POWER CHARGER AND RECHARGEABLE BATTERY SYSTEM

摘要

A rechargeable battery (12) including intelligent switching circuitry (20) and sensing circuitry (26) configured to sense an input voltage from a charger (10). Upon connection of the charger (10) to the battery (12), the battery (12) is configured to: (i) disconnect output from battery cells in the battery to an electronic device (14) connected to the battery (12), (ii) power the electronic device (14) directly via the input voltage from the charger (10), and (iii) connect the rechargeable battery cells to the input voltage from the charger (10).
