Charging control method, apparatus, and system, server, and medium

A charging control apparatus applied to a second terminal, wherein the second terminal stores a second charging policy and second time attribute information generated based on a generation time point of the second charging policy, the charging control apparatus comprises at least one processor and at least one memory coupled to the at least one processor, the at least one memory stores programming instructions for execution by the at least one processor to cause the charging control apparatus to:

• send the second time attribute information to a first terminal;
• receive target charging policy information from the first terminal, wherein the target charging policy information indicates a target charging policy that is determined by the first terminal based on first time attribute information and the second time attribute information, the first time attribute information is generated based on a generation time point of a first charging policy stored in the first terminal, the target charging policy comprises a plurality of ranges of a state of charge, the state of charge is a ratio of a remaining capacity to a capacity in a fully charged state, and the target charging policy is a later generated charging policy in the first charging policy and the second charging policy;
• configure a charging parameter based on the target charging policy, wherein the charging parameter comprises at least one of a charging voltage, a charging current, or a charging temperature, and each range of the state of charge comprises a plurality of state of charge levels, the target charging policy comprises a plurality of phase charging policies that are in one-to-one correspondence with the plurality of ranges of the state of charge, and each phase charging policy of the plurality of phase charging policies sets one or more charging parameters for the corresponding range of the state of charge, and configuring the charging parameter based on the target charging policy comprises:
• determining a current level of the state of charge;
• determining a current range of the state of charge that the current level of the state of charge belongs to;
