Abstract: A battery management system includes thermal batteries, sensors, a clock, a processor, and memory storing a data structure, and is configured to receive energy parameters and time data, calculate a rate of energy usage of the thermal batteries based on the received data, and execute battery commands to activate or disable selected thermal batteries. Energy usage data can be stored as individual data points over time, and battery commands can be received from an external computer. The system determines when to activate a second battery based on a predetermined threshold of estimated electrical energy of a first thermal battery. A battery management method includes receiving signals for voltage, current, temperature, and time duration, estimating electrical energy based on these parameters, and activating a second battery when the estimated energy falls below a predetermined threshold.

Abstract: An electrical apparatus includes first and second battery interfaces disposed on a housing for electrically and mechanically connecting first and second battery packs in series. A controller is disposed within the housing and includes an apparatus microprocessor that receives first and second communication signals respectively outputted from respective microprocessors of the first and second battery packs. A first signal communication path communicates the first communication signal from the first battery pack microprocessor to the apparatus microprocessor by shifting a first voltage range of the first communication signal to a second voltage range that is suitable for inputting into the apparatus microprocessor. A second signal communication path communicates a third communication signal from the apparatus microprocessor to the first battery pack microprocessor by shifting the second voltage range of the third communication signal to a first voltage range that is suitable for inputting into the first battery pack microprocessor.

Abstract: A method for conducting an operation including a power tool battery pack. The battery pack can include a housing, a first cell supported by the housing and having a voltage, and a second cell supported by the housing and having a voltage. The battery pack also can be connectable to a power tool and be operable to supply power to operate the power tool. The method can include discharging one of the first cell and the second cell until the voltage of the one of the first cell and the second cell is substantially equal to the voltage of the other of the first cell and the second cell.

Abstract: Provided is a battery module. The battery module includes: a plurality of battery cells each including an electrode terminal; and a bus bar connected to the electrode terminals of the battery cells neighboring each other to electrically connect the battery cells, the bus bar including a first bus bar and a second bus bar that are superposed on each other and include different metals, each of the first and second bus bars making conductive contact with the electrode terminals. Therefore, the thermal and electrical characteristics of the bus bar electrically connecting the neighboring battery cells to each other may be improved while improving weldability between the bus bar and electrode terminals.

Abstract: Systems and methods for monitoring and responding to forces influencing batteries of electronic devices are provided. One or more sensors may be provided at various positions within a battery assembly including one or more battery cells within an enclosure. In some embodiments, a sensor may be provided between a battery cell and a portion of the enclosure. In other embodiments, a sensor may be positioned between two adjacent cells in a stack. Each sensor may detect a force influencing a battery cell of the assembly. In some embodiments, the sensor may be a force sensing material having a conductance configured to vary based on the influencing force. In other embodiments, the sensor may be a contact sensor that detects when the influencing force moves two elements together.

Abstract: Battery assembly techniques and a corresponding system are disclosed. In various embodiments, the battery assembly techniques include compressing battery cells and inserting the battery cells in a can. Battery cells are stacked and then compressed using pneumatic cylinders that exert pressure on a first external layer of the stacked battery cells. A first portion of the stacked battery cells is released from the pneumatic cylinders while a second portion of the battery cells remains compressed. The first portion of the stacked battery cells is inserted in a can. In various embodiments, friction decreasing materials are added to the stacked battery cells to compress the stacked battery cells or ease insertion.
