It is in vertical state and another group is in level (being mutually clamped) so that of short duration cutout phenomenon occurs in electrolyte；Two groups
Rotor is rotated further, and electrolyte flows out valve body by electrolyte outlet pipe 3.
The operation principle of the present embodiment resultant stream battery is with embodiment 5, and its performance parameter refers to table 1.
Table 1 prior art and the performance parameter statistical table of embodiment 1-embodiment 7 resultant stream battery
As can be seen from Table 1: the branch current consumption (1.5-2.2A) of technical scheme (embodiment 1-7) is obvious
Less than prior art (2.8A)；Efficiency (the 77.3%-of the battery energy storage system of technical solution of the present invention (embodiment 1-7)
80.5%), it is significantly improved；The voltage concordance (0.21%-0.42%) of technical solution of the present invention (embodiment 1-7) is the most excellent
In prior art (0.60%).
In sum, the present invention uses the flow battery current interrupters design of uniqueness, and overall structure is simplified, and played
Cutout effect well so that electrolyte is batch (-type) output, makes the electrolyte in electrolyte pipeline become batch (-type) to disconnect.This
Bright flow battery uses above-mentioned flow battery current interrupters, and closed-loop path can be made to disconnect, and allowing electrolyte is batch (-type) one section
The each pile of input of one section, makes the electrolyte in electrolyte pipeline become batch (-type) to disconnect, and flow battery can be stoped because sharing electricity
The by-pass current solving liquid and cause, improves the efficiency of battery energy storage system and optimizes voltage concordance.
In addition, the technical scheme of other structures based on this principle falls within the scope of protection of the invention.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for the skill of this area
For art personnel, the present invention can have various modifications and variations.All within the spirit and principles in the present invention, that is made any repaiies
Change, equivalent, improvement etc., should be included within the scope of the present invention.
