Abstract

The invention relates to a communication energy storage power supply system, and especially relates to a direct-current energy storage power supply system for Internet data centers and communication base stations. The invention discloses an intelligent control communication power supply system comprising a battery pack, a charge and discharge port, a battery protection unit, a voltage conversion module, a battery management unit, a normally open delay switch, and a self-locking switch. The communication energy storage power supply system of the invention has two different system activation modes and an intelligent battery management system.

Description

technical field [0001] The invention relates to a communication energy storage power supply system, in particular to a DC energy storage power supply system for Internet data centers and communication base stations. Background technique [0002] The traditional uninterruptible power supply (UPS) battery management control method is to detect the battery temperature, current and voltage through the detection control unit, and the external rectification control unit adjusts the charging voltage according to the temperature and current data sent by the detection control unit, and the capacity detection should be stopped. Charging input, turn on the resistance discharge connected in parallel with the battery, and the external over-discharge protection unit closes the discharge in time according to the voltage data of the data detection unit. Under normal conditions of the battery, the AC power is converted into a low-voltage DC power to the battery through an external rectifier ...
