Patent number: 10254350Abstract: Systems and methods are disclosed for a warranty tracker embedded in a battery pack. In an embodiment, the warranty tracker may include a memory device and a warranty controller. The warranty controller may receive an electric current measurement indicating a rate of charge or discharge of the battery pack from a device that is external to the battery pack. A warranty value may then be calculated using the received electric current measurement and added to a stored cumulative warranty value. The memory device may store the cumulative warranty value, which may be used to evaluate warranty conditions. In various embodiments, the warranty tracker may also include a temperature sensor and/or a voltage sensor. The warranty controller may then use received temperature and/or voltage measurements in the calculation of the warranty value. In an embodiment, the stored cumulative warranty value may be used to determine expiration of a warranty.Type: GrantFiled: August 6, 2015Date of Patent: April 9, 2019Assignee: Powin Energy CorporationInventor: Virgil Lee Beaston

Patent number: 10153521Abstract: Systems and methods are disclosed for detecting a battery pack having an operating issue or defect. In an embodiment, a balancing charger may be configured to charge a battery pack. An amount of time that the balancing charger is operating may be recorded. The recorded time may then be compared to a threshold time that indicates a determined variance from an expected operating time. If the recorded time exceeds the threshold time, the battery pack may be determined to have an operating issue or defect. In an embodiment, the threshold time may be adjusted based on an average battery cell or battery module temperature of the battery pack. In various embodiments, an alert may also be issued in response to determining that the battery pack has an operating issue or defect and operation of the battery pack may be halted to prevent any potential adverse effects.Type: GrantFiled: August 6, 2015Date of Patent: December 11, 2018Assignee: Powin Energy CorporationInventor: Virgil Lee Beaston
