Charging device with battery management system for rechargeable battery

摘要

A charging device with a battery management system which remains a rechargeable battery in full capacity during standby after being fully charged is disclosed. The charging device includes a charging module, electrically connected to a power source, for charging the rechargeable battery; a voltage detecting module, for detecting a voltage of the rechargeable battery; and a determination module, for instructing the charging module to charge the rechargeable battery with a supplementary current, when the voltage of the rechargeable battery detected by the voltage detecting module reduces to a first predetermined voltage, until the voltage of the rechargeable battery reaches a second predetermined voltage. A reduction of the voltage of the rechargeable battery is due to self-discharge of the rechargeable battery during standby after being fully charged.

主权项

1. A charging device with a battery management system for a rechargeable battery, comprising:
a charging module, electrically connected to a power source, for charging the rechargeable battery; a power factor correction (PFC) circuit, connected between the power source and the charging module, for minimizing input current distortion and making current in phase with voltage during charging the rechargeable battery; a voltage detecting module, for detecting a voltage of the rechargeable battery; and a determination module, for instructing the charging module to charge the rechargeable battery with a supplementary current, when the voltage of the rechargeable battery detected by the voltage detecting module reduces to a first predetermined voltage, until the voltage of the rechargeable battery reaches a second predetermined voltage, wherein the voltage of the rechargeable battery is reduced due to self-discharge of the rechargeable battery during standby after being fully charged.
