Description

Technical Field

[0001] This invention relates to a battery life detector, and more particularly to a battery life detector for rapidly detecting battery life. Background Technology

[0002] A battery is a device that converts chemical energy into electrical energy. Its working principle is to use chemical reactions to generate electron flow between the positive and negative electrodes, thereby forming an electric current. Batteries provide power for electronic products, vehicles, instruments and equipment.

[0003] Batteries are broadly classified into two categories: disposable batteries and rechargeable batteries. Disposable batteries (also known as primary batteries or galvanic batteries) are batteries in which the internal chemical reaction cannot be reversed during the conversion of chemical energy into electrical energy. Therefore, they can only be used once and cannot be recharged or reused. Once the active materials inside the battery have completely reacted, the battery's power is depleted, and it can only be discarded or recycled. Common disposable batteries include carbon-zinc batteries, alkaline manganese batteries, lithium batteries, zinc batteries, zinc-air batteries, zinc-mercury batteries, mercury batteries, hydrogen-oxygen batteries, and magnesium-manganese batteries. Rechargeable batteries (also known as secondary batteries, secondary batteries, or storage batteries) can restore energy through recharging after being depleted. Their advantage is that they can be used multiple times after recharging. They can be fully charged and discharged more than 200 times or even up to 40,000 times. The output current load capacity of rechargeable batteries is higher than that of most disposable batteries. Common types of rechargeable batteries include lithium batteries, nickel-metal hydride batteries, and lead-acid batteries.

[0004] Batteries come in various shapes and sizes to meet the needs of different devices. Common battery shapes include cylindrical batteries, button batteries, square batteries, pouch batteries, and special-shaped batteries. Cylindrical batteries include 18650 batteries, 21700 batteries, AA (size 5 rechargeable batteries), and AAA (size 7 rechargeable batteries). The 18650 battery is the most common lithium-ion cylindrical battery, with a diameter of about 18 mm and a height of 65 mm. It is commonly used in laptops, power banks, power tools, and electric vehicles.

[0005] A battery detector is a tool specifically designed to test the state of a battery. Its functions typically include voltage testing, current testing, internal resistance testing, charge / discharge testing, battery capacity detection, temperature detection, automatic detection and classification, and safety detection. Among these, battery life is evaluated by using multiple parameters such as battery capacity detection, internal resistance testing, voltage stability testing, charge / discharge cycle count, and temperature anomaly detection.

[0006] However, conventional measurement methods can only provide comprehensive information about the battery's health status, thus helping to predict the battery's remaining lifespan and determine when the battery needs to be replaced. They cannot provide accurate battery lifespan, and conventional battery detectors cannot achieve the effect of quickly detecting battery lifespan based on the predicted remaining battery lifespan and the user's desired battery lifespan.

[0007] In view of the problems of the prior art, the present invention provides a battery life detector, which includes: a detection module, a specification control module, a demand control module, a calculation module and an output module, to solve the problems of the prior art in predicting the remaining life of the battery only through the battery health status when measuring battery life, and failing to provide accurate battery life, and failing to achieve the effect of quickly detecting battery life while predicting the remaining life of the battery. Summary of the Invention

[0008] One objective of this invention is to provide a battery life detector. First, a specification control module inputs specification data, and a demand control module inputs demand data. When a detection module detects the battery current and generates current data, a calculation module receives the current data, specification data, and demand data, and generates life data and calculation results based on these data. Finally, an output module generates an output signal based on the calculation results. This addresses the problem that conventional battery life measurements only predict the remaining battery life based on the battery's health status, failing to provide accurate battery life data, and also fails to achieve rapid battery life detection while predicting the remaining battery life.

[0009] To achieve the aforementioned objectives and effects, the present invention provides a battery life detector for detecting batteries.

The specification control module defaults to specification data, the demand control module defaults to demand data, the calculation module is electrically connected to the detection module, the specification control module, and the demand control module, and the output module is electrically connected to the second calculation module.

[0010] In one embodiment of the present invention, after the detection module detects the current of the battery and generates current data, the calculation module calculates the life data based on the specification data and the current data. When the life data is greater than the required data, the calculation module generates a calculation result, and the output module generates an output signal based on the calculation result.

[0011] In one embodiment of the present invention, the lifespan data is the remaining lifespan of the battery, and the calculation module calculates the lifespan data to satisfy the following equation:

[0012] A / B / 365.25 / 24 = C

[0013] Where A represents specifications, B represents current, and C represents lifespan.

[0014] In one embodiment of the present invention, the calculation module includes a first calculation unit and a second calculation unit. The first calculation unit receives and generates lifetime data based on current data and specification data, and the second calculation unit receives and generates calculation results based on lifetime data and demand data.

[0015] In one embodiment of the present invention, the battery life detector further includes a connection module for electrically connecting to the battery, the connection module being used to enable the detection module to detect the battery current through the connection module.

[0016] In one embodiment of the present invention, the output module is a light-emitting unit, and the output signal is light.

[0017] In one embodiment of the present invention, the output module is a speaker, and the output signal is sound.

[0021] In one embodiment of the present invention, the calculation module includes a fourth display unit, which displays a fourth screen based on the lifespan data.

[0022] In one embodiment of the present invention, it further includes a first control module and a second control module, the first control module being used to set specification data, the second control module being used to set requirement data, and the first control module and the second control module having knobs or buttons.

[0024] To provide a better understanding of the structural features and effects achieved by the present invention, preferred embodiments and detailed descriptions are provided below:

[0025] Conventional battery measurement methods can only provide comprehensive information about the battery's health status, thus helping to predict the battery's remaining lifespan and determine when the battery needs to be replaced. However, they cannot provide accurate battery lifespan information. Furthermore, conventional battery detectors cannot achieve the effect of quickly detecting battery lifespan based on the predicted remaining battery lifespan and the user's desired battery lifespan.

[0026] In view of the problems of the prior art described above, the present invention provides a battery life detector. First, a specification control module inputs specification data, and a demand control module inputs demand data. When the detection module detects the battery current and generates current data, the calculation module receives and generates life data and calculation results based on the current data, specification data, and demand data. The output module generates an output signal based on the calculation results. This solves the problems of conventional battery life measurement methods that only predict the remaining battery life based on the battery's health status and cannot provide accurate battery life, and also the inability to quickly detect battery life while predicting the remaining battery life.

[0027] Please see Figure 1A The figure shows a schematic diagram of an embodiment of the present invention. As shown in the figure, this embodiment is the first embodiment, which is a battery life detector used to detect a battery 3. The battery life detector 1 includes: a detection module 10, a specification control module 20, a demand control module 30, a calculation module 40 and an output module 50.

[0028] Continuing from the above, in this embodiment, the detection module 10 is electrically connected to the battery 3. The detection module 10 is used to detect a current 32 of the battery 3 and generate a current data 11. The current data 11 is a digital current value, for example, from 1 microampere to 100 microamperes, but is not limited thereto.

[0029] Continuing from the above, in this embodiment, the specification control module 20 pre-inputs a specification data 21, which is the factory specification of the battery 3, for example: 1 mAh to 20000 mAh, but is not limited thereto.

[0030] Continuing from the above, in this embodiment, the demand control module 30 pre-inputs a demand data 31, which is the battery life time required by the user, for example: 1 to 10 years, but not limited thereto.

[0031] Continuing from the above, in this embodiment, the calculation module 40 is electrically connected to the detection module 10, the specification control module 20 and the demand control module 30. The calculation module 40 is used to generate a lifetime data 41 and a calculation result 43. The lifetime data 41 is the remaining lifetime time of the battery 3.

[0032] Continuing from the above, in this embodiment, the output module 50 is electrically connected to the calculation module 40, and the output module 50 generates an output signal 51 based on the calculation result 43.

[0033] Continuing from the above, in another embodiment, the output module 50 is a light-emitting unit, and the output signal 51 is a light ray.

[0034] Continuing from the above, in another embodiment, the output module 50 is a speaker, and the output signal 51 is a sound.

[0035] Continuing from the above, please refer to Figure 1B The figure shows a signal step flowchart of an embodiment of the present invention. In this embodiment, the signal flow of the battery life detector 1 includes at least one of the following steps: S10: The specification control module 20 defaults to specification data 21, and the requirement control module 30 defaults to requirement data 31. S20: The detection module 10 detects the current 32 of the battery 3 and generates the current data 11; S30: The calculation module 40 calculates the lifetime data 41 based on the specification data 21 and the current data 11; S40: When the calculation module 40 compares the lifetime data 41 with the required data 31, the calculation module 40 generates the calculation result 43; and S50: The output module 50 then generates the output signal 51 based on the calculation result 43.

[0036] Following the above, in step S30 of this embodiment, the calculation module 40 calculates that the lifetime data 41 satisfies the following equation (Equation 1): A / B / 365.25 / 24 = C (Equation 1) Where A is the specification data 21, B is the current data 11, and C is the lifespan data 41.

[0037] Continuing from the above, in steps S40 and S50 of this embodiment, if the calculation module 40 finds that the lifetime data 41 is less than the required data 31, the calculation module 40 cannot generate the calculation result 43, and the output module 50 cannot generate the output signal 51 based on the calculation result 43.

[0038] The following explanation uses the following specifications as an example: 21 is 220 mA per hour, 11 is 4 μA, and 31 is a 5-year requirement.

[0039] Continuing from the above, in this embodiment, the specification control module 20 defaults to the specification data 21 of 220 mA per hour, and the demand control module 30 defaults to the demand data 31 of 5 years. When the detection module 10 detects the current 32 of the battery 3 and generates the current data 11 of 4 microamps, the calculation module 40 calculates the lifespan data 41 by using formula (a) based on the current data 11 of 4 microamps and the specification data 21 of 220 mA per hour. The lifespan data 41 is 6.3 years. The calculation module 40 compares the lifespan data 41 of 6.3 years with the demand data 51 of 5 years, and therefore the calculation module 40 generates the calculation result 43. The output module 50 generates the output signal 51 based on the calculation result 43.

[0040] In the above embodiments, the computing module 40 further includes a first computing unit 45 and a second computing unit 47, which will be described below:

[0041] Please see Figure 2A The figure shows a schematic diagram of another embodiment of the present invention. In another embodiment, the computing module 40 includes the first computing unit 45 and the second computing unit 47.

[0042] Continuing from the above, in another embodiment, the first calculation unit 45 receives and generates the lifetime data 41 based on the current data 11 and the specification data 21, and the second calculation unit 47 receives and generates the calculation result 43 based on the lifetime data 41 and the demand data 31.

[0043] In the above embodiments, the battery life detector 1 further includes a connection module 60, which will be described below:

[0044] Please see Figure 2B The figure shows a schematic diagram of another embodiment of the present invention. In another embodiment, the battery life detector 1 further includes the connection module 60.

[0045] Continuing from the above, in another embodiment, the connection module 60 is used to electrically connect the battery 3, so that the detection module 10 can detect the current 32 of the battery 3 through the connection module 60.

[0046] In the above embodiments, the battery life detector 1 does not display the current data 11, the specification data 21, the demand data 31, and the life data 41. Therefore, the present invention provides a display unit for displaying the current data 11, the specification data 21, the demand data 31, and the life data 41, which will be described below:

[0047] Please see Figure 2C The figure shows a schematic diagram of another embodiment of the present invention. In another embodiment, the detection module 10 includes a first display unit 13, which displays a first screen 131 based on the current data 11.

[0048] Continuing from the above, in another embodiment, the specification control module 20 includes a second display unit 23, which displays a second screen 231 according to the specification data 21.

[0049] Continuing from the above, in another embodiment, the demand control module 30 includes a third display unit 33, which displays a third screen 331 based on the demand data 31.

[0050] Continuing from the above, in another embodiment, the computing module 40 includes a fourth display unit 49, which displays a fourth screen 491 based on the lifetime data 41.

[0051] In the above embodiments, the specification data 21 and the requirement data 31 are not controlled by the control module. Therefore, the present invention provides a control module for controlling the specification data 21 and the requirement data 31, which will be described below:

[0052] Please see Figure 2D The figure shows a schematic diagram of another embodiment of the present invention. In another embodiment, the battery life detector 1 further includes a first control module 70, which is used to set the specification data 21. The first control module 70 is a knob or a button.

[0053] Continuing from the above, in another embodiment, the battery life detector 1 further includes a second control module 80, which is used to set the demand data 31. The second control module 80 is a knob or a button.

[0054] In summary, this invention provides a battery life detector. First, the specification control module defaults to specification data, and the demand control module defaults to demand data. When the detection module detects the battery current and generates current data, the calculation module receives and calculates life data based on the current data and specification data. When the calculation module compares the life data with the demand data, it generates a calculation result. The output module then generates an output signal based on the calculation result. This solves the problem that conventional battery life measurement methods only predict the remaining battery life based on the battery's health status, failing to provide accurate battery life prediction, and also fails to achieve rapid battery life detection while predicting the remaining battery life.
