Although the two schemes can realize the power supply of the battery to the load, the first scheme requires multiple battery packs. The energies cannot be allocated to each other, which will cause the entire device to stop running, resulting in the failure of the large-capacity battery pack to be fully utilized
In the second solution, the battery output energy channel is single, and multiple power converters are required to meet the power supply requirements of many loads, so the power supply system is complicated, which is not conducive to improving the reliability of the system

Abstract
The invention discloses a battery and load balance management system which comprises a battery assembly, a power switch module, a load assembly and a central processor. The central processor detects the working state of the load assembly and the working voltage of the battery assembly, and controls the on and off of different paths in the power switch module according to the working voltage required by the load assembly in different working states, so that different step voltages, formed by different battery strings, of the battery assembly can be dynamically matched with the power supply requirements of different loads in the load assembly. According to the present invention, different step voltages formed by different battery strings in the battery assembly are dynamically matched with the power supply requirements of different loads in the load assembly, so that the capacity of each battery string in the battery assembly can be fully utilized, the number of used battery packs is reduced, and the requirement of direct-current voltage conversion can be reduced to the maximum extent, and the use of power converters is reduced.
