coming from the tanks. Phase separators serve both to separate water from hydrogen and oxygen, and to store the water. A thermal management system encloses all the system components except the tanks. An airfoil-shaped shell covers the system, and the larger of the two tanks extends substantially across the shell at its point of greatest camber thickness. The tanks are composed of polymer liners integral with composite shells.

Energy storage system

The method of producing O from water, that includes subjecting water to electrolysis, to produce H and O , returning H to a water storage zone, drying the produced O , using air as a drying agent, flowing a stream of that drying agent air to the cathode side of fuel cell, flowing a stream of produced hydrogen to the anode side of the fuel cell, for reaction with O in the agent air to produce water electrical energy and heat, and using electrical energy produced by fuel cell in the electrolysis.
