20100052927 | SYSTEM AND METHOD FOR TESTING CHARGING CURRENT OF A MOBILE ELECTRONIC DEVICE - A system and method of testing charging current of a mobile electronic device sets a charging voltage value and a battery voltage value, and sends a control command to a power supply device to generate the charging voltage and the battery voltage. The system and method further receives a charging current value from a current test device under the charging voltage and the battery voltage. Furthermore, the system and method determine if the charging current value falls in an allowable current range and displays test result on a display device. | 03-04-2010 |
20100315249 | Method and Apparatus for Displaying Battery Remaining Time - A method for displaying battery remaining time is disclosed. Initially, battery voltage, battery current and remaining battery capacity are initially detected. Then, a first battery remaining time at intervals of a first cycle period is determined based on the battery voltage, the battery current, and the remaining battery capacity. The first battery remaining time is updated and displayed on a display unit accordingly. In response to a power consumption change event occurs, a second battery remaining time at intervals of a second cycle period shorter than the first cycle period is determined based on the battery voltage, the battery current, and the remaining battery capacity. The second battery remaining time is then updated and displayed on the display unit accordingly. | 12-16-2010 |
20130049973 | DEVICE AND METHOD FOR CONTROLLING RECHARGEABLE BATTERY - The calculation unit converts into a battery age each parameter calculated for a different factor of degradation of a battery. If at least one of the battery ages has reached an upper limit age, the determination unit determines that it is necessary to conduct a battery diagnosis. Once it has been determined that it is necessary to conduct the battery diagnosis, the display control unit causes a display device to display a diagnosis request message. After displaying the diagnosis request message has started if there is no result of the battery diagnosis received the electric power limiter unit limits electric power charged to and discharged from the battery. After the electric power charged to/discharged from the battery is limited if there is no result of the battery diagnosis received the start-up prohibition unit prohibits starting a system driving the vehicle. | 02-28-2013 |
20160055736 | ADVANCED BATTERY EARLY WARNING AND MONITORING SYSTEM - Systems, apparatuses and methods for detecting internal cell faults using online and real-time sensing techniques, and providing an accurate and reliable early warning for the incoming failure of battery cells hours or days prior to failure. A system is configured to perform real-time and direct measurement of battery cell parameters of temperature, voltage, and AC impedance through online sensing. These parameters may be simultaneously processed using advanced probabilistic and/or fuzzy logic-based algorithms to provide an early warning for the incoming failure of battery cells in a battery pack. This technology may safeguard the LIB battery packs while allowing them to operate at or near 100% capacity in both transportation and stationary applications. | 02-25-2016 |
