Energy storage system and energy storage method based on communication base station

Abstract

The invention discloses an energy storage system and an energy storage method based on a communication base station, relates to the communication field, and can improve the service life of the energy storage system so that operation cost of the communication base station is reduced and investment return rate is improved. The energy storage system comprises a first energy storage unit including a plurality of lithium ion batteries; a second energy storage unit including a plurality of lead-acid batteries; a switch unit including two switch ends and a control end, and a monitoring unit; wherein one switch end of the switch unit is two switch points which are connected with the first energy storage unit and the second energy storage unit respectively, and the other switch end of the switch unit is connected with a power supply system and a base station load of the communication base station; the output end of the monitoring unit and the control end of the switch unit are connected to input control signals, the monitoring unit is used for controlling the switch unit to switch according to whether the monitored power supply system is charged and storage condition of the first energy storage unit, so that charging and power supply of the energy storage system are achieved.

Description

technical field [0001] The invention relates to the communication field, in particular to an energy storage system and an energy storage method for a communication base station. Background technique [0002] In order to ensure the reliability of the communication system, the communication base station generally needs to have its own energy storage system as a backup power supply when the power supply system is powered off. When the mains or other power supply systems are powered off, the backup power supply supplies power to the communication base station load to ensure communication normal operation of the base station. [0003] The energy storage systems of existing communication base stations mostly use lead-acid batteries, but lead-acid batteries are not suitable for deep charging and discharging, and because communication base stations generally require that the stored electric energy can be used for 3 to 5 days, the energy storage systems of communication base stations...

AI Technical Summary

Problems solved by technology

[0005] In order to keep the load of the communication base station uninterrupted and ensure the reliability of the energy storage system, such as the number of days of use of the stored electric energy, etc., the lead-acid battery is generally used after 2 to 3 years, although it still has 50% to 80% of the capacity and can be used. It still needs to be replaced with a new lead-acid battery. If it is used in a harsh environment such as repeated charging and discharging or working under severe temperature, the service life will be shorter, resulting in a short service life of the existing energy storage system and a low return on investment.
