1. A method for charging an electric vehicle, comprising:

  • using a mobile charging apparatus to transmit status information thereof to a centralized battery distribution station;

    using the centralized battery distribution station to determine, according to the received status information, whether power of a battery of the mobile charging apparatus is less than a first threshold;

    processing, if the power of the battery of the mobile charging apparatus is less than the first threshold, the battery of the mobile charging apparatus to make the power of the battery of the mobile charging apparatus greater than a second threshold, wherein the second threshold is greater than the first threshold; and

    using, if the power of the battery of the mobile charging apparatus is not less than the first threshold, the mobile charging apparatus to charge the electric vehicle;

    wherein the processing the battery of the mobile charging apparatus to make the power of the battery of the mobile charging apparatus greater than the second threshold further comprises;

    replacing a battery of which the power is less than the first threshold in the mobile charging apparatus to make the power of the battery of the mobile charging apparatus greater than the second threshold;

    wherein the replacing the battery of which the power is less than the first threshold in the mobile charging apparatus to make the power of the battery of the mobile charging apparatus greater than the second threshold comprises;

    using the centralized battery distribution station to send a distribution request to a battery replacing and recharging center station via wireless communications;

    using the battery replacing and recharging center station to distribute a fully-charged battery to be distributed according to the distribution request;

    using a battery distribution logistics vehicle to distribute the fully-charged battery to a position of the mobile charging apparatus and replace with the fully-charged battery the battery of which the power is less than the first threshold in the mobile charging apparatus; and

    carrying the replaced battery of which the power is less than the first threshold to the battery replacing and recharging center station for recycling and recharging; and

    wherein the carrying the replaced battery of which the power is less than the first threshold to the battery replacing and recharging center station for recycling and recharging comprises;

    enabling the battery distribution logistics vehicle to travel to the position of the mobile charging apparatus of which battery is to be recycled, so that a distribution person uses a lifting and grabbing device to successively carry the batteries to be recycled to a synchronous belt in the battery replacing and recharging center station;

    enabling the battery to be recycled to enter a diagnostic area, and charging the battery to be recycled via an energy storage heap or an electric supply according to time scheduling of a unified dispatching system;

    after completing charging the recycled battery, determining a maximum power capacity of the recycled battery;

    if the maximum power capacity is less than a third threshold, determining that the recycled battery is a non-reusable battery which is considered to be retired, and then using a synchronous-belt motor to drive the synchronous belt to pull the retired battery to a decontamination area for processing;

    if the maximum power capacity is greater than the third threshold, determining that the recycled battery is a reusable battery and then using the synchronous-belt motor to drive the synchronous belt to pull the reusable battery to a cascade utilization energy storage area for processing; and

    installing a control switch and a circuit for the reusable battery in the cascade utilization energy storage area to connect the reusable battery with other batteries in series or in parallel in the constructed energy storage heap for storing energy.
