In the correlation technique, in order to reduce the influence of battery protection board generate heat and terminal heat dissipation to NTC collection battery, adopt on the one hand to thicken the battery protection board and widen to this reduces the influence that the protection board generates heat and samples the NTC temperature. But widen the battery protection shield thickening, can improve the cost of protection shield, can crowd simultaneously and take up battery space for battery effective capacity descends. On the other hand, adopt to let walk on the battery protection shield and walk the position that the line kept away from the NTC and put to this reduces the protection shield and generates heat the influence to NTC temperature sampling. Let walk the line on the battery protection shield and keep away from the position that the NTC put, can suitably reduce the protection shield and generate heat the influence to NTC temperature sampling, but the terminal heat dissipation can not eliminate to the influence of NTC collection battery. Therefore, in order to overcome the problem that the current temperature of the battery acquired by the NTC in the related art cannot accurately reflect the temperature of the battery, the present disclosure provides a method for determining the temperature of the battery, which can accurately reflect the temperature of the battery.
The technical scheme of the exemplary embodiment of the present disclosure may be applied to an application scenario in which a battery of a terminal is temperature-collected and stored. In the exemplary embodiments described below, a terminal is sometimes also referred to as an intelligent terminal device, where the terminal may be a Mobile terminal, and may also be referred to as a User Equipment (UE), a Mobile Station (MS), and the like. A terminal is a device that provides voice and/or data connection to a user, or a chip disposed in the device, such as a handheld device, a vehicle-mounted device, etc. having a wireless connection function.

Fig. 1 is a flow chart illustrating a battery temperature determination method according to an exemplary embodiment, as shown in fig. 1, the battery temperature determination method including the following steps.
In step S11, the current temperature of the battery acquired by the NTC is acquired, and the charging current of the battery and the accumulated charging time period of the battery are acquired.
In an exemplary embodiment of the present disclosure, the NTC may be a device mounted in the battery for detecting the temperature of the battery. Further, the NTC may be an NTC mounted on the battery protection plate, and the temperature of the battery is periodically collected using the NTC. In the charging process of the battery, due to the influence of the heating of the battery protection board and the terminal heat dissipation condition, the current temperature of the battery collected by the NTC can be the temperature of the battery and the temperature of the battery protection board after the heating and the terminal heating are superposed. Therefore, in order to eliminate the deviation between the NTC collection temperature and the battery temperature, the deviation temperature of the NTC collection temperature needs to be compensated, and the compensation of the deviation temperature of the NTC collection temperature is the compensation temperature of the battery in the disclosure.
In the process of charging the terminal, the heating of the battery protection board and the heat dissipation condition of the terminal are related to the charging current and the charging duration. The compensated temperature of the battery may be determined based on the present charging current and the accumulated charging time. Therefore, in the present disclosure, the battery charging current and the accumulated charging time of the battery are obtained, and the compensation temperature of the battery is determined according to the charging current and the accumulated charging time.
In step S12, the current compensation temperature of the battery is determined based on the charging current and the accumulated charging time period.
In step S13, a target temperature of the battery is determined according to the current temperature of the battery collected by the NTC and the current compensation temperature of the battery.
In an exemplary embodiment of the present disclosure, since the NTC collects the temperature, a periodic collection manner is adopted. And then according to the current temperature of the battery acquired by the NTC at the current sampling time point, the charging current and the continuous charging time at the current sampling time point can be determined. And determining the compensation temperature of the battery at the current sampling time point according to the charging current and the continuous charging time at the current sampling time point, and further determining the target temperature of the battery at the current sampling time point according to the current temperature of the battery acquired by the NTC at the preset sampling time point and the compensation temperature of the battery at the current sampling time point.
In an exemplary embodiment of the disclosure, the current compensation temperature of the battery is determined through the acquired charging current of the battery and the accumulated charging time of the battery, and the target temperature of the battery is determined according to the acquired current temperature of the battery acquired by the NTC and the current compensation temperature of the battery, so that the accuracy of acquiring the target temperature of the battery is improved, and the charging safety of the battery and the charging stability of the battery are further ensured.
The present disclosure will be described below with reference to practical applications of a target temperature determination method of a battery according to the above-described embodiment.
The embodiments of the present disclosure first explain a determination process of the compensation temperature related to the above embodiments.
Fig. 2 is a flow chart illustrating a battery temperature determination method according to an exemplary embodiment, as shown in fig. 2, the battery temperature determination method including the following steps.
In step S21, the current temperature of the battery acquired by the NTC is acquired, and the battery charging current and the battery accumulated charging period are acquired.
In step S22, a first deviation temperature caused by the charging current to the current temperature of the NTC-collected battery is determined, and a second deviation temperature caused by the accumulated charging duration to the current temperature of the NTC-collected battery is determined, and a current compensation temperature of the battery is determined according to the first deviation temperature, the second deviation temperature, and a preset inherent temperature deviation.
In the disclosure, on the one hand, during the process of charging the terminal battery, especially during the process of charging with large current, the battery protection board itself generates large heat, during which the heat generation amount of the battery protection board is positively correlated with the charging current. On the other hand, due to different structural designs and heat dissipation conditions, the difference between the current temperature of the battery collected by the NTC and the current actual temperature of the battery varies with the charging duration.
The deviation of the charging current to the current temperature of the battery collected by the NTC can be determined by the influence coefficient of the charging current to the temperature deviation and the charging current. The deviation of the charging duration time to the current temperature of the battery collected by the NTC can be determined by the influence coefficient of the charging duration time to the temperature deviation and the charging duration time.
For convenience of description, the deviation temperature of the charging current to the current temperature of the NTC-collected battery is referred to as a first deviation temperature. The deviation temperature caused by the accumulated charging time period to the current temperature of the battery collected by the NTC is referred to as a second deviation temperature. The influence coefficient of the charging current on the temperature deviation is referred to as a first influence coefficient. The influence coefficient of the charging period on the temperature deviation is referred to as a second influence coefficient.
In an exemplary embodiment of the present disclosure, the first deviation temperature may be determined, for example, according to the following:
the product of the present charging current I and the coefficient of influence of the charging current on the temperature deviation (denoted α) is taken as the first deviation temperature. Namely: first deviation temperature ═ α I
In an exemplary embodiment of the present disclosure, the second deviation temperature may be determined according to the following manner:
the product of the accumulated charging time period t and the influence coefficient (denoted as β) of the charging time period on the temperature deviation is taken as the second deviation temperature. Namely: second deviation temperature ═ betat
The preset inherent temperature deviation can be the inherent deviation of the terminal and the battery of the terminal caused by the factors such as the design of a battery protection board and the whole terminal machine when the terminal leaves a factory, and is marked as delta.
The alpha can be formed by fitting actual test data through the actual influence of the charging current on the temperature deviation in the actual test of the battery temperature. Beta can also be formed by fitting test data through the actual influence of the charging time on the temperature deviation in the actual test of the battery temperature. Due to the individualization of the whole terminal design and the individualization of the battery adaptive to the terminal, when the alpha and the beta are fit through actual test data, the actual influence of the charging current and the charging time on the temperature deviation needs to be tested for each terminal. And fitting according to the test data of the actual influence of the charging current on the temperature deviation to obtain a constant value, and taking the constant value as the influence coefficient alpha of the charging current on the temperature deviation. And fitting according to the test data of the actual influence of the charging time length on the temperature deviation to obtain a constant value, and taking the constant value as the influence coefficient beta of the charging time length on the temperature deviation.
Summing the first deviation temperature, the second deviation temperature and the preset inherent temperature deviation to obtain the current compensation temperature (marked as T1) of the battery, namely:
T1＝αI+βt+δ
in step S23, a target temperature of the battery is determined according to the current temperature of the battery collected by the NTC and the compensated temperature of the battery.
In an exemplary embodiment of the present disclosure, when the target temperature of the battery is determined according to the current temperature of the battery collected by the NTC and the current compensation temperature of the battery, a difference operation may be performed between the current temperature of the battery collected by the NTC (denoted as T0) and the current compensation temperature of the battery to obtain the target temperature of the battery (denoted as T). Namely: T-T0-T1
In an exemplary embodiment of the present disclosure, the compensated temperature of the battery is obtained by determining a first deviation temperature caused by the charging current to the current temperature of the NTC-collected battery, determining a second deviation temperature caused by the accumulated charging duration to the current temperature of the NTC-collected battery, and obtaining the compensated temperature of the battery according to a preset inherent temperature deviation. According to the current temperature of the battery and the compensation temperature of the battery acquired by the NTC, the target temperature of the battery can be accurately determined. Under the condition of not increasing extra cost, the current compensation temperature of the battery compensates the error of NTC temperature sampling, and the safety and the charging stability of the battery in the charging process are ensured.
In the exemplary embodiment of the disclosure, after the target temperature of the battery is determined, the target temperature of the battery obtained each time may be stored, so that a plurality of programs that need to call the target temperature of the battery may all obtain the target temperature of the battery in time. When the target temperature of the battery is stored, in order to avoid the sudden jump of the target temperature of the battery when the charging current jumps, the target temperature of the battery can be smoothed, and the smoothed target temperature of the battery is stored, so that the accuracy of storing the target temperature of the battery is further improved.
The following embodiments of the present disclosure will be described with reference to a process of smoothing and storing a target temperature of a battery in practical use.
Fig. 3 is a flowchart illustrating a target temperature storage method of a battery according to an exemplary embodiment, and as shown in fig. 3, the target temperature storage method of the battery includes the following steps.
In step S31, target temperatures of the plurality of batteries determined within a preset time period before the current time are acquired.
In the present disclosure, in a scenario of fast charging based on a large current, or in a scenario of adjusting a charging current based on a current temperature of a battery acquired by NTC at a current time, the charging current may jump during charging of the battery. And the target temperature of the determined battery is also jumped based on the current temperature of the battery collected by the NTC and the compensation temperature of the battery at the moment of jumping of the charging current. Therefore, in order to avoid the stored target temperature of the battery from jumping too sharply, the target temperature of the battery needs to be smoothed before the target temperature of the battery is stored, and the smoothed target temperature of the battery needs to be stored.
In the present disclosure, the preset time period before the current time may be any preset time period before the current time.
In one embodiment, the preset time period before the current time may be a time period in which the NTC acquisition time is closest to the current time.
In the present disclosure, the target temperature of the battery in the preset time period before the current time is smoothed, and the smoothed target temperature of the battery is stored.
In step S32, the target temperatures are smoothed according to a preset smoothing coefficient, and smoothed target temperatures are obtained.
In the present disclosure, the preset smoothing coefficient is the number of target temperatures of the battery determined in a preset time period before the current time.
In the present disclosure, the target temperatures of the plurality of batteries may be smoothed to obtain the target temperature of the battery after the smoothing, and may be determined by using, for example, the following formula:
Tm＝(Tm-1+Tm-2+……Tm-n)/n
and the Tm-n to Tm are target temperatures of the battery, Tm is the target temperature of the battery stored at the mth time of the current time, n is a smoothing coefficient which is n sampling time points before the current time, and the stored target temperature of the battery is the average value of the target temperatures of the battery collected at the n sampling time points before the current time. The target temperature of the battery determined by n sampling time points before the current time is averaged, and the average value of the target temperature of the battery determined by n sampling time points before the current time is used as the target temperature of the battery stored for the mth time at the current time, so that the stored battery temperature is smooth and does not jump sharply.
In step S33, the target temperature of the battery after the smoothing process is stored.
In the present disclosure, in order to obtain the target temperature of the battery in time for a plurality of programs that need to call the target temperature of the battery, the target temperature of the battery after the smoothing process may be stored in a register.
In the exemplary embodiment of the disclosure, by storing the target temperature of the battery after the smoothing processing, a plurality of programs which need to call the target temperature of the battery can conveniently acquire the target temperature of the battery in time, and know the charging condition of the battery in time. By smoothing the target temperatures of the plurality of batteries determined in the preset time period before the current time and storing the target temperatures of the batteries after smoothing, the temperature jump of the stored batteries can be avoided from being too violent, and the accuracy of obtaining the target temperatures of the batteries is further improved.
Based on the same inventive concept, the disclosed embodiments provide a battery temperature determination apparatus.
