<p>An energy storage system and energy storage method for a communication base station, the energy storage system comprising: a first energy storage unit (11) comprising a plurality of lithium ion cells; a second energy storage unit (12) comprising a plurality of lead-acid cells; a switching unit (13) comprising two switching ends and a control end, one of the switching ends being two switching points respectively connected with the first energy storage unit (11) and the second energy storage unit (12), and the other switching end being connected to the power supply system (20) and the base station loader (21) of the communication base station; and a monitoring unit (14), the output end of the monitoring unit (14) being connected to the control end of the switching unit (13), and being used to input a control signal, and the monitoring unit (14) being used, according to whether the monitored power supply system (20) is powered on and the energy storage status of the first energy storage unit (11), to control the switching unit (13) to switch so as to charge and power the energy storage system. The energy storage method comprises: monitoring whether the power supply system (20) of the communication base station is powered off and the energy storage status of the first energy storage unit (11); when the power supply system (20) supplies power, the power supply system (20) firstly charges the first energy storage unit (11), and then charges the second energy storage unit (12) after the first energy storage unit is fully charged; and when the power supply system (20) is powered off, the first energy storage unit (11) firstly supplies power for the base station loader (21), and then the second energy storage unit (12) supplies power for the base station loader (21) after the power of the first energy storage unit is exhausted, thus improving the service life of the energy storage system, reducing the operating cost of the communication base station, and improving investment return ratio.</p> |
