Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
Fig. 1 shows this primary structure of power autonomous 5 and forms, comprise charging inlet 1, electric power storage storage battery 2, AC inverter 3, output interface 4 etc., wherein charging inlet 1 is connected with electric power storage storage battery 2, electric power storage storage battery 2 is connected with the input of AC inverter 3, and the output of AC inverter 3 is connected to output interface 4.
Fig. 2 shows this power autonomous 5 schematic diagram that charges.Its method of operation is: in the place that power supply grid can arrive, the 220V AC supply voltage of power supply grid output is linked into this charging inlet of power autonomous 51 (for example the mode by plug and socket realizes), electric power storage storage battery 2 is charged, and electric power storage storage battery 2 stores the electric energy that charges into.
The electric power storage storage battery is very common in the prior art, and technology is also very ripe, does not repeat them here.
This charging process promptly can adopt and promptly connect automatic charging modes (if the electric power storage storage battery store electrical energy deficiency of promptly filling, then in a single day charging inlet 1 receives the 220V AC supply voltage, just enter charged state immediately), also can adopt manual powered mode, promptly power autonomous 5 are provided with charge switch, only under the situation of switch closure, just can enter charged state.
