Abstract
Disclosed is an adaptive, conditional fast-charging method for hearable devices. In the method, a high charge rate (C-rate) is applied only when the battery state of charge (SOC) is below a low threshold (e.g., 10-30%) and desired conditions (e.g., temperature, age) are met. Further, charging immediately reverts to a standard rate once an SOC target or a temperature limit is reached. This selective, conditional approach provides a rapid initial charge that significantly enhances the user experience, reduces the risk of lithium plating, and avoids the cost and size constraints associated with batteries designed for sustained high C-rates.
