Description
Technical field
The utility model relates to electric pile structure and battery operation management, specifically a kind of flow cell pile of energy-storage battery.
Background technology
Vanadium redox battery, be called for short vanadium cell (VRB), is the powerful outstanding environmental protection energy-storage battery of current growth momentum.The series of advantages such as but vanadium cell has degree of depth high current density discharge, it is rapid, cheap to have extended cycle life, charge, environmental protection, be suitable for very much the fields such as wind power generation, photovoltaic generation, electrical network tune seam, traffic municipal administration, communication base station, ups power and military electric power storage, have market prospects widely.
Vanadium redox battery is used respectively
With
Electrolyte solution compositions both positive and negative polarity electricity is right, and its open circuit voltage has reflected the variation relation of different vanadium ion concentration in electrode potential and both positive and negative polarity electrolyte, is an important parameter of research vanadium cell capacitance loss.Because there are polarization phenomena in battery, make charging voltage always higher than open circuit voltage, discharge voltage is lower than open circuit voltage.There is utility model to propose in the electrolyte conveyance conduit of battery, sets a kind ofly with reference to electrolyte, by mensuration, determine the state-of-charge of battery with reference to the potential difference between the electrolyte flow through in electrolyte and pipeline.Though this technical scheme has realized the real-time detection of battery open circuit voltage, increased the complexity of pipe-line system.
Summary of the invention
The deficiency existed in order to solve prior art, the utility model proposes a kind of flow cell pile, and this electric pile structure can realize directly that the real-time online of battery open circuit voltage detects, and system configuration is simple.
For achieving the above object, the technical scheme that the utility model adopts is:
A kind of flow cell pile, comprise main battery and attached independent battery two parts, and closed-loop path connected, forms by described main battery with charging/discharging apparatus; Described attached independent battery and main battery mutually insulated, both electrolyte connect as one; On attached independent battery, be connected with the open circuit voltage checkout equipment.
Described attached independent battery is arranged between the collector plate of the end feed liquor plate of flow cell pile and main battery, is provided with seal between the collector plate of attached independent battery and the collector plate of main battery.
The beneficial effect that the utility model produces is:
The utility model when main battery access charging/discharging apparatus, can discharge and recharge normally, meanwhile, attached independent battery does not does not discharge and recharge, only by connected open circuit voltage checkout equipment, record the voltage on attached independent battery, the proportionate relationship of the monocell number by attached independent battery and the monocell number of main battery, convert and draw the open circuit voltage of flow cell pile.
The pile that the utility model overcome polarization because of flow battery, cause discharges and recharges the problem of degree detecting difficulty, by detecting attached independent battery open circuit voltage, can realize the real-time detection of flow cell pile open circuit voltage, thereby the degree that discharges and recharges of judgement flow cell pile, control the start and stop that flow cell pile discharges and recharges according to this.Due to, attached independent battery is integrated on flow cell pile, therefore, in charge and discharge process, does not need to suspend main battery, gets final product the stable charging and discharging state that obtains pile.The utility model has been made simple architecture advances on existing flow cell pile simultaneously, and testing circuit is simple and easy, easy to operate, safe and reliable, and efficiency improves greatly.

Embodiment
As shown in Figures 1 to 3, the utility model is a kind of flow cell pile, comprises main battery 2 and attached independent battery 4 two parts.Main battery 2 and attached independent battery 4 mutually insulateds, be arranged between the both side ends feed liquor plate 1 of pile, but the electrolyte of main battery 2 and attached independent battery 4 connects as one.
The charging/discharging apparatus AC/DC of the normal access battery system of main battery 2, namely closed-loop path is connected, formed to main battery 2 with charging/discharging apparatus AC/DC.Concrete: main battery 2 comprises several monocells and two collector plate 3-1, and in this embodiment, main battery 2 two ends arrange respectively collector plate 3-1, the collector plate 3-1 series-connection charge-discharge device A C/DC at main battery 2 two ends, formation closed-loop path.
Attached independent battery 4 is arranged between the collector plate 3-1 of the end feed liquor plate 1 of flow cell pile and main battery 2, is provided with seal 5 between the collector plate 3-2 of attached independent battery 4 and the collector plate 3-1 of main battery 2.Attached independent battery 4 connects as one with the electrolyte of main battery 2, is connected with open circuit voltage checkout equipment 6 on the collector plate 3-2 at attached independent battery 4 two ends.Concrete: attached independent battery 4 comprises that several series connection are holistic monocell, and in this embodiment, seal 5 is that insulation board, open circuit voltage checkout equipment 6 are voltmeters of measuring electrolyte voltage.Attached independent battery 4 is not in the charge and discharge process of main battery 2, discharge and recharge, only use open circuit voltage checkout equipment 6 to detect the open circuit voltage on attached independent battery 4, this voltage be electrolyte voltage, be the open circuit voltage of the utility model flow cell pile.
In this embodiment:
The attached independent battery 4 that the main battery 2 that the embodiment pile consists of 30 monocells and 1 monocell form forms.During the pile operation, as shown in Figure 3, only have main battery 2 access charging/discharging apparatus (DC/AC transducer) to discharge and recharge normally, and attached independent battery 4 does not does not discharge and recharge, only detects its voltage, this voltage is the open circuit voltage of flow cell pile.
