Abstract
The present disclosure provides devices, systems, and methods for identifying conditions in a battery that predict fault or failure, alerting a user to the condition, and providing solutions to mitigate the potential harm that would otherwise result from the fault or failure. Further provided are battery casing designs for improved safety. These systems, devices, and methods are applicable to batteries generally, and are particularly useful in the field of implanted medical devices for mitigating the dangers of battery faults or explosions occurring within the body.
Claims45
A method for mitigating a battery condition in an implanted multi-cell battery pack, the method comprising:
- identifying a parameter of a cell that has exceeded a threshold;
- determining based on the parameter that the cell has a condition;
- isolating the cell having the condition from one or more other cells;
- and
- providing backup power to mitigate a loss of voltage from the isolated cell.
A system for powering an electronic device, the system comprising:
- a battery pack comprising a plurality of cells;
- a battery management system configured to:
- identify a parameter of one of the plurality of cells that has exceeded a threshold;
- determine based on the parameter that the cell has a condition;
- isolate the cell having the condition from one or more other cells;
- and
- provide backup power to mitigate a loss of voltage from the isolated cell.
A system for alerting a user to a condition of an electronic device, the system comprising:
- a battery pack connected to an implanted electronic device;
- and
- a battery management system connected to the battery pack configured to:
- identify a parameter of a cell in the battery pack that has exceeded a threshold;
- determine based on the parameter that the cell has a condition;
- and
- trigger an alert.
