The core of the application is to provide an electronic product, a battery discharge protection method, a battery discharge protection device and a battery discharge protection medium.
In order that those skilled in the art will better understand the disclosure, the following detailed description will be given with reference to the accompanying drawings.
It should be noted that the electronic product mentioned in the present invention may be a head-mounted device or a wrist band device, such as a wireless earphone, an electronic glasses, an electronic hearing aid, and other products containing a battery. It is understood that the types of batteries mentioned in the present application can be varied, for example, the most common lithium batteries, and of course, besides lithium batteries, nickel cadmium batteries, nickel hydrogen batteries, etc., and hereinafter, the battery is mainly described as a lithium battery. In addition, the battery discharge protection method of the electronic product mentioned in the present application may be implemented by an MCU (micro control unit) or other types of control devices in the electronic product, without affecting the implementation of the technical solution.
Fig. 1 is a flowchart of a battery discharge protection method of an electronic product according to an embodiment of the present disclosure.
As shown in fig. 1, the method includes:
s10: and acquiring the corresponding relation between each dynamic parameter of the battery and each discharge protection voltage value in advance.
In particular implementations, the electronic product may include a storage device, a control device, and the like, for different types, in addition to a battery. Wherein, the above corresponding relation can be stored by a storage device. It is understood that the type of the dynamic parameter in the present embodiment is not limited, and is mainly a parameter closely related to the discharge protection voltage value, for example, a temperature parameter and/or a current parameter (discharge current). Table 1 is a table of correspondence between discharge protection voltage values and temperature parameters and current parameters, and table 1 shows the correspondence between temperature parameters and current parameters and discharge protection voltage values, and specifically, the data in table 1 can be obtained through experimental data.
TABLE 1
It should be noted that, in the specific implementation, since there are numerous possible values of the current dynamic parameter of the battery within a certain range, the discrete points in table 1 may be subjected to linear fitting to obtain a corresponding curve. Fig. 2 is a graph illustrating a relationship between a discharge protection voltage and a temperature parameter and a current parameter according to an embodiment of the present disclosure. As shown in fig. 2, curves of the current parameter and the discharge protection voltage were obtained for different temperature parameters, wherein the horizontal axis represents the current value in mA and the vertical axis represents the voltage value in mV.
In a concrete implementation, the correspondence may be recorded as discrete points in table 1 or as curves in fig. 2, and this embodiment is not limited thereto.
It is understood that the dynamic parameters given in table 1 include: the temperature parameter and the current parameter may be the case, and in other embodiments, may be the temperature parameter alone or the current parameter alone.
S11: and reading the current target dynamic parameters of the battery.
Fig. 3 is a structural diagram of an electronic product according to an embodiment of the present application. As shown in fig. 3, the temperature acquisition module 1, the current acquisition module 2, the voltage acquisition module 3 and the power management module 4 are all electrically connected with the MCU5, wherein the temperature acquisition module 1 is used for acquiring temperature parameters of the battery, the current acquisition module 2 is used for acquiring current parameters of the battery, the voltage acquisition module 3 is used for acquiring voltage parameters of the battery, and the power management module 4 is used for cutting off the connection between the battery and the power consumption device according to an instruction of the MCU, so as to shut down the electronic product.
In this step, taking MCU as an example, the target dynamic parameters can be read in real time, or read according to a certain period.
S12: and determining a target discharge protection voltage value corresponding to the target dynamic parameter according to the corresponding relation.
Since the corresponding relationship is obtained in advance, the target discharge protection voltage value corresponding to the target dynamic parameter can be determined according to the corresponding relationship (the target discharge protection voltage value is one of the discharge protection voltage values, and is to be distinguished from the remaining discharge protection voltage values). It can be seen from fig. 2 that the temperature parameters range from 10 ℃ to 70 ℃ and the interval is 20 ℃, so when the target temperature parameter in the target dynamic parameter is not 10 ℃, 30 ℃, 50 ℃ or 70 ℃, the curve corresponding to the closest temperature value can be selected to determine the target discharge protection voltage value, or the average value of two discharge protection voltage values determined by the curves corresponding to two adjacent temperature values can be selected as the target discharge protection voltage value. For example, the target temperature parameter and the target current parameter in the target dynamic parameter are respectively 15 ℃ and 50mA, and when the target discharge protection voltage value is determined, which curve to select may be determined first, for example, a curve of 10 ℃ is selected, and then the target discharge protection voltage value may be uniquely determined by the current value (50mA) of the horizontal axis; or two curves of 10 ℃ and 30 ℃ are selected, then two target discharge protection voltage values are determined through the current value (50mA) of the horizontal axis, wherein the two target discharge protection voltage values are 2840mV and 2850mV respectively, and the average value of the 2845mV of the two target discharge protection voltage values is taken as the target discharge protection voltage value.
It can be seen that as the target dynamic parameter changes, for example, the battery temperature increases and the discharge current decreases, the target discharge protection voltage value changes, that is, the discharge protection voltage value of the battery obtained in the above manner is not fixed but dynamically changes.
The above description is given by taking an example that the dynamic parameter includes the temperature parameter and the current parameter, in other embodiments, if the dynamic parameter includes only the temperature parameter, only the temperature parameter needs to be considered, and the current parameter does not need to be considered, and similarly, if the dynamic parameter includes only the current parameter, only the current parameter needs to be considered, and the temperature parameter does not need to be considered. In addition, compared with the single parameter, the multiple parameters are considered in combination, the determined discharge protection voltage values are more reasonable, and the utilization rate of the battery is further improved.
S13: and judging whether the actual voltage value of the battery is reduced to the target discharge protection voltage value, if so, entering S14, and if not, returning to S11.
S14: and controlling the battery to stop outputting the electric energy.
In S12, a target discharge protection voltage value corresponding to the current target dynamic parameter of the battery is calculated, as shown in fig. 3, the MCU reads the actual voltage value collected by the voltage collection module, and when the voltage value decreases to the target discharge protection voltage value, sends an instruction to the power management module to control the battery to stop outputting electric energy, and the electronic product is shut down.
In the battery discharge protection method provided by this embodiment, since the corresponding relationship between each dynamic parameter of the battery and each discharge protection voltage value is obtained in advance, the target discharge protection voltage value corresponding to the target dynamic parameter can be determined according to the corresponding relationship when the current target dynamic parameter of the battery is read, and since the target dynamic parameter is the current parameter of the battery, the target discharge protection voltage value determined through the corresponding relationship is also a parameter suitable for the current of the battery, and when the actual voltage value of the battery decreases to the target discharge protection voltage value, the battery is controlled to stop outputting electric energy. By adopting the technical scheme, the discharge protection voltage value of the battery is not a fixed value any more, but is determined according to the dynamic parameters, so that the defects caused by the fixed value can be overcome, the energy of the battery can be fully utilized, the cruising ability of a battery product is improved, and the user experience is improved.
Fig. 4 is a flowchart of another method for protecting battery discharge of an electronic product according to an embodiment of the present disclosure. On the basis of the above embodiment, before S13, the method further includes:
s20: acquiring the running state of an electronic product;
s21: judging whether the running state represents that the electronic product is not in the working mode, if so, entering S13, and if not, entering S22;
s22: judging whether the actual voltage value of the battery is reduced to a low-power reminding voltage value or not, if so, entering S23, and if not, returning to S11;
s23: outputs the alert signal, and proceeds to S13.
It should be noted that the low power reminding voltage value is greater than the target discharge protection voltage value, in other words, if the electronic product is not in the working mode, the electronic product is shut down when the actual voltage value decreases to the target discharge protection voltage value, and if the electronic product is in the working mode, the reminding is performed before the actual voltage value decreases to the target discharge protection voltage value, that is, the reminding is performed before the electronic product is shut down. Obviously, if the electronic product is not in the working mode, the user is not greatly influenced even if the electronic product is shut down, but if the electronic product is in the working mode, the user is indicated to be in use, and if the electronic product is shut down at the moment, the task is interrupted, so that the use of the user is influenced. Since the low-power reminding voltage value is greater than the target discharge protection voltage value, the reminding signal is generated before shutdown, so that for a user, the user can know the low power of the battery in advance, and further can adopt operations such as charging or stopping a working mode and the like.
It should be understood that, in this embodiment, the manner of outputting the alert signal is not limited, and if the bluetooth headset includes a speaker and a vibration component, the alert signal for controlling the speaker to turn on may be output, or the alert signal for controlling the vibration component to turn on may be output, or the alert signal for controlling the signal lamp to turn on may be output.
Further, the purpose of the low power alert voltage value is to alert before the voltage of the voltage drops to the target discharge protection voltage value, so the low power alert voltage value may be set to a fixed value, but the same principle as the discharge protection voltage value, if set to a fixed value, the alert is not reasonable enough, so as a preferred embodiment, the low power alert voltage value is proportional to the target discharge protection voltage value, i.e., V1 ═ n × V0, n > 1, V1 is the low power alert voltage value, and V0 is the target discharge protection voltage value. It is understood that the target discharging protection voltage value is determined by the current dynamic parameters of the battery, so that the low-power reminding voltage value is set to be in direct proportion to the target discharging protection voltage value, and the low-power reminding voltage value can change along with the change of the current dynamic parameters of the battery.
On the basis of the above embodiment, the electronic product is a wireless headset, and the operation state includes an unconnected state, a broadcast state, a connected and non-working state, and a connected and working state;
the unconnected state represents that the electronic product is not in the working mode, and the broadcast state, the connected and non-working state and the connected and working state represent that the electronic product is in the working mode.
The wireless headset in this embodiment may be a bluetooth headset, and the wireless headset determines whether to perform low power reminder or directly controls the electronic product to shut down when the voltage value is lower than the target protection voltage value according to different operating states of the wireless headset. Because the wireless earphone is not in the working mode when not connected, the wireless earphone is directly turned off without great influence on the user, and therefore low-power reminding is not needed. Since the wireless headset is in the broadcasting state, the connected and non-operating state or the connected and operating state, it is characterized that the wireless headset is in the operating mode, and since the wireless headset is in the operating mode, the wireless headset is directly turned off, which may cause a large impact on the user, and therefore a low power reminder is required. For example, when a user is using a wireless headset to make a call, the wireless headset is necessarily in a connected and working state, if the actual voltage value of the battery is reduced to the target discharge protection voltage value, the battery is controlled to stop outputting electric energy, the user is powered off when the user does not have time to charge or finish the call, and if the user performs low-power reminding, the user can have a sufficient time to charge the headset or finish the call in advance.
Further, outputting the reminding signal specifically includes: and outputting a corresponding reminding signal according to the running state.
Because the low-power reminding is required, different running states are suitable for different reminding modes, and therefore the experience of a user can be improved. For example, in one embodiment, when the wireless headset is in a broadcast state or a connected non-operational state, a voice broadcast is used: "the electric quantity is low please charge", when wireless headset was in connected and operating condition, adopted voice broadcast: a "bite" whereby the user is prevented from being disturbed in his conversation or a warning signal for controlling the opening of the vibrating member is outputted.
In order to make the technical solution proposed in the present application more clear to those skilled in the art, a specific application scenario of the bluetooth headset is described by taking the bluetooth headset as an example. The user opens bluetooth headset to establish with the cell-phone and be connected, converse with another user through bluetooth headset, MCU reads the current temperature parameter of battery and current parameter in real time, and confirm the target discharge protection voltage value that target dynamic parameter corresponds according to the corresponding relation, when the actual voltage value of battery drops to low-power warning voltage value, adopt voice broadcast: the method comprises the steps that a warning signal is sent in a 'sting' mode, if a user does not finish a call, the temperature parameter and the current parameter of a battery dynamically change to generate a new target discharge protection voltage value, when the voltage value of the battery is reduced to the target discharge protection voltage value, an MCU sends an output stopping signal to a power management module, and after receiving the output stopping signal, the power management module controls the battery to stop supplying power, and the Bluetooth headset is turned off.
