Vacuum battery structural assembly and vacuum multi-cell battery module

An apparatus is provided for measuring the power of electrolytes at different positions of a flow battery by switching six-way valves without reconnecting channels. With the measurements at the positions, weighting is processed to obtain power corresponding to charging statuses for determining accurate power. The charging and discharging of voltage and current of the battery are controlled for constant operations with high efficiency. Consequently, the efficiency of power conversion is improved; energy consumption is reduced; and the battery is always run within a safe power-range for avoiding accidents or damages to the battery. In addition, the present invention is further applicable to a device monitoring the features of a battery unit. The six-way valves online monitor the power at center positions by switching. The values measured at different positions are aimed at the abnormality of the battery unit for processing adjustment or offline replacement to maintain best operation performance.

Apparatus for electricity measurement of flow battery and method thereof

A method is provided for restoring an electrolyte of vanadium (V) redox flow battery (VRFB). Electrolyte data of an original system are analyzed in advance. A reusable positive electrode is further equipped with a V electrolyte. A reductant for a stack of VRFB is used in coordination as an electrolysis device. After a long-term reaction with a VRFB having a high valence (greater than 3.5), an electrolyte at the positive electrode is directed out to a negative electrode of the electrolysis device; and, then, electrolysis is processed after accurate calculation. In the end, the internal fluid balancing method of the original system is combined. Thus, a harmless and quick valence restoration is processed for the electrolyte of the original system, which is a final resort for the restoration of V electrolyte.

A storage module of distributed flow battery is provided. An electrochemical reaction is processed with the positive and negative electrolytes to produce and/or discharge direct current and further output the positive and negative electrolytes after the reaction. The module comprises two end plates; two frames disposed between the two end plates; two current collectors disposed between the two frames; two complex cast polar plates disposed between the two current collectors; two electrodes disposed between the two complex cast polar plates; a membrane disposed between the two electrodes; and three gaskets. Therein, two of the gaskets are set to sandwich and enclose one of the two complex cast polar plates; and the other one of the gaskets is set between the other one of the two complex cast polar plates and an adjacent one of the current collectors.
