The invention, which relates to the technical field of power management and control, specifically discloses a power balance system for a mobile power unit. The power balance system comprises a plurality of mobile power units and a power balancing device. The power balancing device consists of a processing module, a switch module, a balancing module and a first communication module. In addition, the invention also discloses a control method of the power balance system for a mobile power unit. The method comprises: S1, controlling battery packs to be connected in parallel; S2, detecting voltagesvalues of automatically replacing battery assemblies; S3, determining whether the voltage values fall into a balancing battery range value; if so, performing an S4; and if not, performing S7; S4, determining whether voltage values fall into a starting balancing range value; if so, performing an S5; and if not, performing an S6; S5, balancing a second mobile power unit with a maximum voltage or minimum voltage and carrying out circulation to the S2; S6, completing power balancing; and S7, carrying out power adjustment by means of charging or power consumption and carrying out circulation to the S2. The system has a simple structure; the balanced currents are constant; and high-efficiency balancing is realized.
Description
technical field [0001] The invention relates to the technical field of power supply management and control, in particular to a power balance system of a mobile power supply device and a control method thereof.
