[0012] In the embodiments listed below, the same or similar elements or components will be represented by the same reference numerals.

[0013] Figure 1 This is a schematic diagram of a smart battery device according to one embodiment of the present invention. Please refer to... Figure 1 The smart battery device 100 can be used to store electrical energy and can provide the stored electrical energy to a coupled powered device (not shown). In some embodiments, the powered device may be a variety of electronic devices or electric vehicles that need to be electrically actuated, but the embodiments of the present invention are not limited thereto.

[0014] The smart battery device 100 includes a battery cell 110, a temperature sensing unit 120, a processing unit 130, a discharge switch 140, and a charging switch 150.

[0015] Battery cell 110 provides electrical energy. In some embodiments, battery cell 110 may be composed of one or more battery cells connected in series and / or parallel. Alternatively, battery cell 110 may be a lithium battery, nickel-metal hydride battery, lead-acid battery, or any other suitable rechargeable battery.

[0016] Temperature sensing unit 120 senses ambient temperature to generate a temperature signal. In some embodiments, temperature sensing unit 120 may be implemented as a positive temperature coefficient (PTC) thermistor, a negative temperature coefficient (NTC) thermistor, a temperature sensing chip, or any other suitable temperature sensing element.

[0017] The processing unit 130 is coupled to the battery unit 110 and the temperature sensing unit 120. In some embodiments, the processing unit 130 may be a system on a chip (SoC), a central processing unit (CPU), a microcontroller unit (MCU), an application-specific integrated circuit (ASIC), an application processor (AP), or a digital signal processor (DSP), etc., but the embodiments of the present invention are not limited thereto.

[0018] A discharge switch 140 is coupled to battery cell 110 and processing unit 130. Processing unit 130 controls discharge switch 140 to enable smart battery device 100 to enter a discharge mode, for example, to supply electrical energy from battery cell 100 to a powered device. A charging switch 150 is coupled to processing unit 130 and the positive terminal BATT+ of smart battery device 100. Processing unit 130 controls charging switch 150 to enable smart battery device 100 to enter a charging mode, for example, to charge battery cell 110 using charging current provided by an external power source (not shown). In some embodiments, discharge switch 140 and charging switch 150 can be implemented using field-effect transistors (FETs), but the embodiments of the present invention are not limited thereto.

[0019] In this embodiment, the processing unit 130 can detect the presence of an external power source. When the processing unit 130 detects an external power source, it indicates that the smart battery device 100 can enter a charging mode, allowing the processing unit 130 to control the charging switch 150 to charge the battery unit 110. Then, in a charging mode, the processing unit 130 can receive a temperature signal and obtain the charge level of the battery unit 110, set the full charge capacity based on the temperature signal, and generate an indicator flag when the battery unit 110 reaches its full charge capacity. This indicator flag indicates that the battery unit is fully charged. In other words, the processing unit 130 can set different full charge capacities for the battery unit 110 based on different temperatures. This effectively increases battery life and provides battery safety.

[0020] Furthermore, after receiving the temperature signal, the processing unit 130 can determine whether the temperature of the temperature signal is lower than a first preset temperature. In this embodiment, the first preset temperature is, for example, 0 degrees Celsius, but the embodiments of the present invention are not limited thereto.

[0021] When the temperature signal is lower than a first preset temperature, it indicates that the smart battery device 100 is at a relatively cold temperature. To avoid affecting the lifespan or performance of the battery cell 110 by charging it at this temperature, the processing unit 130 controls the smart battery device 100 to enter a protection mode. For example, the processing unit 130 can control the charging switch 150 to turn off, thereby disabling the function of charging the battery cell 110.

[0022] When the temperature of the temperature signal is not lower than the first preset temperature, the processing unit 130 can determine whether the temperature of the temperature signal is lower than the second preset temperature. In this embodiment, the second preset temperature is, for example, greater than the first preset temperature, and the second preset temperature is, for example, 25 degrees Celsius, but the embodiments of the present invention are not limited thereto.

[0023] When the temperature signal is lower than a second preset temperature, for example, between 0 and 25 degrees Celsius, it indicates that the smart battery device 100 is at a relatively normal temperature. Next, the processing unit 130 can set the full charge capacity to a first preset value and generate an indicator when the battery cell 110's charge reaches the first preset value. In this embodiment, the first preset value is, for example, 100%, but the embodiments of the present invention are not limited to this. That is, when the temperature is between 0 and 25 degrees Celsius and the battery cell 110's charge reaches the first preset value, the processing unit 130 generates an indicator, for example, a high logic level "1", to indicate that the battery cell 110 is fully charged (e.g., 100%). Then, the high logic level "1" indicator can be provided to the powered device, allowing the powered device to display that the battery cell 110 is fully charged (e.g., 100%).

[0024] When the temperature of the temperature signal is not lower than the second preset temperature, the processing unit 130 can determine whether the temperature of the temperature signal is lower than the third preset temperature. In this embodiment, the third preset temperature is, for example, greater than the second preset temperature, and the third preset temperature is, for example, 45 degrees Celsius, but the embodiments of the present invention are not limited thereto.

[0025] When the temperature signal is lower than a third preset temperature, for example, between 25 and 45 degrees Celsius, it indicates that the smart battery device 100 is at a relatively high temperature. Next, the processing unit 130 can set the full charge capacity to a second preset value and generate an indicator when the battery cell 110's charge reaches the second preset value. In this embodiment, the second preset value is, for example, less than the first preset value, and the second preset value is, for example, 95%, but the embodiments of the present invention are not limited to this. That is, when the temperature is between 25 and 45 degrees Celsius and the battery cell 110's charge reaches the second preset value (e.g., 95%), the processing unit 130 generates, for example, a high logic level "1" indicator to indicate that the battery cell 110 is fully charged (e.g., 100%). Then, the high logic level "1" indicator can be provided to the powered device, allowing the powered device to display that the battery cell 110 is fully charged (e.g., 100%).

[0026] When the temperature of the temperature signal is not lower than the third preset temperature, the processing unit 130 can determine whether the temperature of the temperature signal is lower than the fourth preset temperature. In this embodiment, the fourth preset temperature is, for example, greater than the third preset temperature, and the fourth preset temperature is, for example, 60 degrees Celsius, but the embodiments of the present invention are not limited thereto.

[0027] When the temperature signal is lower than a fourth preset temperature, for example, between 45 and 60 degrees Celsius, it indicates that the smart battery device 100 is at a higher temperature. Next, the processing unit 130 can set the full charge capacity to a third preset value and generate an indicator when the battery cell 110's charge reaches the third preset value. In this embodiment, the third preset value is, for example, less than a second preset value, and the third preset value is, for example, 90%, but the embodiments of the present invention are not limited to this. That is, when the temperature is between 45 and 60 degrees Celsius and the battery cell 110's charge reaches the third preset value (e.g., 90%), the processing unit 130 generates, for example, a high logic level "1" indicator to indicate that the battery cell 110 is fully charged (e.g., 100%). Then, the high logic level "1" indicator can be provided to the powered device, allowing the powered device to display that the battery cell 110 is fully charged (e.g., 100%).

[0028] When the temperature signal is not lower than the fourth preset temperature, for example, when the temperature is greater than 60 degrees Celsius, it indicates that the smart battery device 100 is at an excessively high temperature. To avoid affecting the lifespan or performance of the battery cell 110 by charging it at this temperature, the processing unit 130 controls the smart battery device 100 to enter a protection mode. For example, the processing unit 130 can control the charging switch 150 to turn off, thereby disabling the function of charging the battery cell 110.

[0029] In the foregoing embodiment, after the processing unit 130 generates an indication flag, such as a high logic level "1", when the processing unit 130 detects that the charge level of the battery unit 110 is not at the fully charged state (e.g., 100%, 95%, or 90%) corresponding to the indication flag, the processing unit 130 clears the indication flag and provides the current charge level of the battery unit 110 to the powered device, so that the powered device displays the current charge level of the battery unit 110.

[0030] In addition, the smart battery device 100 in this embodiment also includes a current sensing unit 160. The current sensing unit 160 is coupled to the battery unit 110, the processing unit 130 and the negative terminal BATT- of the smart battery device 100. The current sensing unit 160 can sense the discharge current of the battery unit 110.

[0031] When the processing unit 130 detects the absence of external power, it indicates that the smart battery device 100 can enter a discharge mode, allowing the processing unit 130 to control the discharge switch 140 to discharge the battery cell 110. Then, in discharge mode, the processing unit 130 receives a temperature signal and a discharge current, and generates an adjustment instruction based on the temperature signal or the charge / discharge rate of the discharge current. This adjustment instruction instructs the powered device to adjust its operation. The processing unit 130 then transmits the adjustment instruction to the powered device via the transmission interface 131. In some embodiments, the transmission interface 131 is, for example, a system management bus (SMbus). That is, the processing unit 130 can provide different adjustment instructions to the powered device based on different temperatures or different charge / discharge rates of the discharge current, enabling the powered device to adjust the power consumption of its internal components (e.g., adjusting the frequency of the powered device's processing unit (e.g., CPU)). This effectively increases battery life and provides battery safety.

[0032] Furthermore, after receiving the temperature signal, the processing unit 130 can determine whether the temperature of the temperature signal is lower than a first preset temperature. In this embodiment, the first preset temperature is, for example, -20 degrees Celsius, but the embodiments of the present invention are not limited thereto.

[0033] When the temperature signal is lower than a first preset temperature, it indicates that the smart battery device 100 is at an excessively cold temperature. To prevent the battery cell 110 from discharging at this temperature and affecting its lifespan or performance, the processing unit 130 controls the smart battery device 100 to enter a protection mode. For example, the processing unit 130 can control the discharge switch 140 to open, thereby disabling the function of the battery cell 110 discharging.

[0034] When the temperature of the temperature signal is not lower than the first preset temperature, the processing unit 130 can determine whether the temperature of the temperature signal is lower than the second preset temperature. In this embodiment, the second preset temperature is, for example, greater than the first preset temperature, and the second preset temperature is, for example, 45 degrees Celsius, but the embodiments of the present invention are not limited thereto.

[0035] When the temperature signal is lower than the second preset temperature, for example, between -20 degrees Celsius and 45 degrees Celsius, it indicates that the smart battery device 100 is at a relatively normal temperature, and the processing unit 130 does not generate an adjustment instruction. That is, the processing unit 130 will not generate an adjustment instruction to the powered device, and the powered device will not adjust its operation and will operate normally. Subsequently, the processing unit 130 can continuously monitor the temperature signal to perform subsequent operations, such as controlling the smart battery device 100 to enter a protection mode or to prevent the generation of adjustment signals.

[0036] When the temperature of the temperature signal is not lower than the second preset temperature, the processing unit 130 can determine whether the temperature of the temperature signal is lower than the third preset temperature. In this embodiment, the third preset temperature is, for example, greater than the second preset temperature, and the third preset temperature is, for example, 50 degrees Celsius, but the embodiments of the present invention are not limited thereto.

[0037] When the temperature signal is lower than a third preset temperature, for example, between 45 and 50 degrees Celsius, it indicates that the smart battery device 100 is at a slightly higher temperature. Next, the processing unit 130 generates an adjustment instruction with a first adjustment value. In this embodiment, the first adjustment value is, for example, a 25% frequency reduction, but the embodiments of the present invention are not limited to this. That is, when the temperature is between 45 and 50 degrees Celsius, the processing unit 130 generates, for example, a 25% frequency reduction adjustment instruction to the powered device, so that the powered device can reduce the frequency of its processing device by 25% according to the 25% frequency reduction adjustment instruction. Then, the processing unit 130 can continuously monitor the temperature signal to perform subsequent operations, such as not generating an adjustment signal or generating an adjustment instruction with the first adjustment value.

[0038] When the temperature of the temperature signal is not lower than the third preset temperature, the processing unit 130 can determine whether the temperature of the temperature signal is lower than the fourth preset temperature. In this embodiment, the fourth preset temperature is, for example, greater than the third preset temperature, and the fourth preset temperature is, for example, 55 degrees Celsius, but the embodiments of the present invention are not limited thereto.

[0039] When the temperature signal is lower than a fourth preset temperature, for example, between 50 and 55 degrees Celsius, it indicates that the smart battery device 100 is at a relatively high temperature. Next, the processing unit 130 generates an adjustment instruction with a second adjustment value. In this embodiment, the first adjustment value is, for example, a 50% frequency reduction, but this embodiment is not limited to this. That is, when the temperature is between 50 and 55 degrees Celsius, the processing unit 130 generates, for example, a 50% frequency reduction adjustment instruction to the powered device, so that the powered device can reduce the frequency of its processing device by 50% according to the 50% frequency reduction adjustment instruction. Then, the processing unit 130 can continuously monitor the temperature signal to generate an adjustment instruction with the first adjustment value or an adjustment instruction with the second adjustment value.

[0040] When the temperature of the temperature signal is not lower than the fourth preset temperature, the processing unit 130 can determine whether the temperature of the temperature signal is lower than the fifth preset temperature. In this embodiment, the fifth preset temperature is, for example, greater than the fourth preset temperature, and the fifth preset temperature is, for example, 60 degrees Celsius, but the embodiments of the present invention are not limited thereto.

[0041] When the temperature signal is lower than a fifth preset temperature, for example, between 55 and 60 degrees Celsius, it indicates that the smart battery device 100 is at a high temperature. Next, the processing unit 130 generates an adjustment instruction with a third adjustment value. In this embodiment, the first adjustment value is, for example, a 75% frequency reduction, but this embodiment is not limited to this. That is, when the temperature is between 55 and 60 degrees Celsius, the processing unit 130 generates, for example, a 75% frequency reduction adjustment instruction to the powered device, so that the powered device can reduce the frequency of its processing device by 75% according to the 75% frequency reduction adjustment instruction. Next, the processing unit 130 can continuously monitor the temperature signal to generate an adjustment instruction with a second adjustment value or an adjustment instruction with a third adjustment value.

[0042] When the temperature signal is not lower than the fifth preset temperature, for example, if the temperature is greater than 60 degrees Celsius, it indicates that the smart battery device 100 is at an excessively high temperature. Next, the processing unit 130 generates an adjustment instruction with a shutdown indication. That is, when the temperature is greater than 60 degrees Celsius, the processing unit 130 generates an adjustment instruction with a shutdown indication to the powered device, causing the powered device to shut down to prevent the battery cell 110 from discharging at this temperature, which could affect the battery cell 110's lifespan or performance. In this way, by generating an adjustment instruction through the processing unit 130, the processing device of the powered device is able to reduce its frequency or the powered device is able to shut down to prevent the battery cell 110 from over-discharging, effectively increasing the battery cell 110's lifespan, performance, and safety.

[0043] Furthermore, after receiving the discharge current, the processing unit 130 can determine whether the charge / discharge rate of the discharge current is less than a first preset charge / discharge rate. In this embodiment, the first preset charge / discharge rate is, for example, 1C, but the embodiments of the present invention are not limited thereto.

[0044] When the discharge current's charge / discharge rate is less than the first preset charge / discharge rate, it indicates that the discharge current's charge / discharge rate is normal, and the processing unit 130 does not generate an adjustment instruction. In other words, the processing unit 130 will not generate an adjustment instruction for the powered device, and the powered device will not adjust its operation and will operate normally. Subsequently, the processing unit 130 can continuously monitor the discharge current to perform subsequent operations, such as when the processing unit 130 does not generate an adjustment instruction.

[0045] When the charge / discharge rate of the discharge current is not less than the first preset charge / discharge rate, the processing unit 130 can determine whether the charge / discharge rate of the discharge current is less than the second preset charge / discharge rate. In this embodiment, the second preset charge / discharge rate is, for example, greater than the first preset charge / discharge rate, and the second preset charge / discharge rate is, for example, 1.2C, but the embodiments of the present invention are not limited thereto.

[0046] When the discharge current's charge / discharge rate is less than a second preset charge / discharge rate, for example, when the discharge current's charge / discharge rate is between 1C and 1.2C, it indicates that the discharge current's charge / discharge rate is slightly high. Next, the processing unit 130 generates an adjustment instruction with a first adjustment value. In this embodiment, the first adjustment value is, for example, a 50% frequency reduction, but the embodiments of the present invention are not limited to this. That is, when the discharge current's charge / discharge rate is between 1C and 1.2C, the processing unit 130 generates, for example, a 50% frequency reduction adjustment instruction to the powered device, so that the powered device can reduce the frequency of its processing device by 50% according to the 50% frequency reduction adjustment instruction. Then, the processing unit 130 can continuously monitor the discharge current to perform subsequent operations, such as not generating an adjustment signal or generating an adjustment instruction with the first adjustment value.

[0047] When the charge / discharge rate of the discharge current is not less than the second preset charge / discharge rate, the processing unit 130 can determine whether the charge / discharge rate of the discharge current is less than the third preset charge / discharge rate. In this embodiment, the third preset charge / discharge rate is, for example, greater than the second preset charge / discharge rate, and the third preset charge / discharge rate is, for example, 1.4C, but the embodiments of the present invention are not limited thereto.

[0048] When the discharge current's charge / discharge rate is less than a third preset charge / discharge rate, for example, when the discharge current's charge / discharge rate is between 1.2C and 1.4C, it indicates that the discharge current's charge / discharge rate is too high. Next, the processing unit 130 generates an adjustment instruction with a second adjustment value. In this embodiment, the second adjustment value is, for example, greater than the first adjustment value, and the second adjustment value is, for example, a 75% frequency reduction, but this embodiment is not limited to this. That is, when the discharge current's charge / discharge rate is between 1.2C and 1.4C, the processing unit 130 generates, for example, a 75% frequency reduction adjustment instruction for the powered device, so that the powered device can reduce the frequency of its processing device by 70% according to the 75% frequency reduction adjustment instruction. Next, the processing unit 130 can continuously monitor the discharge current to perform subsequent operations, such as generating an adjustment instruction with a first adjustment value or generating an adjustment instruction with a second adjustment value.

[0049] When the charge / discharge rate of the discharge current is not less than a third preset charge / discharge rate, the processing unit 130 can determine whether the charge / discharge rate of the discharge current is less than a fourth preset charge / discharge rate. In this embodiment, the fourth preset charge / discharge rate is, for example, greater than the third preset charge / discharge rate, and the fourth preset charge / discharge rate is, for example, 1.5C, but the embodiments of the present invention are not limited thereto.

[0050] When the discharge current's charge / discharge rate is less than a fourth preset charge / discharge rate, for example, when the discharge current's charge / discharge rate is between 1.4C and 1.5C, it indicates that the discharge current's charge / discharge rate is high. Next, the processing unit 130 generates an adjustment instruction with a limitation indication. That is, when the discharge current's charge / discharge rate is between 1.4C and 1.5C, the processing unit 130 generates an adjustment instruction with a limitation indication to the powered device, allowing the powered device to limit the frequency of its processing device according to the limitation indication. For example, the frequency of the powered device's processing device can be limited to, for example, a 75% reduction. Next, the processing unit 130 can continuously monitor the discharge current to perform subsequent operations, such as generating an adjustment instruction with a second adjustment value or generating an adjustment instruction with a limitation indication.

[0051] When the discharge current's charge / discharge rate is not less than the fourth preset charge / discharge rate, for example, when the discharge current's charge / discharge rate is greater than 1.5C, it indicates that the discharge current's charge / discharge rate is too high. Next, the processing unit 130 generates a shutdown indication adjustment instruction. That is, when the discharge current's charge / discharge rate is greater than 1.5C, the processing unit 130 generates a shutdown indication adjustment instruction for the powered device, enabling the powered device to shut down according to the shutdown indication adjustment instruction. In this way, by generating an adjustment instruction through the processing unit 130, the powered device's processing unit can reduce its frequency or shut down the powered device to avoid over-discharging of the battery cell 110, effectively increasing the battery cell 110's lifespan, performance, and safety.

[0052] Based on the above description, this embodiment of the invention provides an operation method for a smart battery device. Figure 2 This is a flowchart of an operation method of a smart battery device according to an embodiment of the present invention. In step S202, the ambient temperature is sensed to generate a temperature signal. In step S204, in charging mode, the temperature signal is received and the battery cell charge level is obtained. In step S206, the charge capacity is set according to the temperature signal, and when the battery cell charge level reaches the charge capacity, an indicator mark is generated, wherein the indicator mark is used to indicate that the battery cell is fully charged. In step S208, the discharge current of the battery cell is sensed. In step S210, in discharge mode, the temperature signal and discharge current are received. In step S212, an adjustment instruction is generated according to the temperature signal or discharge current, wherein the adjustment instruction is used to instruct the powered device to adjust an operation.

[0053] Figure 3 for Figure 2 The detailed flowchart of step S206 is as follows. In step S302, it is determined whether the temperature of the temperature signal is lower than the first preset temperature. When the temperature of the temperature signal is lower than the first preset temperature, the process proceeds to step S304, controlling the intelligent battery device to enter the protection mode.

When the temperature signal is lower than the second preset temperature, proceed to step S308 to set the full charge capacity to the first preset value and generate an indicator mark when the battery cell's charge reaches the first preset value.

[0055] If the temperature signal is not lower than the second preset temperature, proceed to step S310 to determine if the temperature signal is lower than the third preset temperature. If the temperature signal is lower than the third preset temperature, proceed to step S312 to set the full charge capacity to the second preset value and generate an indicator when the battery cell's charge reaches the second preset value. If the temperature signal is not lower than the third preset temperature, proceed to step S314 to determine if the temperature signal is lower than the fourth preset temperature.

[0056] When the temperature signal is lower than the fourth preset temperature, proceed to step S316, set the full charge capacity to the third preset value, and generate an indicator mark when the battery cell's charge reaches the third preset value. When the temperature signal is not lower than the third preset temperature, proceed to step S318, controlling the smart battery device to enter protection mode. In this embodiment, the second preset temperature is greater than the first preset temperature, the third preset temperature is greater than the second preset temperature, the fourth preset temperature is greater than the third preset temperature, the second preset value is less than the first preset value, and the third preset value is greater than the second preset value.

[0057] Figure 4 for Figure 2 The detailed flowchart of step S212 is as follows: In step S402, it is determined whether the temperature of the temperature signal is lower than a first preset temperature. When the temperature of the temperature signal is lower than the first preset temperature, the process proceeds to step S404, controlling the intelligent battery device to enter protection mode. When the temperature of the temperature signal is not lower than the first preset temperature, the process proceeds to step S406, where it is determined whether the temperature of the temperature signal is lower than a second preset temperature.

[0058] When the temperature signal is lower than the second preset temperature, proceed to step S408 without generating an adjustment instruction. After completing step S408, you can return to step S402 to perform subsequent operations.

[0059] If the temperature signal is not lower than the second preset temperature, proceed to step S410 to determine if the temperature signal is lower than the third preset temperature. If the temperature signal is lower than the third preset temperature, proceed to step S412 to generate an adjustment instruction with a first adjustment value. After executing step S412, return to step S406 to perform subsequent operations.

[0060] If the temperature signal is not lower than the third preset temperature, proceed to step S414 to determine if the temperature signal is lower than the fourth preset temperature. If the temperature signal is lower than the fourth preset temperature, proceed to step S416 to generate an adjustment instruction with a second adjustment value. After executing step S416, return to step S410 to perform subsequent operations.

[0061] If the temperature signal is not lower than the fourth preset temperature, proceed to step S418 to determine if the temperature signal is lower than the fifth preset temperature. If the temperature signal is lower than the fifth preset temperature, proceed to step S420 to generate an adjustment instruction with a third adjustment value. After executing step S420, return to step S414 to perform subsequent operations.

[0062] When the temperature signal is not lower than the fifth preset temperature, proceed to step S422 to generate an adjustment instruction with a power-off indication. In this embodiment, the second preset temperature is greater than the first preset temperature, the third preset temperature is greater than the second preset temperature, the fourth preset temperature is less than the third preset temperature, the fifth preset temperature is less than the fourth preset temperature, the second adjustment value is greater than the first adjustment value, and the third adjustment value is greater than the second adjustment value.

[0063] Figure 5 for Figure 2 Another detailed flowchart of step S212.
