Problems solved by technology
[0005] However, heating the battery and fast charging will affect the user experience when the user uses it, that is, if the terminal temperature reaches a certain range, the user will feel a burning sensation when directly touching it.
In addition, if the user uses a large-scale game or other high-current operation, the terminal will generate a certain amount of heat, so if the battery continues to be heated, the heat inside the terminal will be further increased, and the temperature will be further increased, which will not only affect the life of the internal components of the terminal, but also It will also affect the user experience and cause security issues

The invention discloses a terminal and a charging control method and device thereof. The charging control method comprises the following steps: judging whether the current working state of a terminalis a resting state or a large-load running state; when the terminal is in a resting state, controlling to heat a battery to meet a first preset temperature range, and controlling to start an overspeedcharging mode for charging; and when the terminal is in a large-load operation state, controlling the terminal to preserve the temperature of the battery within a second preset temperature range, andcontrolling to start a normal quick charging mode for charging, wherein the second preset temperature range is lower than the first preset temperature range. According to the invention, under the condition that the external environment temperature is too low, the battery can be charged after the temperature of the battery rises in a battery heating or heat preservation mode, and the problem thatquick charging cannot be achieved due to the too low external environment temperature is solved.
Description
technical field [0001] The present application relates to the field of terminal charging, and in particular to a terminal and a charging control method and device thereof. Background technique [0002] In the current low temperature environment (ambient temperature below 0 degrees Celsius), the battery cannot be charged quickly, or the normal operation of the battery may be affected when the temperature is too low. Because the temperature is too low, on the one hand, the reaction speed inside the battery will decrease, and fast charging cannot be realized; Li dendrites penetrate the separator and short circuit occurs. Another reason for lithium precipitation is super-rate charging, that is, lithium dendrites will be formed on the negative electrode of the battery after exceeding the maximum charging current that the battery can withstand, which will cause the dendrites to pierce the separator and cause a short circuit. [0003] The current practice is to limit the temperat...
