1. A base station, comprising:

  • a power supply device, configured to supply currents to a load of the base station to ensure normal running of the base station, the load of the base station comprising a transceiver device, configured to receive or transmit a signal; and

    a control device, configured to control the transceiver device to receive or transmit the signal;

    wherein the power supply device comprises;

    a lead acid battery;

    a lithium ion battery; and

    an electrical energy control unit, configured to receive currents supplied by a power generation apparatus, distribute the currents supplied by the power generation apparatus to the load and the lithium ion battery to ensure normal running of the load and to enable the lithium ion battery to be charged, and when the lithium ion battery is fully charged, to distribute the currents supplied by the power generation apparatus to the load and the lead acid battery so that the lead acid battery is charged;

    wherein when the electrical energy control unit detects that the currents supplied by the power generation apparatus are interrupted, the electrical energy control unit is further configured to first transfer a current provided by the lithium ion battery to the load, and then transfer a current provided by the lead acid battery to the load when the lithium ion battery is exhausted.
