Description

TECHNICAL FIELD The present disclosure relates to the technical field of charging, and more particularly, to a charging control method and apparatus, and an electronic device. BACKGROUND With the advancement of technology, terminal device products, such as mobile phones and tablet computers, have significantly improved in terms of charging speed and performance. High-power chargers, high-performance Central Processing Units (CPU) and Liquid Crystal Displays (LCD) with high refresh rates and other hardware are more widely applied to terminal device products. While these technologies enhance the user experience, they also introduce significant challenges related to power supply and heat generation. For example, when the power of a terminal device is very low, if a user needs to continue to use the terminal device at a high intensity, the user can only plug in the charger to maintain the power. One example is the patent publication CN 107 054 145. In such high-power-consumption charging scenario, not only the normal power supply of a terminal device system is affected, but also a phenomenon of rapid heat production of the terminal device caused by the superposition of charging temperature rise and high-load temperature rise appears, which leads to issues such as CPU frequency limitation, system jamming, significantly affecting the user experience.
