DETAILED DESCRIPTION
[0026] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the following Figure 1 -Attached Figure 7 It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.
[0027] The embodiments of the present application disclose a control method, system, terminal and storage medium for a lithium iron phosphate dual battery. The present invention is used to determine whether the environment has an impact on the battery pack by detecting the temperature of the environment. When the ambient temperature is too high, the parameters of the main battery pack in use are monitored, and the main battery pack is switched to the backup battery pack when the parameters are abnormal. In addition, the backup battery pack is started as a heat source in a low temperature environment to heat the main battery pack, thereby maintaining the working performance of the main battery pack.
[0028] Reference Figure 1 , a control method for a lithium iron phosphate dual battery, comprising the following steps: Step 100: Obtain the ambient temperature.
[0029] Ambient temperature refers to the temperature of the space where the lithium iron phosphate battery is located. The ambient temperature can be obtained through a temperature sensor. The method for obtaining the ambient temperature is selected by the staff according to the actual situation and will not be elaborated here.
[0030] Step 101: When the ambient temperature exceeds a preset operating temperature range, obtain preset high temperature parameters of the main battery pack.
[0031] The operating temperature range refers to the temperature range in which the lithium iron phosphate battery can work normally. The operating temperature range is generally -10℃~60℃. The operating temperature range is selected by the staff according to the actual situation, so it will not be elaborated here. If the ambient temperature exceeds the operating temperature range, it means that the external temperature is too high, and the lithium iron phosphate battery is prone to failure.
[0032] The main battery pack refers to the lithium iron phosphate battery pack that is in the state of outputting electrical energy. The main battery pack is selected by the staff based on actual conditions and will not be elaborated here.
[0033] High temperature parameters refer to parameters such as voltage, current and temperature of the main battery pack in a high temperature environment. The high temperature parameters can be obtained through the sensor built into the lithium iron phosphate battery and read through the serial port preset on the lithium iron phosphate battery. The method of obtaining the high temperature parameters is selected by the staff according to the actual situation and will not be elaborated here.
[0034] Step 102: Determine whether the battery is abnormal based on the high temperature parameters from a preset abnormality judgment model.
[0035] The abnormality judgment model refers to a neural network model obtained through sample training in advance. The abnormality judgment model can judge whether the lithium iron phosphate battery has abnormalities such as unstable output voltage or excessive battery temperature through high temperature parameters.
[0036] Step 103: When a battery abnormality occurs, obtain the battery number of the preset main battery pack and the backup number of the preset backup battery pack.
[0037] The spare battery pack refers to a lithium iron phosphate battery pack used to replace the main battery pack. The spare battery pack is selected by the staff based on actual conditions and will not be described in detail here. Battery abnormalities mean that continued use is likely to cause the scope of internal abnormalities in the battery to expand, leading to combustion or even explosion. The battery number and spare number refer to pre-set digital numbers used to distinguish lithium iron phosphate battery packs. Each digital number corresponds to a lithium iron phosphate battery pack one by one. The battery number is the digital number of the main battery pack, and the spare number is the digital number of the spare battery pack. The battery number and spare number can be read through the serial ports preset on the main battery pack and the spare battery pack respectively. The method for obtaining the battery number and spare number is selected by the staff based on actual conditions and will not be described here.
[0038] Step 104: Control the preset output switching device to switch from the preset main battery group to the preset backup battery group to output power according to the battery number and the backup number, and match the warning number from the preset warning device matching model according to the battery number.
[0039] The output switching device refers to a device used to control the connection status of the lithium iron phosphate battery pack and the external equipment. The output switching device is selected by the staff according to the actual situation and will not be described in detail here. The warning device refers to a device used to remind the staff of the working status of the lithium iron phosphate battery pack. The warning device includes multiple parts to simultaneously display the working status of different lithium iron phosphate battery packs. The warning device is selected by the staff according to the actual situation and will not be described in detail here.
[0040] When an abnormality occurs in the main battery pack, the output switching device stops the main battery pack from outputting power and controls the backup battery pack to output power, thereby reducing damage to the main battery pack and maintaining the continuity of power output.
[0041] The warning number refers to the digital number set to distinguish different areas on the warning device. Each warning number corresponds to an area on the warning device. The setting method of the warning number is selected by the staff according to the actual situation and will not be described here. The warning device matching model refers to a neural network model obtained through sample training in advance. The warning device matching model can match the warning number on the warning device used to show the working status of the main battery pack.
[0042] Step 105: Control a preset warning device to issue a fault warning according to the warning number.
[0043] The warning device is used to remind the staff of the failure of the main battery pack, so that the main battery pack can be replaced and repaired in time to reduce the damage of the main battery pack. The fault warning is a warning issued by the warning device to remind the staff.
[0044] Reference Figure 2 , the low temperature preheating method comprises the following steps: Step 200: When the ambient temperature is lower than a preset operating temperature range, low temperature power is matched from a preset output power matching model according to the ambient temperature.
[0045] The ambient temperature is lower than the working temperature range, which means the outside temperature is low. The output power matching model refers to a neural network model obtained through sample training in advance. The output power matching model can match the low-temperature power of the main battery pack and the backup battery pack to output electrical energy. The main battery pack and the backup battery pack output electrical energy at the same time according to the low-temperature power, thereby increasing the temperature of the main battery pack and the backup battery pack.
[0046] Step 201: according to the low temperature power, the preset output switching device is controlled to switch to the preset main battery group and the backup battery group to output electric energy simultaneously, and the low temperature parameters of the preset main battery group are obtained.
[0047] Low temperature parameters refer to parameters such as voltage, current and temperature of the main battery pack in a low temperature environment. The low temperature parameters can be obtained through the sensor built into the lithium iron phosphate battery and read through the serial port preset on the lithium iron phosphate battery. The method of obtaining the low temperature parameters is selected by the staff according to the actual situation and will not be elaborated here.
[0048] Step 202: judging whether the battery temperature falls within a preset operating temperature range from a preset battery temperature judgment model according to the low temperature parameter.
[0049] The battery temperature judgment model refers to a neural network model obtained in advance through sample training. The battery temperature judgment model can extract the temperature information of the main battery pack from the low temperature parameters and judge whether the temperature of the main battery pack falls within the operating temperature range.
[0050] Step 203: When the battery temperature falls within a preset operating temperature range, the preset output switching device is controlled according to the battery number to switch to the preset main battery group to output electrical energy.
[0051] When the temperature of the battery is too low, it is easy to cause the viscosity of the electrolyte inside the battery to increase, or even partially solidify, thereby reducing the migration speed of lithium ions and the conductivity of the battery, resulting in reduced capacity of the lithium iron phosphate battery, increased internal resistance, difficulty in charging, and reduced safety. The temperature of the main battery pack is increased by the self-heating of the main battery pack during operation, and the temperature increase speed of the main battery pack is accelerated by the self-heating of the backup battery pack, so that the temperature of the main battery pack falls into the operating temperature range, allowing the main battery pack to work normally.
[0052] Reference Figure 3 , the power control method comprises the following steps: Step 300: Obtain battery parameters of a preset main battery pack.
[0053] Battery parameters refer to parameters such as voltage, current, temperature and power of the main battery pack. Battery parameters can be obtained through sensors built into the lithium iron phosphate battery and read through the serial port preset on the lithium iron phosphate battery. The method of obtaining battery parameters is selected by the staff according to actual conditions and will not be elaborated here.
[0054] Step 301: Match the battery power from a preset power matching model according to the battery parameters.
[0055] The power matching model refers to a neural network model obtained through sample training in advance. The power matching model can filter out battery power information from battery parameters.
[0056] Step 302: When the battery power falls into a preset power shortage interval, a backup parameter of a preset backup battery pack is obtained.
[0057] The power shortage interval refers to the power range in which the lithium iron phosphate battery cannot output a stable voltage. The power shortage interval is generally 0% to 12%. The power shortage interval is selected by the staff based on actual conditions and will not be elaborated here.
[0058] The backup parameters refer to the parameters such as voltage, current, temperature and power of the backup battery pack. The backup parameters can be obtained through the sensor built into the lithium iron phosphate battery and read through the serial port preset on the lithium iron phosphate battery. The method of obtaining the backup parameters is selected by the staff according to the actual situation and will not be elaborated here.
[0059] Step 303: Match the reserve power from a preset power matching model according to the reserve parameters.
[0060] The backup power is the power information of the backup battery group selected from the backup parameters through the power matching model.
[0061] Step 304: When the backup power exceeds the preset power shortage interval, the preset output switching device is controlled to switch to the preset backup battery group to output power according to the battery number and the backup number.
[0062] The backup power exceeding the power shortage interval represents that the backup battery pack can provide a stable voltage. At this time, the main battery pack is turned off and the backup battery pack is turned on through the output switching device to supply power through the backup battery pack, thereby reducing the situation where power interruption is caused by insufficient power of the main battery pack.
[0063] Reference Figure 4 , the backup battery control method comprises the following steps: Step 400: Obtain idle parameters of a preset idle battery pack.
[0064] Idle battery packs refer to lithium iron phosphate battery packs that are not in working condition except the main battery packs and the backup battery packs. Idle battery packs are used to maintain at least two battery packs in the output switching device when the battery packs are replaced, thereby reducing power supply interruptions. The idle battery packs are selected by the staff according to actual conditions and will not be elaborated here.
[0065] Idle parameters refer to parameters such as voltage, current, temperature and power of an idle battery pack. Idle parameters can be obtained through sensors built into the lithium iron phosphate battery and read through a serial port preset on the lithium iron phosphate battery. The method for obtaining idle parameters is selected by the staff based on actual conditions and will not be elaborated here.
[0066] Step 401: Match the idle power from a preset power matching model according to the idle parameters.
[0067] The idle power is the power information of the idle battery pack selected from the idle parameters by the power matching model.
[0068] Step 402: When the idle power is greater than the standby power, define the preset idle battery group as the standby battery group.
[0069] The idle power being greater than the backup power means that the backup battery pack has a low power. The higher idle battery pack is used as the backup battery pack, and the original backup battery pack is defined as the idle battery pack, thereby reducing the situation where the backup battery pack is insufficient.
[0070] Step 403: When the idle power falls into the preset power shortage interval, the preset power recovery device is controlled according to the idle number and the backup number to control the preset idle battery group to input power to the preset backup battery group.
[0071] The energy recovery device refers to a device used to input the residual energy in the idle battery pack into the backup battery pack to reduce the waste of energy. The energy recovery device is selected by the staff according to the actual situation and will not be elaborated here.
[0072] The idle power falling into the power shortage range indicates that the power of the idle battery pack is low at this time. The remaining power in the idle battery pack is input into the backup battery pack through the power recovery device, thereby increasing the power of the backup battery pack and reducing the power waste in the idle battery pack.
[0073] Step 404: when the idle power falls into a preset replacement interval, the idle number of the idle battery pack is obtained.
[0074] The replacement interval refers to the power interval in which the energy in the lithium iron phosphate battery is about to be exhausted. The replacement interval is within the power shortage interval, and the upper limit value of the replacement interval is less than the upper limit value of the power shortage interval. The replacement interval is selected by the staff based on actual conditions and will not be elaborated here.
[0075] The idle number refers to the digital number set in advance to distinguish the lithium iron phosphate battery pack. Each digital number corresponds to a lithium iron phosphate battery pack one by one. The idle number is the digital number of the idle battery pack. The idle number can be read through the serial port preset on the idle battery pack. The method of obtaining the idle number is selected by the staff according to the actual situation and will not be elaborated here.
[0076] Step 405: Match the prompt number from the preset warning device matching model according to the idle number.
[0077] The prompt number refers to the warning number on the warning device matched by the warning device matching model and used to display the working status of the idle battery pack.
[0078] Step 406: Control a preset warning device to issue a battery replacement reminder according to the reminder number.
[0079] When the idle power falls into the replacement interval, it means that the power in the idle battery pack is about to be exhausted. At this time, the warning device is used to remind the staff to replace the idle battery pack in time, so that the main battery pack and the backup battery pack are kept connected to the output switching device during the battery pack replacement process, thereby improving the stability of power output during the battery pack replacement process. The battery replacement reminder is the reminder issued by the warning device.
[0080] When the electric energy in the idle battery pack is input into the backup battery pack through the electric energy recovery device, the backup power is monitored in real time. When the backup power is full, a battery replacement prompt is directly issued to replace the idle battery pack.
[0081] Reference Figure 5 , the battery heat dissipation method includes the following steps: Step 500: When the ambient temperature exceeds a preset operating temperature range, the cooling wind force is matched from a preset cooling wind force matching model according to the ambient temperature.
[0082] The heat dissipation device refers to a device that accelerates the heat dissipation of the battery pack by blowing air to the battery pack. The heat dissipation device is divided into multiple parts, each of which provides heat dissipation effects for different battery packs. The heat dissipation device is selected by the staff according to the actual situation and will not be described here. The heat dissipation wind force matching model refers to a neural network model obtained through sample training in advance. The heat dissipation wind force matching model can match the heat dissipation wind force required by the heat dissipation device to provide a heat dissipation effect to cope with the ambient temperature.
[0083] Step 501: matching the driving power from a preset driving power matching model according to the heat dissipation wind force.
[0084] The driving power matching model refers to a neural network model obtained in advance through sample training. The driving power matching model can match the driving power required to drive the heat dissipation device to blow out heat dissipation wind.
[0085] Step 502: Match the heat dissipation number from a preset heat dissipation number matching model according to the battery number.
[0086] The heat dissipation number refers to a digital number set in advance to distinguish different parts of the heat dissipation device. Each heat dissipation number corresponds to a part of the heat dissipation device. The setting method of the heat dissipation number is selected by the staff according to the actual situation and will not be described here. The heat dissipation number matching model refers to a neural network model obtained through sample training in advance. The heat dissipation number matching model can match the heat dissipation number corresponding to the heat dissipation device part that provides heat dissipation effect for the main battery pack.
[0087] Step 503: Control the preset backup battery pack according to the driving power to supply power to the preset heat dissipation device according to the heat dissipation number for heat dissipation.
[0088] The heat dissipation device is powered by the backup battery pack, thereby driving the heat dissipation device to blow air toward the main battery pack, thereby accelerating the heat dissipation of the main battery pack and reducing overheating of the main battery pack.
[0089] Reference Figure 6 , the humidity control method comprises the following steps: Step 600: Obtain ambient humidity.
[0090] Ambient humidity refers to the humidity of the space where the lithium iron phosphate battery is located. The ambient humidity can be obtained through a humidity sensor. The method for obtaining the ambient humidity is selected by the staff according to the actual situation and will not be elaborated here.
[0091] Step 601: When the ambient humidity exceeds a preset working humidity range, a dehumidification temperature is matched from a preset dehumidification temperature matching model according to the ambient humidity.
[0092] The working humidity range refers to the humidity range in which the lithium iron phosphate battery can work normally. The working humidity range is generally 40℃ (20~90)%RH. The working humidity range is selected by the staff according to the actual situation and will not be described here. If the ambient humidity exceeds the working humidity range, it means that the external humidity is too high, and the lithium iron phosphate battery is prone to failure.
[0093] The dehumidification temperature matching model refers to a neural network model obtained through sample training in advance. The dehumidification temperature matching model can match the dehumidification temperature required to reduce the ambient humidity.
[0094] Step 602: matching the dehumidification power from a preset dehumidification power matching model according to the dehumidification temperature.
[0095] The dehumidification power matching model refers to a neural network model obtained in advance through sample training. The dehumidification power matching model can match the dehumidification power of the power supply used by the backup battery pack to generate heat through power supply to reach the dehumidification temperature.
[0096] Step 603: Match the dehumidification number from the preset heat dissipation number matching model according to the spare number.
[0097] The dehumidification number refers to the heat dissipation number corresponding to the heat dissipation device part used to blow air to the backup battery pack to provide a heat dissipation effect, which is matched by the heat dissipation number matching model.
[0098] Step 604: Control the preset backup battery pack according to the dehumidification power to supply power to the preset heat dissipation device according to the dehumidification number.
[0099] The backup battery pack supplies power to the heat dissipation device to make the backup battery self-heated, so that the backup battery reaches the dehumidification temperature, and the heat dissipation device blows air to the backup battery to reduce the heat accumulation around the backup battery causing the backup battery to overheat, thereby improving the stability of the backup battery use.
[0100] Reference Figure 7 , the humidity control method further comprises the following steps: Step 605: When the ambient humidity exceeds a preset working humidity range, the heat dissipation angle of the heat dissipation device is obtained according to the dehumidification number.
[0101] The heat dissipation angle refers to the direction angle value of the heat dissipation device blowing air toward the standby device corresponding to the dehumidification number. The heat dissipation angle can be obtained through an angle sensor. The method for obtaining the heat dissipation angle is selected by the staff according to actual conditions and will not be elaborated here.
[0102] Step 606: Match the diffusion angle from a preset diffusion angle matching model according to the backup number and the battery number.
[0103] The diffusion angle matching model refers to a neural network model obtained in advance through sample training. The diffusion angle matching model can match the diffusion angle when the air around the backup battery pack is blown toward the main battery pack through the heat dissipation device.
[0104] Step 607: Matching an adjustment angle from a preset adjustment angle matching model according to the heat dissipation angle and the diffusion angle.
[0105] The adjustment angle matching model refers to a neural network model obtained in advance through sample training. The adjustment angle matching model can calculate the adjustment angle value required to adjust the heat sink from the heat dissipation angle to the diffusion angle.
[0106] Step 608: When the adjustment angle falls into the preset flip angle range, the preset backup battery pack is controlled according to the dehumidification power to reversely supply power to the preset heat dissipation device according to the dehumidification number, and the reversal angle is matched from the preset reversal angle matching model according to the adjustment angle.
[0107] The flip angle range refers to the angle value range that needs to be flipped when the heat dissipation device is adjusted according to the adjustment angle. The flip angle range is generally 90° to 270°. The flip angle range is selected by the staff according to actual conditions and will not be elaborated here.
[0108] When the adjustment angle falls into the flip angle range, it means that the heat sink needs to be flipped. At this time, the backup battery pack is used to reverse the power supply to reverse the heat sink to achieve the flip effect. The reversal angle matching model refers to a neural network model obtained through sample training in advance. The reversal angle matching model can match the reversal angle value that needs to be adjusted to achieve the diffusion angle after the heat sink is reversed.
[0109] Step 609: Control the preset heat dissipation device to adjust the angle according to the dehumidification number according to the reversal angle.
[0110] Adjust the direction of the heat sink so that the heat sink blows the air around the backup battery pack toward the main battery pack.
[0111] Step 610: When the adjustment angle does not fall within the preset flip angle range, the preset heat dissipation device is controlled to adjust the angle according to the dehumidification number according to the adjustment angle.
[0112] The air around the backup battery pack is heated by the backup battery pack, resulting in lower air humidity. At this time, the air around the backup battery pack is blown to the main battery pack through the heat dissipation device to reduce the humidity of the air around the main battery pack, thereby further reducing the situation where the main battery pack fails due to excessive ambient humidity.
