Detailed Description
As shown in fig. 1, the present embodiment provides an adaptive micro power supply system 100, which includes: a first bus bar 10; a second bus bar 20; and at least one ac battery module 30.
The first bus bar 10 may be a bus bar of the first power, and the first bus bar 10 may be an ac power bus bar. The first bus 10 is mainly used for collecting and integrating multiple sets of power or output power of multiple sets of boost converters 210, and then is connected in parallel with the utility power.
The second bus bar 20, which may be a bus bar of second power, is mainly used for collecting and integrating power output by the multiple sets of ac battery modules 30. The second power of the second bus 20 is boosted by the boost converter 210 and then connected to the first bus 10 in parallel.
In order to effectively integrate the power output by the boost converter 210 into the first bus 10, the boost converter 210 can use the second phase-locked loop 220 to make the phase and frequency of the output of the boost converter 210 consistent with those of the first bus 10.
An alternating current battery module 30, comprising: a charge and discharge battery 310; a charging unit 320; and a current transformer 330. The ac battery module 30 is electrically connected to the second bus bar 20 by the plug-in connector, so that the ac battery modules 30 on the second bus bar 20 can be elastically expanded or adjusted, and each ac battery module 30 can be more conveniently replaced or maintained by the plug-in connector.
The charging/discharging battery 310 may be a lithium iron battery, a lithium battery or a lead acid battery, the charging/discharging battery 310 may be charged/discharged by the battery management system 331, and the battery management system 331 may further be configured to receive a dynamic signal of the load 40, so as to grasp states of a dynamic voltage, a dynamic current or a dynamic operating temperature of the load 40, and then dynamically adjust the power supply of the charging/discharging battery 310, for example, increase or decrease the power output, so as to maintain the stable power supply of the load 40.
A charging unit 320, which is mainly used for receiving the power source 50 and then charging the charging/discharging battery 310 when the charging/discharging battery 310 is used for storing power; the power source 50 may be a solar cell 510, a battery 520, a commercial power 530, or the like.
The converter 330 is mainly used for performing dc-ac conversion on the output power of the charge/discharge battery 310 when the charge/discharge battery 310 is used as the power source 50 to supply power to the load 40, and then outputting the output power to the second bus bar 20.
When the current transformer 330 of each ac battery module 30 is designed to have the same or standard specification, for example, the output voltage or power is the same, that is, the current transformer 330 is designed to be converged into the standard interface of the second bus bar 20, at this time, any type or brand of charging and discharging battery 310 can be used for charging and discharging the battery 310, so that the compatibility of the charging and discharging battery 310 can be increased.
Since the adaptive micro power supply system 100 may be connected in parallel with the utility power, and when the power charge of the battery reaches a first predetermined level, for example, 100% of the total power storage amount, the adaptive micro power supply system 100 provides power to the load 40 in preference to the utility power, in this case, thousands of adaptive micro power supply systems 100 may form a distributed small area power system, and provide power to the load 40 at a distance from the nearest load 40.
When the power of the battery is lower than the second predetermined level, for example, the power is discharged to 30% of the total power storage amount, the adaptive micro power supply system 100 will cut off the power supply and receive the charging of the utility power, so as to greatly increase the charging and discharging frequency of the battery, thereby avoiding the memory effect of the battery.
In order to effectively integrate the power output by the charging/discharging battery 30 with the second bus bar 20, the first phase-locking loop 332 may be used to electrically connect the charging/discharging battery 30 and the second bus bar 20, so that the output phase and frequency of the charging/discharging battery 30 are consistent with those of the second bus bar 20.
In the present embodiment, the AC battery modules 30 are inserted into and pulled out from the first-stage AC power, such as AC15V to AC120V, respectively, and the boost converter 210 dynamically boosts the first-stage AC power to the second-stage AC power, such as AC110V to AC380V, so as to provide power flexibly and efficiently.
When the power source 50 is a solar cell, the architecture of the adaptive micro power supply system 100 can avoid the danger of forming a high-voltage dc power source by connecting a plurality of solar cells in series. In addition, in the process of boosting the first-stage ac power to the second-stage ac power, the output adjustment can be performed by dynamically balancing the boost converter 210, so that the power output to the first bus 10 can be output more stably.
However, the above embodiments are provided to illustrate the features of the present invention, and the purpose thereof is to enable those skilled in the art to understand the content of the present invention and to implement the invention without limiting the scope of the present invention, so that other equivalent modifications or changes without departing from the spirit of the present invention should be included in the scope defined by the claims.
