| 20120022817 | Measuring and Monitoring a Power Source - The disclosed battery monitoring systems and methods may minimize measurement errors due to noise and/or other disruptions. The sensor may generate a pulse width modulated signal that when applied to the battery forms an AC test signal having a defined waveform, frequency, amplitude, and/or duration. The sensor may measure the battery's response to the test signal. The resultant response signal may be measured to determine the health of the battery, including its internal admittance. The sensor may determine an optimum frequency to test the battery by scanning a frequency range and measuring the amount of noise present. | 01-26-2012 |
| 20110288798 | Method and Apparatus For Measuring and Monitoring a Power Source - A system and method for monitoring a power source using a site controller and first and second sensors are described herein. The system may include a first power source in communication with a second power source. The system may include a first sensor in communication with the first power source and the first sensor may calculate an exponential discharge characteristic of the first power source. The system may include a second sensor in communication with the second power source and the second sensor may calculate an exponential discharge characteristic of the second power source. The system may include a controller in communication with the first sensor via the second sensor wherein the controller may determine the characteristics of the first power source as a function of the exponential discharge characteristic of the first power source. | 11-24-2011 |
| 20110068746 | METHOD AND APPARATUS FOR INTELLIGENT BATTERY CHARGE EQUALIZATION AND MONITORING - An intelligent battery charge equalization and monitoring system may assist in the management of battery string health by detecting individual batteries within a string that may need servicing. The system may detect a battery within a string that is charged to a higher voltage than other batteries within the string and discharge the overcharged battery until the battery's charge is equalized with the other batteries in the string. The system may use metrics related to how often individual batteries within a string of batteries must be equalized and utilize these metrics to perform maintenance actions. | 03-24-2011 |
