Embodiment approach

[0031] Method 1. The inverter 3 can only convert the first AC power into the first DC power of the third voltage level based on the charging command, that is, only the first AC power generated by the new energy power generation device 1 is used to replace the battery 4 at this time. to charge.

[0032] Method 2. The inverter 3 can convert both the first AC power and the second AC power into the first DC power of the third voltage level based on the charging command, that is, the first AC generated by the new energy power generation device 1 can be used at the same time. The electric energy, as well as the second AC electric energy output by the grid, charges the swap battery 4 .

[0033] Method 3: The inverter 3 can only convert the second AC power into the first DC power of the third voltage level based on the charging command, that is, only the second AC power output from the grid is used to charge the swap battery 4 at this time.

[0034] In the embodiment of the present d...

Abstract

The invention discloses a substation. The swap station includes: a new energy generating device, a grid access device, an inverter, a battery swap, and a controller; the new energy generating device is used to convert new energy into the first AC power of the first voltage level, and output the first AC power of the first voltage level. An AC power; the grid access device is used to receive the second AC power of the second voltage level from the power grid, and output the second AC power; the controller is used to send a charging command to the inverter, and the inverter can be based on the charging command. At least one of the first AC power and the second AC power is converted into the first DC power of the third voltage level, and the battery is charged by using the first DC power. As a result, the power exchange station includes new energy power generation devices and grid access devices, which can combine the AC power generated by the new energy power generation devices and the grid, and the charging method is more flexible, which improves the stability and reliability of the power supply of the power exchange station. Meet the user's electricity demand.

Description

technical field [0001] The invention relates to the technical field of charging, in particular to a power station. Background technique [0002] At present, electric energy has been widely used in people's daily life. For example, sweeping robots, electric kettles, and induction cookers in household appliances are convenient and fast, which can greatly reduce people's housework burden. less pollution. In the prior art, the electrical equipment can be charged through the power exchange station. However, the charging method of the existing power exchange station is not flexible enough, and the stability and reliability of the power supply of the power exchange station are low, which cannot meet the electricity demand of users. Contents of the invention [0003] The present invention aims to solve one of the technical problems in the above-mentioned technologies at least to a certain extent. [0004] Therefore, the first purpose of the present invention is to propose a powe...
