Description
Technical field
The present invention relates to the battery testing technology, be specifically related to utilize for example discharge and recharge battery tester, the method and system that testing tools such as appearance are tested battery cells such as for example flow battery or battery pile.
Background technology
All-vanadium liquid flow energy storage battery (all vanadium redox flow battery, the active substance of both positive and negative polarity electrode reaction when VRB) being battery charging and discharging with the vanadium ion that is dissolved in the different valence state in the finite concentration sulfuric acid solution.All-vanadium liquid flow energy storage battery is except that the general advantage with liquid flow energy storage battery; Because the electrolyte metallic ion has only vanadium ion a kind of; The electrolyte contamination problem that causes because ion is gone here and there mutually in the time of can also avoiding discharging and recharging; And the vanadium electrolyte solution can be recycled and regeneration, economizes on resources.
Battery testing is the key link in electrochemical energy research and development and the production run.In the test of all-vanadium flow battery monomer, the standardized product of a cover does not occur at present, and topmost mode has three kinds: the first, and the test of Applied Electrochemistry testing apparatus; Second kind is to utilize to discharge and recharge electric appearance, and for example, lead-acid accumulator discharges and recharges electric appearance and tests; The third method of testing is to utilize constant current or constant voltage source to charge, and discharges with permanent resistance or electrical appliance (being permanent power).
Use electro-chemical test equipment to be mostly colleges and universities or scientific research institutions, like the use electrochemical workstation, or the galvanochemistry comprehensive tester, this kind equipment generally provides more electrochemical test function, but the strength of current that provides usually is lower, and price is higher.With Princeton allpled reserch (PAR) PARSTAT 2273 type electrochemical workstations is example, and one price is about 300,000 yuans, but the electric current output of 2A can only be provided, and increase current value, must purchase other accessory.Inapplicable when high-power all-vanadium flow battery is tested, or testing cost is comparatively expensive.

Discharging and recharging appearance is the most frequently used means of testing of present enterprise, and low price can be realized simple programming, and this appearance that discharges and recharges is low excessively for preventing cell voltage, generally adopts voltage, current double closed-loop control.Promptly when setting charging and discharging currents, the setting voltage lower limit is U simultaneously
0When battery voltage value U greater than U
0The time, then carry out charge-discharge test according to the current value of setting, when battery voltage value U less than U
0The time, then do not meet entry condition, discharge and recharge appearance and do not start.Generally discharge and recharge appearance to the lead-acid accumulator design, lead-acid accumulator monomer rated voltage is 2V, and an electric battery is made up of 6 cells, and rated voltage is 12V.For all-vanadium flow battery, open-circuit voltage OCV value generally was no more than 1.65V when battery cell was full of, and generally was no more than 1.3V when having put, and the WV after the discharge can be lower, sometimes less than 1V, so not exclusively suitable.Therefore often way is a requirement producer equipment customized, increases this circuit that rubs, and therefore, uses one to discharge and recharge appearance and just need one customized, brings higher technical cost and cycle of length thus.
In addition; Electro-chemical test equipment and discharge and recharge voltage, electric current and cell (or the pile that appearance can only recording cell; Promptly; The electric battery of being made up of through serial or parallel connection battery cell) variation of temperature characteristic can't record for other technological parameter states (like electrolyte flow rate or flow, electrolyte temperature, fluid reservoir electrolyte inside liquid level change etc.) of vanadium cell operation.That is in test process, can't the be coupled corresponding relation of battery performance and battery operation state.
In addition; Flow battery electrolytic solution in operational process is round-robin inside and outside battery; And comparatively responsive to temperature, electrolyte had taken place separate out and block pipeline, carbon felt electrode surface impurity blocking pipeline, electrolyte leakage or subsidiary reaction problems such as (as water electrolysis reaction takes place).Because all-vanadium flow battery capacity and power are relatively independent, and the follow-on test time will be longer than the battery of other kinds far away in some cases, therefore convenience and the security to test has very high requirement again.
