Description

Technical Field

[0001] The utility model relates to the technical field of power supplies, in particular to a multifunctional power supply. Background Art

[0002] With the popularity of mobile devices such as smartphones, tablets, and laptops, people have an increasing demand for charging anytime and anywhere. In situations where it is inconvenient to connect to the mains for charging, such as outdoor activities, travel, and work, a portable power source is usually used to charge the device to avoid the device being unable to be used due to insufficient power. Existing portable power sources are mainly lithium-ion batteries, but the capacity of lithium-ion batteries gradually decreases with the increase in the number of charge and discharge times, resulting in a shortened service life of lithium-ion batteries, which cannot meet the charging needs of users; the existing technology uses metal fuel cells as a power source, but the existing technology still has the following technical problems:

[0003] 1. Metal fuel cells use active solid metals (such as aluminum, zinc, lithium, magnesium, etc.) as negative electrodes, oxygen as positive electrodes, and alkaline solutions or neutral salt solutions as electrolytes. Therefore, when using them, it is necessary to add or discharge the electrolyte and replace the negative electrode metal. However, the operations of adding or discharging the electrolyte and replacing the negative electrode metal in metal fuel cells of the prior art are extremely cumbersome.

[0004] 2. Although metal fuel cells, such as aluminum-air batteries, have advantages such as large power storage, low production cost, and long storage life, they are not suitable for long-term use due to their low power density and short service life.

[0005] 3. After the metal fuel cell is used and the electrolyte is discharged, a large amount of electrolyte remains on the negative electrode metal, causing serious corrosion of the negative electrode metal, reducing the utilization rate of the negative electrode metal, and causing energy waste.

The voltage sensor, current sensor, and temperature sensor send the output voltage, current, and temperature signals of the metal fuel cell group 2, the lithium-ion battery 4, and the total output circuit to the main control board 6 in real time.

When there is no external load and the power of the lithium-ion battery 4 is less than the set value, the electric energy output by the metal fuel cell group 2 charges the lithium-ion battery 4; when the power of the external load is less than the set value and the power of the lithium-ion battery 4 is less than the set value, the metal fuel cell group 2 charges the lithium-ion battery 4, and at the same time, after conversion by the DC / AC inverter module and the DC / DC module, it is output through the AC interface, USB interface, Type-C interface, iPhone interface, etc. to power the external load.
