The invention discloses electronic equipment and a charging method and device, and belongs to the field of terminals. The electronic equipment comprises a battery, a first circuit board, a heating element and a charging interface module, the input end of the charging interface module can be connected with an external power supply in a pluggable mode, the output end of the charging interface moduleis electrically connected with the input end of the first circuit board, the output end of the first circuit board is electrically connected with the battery, and the first circuit board charges thebattery; the output end of the charging interface module is electrically connected with the heating element, and the heating element heats the battery. Therefore, the heating element is additionally arranged in the electronic equipment; therefore, when the battery is charged, under the condition that the temperature of the battery is relatively low, the charging interface module can charge the battery on one hand and can supply power to the heating element on the other hand so as to rapidly heat the battery, so that the temperature of the battery is increased, the charging speed of the batteryis not influenced by low temperature, and the charging speed of the battery is further increased.
Description
technical field [0001] The present application belongs to the field of terminals, and specifically relates to an electronic device, a charging method and a device. Background technique [0002] At present, the batteries installed in most electronic devices are lithium batteries. When charging the lithium battery, the positive electrode of the lithium battery can generate lithium ions, and the lithium ions can diffuse to the negative electrode of the lithium battery through the electrolyte, and combine with the electrons of the negative electrode. , and an electrochemical reaction occurs to generate energy changes, thereby completing the charging process. [0003] However, in the course of implementing the present application, the inventors have found that at least the following problems exist in the prior art: the diffusion rate of lithium ions slows down under low temperature conditions, which causes the charging speed of lithium batteries to decrease, and even the problem ...
