Patent number: 9718375Abstract: A 12 volt automotive battery system includes a first battery directly coupled to an electrical system, in which the first battery includes a first battery chemistry, and a second battery coupled in parallel with the first battery and directly coupled to the electrical system, in which the second battery includes a second battery chemistry with a higher coulombic efficiency than the first battery chemistry. The first battery and the second battery are non-voltage matched such that a voltage range of the second battery is higher than a voltage range of the first battery. The first battery steers power generated during regenerative braking to the second battery using internal resistance of the first battery to enable the second battery to capture a majority of the power generated during regenerative braking, and the second battery provides power to the electrical system due to the higher voltage range of the second battery when the second battery has a positive state of charge.Type: GrantFiled: January 23, 2014Date of Patent: August 1, 2017Assignee: Johnson Controls Technology CompanyInventors: Daniel B.

Patent number: 9625533Abstract: The present disclosure describes a method that includes predicting terminal voltage of a battery module in a vehicle using a battery control module. Predicting the terminal voltage includes determining a gassing current of the battery module using a gassing current model, in which the gassing current quantifies terminal current that is not used to charge the battery module, and calculating the predicted terminal voltage based at least in part on a measurement model and the determined gassing current. The method also includes measuring terminal voltage of the battery module using a sensor communicatively coupled to the battery control module, and determining a corrected state of the battery module using the battery control module by minimizing a difference between the predicted terminal voltage and the measured terminal voltage. In other words, the corrected state of the battery (e.g., corrected state of charge) may be more accurately determined using the measurement model and the gassing current model.Type: GrantFiled: April 15, 2014Date of Patent: April 18, 2017Assignee: Johnson Controls Technology CompanyInventors: Daniel B.

Patent number: 9469212Abstract: A system for providing power to a power network includes an energy storage device connected to the power network, a sensor connected with the energy storage device for measuring a state of the energy storage device during a rest period, which corresponds to a time span during which a current through the energy storage device is reduced to a level that enables an estimation of a state of the energy storage device. The system further includes a controller connected to the sensor for measuring a state of the energy storage device. The controller selectively establishes rest periods for the energy storage device. The rest periods are established by optimizing between minimization of disruption to normal operation and a need to update a measurement of the state of the energy storage device.Type: GrantFiled: June 26, 2015Date of Patent: October 18, 2016Assignee: Johnson Controls Technology CompanyInventors: Brian C.
