Abstract

The invention provides a hybrid power supply employing a metal air fuel cell and a lithium-ion battery and a control method. The hybrid power supply comprises the metal air fuel cell, the lithium-ionbattery and a power output port, wherein a positive electrode of the metal air fuel cell is connected with the positive electrode of the lithium-ion battery and a positive input end of the power output port separately; a negative electrode of the metal air fuel cell is connected with the negative electrode of the lithium-ion battery and a negative input end of the power output port separately; thepositive electrode of the lithium-ion battery is connected with the positive input end of the power output port; and the negative electrode of the lithium-ion battery is connected with the negative input end of the power output port. According to the hybrid power supply, the advantages of high capacity of the metal air fuel cell and large power output of the lithium-ion battery are developed, andthe lithium-ion battery is continuously or intermittently charged through the metal air fuel cell, so that a portable power supply system combines relatively high endurance with medium-high power carrying capacity.

Description

technical field [0001] The invention relates to the field of batteries, in particular to a portable power supply in which a metal air fuel cell and a lithium ion battery are mixed. Background technique [0002] With the rapid development of information technology today, a variety of multi-functional portable electronic devices for communication, navigation, night vision, medical treatment, and weather are widely used in fields such as field exploration, emergency rescue, fire protection, and security. , the above-mentioned power demand has put forward new requirements and challenges to the portable power supply. Specifically, the portable power supply should have the characteristics of light weight, small size, stable power output, strong battery life, low heat generation, and good environmental adaptability. [0003] Metal-air fuel cells have the characteristics of large capacity but small output power, and cannot be used for high-power loads; while lithium-ion batteries h...
