  • Patent number: 10775444
    Abstract: A secondary battery system includes a control device that estimates a reaction resistance based on the difference between a first impedance and a second impedance. Each of the first and second impedance is calculated based on first, second, and third change amount when the current value of the secondary battery is varied with corresponding period. The first change amount is a change amount of a detection value of a voltage sensor in a period in which the phase of the current value is inverted from an initial phase to an opposite phase, the second change amount is a change amount of the detection value of the voltage sensor in a period in which the phase of the current value is returned from the opposite phase to the initial phase, and the third change amount is a difference of the current value between the initial phase and the opposite phase.

  • Patent number: 10753985
    Abstract: To determine in a simple and unequivocal manner whether measurement contacts at which a voltage is to be measured have been properly contacted in a measurement system, in the measurement system, after a discharge switch connecting a charging circuit to a voltage measurement device is closed, the charging circuit is discharged via an internal resistance of the voltage measurement device. When the discharge switch is closed, after a measurement switch connecting the voltage measurement device to the measurement contacts is closed, it is established whether the electrical system is contacted with the measurement system by analyzing the voltage curve at the voltage measurement device after closure of the measurement switch. Advantageously, after the discharge switch is closed, the charging circuit is discharged via a discharge resistor connected in series or in parallel with the voltage measurement device and via the internal resistance.

In one embodiment, a relay may include an electrical parameters module that receives a representation of a voltage and a current at a terminal of rotating machinery in an electric power system. A torque calculation module may continuously determine a calculated torque value for the rotating machinery using the representation of the voltage and the current at the terminal of the rotating machinery and compare each calculated torque value to a threshold. An action module may generate an alarm when the calculated torque value exceeds the threshold. A log module may generate a log comprising a peak of the calculated torque value and a time at which the peak torque value occurs.
