Description

Technical Field

[0001] The invention relates to the technical field of batteries, and in particular to a battery with a high temperature alarm function. Background Art

[0002] A battery is a device that contains an electrolyte solution and metal electrodes and can convert chemical energy into electrical energy. The main reason for battery heating is the internal chemical reaction. When the reaction rate inside the battery increases, the battery will become abnormally hot. If the battery has an abnormal high temperature, if it can be maintained before the high temperature exceeds the threshold, the battery can be prevented from exploding. Therefore, in order to avoid the occurrence of a high temperature explosion, a temperature sensor is generally used to detect the temperature of the battery in real time, so that when an abnormal high temperature occurs, a timely high temperature alarm can be realized. However, it is currently impossible to simultaneously detect and determine the operating status of the temperature sensor used to realize temperature detection. If the temperature sensor used to realize temperature detection fails, the battery will not be able to realize real-time temperature detection, resulting in the inability to realize a timely high temperature alarm when an abnormal high temperature occurs, which is defective.

[0020] In the embodiment of the present invention, the monitoring block 2 is externally connected to the power supply, and a microcontroller 2016 is arranged inside the monitoring block 2. The electric heating plate 2010, the temperature sensor 304 and the motor 4 are all electrically connected to the microcontroller 2016; the monitoring block 2 is also provided with a timing module 2012, a timing module 2013, a positioning module 2011 and a 5G module 2014, and the timing module 2012, the timing module 2013, the positioning module 2011 and the 5G module 2014 are all electrically connected to the microcontroller 2016. The initial timing value of the timing module 2012 is not limited, and its timing value can be set according to demand; the initial timing value of the timing module 2013 is ten seconds; the 5G module 2014 is connected to the wireless network transmission of the monitoring center 2015; when the timing value of the timing module 2012 is reached, the timing module 2012 feedbacks a signal to the microcontroller 2016, and the microcontroller 2016 controls the motor 4 shaft end to rotate clockwise for one circle, and at the same time controls the electric heating plate 2010 to start heating and the timing The timing module 2013 starts timing; when the timing value of the timing module 2013 is reached, the timing module 2013 feedbacks a signal to the microcontroller 2016, and the microcontroller 2016 controls the electric heating plate 2010 to turn off; when the temperature detected by the temperature sensor 304 exceeds the threshold, the temperature sensor 304 feedbacks a signal to the microcontroller 2016, and the microcontroller 2016 controls the 5G module 2014 to wirelessly transmit a message to the monitoring center 2015, and at the same time attaches the positioning module 2011 Positioning data; when the guide transmission member 401 engages the transmission guide rack 306 clockwise, the guide block 3 moves to the left along the monitoring opening 201, and simultaneously drives the plug-in block 302 to move to the left along the plug-in opening 209. At this time, the reset connection spring 208 is gradually compressed, and when the left end face of the third copper heat conductive plate 305 is in contact with the right end face of the second copper heat conductive plate 204, the guide transmission member 401 is not disengaged from the guide rack 306, and the spring connector 303 is gradually stretched.

[0021] The working principle of this embodiment: The present invention conducts the temperature of the battery body 1 through the cooperation of the first copper heat conductive sheet 102 fixedly connected to the battery body 1, and the reset connection spring 208 and the spring connector 303 are both in an extended state, and the right end surface of the third copper heat conductive sheet 305 is in contact with the left end surface of the first copper heat conductive sheet 102. Therefore, through the heat conduction between the first copper heat conductive sheet 102 and the third copper heat conductive sheet 305, the temperature measuring end of the temperature sensor 304 can realize real-time detection of the temperature of the battery body 1.

[0022] When the battery body 1 has an abnormally high temperature, the temperature detected by the temperature sensor 304 exceeds the specified threshold through heat conduction between the first copper heat conductive sheet 102 and the third copper heat conductive sheet 305. The temperature sensor 304 then feeds back a signal to the microcontroller 2016. The microcontroller 2016 controls the 5G module 2014 to wirelessly transmit a message to the monitoring center 2015, and at the same time attaches the positioning data of the positioning module 2011, so that the staff in the monitoring center 2015 can promptly know that the battery body 1 has an abnormally high temperature, and go to the maintenance in time according to the positioning data of the positioning module 2011.

[0023] In order to ensure the normal operation of the high temperature monitoring and alarm function of the battery body 1 of the present invention, the present invention detects and determines the operating state of the temperature sensor 304 used for temperature detection at intervals, and the specific operation is as follows: First, the staff sets a special time period through the timing module 212, such as 8 o'clock in the morning. When the timing value of the timing module 2012 is reached, the timing module 2012 feedbacks a signal to the microcontroller 2016, and the microcontroller 2016 controls the motor 4 to rotate one circle clockwise, and at the same time controls the electric heating plate 2010 to start heating and the timing module 2013 to start timing; When the shaft end of the motor 4 rotates clockwise, the guide transmission member 401 engages with the transmission guide rack 306 to synchronously drive the guide block 3 to move to the left along the monitoring opening 201. Under the limiting plug-in cooperation of the limiting socket 307 and the limiting column 207, while ensuring the stable movement of the guide block 3, the limiting plug-in block 301 also synchronously moves to the left along the reset matching groove 206 and compresses the reset connecting spring 208 at the same time.

[0024] When the guide block 3 moves to the left, it drives the limit plug block 301 to move to the left along the plug opening 209 through the spring connector 303 until the left end surface of the third copper heat conductive sheet 305 is in contact with the right end surface of the second copper heat conductive sheet 204. Since the side length of the third copper heat conductive sheet 305 is greater than the side length of the plug opening 209, the spring connector 303 will be gradually stretched during the guide block 3 moving to the left under the contact barrier between the third copper heat conductive sheet 305 and the second copper heat conductive sheet 204. When the electric heating plate 2010 starts heating, the heat generated by it will be transferred to the second copper heat conductive plate 204. At this time, the left end surface of the third copper heat conductive plate 305 is in contact with the right end surface of the second copper heat conductive plate 204. Therefore, through the heat conduction between the third copper heat conductive plate 305 and the second copper heat conductive plate 204, the temperature measuring end of the temperature sensor 304 will detect a temperature exceeding its specified threshold value. Therefore, at this time, a feedback signal is given to the microcontroller 2016, and the microcontroller 2016 controls the 5G module 2014 to wirelessly transmit a message to the monitoring center 2015, and at the same time, a positioning signal is attached. The positioning data of the module 2011 can be obtained, and the staff in the monitoring center 2015 can determine that the temperature sensor 304 currently used to realize temperature detection is in a normal operating state without fault based on the message feedback within the specific time period of the timing module 2012; when the temperature sensor 304 fails and cannot perform the temperature detection function, the staff in the monitoring center 2015 does not receive any message feedback within the specific time period of the timing module 2012, then it can be determined that the high temperature monitoring alarm function of the battery body 1 is faulty and needs to be repaired and maintained in time.

[0025] Because the guide transmission member 401 of the present invention is an incomplete gear, when the guide transmission member 401 and the guide rack 306 are disengaged, under the reset spring 208 and the spring connector 303, the third copper heat conductive plate 305 will be restored to a state where its right end face is in contact with the left end face of the first copper heat conductive plate 102.
