POWER CONSUMPTION REDUCTION METHOD FOR A STORED BATTERY |
摘要 |
A power consumption reduction method controls a rechargeable battery to enter a sleep mode after the electronic system is shutdown with the output current of the rechargeable battery falling under a first current value or the rechargeable battery is in a non-communication status for over a first delay time. When in the sleep mode, a control unit further controls the rechargeable battery to enter a power saving mode when the output voltage of the rechargeable battery falls under a predefined voltage or the RSOC of the rechargeable battery is lower than a percentage of FCC, and the output current of the rechargeable battery falls under a second current value or the rechargeable battery is in the non-communication status for over a second delay time. The method shuts down all power-consuming circuits and components under long-time idling of the battery, capable of preventing overly discharging and malfunction of the rechargeable battery. |

1. A power consumption reduction method for a stored battery, wherein a rechargeable battery is installed in an electronic system and comprises a control unit, a battery set, and a Metal-Oxide-Semiconductor Field Effect Transistor (MOSFET) module, the MOSFET module comprising a discharging MOSFET and a charging MOSFET, the method comprising using the control unit to perform the following steps:
when an output current of the battery set is detected by the control unit to be under a first current value for over a first delay time, or when the battery set is detected by the control unit to be in a non-communication status for over the first delay time, the control unit controlling the rechargeable battery to enter a sleep mode; and when the rechargeable battery is configured in the sleep mode, and either an output voltage of the battery set is detected by the control unit to be under a predefined voltage or a relative state of capacity (RSOC) of the battery set is detected by the control unit to be lower than a critical percentage value, and either the output current is detected by the control unit to be under a second current value for over a second delay time or the battery set is detected by the control unit to be in a non-communication status for over the second delay time, the control unit controlling the rechargeable battery to enter a power saving mode.
