Detailed Description
The present invention will be described in detail with reference to the accompanying drawings and examples.
Before the present invention is described in detail, it should be noted that in the following description, the elements with the same function are represented by the same reference numerals.
Referring to fig. 1, an embodiment of the smart battery 100 of the present invention includes an intelligent control module 200 and a battery device 7. The battery device 7 includes an anode terminal 91, a cathode terminal 92, a battery pack 72, a temperature sensing unit 73, and a Battery Management System (BMS) 71. The battery pack 72 includes a first terminal 721 electrically connected to the anode terminal 91 and a second terminal 722 electrically connected to the cathode terminal 92, for example, the battery pack 72 further includes at least one rechargeable battery cell, and the at least one rechargeable battery cell is arranged in series, parallel, or series-parallel.
The temperature sensing unit 73 detects the temperature of the battery pack 72 to generate a first temperature signal indicating whether the operating temperature is abnormal and a second temperature signal indicating the operating temperature. The battery management system 71 is electrically connected to the battery pack 72, and is a conventional battery management device for measuring and managing the voltage and current of the battery pack 72, such as detecting the voltage and current of the at least one rechargeable battery cell, and accordingly calculating the capacity or implementing an over-voltage or over-current protection mechanism, or performing an over-temperature protection mechanism according to the first temperature signal.
The intelligent control module 200 includes an intelligent control unit 1, a switch unit 2, a current flow meter 3, an input unit 4, a display unit 5, and a communication unit 6.
The input unit 4 is electrically connected to the intelligent control unit 1 to input and generate an overvoltage threshold, an overcurrent threshold, a group of abnormal thresholds, and an overtemperature threshold. For example, the input unit 4 includes three keys, so that a user can input and generate various numerical values by pressing the three keys, but not limited thereto.
The current flow meter 3 is electrically connected between the battery pack 72 and the cathode terminal 92, and includes a first terminal 31 electrically connected to the second terminal 722 of the battery pack 72 and a second terminal 32, and measures the magnitude of the current flowing through the first terminal 31 and the second terminal 32 of the current flow meter 3 to generate a current signal indicating the magnitude of the current.
The switch unit 2 includes a first terminal 21 electrically connected to the cathode terminal 92, a second terminal 22 electrically connected to the second terminal 32 of the current flow meter 3, and a control terminal 23 receiving a control signal from the intelligent control unit 1, and controls the first terminal 21 and the second terminal 22 of the switch unit 2 to be conducted or not conducted according to the control signal.
The intelligent control unit 1 is electrically connected to the anode terminal 91, the cathode terminal 92, the battery management system 71, the current flow meter 3, and the control terminal 23 of the switch unit 2, and generates the control signal. When the control signal controls the switch unit 2 to be turned on, the intelligent control unit 1 obtains an input/output current, such as the magnitude and direction of the current, between the anode terminal 91 and the cathode terminal 92 according to the current signal from the current flow meter 3.
The intelligent control unit 1 also detects an input/output voltage between the anode terminal 91 and the cathode terminal 92. In more detail, the intelligent control unit 1 can be directly electrically connected to the anode terminal 91 and the cathode terminal 92 to detect the input/output voltage. Alternatively, the intelligent control unit 1 may be directly electrically connected to the anode terminal 91 and indirectly electrically connected to the cathode terminal 92, for example, directly electrically connected to the second terminal 22 of the switch unit 2, when the control signal controls the switch unit 2 to be turned on, the intelligent control unit 1 detects a voltage difference between the anode terminal 91 and the second terminal 22 of the switch unit 2, so as to obtain the input/output voltage. In addition, the intelligent control unit 1 also obtains, through the battery management system 71, whether an operating state of the battery pack 72 is in a charging state or a discharging state.
The intelligent control unit 1 is also electrically connected to the temperature sensing unit 73 to receive the second temperature signal to obtain the operating temperature of the battery pack 72. It should be additionally noted that: in the present embodiment, the first temperature signal and the second temperature signal generated by the temperature sensing unit 73 are different, that is, the second temperature signal is capable of indicating the operating temperature, and conversely, the first temperature signal is only capable of indicating whether the operating temperature is abnormal, but is incapable of indicating the operating temperature. In other embodiments, the temperature sensing unit 73 may generate only one temperature signal indicating the operating temperature, and the battery management system 71 determines whether the operating temperature of the battery pack 72 is abnormal according to the temperature signal. Furthermore, in the present embodiment, the temperature sensing unit 73 is an element of the battery device 7, and in other embodiments, the temperature sensing unit 73 may also be an element of the intelligent control module 200, or the temperature sensing unit 73 includes two temperature sensors respectively belonging to the battery device 7 and the intelligent control module 200.
The intelligent control unit 1 determines whether the battery pack 72 is not operated normally according to the output/input voltage, the output/input current, the operating state, the over-voltage threshold, the over-current threshold, the over-temperature threshold, and the set of abnormal thresholds.
When the intelligent control unit 1 determines that the input/output voltage is greater than the over-voltage threshold, it generates and outputs an over-voltage signal S3 to indicate that the battery pack 72 is in an over-voltage state. When the intelligent control unit 1 judges that the operating temperature is greater than the over-temperature threshold, an over-temperature signal S5 is generated and output to indicate that the battery pack 72 is in an over-temperature state.
When the output/input voltage and the output/input current are determined to be greater than the set of abnormal thresholds, an abnormal signal S6 is generated and outputted to indicate that the battery pack 72 is in a failure state, for example, the set of abnormal thresholds includes a first value and a second value, and when the output/input voltage is greater than the first value and the output/input current is greater than the second value, it indicates that the at least one rechargeable battery cell of the battery pack 72 has been irreversibly damaged or destroyed.
When the intelligent control unit 1 determines that the operating state is the discharging state and determines that the output/input current is greater than the overcurrent threshold, an overcurrent signal S4 is generated and outputted to indicate that the battery pack 72 is in an overcurrent state.
When the intelligent control unit 1 determines that the operating state is in the charging state and determines that the output/input current is greater than the overcurrent threshold, the control signal is generated to control the switch unit 2 to switch between conduction and non-conduction at a predetermined duty ratio. That is, the switch unit 2 is switched between conduction and non-conduction in a Pulse Width Modulation (PWM) manner, so that the average value of the input/output current is smaller than the overcurrent threshold.
When the intelligent control unit 1 determines that the operating state is in the charging state, determines that the output/input current is greater than the overcurrent threshold, and determines that the average value of the output/input current is greater than the overcurrent threshold, the intelligent control unit generates and outputs the overcurrent signal S4. In other words, when the operating state is the charging state, if the input/output current is detected to be greater than the over-current threshold, the intelligent control unit 1 tries to make the average value of the input/output current smaller than the over-current threshold by the control signal in a pulse width modulation manner, and then generates the over-current signal S4 to indicate that the battery pack 72 is in an over-current state when the average value of the input/output current is determined not to be smaller than the over-current threshold.
When the intelligent control unit 1 generates and outputs the over-voltage signal S3, the over-current signal S4, the over-temperature signal S5, or the abnormal signal S6, and determines that the operation state is the charging state, a charging control signal S2 is generated and output. The charging control signal S2 is suitable for controlling a component (such as a switchboard or a relay) in the charging circuit of the external charging device to open the charging circuit, thereby stopping the charging of the battery device 7 and preventing the battery pack 72 from further damage due to improper operation.
When the intelligent control unit 1 generates and outputs the over-voltage signal S3, the over-current signal S4, the over-temperature signal S5, or the abnormal signal S6, and determines that the operation state is in the discharging state, a discharging control signal S1 is generated and output. The discharge control signal S1 is suitable for controlling an element (such as a switchboard or a relay) in a discharge circuit of an external electrical device to open the discharge circuit, so as to stop the discharge of the battery device 7, thereby preventing the battery pack 72 from further damage due to improper operation.
When the intelligent control unit 1 generates and outputs any one of the over-voltage signal S3, the over-current signal S4, the over-temperature signal S5, the abnormal signal S6, the charge control signal S2, and the discharge control signal S1, the first terminal 21 and the second terminal 22 of the switch unit 2 are controlled to be not conducted by the control signal.
The communication unit 6 is electrically connected to the intelligent control unit 1, and is further adapted to establish a connection with an electronic device, so that the electronic device can obtain at least one of the input/output current, the input/output voltage, the operation status, the over-voltage signal S3, the over-current signal S4, the over-temperature signal S5, and the abnormal signal S6. In addition, the intelligent control unit 1 can also obtain the overvoltage threshold, the overcurrent threshold, the set of abnormal thresholds, and the overtemperature threshold through the electronic device, that is, input the values through the electronic device. The communication unit 6 supports wired or wireless communication technologies, such as ethernet, wireless network (Wi-Fi), Bluetooth (Bluetooth) communication, or RS-232 standard, but not limited thereto. The electronic device is, for example, a computer terminal, a mobile device, etc.
The display unit 5 is electrically connected to the intelligent control unit 1 to display at least one of the states of the input/output current, the input/output voltage, the operation state, and the indication of the overvoltage signal S3, the overcurrent signal S4, the over-temperature signal S5, and the abnormal signal S6. For example, the display unit 5 includes a Light Emitting Diode (LED) display or a liquid crystal display panel, and the user selects through the input unit 4 to cause the display unit 5 to switch or alternately display the information.
In summary, the intelligent control unit 1 actively detects the input/output voltage and the input/output current between the anode terminal 91 and the cathode terminal 92 of the battery device 7, and according to the input/output voltage, the input/output current, the operation state of the battery pack 72 and the operation temperature, when it is determined that the battery pack 72 is not operating normally, the intelligent control unit can not only control the switch unit 2 to be turned off, but also generate the corresponding charging control signal S2 or the corresponding discharging control signal S1 to control the corresponding loop of the external device to be turned off. In addition, the protection mechanism of the battery management system 71 is combined with the existing protection mechanism, so that the intelligent battery 100 has a triple safety mechanism, and the purpose of the present invention can be achieved.
However, the above embodiments are only examples of the present invention, and the scope of the present invention should not be limited thereto, and all the simple equivalent changes and modifications made according to the claims and the contents of the specification of the present invention are still included in the scope of the present invention.
