Special high-power charging equipment powered by aluminum-air batteries

Abstract

The invention discloses special high-power charging equipment powered by aluminum-air batteries. The charging equipment comprises an aluminum-air battery power management system and multiple aluminum-air batteries, wherein the multiple aluminum-air batteries are electrically connected with the aluminum-air battery power management system after being in serial connection; the aluminum-air battery power management system converts electricity generated by the multiple aluminum-air batteries and conveys the electricity to an external target rechargeable battery, and the external target rechargeable battery starts a charging state. The equipment further comprises multiple voltage detection modules which input detected information of the aluminum-air batteries to a master controller in the aluminum-air battery power management system, the operation conditions of the aluminum-air batteries are adjusted by an aluminum-air battery control module, so that the external target rechargeable battery can be charged. The charging equipment does not need an external power grid, is free from geographical limitations and does not need capacity of any power grid, energy is supplied by aluminum and air which are easy to obtain, the charging current is strong, the equipment is movable, the investment cost is low, and massive stationing and networking are facilitated.

Description

technical field [0001] The invention relates to the technical field of charging equipment powered by chemical batteries, in particular to a special high-power charging equipment powered by an aluminum-air battery. Background technique [0002] The depletion of fossil energy and the exhaust emission of fossil energy vehicles have seriously affected the living environment of human beings. Therefore, the energy use revolution of electric vehicles with no pollution exhaust emissions has been opened. At the same time, various rechargeable battery packs are also used in aerospace, national defense, military, It has been widely used in many industries and fields such as scientific research institutes, public transportation, and port transportation. At present, the charging method is mainly to convert the electric energy of the power grid into the target battery pack through the charging equipment. [0003] The working principle of the existing AC (direct) charging equipment is usua...

Problems solved by technology

In addition, because there are other electric and electrical equipment in use on the public grid, the THD value of the power harmonic content of the charging equipment must be less than 3%. additional cost

For off-grid solar charging stations, since the charging equipment needs a large amount of power capacity to work, it must be equipped with enough energy storage battery packs to supply power to the charging equipment, and a large number of solar panels can only trickle charge the energy storage battery packs, while solar panels The conversion efficiency of electric energy is limited and is severely restricted by the regional weather, and it cannot generate electric energy to charge the energy storage battery pack at night. The capacity of the energy storage battery pack and the capacity and area of ​​the solar panel determine the charging efficiency of the charging equipment, which also makes it difficult to build electric vehicles. Solar charging stations are expensive

For another off-grid charging station usage, gasoline and diesel generator sets are used as the energy source to connect to the charging equipment. Although it can be made into a carriage, it is large in size, poor in maintainability, high in cost, polluting exhaust gas, and fuel storage and use. There are hidden dangers in the use of fire safety. At present, only small diesel generators are used as on-board chargers. The off-grid trickle charging mode makes it difficult for users to accept too long charging time, and the efficiency is lower than that of original diesel gasoline vehicles.
