Description

Electric vehicle charging device composed of metal fuel cell and operation mode

Technical field

The invention belongs to the field of electric vehicles, and particularly relates to the structure and operation mode of an electric vehicle charging device composed of a metal fuel cell.

Background technique

With the depletion of fossil energy and the increasing strengthening of environmental protection, the development of green, safe and efficient electric vehicles to replace traditional fuel vehicles has become the development direction of the automotive industry. At present, commercial power batteries for electric vehicles mainly include lead-acid batteries, lithium-ion batteries, and nickel-hydrogen batteries. Although electric vehicles have been used currently, electric vehicles using lead-acid batteries, lithium-ion batteries, nickel-hydrogen batteries, etc. as power batteries have short cruising range and long charging time, which cannot meet the needs of many applications. In addition, the coverage rate of charging piles used to charge electric vehicles is low, especially when there is no electricity, the problem of difficult charging of electric vehicles becomes more serious.

Metal fuel cell, also known as metal-air cell, is a chemical battery with high specific energy. The metal fuel cell is composed of a metal negative electrode (such as aluminum, lithium, magnesium, zinc and other electrochemically active metals and their alloys), an air electrode (anode), an electrolyte, and a battery cavity. During the discharge process of the metal fuel cell, the metal anode and oxygen are consumed to output electrical energy. At present, metal fuel cells mainly include aluminum fuel cells, lithium fuel cells, magnesium fuel cells, and zinc fuel cells. Compared with lead-acid batteries, lithium-ion batteries, nickel-hydrogen batteries and other power batteries, metal fuel cells have the advantages of high specific energy, high specific power, stable discharge voltage, safe operation, environmental friendliness, abundant resources, and recyclability. In addition, the metal fuel cell does not require charging. The oxygen consumed during the discharge process of the metal fuel cell can come from air, and the metal negative electrode consumed during the discharge process can be replenished by replacing the metal negative electrode with a new one to ensure that the metal fuel cell discharges continuously and efficiently. The operation of replacing the metal negative electrode is simple and convenient, which can be completed in 2-5 minutes, which is much shorter than the refueling time of a fuel vehicle. Metal fuel cells completely solve the problem of long charging time and the need to build a large number of charging piles for power batteries such as lead-acid batteries, lithium-ion batteries, and nickel-hydrogen batteries.
