摘要： Some embodiments of the present invention provide a system that accurately and reliably updates a full charge capacity of a battery. During operation, the system charges the battery from an initial state to a rest point prior to reaching a fully charged state. The system then interrupts the charging process to allow the battery to relax to a resting voltage. Next, the system measures the resting voltage. The system then resumes the charging process toward the fully charged state. The system subsequently estimates the capacity of the battery based on the measured resting voltage and one or more other parameters.

摘要： A performance deterioration detecting apparatus configured to detect a performance deterioration start state of an energy storage device. The performance deterioration start state is an initial state of deterioration in performance of the energy storage device. The apparatus includes a performance deterioration determiner configured to determine that the energy storage device is in the performance deterioration start state based on a displacement of peak position in a capacity-voltage property of the energy storage device with time. The capacity-voltage property indicates a relation between a capacity variation amount (dQ/dV) and a voltage (V).

摘要： Methods and systems are disclosed herein for accurately calculating battery consumption in a wireless field device. The total current consumed by a radio board associated with a wireless field device can be determined based on the sum of the current consumed as a result of particular events occurring at the radio board. The current consumed by a sensor board of the wireless field device can then be averated with respect to particular type of sensor. The current consumed by the radio board and the current consumed by the sensor board in the wireless field device can be combined to calculate a predictive value indicative of a remaining life of a battery associated with the wireless field device.
