Referring to fig. 1, fig. 1 is a schematic view showing the structure of a storage battery with a liquid level detection function and a liquid level control function according to the present utility model. The utility model relates to a storage battery which detects liquid level and has a liquid level control function, comprising: the battery comprises a battery shell, a battery cover, a liquid level control device, a ventilation device and an electrolyte circulation device.
In this embodiment, the battery case is a closed container. The battery cover is a cover matched with the battery case and is used for sealing the battery case. The battery cover is provided with a plurality of through holes for connecting the liquid level control device, the ventilation device and the electrolyte circulation device.
In this embodiment, the liquid level control device is disposed on the battery cover, and is used for detecting and adjusting the liquid level of the electrolyte, so as to keep the liquid level within a preset range, thereby reducing gas generation and electrolyte consumption inside the storage battery. The liquid level control device includes: a liquid level sensor for detecting the liquid level of the electrolyte, a micro controller and a liquid supplementing valve. The fluid supplementing valve is connected with an external fluid supplementing device.
In this embodiment, the liquid level sensor is a floating ball suspended in the battery, and the upper end of the liquid level sensor is connected with the micro controller through a wire. When the liquid level of the electrolyte changes, the floating ball moves up and down along with the change of the liquid level of the electrolyte, and a state signal is sent to the micro controller. And the micro controller controls the switch of the liquid supplementing valve according to the state signal and the preset liquid level range. When the liquid level of the electrolyte is detected to be lower than a preset range, the micro controller opens a liquid supplementing valve to enable an external liquid supplementing device to supplement water or dilute acid into the electrolyte; when the liquid level of the electrolyte is detected to be higher than the preset range, the micro controller can close the liquid supplementing valve to stop supplementing water or diluting acid.
In this embodiment, the fluid replenishing valve is a reversible valve that is opened or closed according to the pressure difference of the electrolyte. When the pressure of water or diluted acid in the external fluid infusion device is higher than the pressure in the electrolyte, the fluid infusion valve is automatically opened to allow the water or diluted acid to flow into the electrolyte; when the pressure of water or diluted acid in the external fluid infusion device is lower than or equal to the pressure in the electrolyte, the fluid infusion valve can be automatically closed to prevent the water or diluted acid from flowing out of the electrolyte.
In this embodiment, the ventilation device is disposed on the battery cover, and is used to control the pressure inside the battery, so as to prevent the battery from bursting or leaking. The ventilation device includes an exhaust pipe that can exhaust gas generated inside the battery and an intake port that can let outside air into the battery. The exhaust pipe is arranged on the battery cover and connected with the inside of the battery, and is used for exhausting gas generated in the battery; the air inlet is arranged on the battery shell and connected with the inside of the battery, and is used for allowing outside air to enter the inside of the battery so as to keep the internal pressure stable.
In this embodiment, when the battery is charged and discharged, moisture in the electrolyte is decomposed into oxygen and hydrogen with electrochemical reaction, and these gases are generated inside the battery and may cause an increase in the internal pressure of the battery. In order to control the pressure inside the battery, the ventilation device may discharge the surplus gas to the outside through the exhaust duct and allow the outside air to enter the inside of the battery through the air inlet to keep the internal pressure stable.
In this embodiment, the electrolyte circulation device is disposed on the battery cover, and is configured to perform reverse electrolysis using oxygen and hydrogen generated inside the battery, convert the oxygen and hydrogen into moisture, and return the moisture to the electrolyte. The electrolyte circulation device includes a conversion device that can convert oxygen and hydrogen into moisture, and a pipe that conveys oxygen and hydrogen generated inside the battery to the conversion device. The pipeline is arranged on the battery cover and is connected with the inside of the battery; the conversion device comprises: a reaction chamber, electrodes, a power supply for providing voltage and current required by the reaction, and a water tank for collecting moisture generated by the reaction. The reaction chamber is a closed container, and the inside of the reaction chamber is filled with diluted sulfuric acid solution serving as a reaction medium; the electrodes are two metal sheets, are respectively connected to the anode and the cathode of the power supply, and are inserted into the reaction chamber; the power supply is an adjustable direct current power supply; the water tank is a container for storing moisture, is connected with the reaction chamber, and is used for conveying the moisture into the electrolyte. When the pipeline conveys oxygen and hydrogen generated in the battery to the reaction chamber, the oxygen and the hydrogen can undergo reverse electrolytic reaction under the action of the electrode, namely: 2h2+o2→2h2o+electrical energy.
In this embodiment, the microcontroller is an STM32F103 series single-chip microcomputer.
