Detailed Description
Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
The embodiment of the invention provides a low-voltage linear charging method, aiming at the problems that a linear charging scheme generates heat seriously when using large current for charging, the charging efficiency is influenced, and a nonlinear charging scheme is expensive in the prior art.
The first embodiment:
referring to fig. 1, the low voltage linear charging method includes:
and step 12, adjusting the output voltage value of the adapter according to the voltage value of the battery.
Specifically, in the foregoing embodiment, in step 12, the adjusting the output voltage value of the adapter according to the voltage value of the battery specifically includes: adjusting an output voltage value of the adapter to vary as a voltage value of the battery varies. Namely, when the voltage of the battery changes and the charging current becomes large, the adapter automatically adjusts the output voltage, namely, the adapter reduces the output voltage according to the voltage of the battery, so that even if the output current becomes large, the charging switch does not generate heat seriously.
In the above embodiment of the present invention, the voltage value of the battery is obtained during the charging process; and then adjusting the output voltage value of the adapter according to the voltage value of the battery. The problems that the charging switch generates heat seriously and the charging efficiency is reduced can not occur even if large-current charging is adopted. Effectively shortens the charging time, reduces the heat productivity and improves the competitiveness of the product.
Second embodiment:
referring to fig. 2, an embodiment of the present invention further provides an adapter 21, where the adapter 21 includes:
an obtaining module 22, configured to obtain a voltage value of the battery during a charging process;
and the adjusting module 23 is configured to adjust the output voltage value of the adapter according to the voltage value of the battery.
Wherein, the adjusting module 23 is specifically configured to: further adjusting the output voltage value of the adapter to vary as the voltage value of the battery varies. That is, when the voltage of the battery acquired by the acquiring module 22 changes and the charging current becomes larger, the adjusting module 23 adjusts the output voltage of the adapter 21, that is, the adjusting module 23 makes the adapter 21 reduce the output voltage according to the voltage of the battery, so that even if the charging current becomes larger, the charging switch does not generate heat seriously.
Referring to fig. 3, fig. 3 is a flowchart illustrating the operation of the adapter according to the embodiment of the present invention. The adapter 21 is connected to a battery 25 via a charging switch 24. In the prior art, when a large current is used for charging, the charging switch 24 generates heat seriously, and the charging efficiency is reduced. The adapter 21 is therefore provided in this embodiment with an acquisition module 22 and an adjustment module 23. Wherein the obtaining module 22 is used for obtaining the voltage of the battery 25 during the charging process and transmitting the obtained voltage of the battery 25 to the adjusting module 23. The adjusting module 23 adjusts the output voltage value of the adapter 21 according to the voltage value of the battery 25.
The specific adjustment manner of the adjustment module 23 is that when the voltage of the battery 25 changes, the charging current becomes larger. The output voltage of the adapter 21 is adjusted to vary with the voltage of the battery 25, specifically, the output voltage of the adapter 21 is made smaller. Thus, even if the charging current is increased, the charging switch does not generate heat seriously. The charging efficiency is guaranteed.
The terminal embodiment of the invention also obtains the voltage value of the battery in the charging process; and then adjusting the output voltage value of the adapter according to the voltage value of the battery. The problems that the charging switch generates heat seriously and the charging efficiency is reduced can not occur even if large-current charging is adopted. Effectively shortens the charging time, reduces the heat productivity and improves the competitiveness of the product.
While the foregoing is directed to the preferred embodiment of the present invention, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention as defined in the appended claims.
