摘要： A testing device and method of a quantum battery by a semiconductor probe capable of evaluating electric characteristics of a charge layer in the middle of a production process of the quantum battery without damaging the charge layer. On semiconductor probe constituted by stacking electrode and metal oxide semiconductor on support body, and probe charge layer is formed of the same material as that of quantum battery and irradiated with ultraviolet rays. Forming probe charge layer of same material as that of quantum battery on semiconductor probe enables evaluation without damaging charge layer of the quantum battery. Testing device and method are provided which measure the charge/discharge characteristics of a charge layer in the middle of producing the quantum battery by a voltmeter and a constant current source or a discharge resistor by using the semiconductor probe including the probe charge layer.

摘要： In accordance with one aspect of the present technique, a method is disclosed. The method includes identifying a first change in an excitation direction of a group of cells and determining a first set of characteristics of the group of cells corresponding to the first change. The method also includes identifying a second change in the excitation direction of the group of cells and determining a second set of characteristics of the group of cells corresponding to the second change. The second change in the excitation direction is opposite to the first change in the excitation direction. The method further includes determining a number of functional cells from the group of cells based on the first and the second set of characteristics.

摘要： A method and system are provided for estimating state of charge of a cell having a positive electrode, for example of a lithium phosphate type, the charge profile of which includes a range of state of charge between about 30 and about 90% in which variation of voltage is 10 times less rapid than for a state of charge higher than 90%. Determination of state of charge for a state of charge greater than 90% is based on either the use of a calibration relationship between cell voltage and state of charge when a current is passing through the cell that is less than a predetermined threshold value and its voltage has stabilized, or on the use of coulometry the result of which is corrected taking into account the accuracy of the current sensor.
