摘要： An energy storage unit for a motor vehicle battery is provided, having an energy store, particularly configured as a battery cell module, for storing and delivering electric power. A measuring device measures electrical properties of the energy store. An evaluation unit, connected to the measuring device, ascertains the operational status of the energy store from the measurement results of the measuring device. An indicator unit is connected to the evaluation unit for depicting the operational status of the energy store. By ascertaining and depicting the operational status and not just the state of charge of the energy store, it is possible to dispense with separate complex measurements when fitting the energy store, so that an energy storage unit can be checked quickly and efficiently when fitted into a motor vehicle.

摘要： An electronic device and a detection method of power capacity are provided. The electronic device includes a battery and a power management unit coupled to the battery. The power management unit reads an output voltage of the battery, and determines whether a variation of the output voltage of the battery within a time interval is greater than a threshold. When the power management unit determines that the variation of the output voltage of the battery within the time interval is greater than the threshold, the power management unit calculates a remaining power capacity of the battery according to the output voltage and the variation of the output voltage within the time interval.

摘要： Proposed is a method for efficiently indicating the replacement timing of each battery module which is a constituent element of a battery system on the basis of operational results information of the battery system without lowering the operating ratio of the battery system. First, capacity-voltage profile data of the battery module according to manufacturing state and degradation state, capacity-voltage profile data at the time of shipping of the battery module, and most recent capacity-voltage profile data of the battery module are collated to estimate the degradation degree of the battery module of the battery system. Then, based on past charge/discharge results data of the battery module, a future use pattern is estimated. Thereafter, remaining operating life is computed based on the degradation degree, the use pattern of the battery module, and characteristics degradation data. Finally, based on the remaining operating computed for the life battery module, the replacement timing of the individual battery module is indicated.

摘要： One terminal of a switch 53 is connected to a resistor 51 having its other terminal connected to a rechargeable battery, and the other terminals connected through a resistor 54 to a capacitor 55. Another capacitor 52 is connected to the node between the switch 53 and the resistor 51. Initially, while the switch 53 is in the OFF state, the rechargeable battery charges the capacitor 52 towards the battery voltage through the resistor 51. When the switch 53 is turned ON, capacitor 55 and capacitor 52 become connected in parallel and the voltage across capacitor 55 rises within a short time period. When the switch 53 again turns OFF, voltage indication continues in compliance with the voltage across the capacitor 55 even as that voltage decays according to the time constant of the parallel circuit formed by the capacitor 55 and a series-connection of resistors 71, 72.
