Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the invention, as detailed in the appended claims.
The voltage fluctuation is very large when the battery, such as a lithium battery, itself is affected by temperature. Therefore, if the same recharging threshold value is adopted at high temperature and low temperature, it is difficult to trigger the recharging of the battery, so that the electric quantity in the battery is consumed, and the use of a user is affected, or the recharging of the battery is continuously triggered, so that the service life of the battery is affected.
The present disclosure proposes a battery charging method in which a current temperature and a current voltage of a battery are first acquired, and a recharging voltage of the battery is determined based on the current temperature; it is then determined whether to charge the battery based on the current voltage and the recharging voltage. By adopting the method, the recharging voltage of the battery is dynamically adjusted according to the current temperature of the battery, so that the recharging times of the battery can be effectively reduced, and the service life of the battery is prolonged; and when the battery recharging method is applied to a high-temperature scene, recharging of the battery can be reasonably triggered, and influence on use of a user due to electric quantity depletion in the battery is avoided.
The method disclosed by the invention is suitable for all types of batteries with the battery capacity sensitive to temperature, and is particularly suitable for lithium batteries. The method of the present disclosure is therefore applicable to devices powered by the above-described batteries, including lithium batteries.
Fig. 1 is a flow chart illustrating a method of charging a battery, as shown in fig. 1, according to an exemplary embodiment, the method comprising the steps of:
step 101, acquiring the temperature and voltage of the battery;
step 102, determining a recharging voltage of the battery based on the temperature;
step 103, determining whether to charge the battery based on the voltage and the recharging voltage.
In step 101, the current temperature and the current voltage of the battery are obtained, and the obtaining manner may be obtained in a manner known to those skilled in the art, and will not be described herein.
In step 102, a recharging voltage of the battery, i.e. a recharging threshold value, is determined based on the acquired current temperature. That is, different complex charging voltages are determined for different battery temperatures, which sufficiently takes into account the effect of temperature on the highest voltage that the battery can be charged to.
In step 103, it is determined whether to charge the battery, i.e., whether to trigger recharging of the battery, based on a relationship between a current voltage of the battery and a recharging voltage (recharging threshold value). For example, when the current voltage of the battery is less than or equal to the recharging voltage, it is determined to trigger recharging of the battery.
By adopting the method, the recharging voltage of the battery is dynamically adjusted according to the current temperature of the battery, so that the recharging times of the battery can be effectively reduced, and the service life of the battery is prolonged; and when the battery recharging method is applied to a high-temperature scene, recharging of the battery can be reasonably triggered, and influence on use of a user due to electric quantity depletion in the battery is avoided.
In an alternative embodiment, said determining a recharging voltage of said battery based on said temperature comprises:
determining a peak voltage to which the battery can be charged based on the temperature;
determining the complex charging voltage based on the peak voltage.
In this embodiment, the peak voltage to which the battery can be charged is determined using the characteristics of the amount of electricity that the battery stores more at different temperatures, and then the complex charging voltage of the battery is determined based on the peak voltage. This avoids the above problems associated with applying phase-reversal charging voltages to different battery temperatures.
When determining the recharging voltage based on the peak voltage, the peak voltage may be determined as the recharging voltage, but this may result in triggering the recharging of the battery once the current voltage of the battery falls below the peak voltage, thereby causing the recharging of the battery to continue, affecting battery life. Therefore, a voltage value can be set, and the peak voltage is subtracted by the voltage value, so that the recharging can be reasonably triggered, and the continuous recharging of the battery can be avoided. The determination of the recharging voltage will be described below in connection with specific embodiments.
In an alternative embodiment, determining the peak voltage based on the temperature comprises:
determining the peak voltage to be a first peak voltage when the temperature is less than or equal to a threshold temperature;
determining the peak voltage to be a second peak voltage when the temperature is greater than the threshold temperature;
wherein the first peak voltage is greater than the second peak voltage.
When the battery is in a low-temperature state, the peak voltage which can be charged by the battery can reach the rated voltage of the battery; when the battery is in a high temperature state, the peak voltage that the battery can charge is less than the rated voltage of the battery. Therefore, in the method, the current temperature is determined to be in a low temperature range or a high temperature range by setting a threshold temperature and comparing the current temperature with the threshold temperature, and when the current temperature is in the low temperature range, the peak voltage is determined to be the first peak voltage; when in the high temperature range, the peak voltage is determined as a second peak voltage. It should be noted that the first peak voltage and the second peak voltage may be set according to a specific application scenario. From the above analysis, the first peak voltage is greater than the second peak voltage. A large number of experiments show that when the threshold temperature is set to 45 ℃, the low-temperature state and the high-temperature state of the battery can be well distinguished, and a good recharging effect is realized. For a common lithium battery, the peak voltage which can be charged is usually 4.1V when the temperature is higher than 45 ℃; at temperatures below 45 ℃, the peak voltage that can be charged is typically 4.4V. Therefore, the first peak voltage may be set to 4.4V, and the second peak voltage may be set to 4.1V.
In an alternative embodiment, said determining said complex charging voltage based on said peak voltage comprises:
determining a maintenance standby voltage, the maintenance standby voltage being a voltage required to maintain the battery-powered device in standby for a set period of time;
acquiring an adjusting voltage;
determining a result of subtracting the maintenance standby voltage and the adjustment voltage from the peak voltage as the complex charging voltage.
As described above, in order to not only trigger recharging properly but also prevent continuous recharging of the battery, a voltage value may be set, and the peak voltage may be subtracted from the voltage value. Therefore, in this embodiment, the sustain standby voltage and the adjustment voltage are acquired, and the result of subtracting the sustain standby voltage and the adjustment voltage from the peak voltage is determined as the complex charging voltage. Wherein, maintaining the standby voltage is the voltage required for maintaining the standby of a battery-powered device (such as a mobile phone) for a set time period; the voltage is adjusted to be the voltage required for avoiding the influence of internal resistance and current fluctuation on the recharging.
In an alternative embodiment, the obtaining the adjusted voltage includes:
acquiring the internal resistance and the standby current of the battery;
and multiplying the internal resistance by the standby current to obtain the adjusting voltage.
In this embodiment, the adjustment voltage is determined by the internal resistance of the battery and the standby current to avoid the influence on the triggering of the battery recharge due to the changes in the internal resistance of the battery and the standby current. Since the voltage is equal to the current multiplied by the resistance, the internal resistance is multiplied by the standby current to obtain the regulated voltage here. The standby current is a current passing through the battery when the battery is connected to the power supply and the battery-powered device is in standby.
In an alternative embodiment, the obtaining the internal resistance of the battery includes any one of the following:
in a first mode, the internal resistance is obtained based on the temperature;
and in the second mode, the battery is measured through an electricity meter to obtain the internal resistance.
In this embodiment, the calculation of the internal resistance of the battery required for adjusting the voltage can be obtained in two ways. Since the internal resistance of the battery varies with the temperature of the battery, the internal resistance can be obtained by the current temperature of the battery, for example, by looking up a temperature-internal resistance relation table. On the other hand, the battery internal resistance can also be obtained in real time by measuring the battery through the fuel gauge.
In an alternative embodiment, the determining the sustain standby voltage comprises:
determining the maintenance standby voltage based on the temperature and the set time period.
The standby voltage is a voltage consumed when a device (such as a mobile phone) which is powered by a battery is kept standby for a set time period (such as 10 hours) under the condition that the current battery is at a temperature. For example, when the battery is powered on and the battery is at a low temperature, the voltage required to maintain the mobile phone in a standby state for 10 hours is 100mV, and the standby voltage is 100 mV.
In an alternative embodiment, the value of the standby voltage is in the range of 50 to 300 mV.
The standby voltage is generally maintained within the range of 50-300 mV. Also, when the temperature is low, the required sustain standby voltage is relatively large. For example, when the battery temperature is less than 15 ℃, the standby voltage is maintained at 150 MV; when the battery temperature is more than 15 ℃, the standby voltage is maintained at 100 MV. This is because the power consumption of the battery in a low temperature state is high. Thus, in a particular implementation, different sustain standby voltages may be set depending on the current temperature of the battery.
In an alternative embodiment, the determining whether to charge the battery based on the voltage and the recharging voltage comprises:
determining to charge the battery when the voltage is less than or equal to the recharging voltage.
In the embodiment, whether the battery recharging is triggered or not is determined by judging the relation between the current voltage of the battery and the recharging voltage, so that the recharging frequency of the battery is reduced, unnecessary recharging is avoided, and the service life of the battery is prolonged.
Specific embodiments according to the present disclosure are described below in conjunction with specific application scenarios. In this embodiment, the battery is a lithium battery that powers the cell phone. This embodiment comprises the steps of:
step 201, obtaining the current temperature and the current voltage of the battery,
step 202, the current temperature is compared with a threshold temperature (45 ℃), and the current temperature is greater than the threshold temperature.
In step 203, the peak voltage is determined to be 4.1V.
In step 204, based on the current temperature, it is determined to maintain the standby voltage at 100 mV.
Step 205, based on the current temperature, a temperature-internal resistance relation table is searched to obtain the current battery internal resistance.
Step 206, measuring the standby current of the battery.
And step 207, multiplying the internal resistance of the battery by the standby current to obtain the regulated voltage.
And step 208, subtracting the maintaining standby voltage and the adjusting voltage from the peak voltage to obtain a complex charging voltage.
Step 209, when the current voltage is less than or equal to the recharging voltage, recharging the battery.
The above embodiment is exemplified by the case where the present temperature is greater than the threshold temperature, and when the present temperature is less than or equal to the threshold temperature, the peak voltage is determined to be 4.4V. By adopting the method, the peak voltage of the battery is dynamically adjusted according to the current temperature of the battery, and then the recharging voltage is adjusted. Therefore, the battery recharging times can be effectively reduced, the service life of the battery is prolonged, the battery recharging can be reasonably triggered when the battery recharging device is applied to a high-temperature scene, and the influence on the use of a user due to the exhaustion of the electric quantity in the battery is avoided.

determining the complex charging voltage based on the peak voltage.
In an alternative embodiment, the first determining module 302 is further configured to:
