Current measuring system for power source charging and discharging
The patent US11994540B2 describes a current measuring system designed to monitor and manage the charging and discharging of a power source. The system includes a current measurer that generates an output signal when it detects current in a conductor connected to a power source. This measurer is linked to two circuits: the first circuit indicates when the power source is charging, while the second indicates when it is discharging. A controller processes the output signals from both circuits to determine which signal exceeds a predefined threshold, subsequently linearizing this signal for further analysis. The system is capable of harvesting energy to power itself when measuring AC current and can interface with both remote and local systems for command reception.
Further technical details reveal that the first circuit employs an inverting operational amplifier connected to a power supply, while the second circuit utilizes a biasing circuit and a non-inverting operational amplifier. The system also incorporates a voltage regulator to manage reference voltages and includes a coulomb counter to measure the capacity of the power source. The controller is designed to process the output signals into a digital format and can operate based on signals from remote systems or at predetermined intervals. Additionally, the system can enter a sleep mode after data transmission and is equipped to send error signals if any output or supply rail voltages fall outside specified thresholds. Overall, the patent outlines a comprehensive approach to current measurement and management in power systems.
