Patent number: 9748786Abstract: Embodiments of the present invention are directed to a battery stack with a leapfrogging communication network. Each cell stage may include a controller, a transmitter, and a pair of receivers. The cell stage in the battery stack may be coupled to the closest two preceding battery cell stages in the stack. In this manner, each cell stage may be able to determine if a fault is present in an immediately preceding cell stage in the stack by monitoring the first preceding cell stage and the second preceding cell stage. If discharge/charge commands transmitted by the second preceding cell stage are not reaching the battery cell stage at issue, the controller may determine that there is a fault in the first preceding cell stage and discharge/charge the cell stage based on the commands transmitted by the second preceding cell stage.Type: GrantFiled: August 5, 2014Date of Patent: August 29, 2017Assignee: Analog Devices, Inc.Inventors: James C. Camp, Thomas M. MacLeod

Patent number: 9728819Abstract: A non-aqueous electrolyte battery system includes a battery voltage output section for outputting a voltage of a non-aqueous electrolyte secondary battery and a freezing determination section for performing freezing determination to a non-aqueous electrolyte. In the freezing determination, the freezing determination section executes freezing determination current control for supplying a current at a freezing determination current value at a freezing determination time in a direction to charge the non-aqueous electrolyte secondary battery. When a voltage value output from the battery voltage output section exhibits a transition that rises once to a peak value during execution of the freezing determination current control, and then decreases with time, it is determined that the non-aqueous electrolyte is in a frozen state.Type: GrantFiled: November 19, 2015Date of Patent: August 8, 2017Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventor: Kosuke Iwase

Patent number: 9698451Abstract: The disclosed embodiments provide a system that manages use of a battery in a portable electronic device. During operation, the system uses a reference electrode in the battery to monitor an anode potential of an anode in the battery during charging of the battery in the portable electronic device. If the anode potential falls below an anode potential threshold, the system modifies a charging technique for the battery to extend a cycle life of the battery. For example, the system may reduce a charge current of the battery if the anode potential falls below the anode potential threshold to prevent degradation caused by a negative anode potential during charging of the battery.Type: GrantFiled: July 6, 2011Date of Patent: July 4, 2017Assignee: Apple Inc.Inventors: Ramesh C. Bhardwaj, Sheba Devan, Taisup Hwang, Richard M. Mank
