Abstract
A power supply avoiding over-discharge of battery modules includes a main power supply system and a redundant power supply system. The invention uses a battery protection module to detect the status of a battery module in the redundant power supply system in normal conditions. The battery protection module includes an activation path connected to the main power supply system to receive standby power, a battery detection path connected to the battery module to receive a micro current and generate a protection activation signal when the battery module is in a charge-waiting state, and a protection activation path connected to a switch unit in the redundant power supply system to receive the protection activation signal to make the switch unit enter an OFF state.
