Claim 7:
8. The safety low-voltage electric appliance with an energy storage system for outputting a low-voltage power supply according to claim 4, wherein the terminal region power supply stabilization sub-module comprises:
a regional power supply sub-module used for regional power supply to the power supply terminal in the region;
a regional power supply switching sub-module used for inter-regional power supply switching of the regional power supply; and
a regional power supply balancing sub-module used for realizing balanced and stable inter-regional power supply during the inter-regional power supply switching process, and comprising multiple groups of input terminals, multiple groups of energy storage inductors, a centralized and decentralized reference ground potential terminal, multiple groups of thyristors, a bidirectional rectifying circuit, multiple groups of energy storage regions, and a one-superior and multi-inferior control center, wherein each said group of input terminals is connected to multiple power supply regions; the multiple groups of energy storage inductors are connected to the multiple groups of input terminals respectively to store and release electric energy; the centralized and decentralized reference ground potential terminal is connected to the multiple power supply regions; the multiple groups of thyristors correspond to the multiple groups of energy storage inductors respectively, one end of each said group of thyristors is electrically connected to the other end, other than an end connected to the corresponding input terminal, of the corresponding energy storage inductor, and the other end of each said group of thyristors is electrically connected to the reference ground potential terminal; the bidirectional rectifying circuit is electrically connected to a connection node of the multiple groups of thyristors and the corresponding energy storage inductor; each said energy storage region has a positive collection terminal and a negative collection terminal, the negative collection terminal of one said energy storage region is connected to the positive collection terminal of another said energy storage region through a controllable switch to form the connection node, which is connected to the reference ground potential terminal, and the positive collection terminals and negative collection terminals, that are not connected, of the multiple groups of energy storage regions are connected to the multiple groups of thyristors through the bidirectional rectifying circuit; the one-superior and multi-inferior control center is connected to the multiple groups of thyristors, and enables the multiple groups of energy storage inductors to store electric energy from the multiple groups of input terminals and release electric energy to the corresponding energy storage regions by turning on or off the multiple groups of thyristors; when electric energy in one said energy storage regions is sufficient, the corresponding group of thyristors is turned off; when electric energy in one said energy storage regions is sufficient and electric energy is needed by the load terminals, the corresponding group of thyristors is controlled to be turned on reversely, and then, the energy storage region releases electric energy to the load terminals, such that balanced and stable inter-regional power supply is realized during the switching process.
