Abstract
Description
Technical Field
[0001] The invention belongs to the field of aluminum-air batteries and relates to a control method for intelligently accelerating the reaction rate of aluminum-air batteries. Background Art
[0002] When the aluminum-air battery reacts, after adding a certain proportion of salt water, the membrane acts as the anode and the composite material acts as the cathode to produce a chemical reaction to generate current. During the entire reaction process, the main participants are aluminum and water, and the final product is aluminum hydroxide. Under natural conditions, aluminum-air batteries require a long electrochemical reaction time to achieve the desired power, and a long wait is required in standby mode to achieve the expected output power. Summary of the invention
[0003] 1. Technical problems to be solved: Under natural conditions, aluminum-air batteries require a long electrochemical reaction time to achieve the desired power, and a long wait time in standby mode to achieve the expected output power.
[0004] 2. Technical solution: In order to solve the above problems, the present invention provides a control method for intelligently accelerating the reaction rate of aluminum-air batteries. When the aluminum-air battery is on standby, the current is increased until the set temperature is reached, and the temperature of the reaction cell is maintained at the set temperature. During the charging process, when the power of the load is greater than the maximum power Pmax, the load is turned off.
[0005] Preferably, the temperature of the reaction cell is increased by controlling the current passing through the load.
[0006] Preferably, the temperature of the reaction pool is maintained at a set temperature, and the specific method is: Step S01: four custom charging states: state a: load returns to 0; state b: load decreases; state c: load is maintained; state d: load increases; Step S02: detecting voltage; Step S03: After the external load is loaded, the voltage is detected again, and the voltage range is used to determine the state of the voltage; Step S04: If in state a, detect the voltage, if overloaded, unplug the load, if the power is greater than the maximum power Pmax, turn off the load; In state b, the load is reduced to determine whether it is greater than or equal to Pmax. If so, the load is turned off. In state c, the load is maintained to determine whether it is greater than or equal to Pmax. If so, the load is turned off. In state d, increase the load r and determine whether it is greater than or equal to Pmax. If so, turn off the load.
[0007] 3. Beneficial effects: The present invention intelligently accelerates the design of a control scheme for the electrochemical reaction rate of the aluminum-air battery, so that the aluminum-air battery reaches the desired power in a shorter time than the electrochemical reaction time in the natural state, and realizes controllable load action time, reduces the waiting time during standby, and satisfies the use of low power during the waiting time. After reaching the rated output power, the load can be cut off to avoid wasting resources. BRIEF DESCRIPTION OF THE DRAWINGS
[0008] Figure 1 It is a flow chart of the present invention. DETAILED DESCRIPTION
[0009] In standby mode, the temperature of the reaction cell (i.e., the stack chamber) will continue to decrease, making it impossible for users to charge normally. When the temperature of the reaction cell reaches T degrees Celsius, users can charge normally without waiting even in standby mode. The present invention provides a control method for intelligently accelerating the reaction rate of aluminum-air batteries, which increases the current to a set temperature when the aluminum-air battery is in standby mode, and maintains the temperature of the reaction cell at the set temperature.
[0010] In one embodiment, the present invention increases the temperature of the reaction pool by intelligently controlling the current passing through the load, thereby accelerating the reaction of aluminum in the reaction pool. By controlling the time of current increase, the time of continuous increase of the current on the load can be intelligently controlled, and the continuous heating time of the dummy load can be intelligently controlled, thereby intelligently controlling the temperature of the reaction pool (i.e., the stack chamber).
[0011] In one embodiment, the temperature of the reaction pool is maintained at a set temperature by: Step S01: four custom charging states: state a: load returns to 0; state b: load decreases; state c: load is maintained; state d: load increases; Step S02: Initialize the system and detect the voltage; Step S03: After the external load is loaded, the voltage is detected again, and the voltage range is used to determine the state of the voltage; Step S04: If in state a, detect the voltage, if overloaded, unplug the load, if the power is greater than the maximum power Pmax, turn off the load; In state b, the load is reduced to determine whether it is greater than or equal to Pmax. If so, the load is turned off. In state c, the load is maintained to determine whether it is greater than or equal to Pmax. If so, the load is turned off. In state d, increase the load r and determine whether it is greater than or equal to Pmax. If so, turn off the load.
[0012] In one embodiment, in order to ensure that the temperature of the reaction pool is maintained at T degrees Celsius, the aluminum-air battery needs to increase the current until the set output power is reached when it is in standby mode. After the aluminum plate is placed in the reaction pool, after a period of time, the temperature of the reaction pool rises, the load continues to be overloaded, and the output power at this time is also increased. At this time, if the aluminum-air battery is to output the set output power, the current will reach the maximum short-circuit state at a speed of milliseconds, at which time the voltage reaches the minimum, and the control circuit power switch enters a continuous start-stop state.
[0013] The present invention uses an intelligent control method to accelerate the electrochemical reaction rate of aluminum-air batteries, so that the aluminum-air batteries reach the desired power in a shorter time than the electrochemical reaction time in the natural state, and the load action time is controllable, thereby reducing the waiting time during standby and meeting the use of low power during the waiting time. After reaching the rated output power, the load can be cut off to avoid wasting resources.
