请参阅图 1 , 图 1为本发明提供的基于移动终端在不同温度下充 电的充电方法第一实施例的流程图, 包括以下步骤: Referring to FIG. 1 , FIG. 1 is a flowchart of a first embodiment of a charging method based on charging a mobile terminal at different temperatures according to the present invention, including the following steps:
步骤 S100、 移动终端检测电池是否在充电; Step S100: The mobile terminal detects whether the battery is charging;

下面结合具体的实施例对上述步骤进行详细的描述。 The above steps are described in detail below in conjunction with specific embodiments.
在步骤 S100中, 移动终端检测电池是否在充电, 即是否有充电 器在对移动终端中的电池进行充电。 当电池没有在充电时, 软件保持 等待, 不触发后续流程。 当电池在充电时,软件触发,进入后续流程。 In step S100, the mobile terminal detects whether the battery is charging, i.e., whether or not the charger is charging the battery in the mobile terminal. When the battery is not charging, the software remains waiting and does not trigger subsequent processes. When the battery is charging, the software triggers and proceeds to the subsequent process.
在步骤 S200中, 实时检测移动终端的充电电路与电池的热敏电 阻相连的电池温度监测输入端 VBAT TEMP 的电压值, 自动查询预
先存储的电池温度监测输入端 VB AT— TEMP 的电压值与电池温度的 关系表, 从而得出当前电池温度。 具体来说, 其工作原理如下: 所述 电池温度也就是电池的充电温度, 在充电的过程中, 电池的温度会不 断的变化 ,移动终端的充电电路的电池温度监测输入端 VB AT— TEMP 串联连接电池的热敏电阻,由于热敏电阻的阻值随着温度的升高而减 少, 导致电池温度监测输入端 VBAT— TEMP的电压值也会随着改变。 在实际应用时, 所述热敏电阻即 NTC电阻的阻值为 10K欧姆, 软件 测量电池温度监测输入端 VB AT— TEMP 的分压的电压值便可判断电 池温度。 所述电池温度监测输入端的电压值与电池温度的关系表, 是 通过大量的实验测量得出来的,譬如可通过多次测量充电过程中不同 温度时对应的电压值, 然后求平均, 从而得出所述关系表。 如下表 1 所示,表 1为本发明提供的基于移动终端在不同温度下充电的充电方 法的电池温度监测输入端的电压值与电池温度的关系表。
In step S200, the voltage value of the battery temperature monitoring input terminal VBAT TEMP connected to the thermistor of the battery of the charging circuit of the mobile terminal is detected in real time, and the automatic inquiry is performed. The stored battery temperature monitors the voltage value of the input VB AT-TEMP and the battery temperature to obtain the current battery temperature. Specifically, the working principle is as follows: The battery temperature is also the charging temperature of the battery. During the charging process, the temperature of the battery will continuously change, and the battery temperature monitoring input terminal of the charging circuit of the mobile terminal is connected in series with VB AT-TEMP. Connect the battery's thermistor, as the resistance of the thermistor decreases with increasing temperature, the voltage value of the battery temperature monitoring input VBAT-TEMP will also change. In practical applications, the resistance of the thermistor, that is, the NTC resistor is 10K ohms, and the software measures the voltage value of the divided voltage of the battery temperature monitoring input terminal VB AT-TEMP to determine the battery temperature. The relationship between the voltage value of the battery temperature monitoring input terminal and the battery temperature is obtained by a large number of experimental measurements, for example, by measuring the corresponding voltage value at different temperatures during the charging process, and then averaging, thereby obtaining The relationship table. As shown in Table 1 below, Table 1 is a table showing the relationship between the voltage value of the battery temperature monitoring input terminal and the battery temperature based on the charging method of the mobile terminal charging at different temperatures provided by the present invention.
表 1 Table 1
从表 1 中可以看出, 当电压值为 1.351V时, 电池温度为 0°C ; 当电压值为 0.912V时, 电池温度为 30°C ; 当电压值为 0.722V时, 电池温度为 45 °C。 需说明的是, 表 1 中所示电池温度监测输入端 VB AT— TEMP的电压值与电池温度的关系是一种示例 ,本领域普通技 术人员可根据实际需要进行设置或更改,或者将两者对应关系更加细 化, 譬如温度每升高一度便对应一个电压值。 As can be seen from Table 1, when the voltage value is 1.351V, the battery temperature is 0 °C; when the voltage value is 0.912V, the battery temperature is 30 °C; when the voltage value is 0.722V, the battery temperature is 45 °C. It should be noted that the relationship between the voltage value of the battery temperature monitoring input terminal VB AT_TEMP and the battery temperature shown in Table 1 is an example, and those skilled in the art can set or change according to actual needs, or both. The correspondence is more refined, for example, every time the temperature rises, it corresponds to a voltage value.
进一步地, 在所述步骤 S100之前还包括: 将电池的充电温度的
最高值设为 60°C。 由于锂电池的充电温度一般为 0°C -45 °C , 本发明 将其范围调整为 0°C-60°C ,从而大大方便了用户的使用,特别是方便 了气温较高地区的用户的使用,防止正常使用时出现由于气温较高而 无法充电的情况。 如图 2所示, 当电压值为 0.669V时, 电池温度为 50 °C ; 当电压值为 0.576V时, 电池温度为 60°C。 Further, before the step S100, the method further includes: charging a battery The highest value is set to 60 °C. Since the charging temperature of the lithium battery is generally 0 ° C -45 ° C, the present invention adjusts the range to 0 ° C - 60 ° C, thereby greatly facilitating the use of the user, especially for users in areas with higher temperatures. Use to prevent the situation from being unable to charge due to high temperature during normal use. As shown in Figure 2, when the voltage value is 0.669V, the battery temperature is 50 °C; when the voltage value is 0.576V, the battery temperature is 60 °C.
在步骤 S300中, 根据得出的当前电池温度, 查询预先存储的电 池温度与充电电压和充电电流的关系表,并从所述电池温度与充电电 压和充电电流的关系表找出与所述当前电池温度对应的充电电压和 充电电流, 对应设置为当前充电电压和充电电流。 即在关系表中找出 在不同温度下对电池充电的充电电压值和充电电流的电流值,将电池 的充电电压和充电电流对应设置为不同温度对应的充电电压和充电 电流。 其中, 所述电池温度与充电电压和充电电流的关系表, 是通过 大量的实验测量得出来的,譬如可通过多次测量充电过程中不同电池 温度时对应的充电电压的电压值和充电电流的电流值, 然后求平均, 从而得出所述关系表。 In step S300, according to the obtained current battery temperature, query a table of relationship between the pre-stored battery temperature and the charging voltage and the charging current, and find out from the relationship between the battery temperature and the charging voltage and the charging current. The charging voltage and charging current corresponding to the battery temperature are set to the current charging voltage and charging current. That is, in the relationship table, the charging voltage value and the charging current value of charging the battery at different temperatures are found, and the charging voltage and the charging current of the battery are correspondingly set to the charging voltage and the charging current corresponding to different temperatures. Wherein, the relationship between the battery temperature and the charging voltage and the charging current is obtained through a large number of experimental measurements, such as by measuring the voltage value and the charging current of the corresponding charging voltage at different battery temperatures during the charging process. The current values are then averaged to derive the relationship table.
在步骤 S400中,在调整对电池充电的充电电压和充电电流之后, 随着充电进行, 电池温度还会发生变化, 当电池未充满时, 返回步骤 S200, 继续检测电池温度监测输入端 VB AT— TEMP的电压值, 得出 当前电池温度, 再调整其充电电流和充电电压; 当电池充满时, 控制 结束充电, 即直至电池充满, 即充电完成。 In step S400, after adjusting the charging voltage and the charging current for charging the battery, as the charging progresses, the battery temperature also changes. When the battery is not full, the process returns to step S200, and the battery temperature monitoring input terminal VB AT is continuously detected. The voltage value of TEMP gives the current battery temperature, and then adjusts its charging current and charging voltage. When the battery is full, the control ends charging, that is, until the battery is full, that is, charging is completed.
本发明提供的基于移动终端在不同温度下充电的充电方法,使得 在电池的充电过程中,可根据不同的温度适配调整对电池的充电电压
和充电电流, 从而保护了电池, 延长了寿命; 起到了控制电池内阻和 厚度的作用, 即减少电池鼓胀现象。 The invention provides a charging method based on charging a mobile terminal at different temperatures, so that during charging of the battery, the charging voltage of the battery can be adjusted according to different temperature adaptations. And charging current, thus protecting the battery, extending the life; play a role in controlling the internal resistance and thickness of the battery, that is, reducing the battery bulging phenomenon.
进一步地, 在所述步骤 S100和 S200之间, 还包括: 步骤 S210、 移动终端检测电池的 ID电阻的电压值来识别电池的类型, 并设置充 电过程中的充电截止电压。 这样, 通过预先识别电池的类型, 从而采 用不同的充电电压和充电电流来对该电池充电, 大大提高了兼容性。 Further, between the steps S100 and S200, the method further includes: Step S210: The mobile terminal detects a voltage value of the ID resistance of the battery to identify the type of the battery, and sets a charging cutoff voltage during the charging process. Thus, by pre-identifying the type of battery, different charging voltages and charging currents are used to charge the battery, which greatly improves compatibility.
进一步地, 所述步骤 S210具体包括: 当移动终端检测电池的 ID 电阻的电压值在第一预定电压范围时, 所述电池为 4.2V电池, 其截 止电压为 4.2V; 当移动终端检测到电池的 ID电阻的电压值在第二预 定电压范围时, 所述电池为 4.35V电池, 其截止电压为 4.35V。 Further, the step S210 specifically includes: when the mobile terminal detects that the voltage value of the ID resistance of the battery is in the first predetermined voltage range, the battery is a 4.2V battery, and the cutoff voltage is 4.2V; when the mobile terminal detects the battery When the voltage value of the ID resistor is in the second predetermined voltage range, the battery is a 4.35V battery, and its cutoff voltage is 4.35V.
具体来说, 所述移动终端为手机或平板电脑等移动便携设备, 特 别是以锂离子电池作为电源的移动终端。此处以手机为例,进行说明。 手机锂离子电池的有两种, 一种充电截止电压为 4.2V, 即为 4.2V电 池; 另外一种充电截止电压 4.35V, 即为 4.35V 电池。 4.2V 电池和 4.35V电池分别有不同的 ID电阻, 通过识别电池的 ID电阻的电压值 VBAT ID, 来判断移动终端中的电池是 4.2V电池还是 4.35V电池, 从而对应设置电池的充电截止电压, 来防止使用 4.35V电压对 4.2V 电池充电, 从而避免发生对 4.2V电池进行过充的情况。 优选地, 所 述第一预定电压范围为 50-150mV ; 所述第二预定电压范围为 600-700mV。 在实际应用时, 由于目前电池上使用的 ID电阻大多为 10K和 100K的电阻,电池的 ID电阻的电压值 VBAT— ID分别为 98mV 与 657mV。 这样通过检测电池的 ID电阻的电压值便可以有效识别、
正确区分不同电池。 Specifically, the mobile terminal is a mobile portable device such as a mobile phone or a tablet computer, and particularly a mobile terminal using a lithium ion battery as a power source. Here, the mobile phone is taken as an example for explanation. There are two types of mobile phone lithium-ion batteries, one is 4.2V, which is a 4.2V battery; the other is 4.35V, which is 4.35V. The 4.2V battery and the 4.35V battery respectively have different ID resistors. By identifying the voltage value VBAT ID of the battery ID resistor, it is judged whether the battery in the mobile terminal is a 4.2V battery or a 4.35V battery, thereby correspondingly setting the charging cutoff voltage of the battery. , to prevent the use of 4.35V voltage to charge the 4.2V battery, thus avoiding the overcharge of the 4.2V battery. Preferably, the first predetermined voltage range is 50-150 mV; and the second predetermined voltage range is 600-700 mV. In practical applications, since the ID resistors currently used on batteries are mostly 10K and 100K resistors, the voltage value of the ID resistance of the battery is VBAT-ID of 98mV and 657mV, respectively. This can be effectively identified by detecting the voltage value of the ID resistance of the battery. Correctly distinguish between different batteries.
进一步地, 当移动终端检测到电池的 ID电阻的电压值在第一预 定电压范围时, 即移动终端中的电池为 4.2V电池时, 所述步骤 S300 具体包括: 根据当前电池温度, 查询预先存储的 4.2V电池的电池温 度与充电电压和充电电流的关系表, 对应改变当前对 4.2V电池充电 的充电电压和充电电流。下表 2为本发明提供的基于移动终端在不同 温度下充电的充电方法的 4.2V电池的电池温度与充电电压和充电电 流的关系表。
Further, when the mobile terminal detects that the voltage value of the ID resistance of the battery is in the first predetermined voltage range, that is, the battery in the mobile terminal is a 4.2V battery, the step S300 specifically includes: querying the pre-storage according to the current battery temperature. The relationship between the battery temperature of the 4.2V battery and the charging voltage and charging current corresponds to changing the current charging voltage and charging current for charging the 4.2V battery. Table 2 below is a table showing the relationship between the battery temperature of the 4.2V battery and the charging voltage and the charging current based on the charging method of the mobile terminal charging at different temperatures according to the present invention.

This is because the voltage value and current value will fluctuate a little during the charging process and cannot be kept absolutely unchanged. Do not explain too much here), read the corresponding parameter value. The voltage value and current value are set to the current battery charging voltage and charging current.
当移动终端检测到电池的 ID电阻的电压值在第二预定电压范围 时, 即移动终端中的电池为 4.35V电池时, 所述步骤 S300具体包括: 当移动终端检测到电池为 4.35V电池时, 根据当前电池温度, 查询预 先存储的 4.35V电池的电池温度与充电电压和充电电流的关系表,对 应改变当前对 4.35V电池充电的充电电压和充电电流。如下表 3所示,

When the mobile terminal detects that the voltage value of the ID resistance of the battery is in the second predetermined voltage range, that is, the battery in the mobile terminal is a 4.35V battery, the step S300 specifically includes: when the mobile terminal detects that the battery is a 4.35V battery According to the current battery temperature, the relationship between the battery temperature of the pre-stored 4.35V battery and the charging voltage and the charging current is checked, and the charging voltage and charging current for charging the current 4.35V battery are changed correspondingly. As shown in Table 3 below, Table 3 is a table showing the relationship between the battery temperature of the 4.35 V battery and the charging voltage and the charging current based on the charging method of the mobile terminal charging at different temperatures according to the present invention.
表 3 table 3
从表 3 中可以看出, 当当前的电池温度, 即充电温度在 0°C-10 °C之间或 10°C -45 °C之间时,对应的充电电压和充电电流如表 3所示, 读取对应的参数值并将电压值和电流值设置为当前电池的充电电压 和充电电流。 As can be seen from Table 3, when the current battery temperature, that is, the charging temperature is between 0 °C and 10 °C or between 10 °C and 45 °C, the corresponding charging voltage and charging current are shown in Table 3. , read the corresponding parameter value and set the voltage value and current value to the current battery charging voltage and charging current.
