Abstract

The invention discloses a mobile power supply with a heating device. The mobile power supply comprises a mobile power supply shell, a lithium battery and a microprocessor, wherein the lithium battery and the microprocessor are arranged inside the mobile power supply shell in a locating manner; a temperature sensor and a heating element are also arranged on the mobile power supply shell in a locating manner; the temperature sensor is used for sensing a temperature signal of the heating element, and transmitting the temperature signal to the microprocessor; the microprocessor controls the heating element to be connected and disconnected with the lithium battery. Thus, the temperature of the mobile power supply can be automatically adjusted, and the charge and discharge effects of the mobile power supply are effectively ensured. In addition, heat emitted from the mobile power supply also can be used for warming hands of a user and the like, resources are fully utilized, and the mobile power supply is low in consumption but high in efficiency.

Description

technical field [0001] The invention relates to the technical field of mobile power supplies, and specifically provides a mobile power supply with a heating device. Background technique [0002] Mobile power is a portable charger that integrates power supply and charging functions. It can charge mobile phones and other digital devices anytime, anywhere or provide standby power, so it is more and more closely related to our daily life. [0003] However, since the electrochemical reaction on the electrode / electrolyte interface of the battery is related to the ambient temperature, changes in the ambient temperature will have a great impact on the charging and discharging performance of the mobile power battery, that is, when the ambient temperature is too high or too low, It will destroy the chemical balance in the battery, affect the reaction rate of the battery electrode / electrolyte, and then affect the output power of the battery. Contents of the invention [0004] In ord...
