Description
Technical Field

Background
Generally, electric energy cannot be stored (the current battery energy storage has high cost and limited energy storage), so that how much electric energy is needed by a user, how much electric energy needs to be synchronously generated by a thermal power plant, and energy waste cannot be caused. However, the required electrical load of each thermal power plant in the power system is usually changed constantly, and in order to maintain the active power balance and keep the system frequency stable, the power generation department needs to change the power generation amount of the generator correspondingly to adapt to the change of the electrical load, which is called peak shaving.
In the three northeast regions of China, the capacity of an electric power market is rich, peak-adjustable power supplies such as a gas turbine and pumped storage are scarce, the contradiction between peak adjustment of a power grid and the flexibility of a thermal power generating unit is prominent, the capacity of the power grid for absorbing new energy such as wind power, photoelectricity, hydropower and nuclear power is insufficient, and the phenomena of wind abandoning, light abandoning, water abandoning and nuclear power abandon are serious.
On the other hand, under the high concern of global energy conservation and environmental protection, new energy automobiles are in the process of transportation, and in recent years, the market of the new energy automobiles in China is continuously heated and is in a rapid development state.

The battery replacement mode based on the battery rental mode in cooperation with the large-scale centralized charging has become a competitive business technology mode for the development of the current electric vehicles, because: 1) the car purchasing cost of the user can be reduced by adopting a battery rental mode; 2) the centralized charging of the battery can adopt a slow charging mode, so that the shortening of the service life of the battery caused by improper charging is avoided; 3) the fluctuation of the power grid caused by random charging of the electric automobile can be reduced by carrying out centralized management on the batteries; 4) the battery under the replacement can be utilized in echelon at the centralized charging station, so that the utilization rate of the battery is improved, and the secondary pollution of the battery to the environment is reduced.
The battery swapping mode based on battery lease is practically applied and popularized in countries such as Israel, Canada, Australia and Denmark; as an active participant in the electric vehicle industry, the national grid company and the southern grid company are also preparing to adopt an electric vehicle development mode mainly for battery replacement, and in terms of charging, the national grid company also defines a business mode of "centralized charging and unified distribution".
However, the current flow electric fuel has low energy density and complicated battery replacement operation, and if the battery replacement can be conveniently realized by using a charge-discharge battery in a fluid state, the electric automobile in a battery rental or replacement mode can be more feasible in the future.
The redox flow battery is different from a conventional solid battery or a conventional redox flow battery, and the redox flow battery charger and the redox flow battery work independently, so that the storage and the release of fluidized electric energy can be realized. The method is applied to the electric automobile, can provide longer endurance mileage, can realize that the charging process of the battery is a refueling process (full-electricity electric fuel injection), and can be completed within a few minutes.
