Description

Power generation circuit of electric yacht Technical Field The application relates to the field of electric yachts, in particular to a power generation circuit of an electric yacht. Background With the development of technology and the improvement of environmental awareness, the intelligent energy source for users gradually becomes trend. The space of peasant household roof, villa, sunshine room, terrace etc. is utilized effectively, sets up to domestic photovoltaic power plant, provides clean energy for the family. The usual photovoltaic charger power for these photovoltaic power plants is typically between 10kW and is connected to the public grid through a 220/380V voltage class. The device can meet the daily electricity demand of families, and can sell the surplus electricity to the national power grid under the condition of surplus electricity, thereby realizing the reutilization of energy and economic benefit. At present, household energy storage schemes suitable for villa and other scenes are relatively mature. In this scheme, photovoltaic electricity is preferentially supplied to household loads, and after the household electricity demand is met, residual electricity can be used for charging the battery. When the battery is also full, the excess power is fed back to the grid. This scheme has a variety of modes of operation, such as a general mode, a standby mode, and an economy mode. In the general mode, photovoltaic electricity is preferentially supplied to a load, residual electricity charges a battery, and finally, abundant electricity quantity can be fed back to a power grid. In the standby mode, the power of the energy storage battery is only used under the condition of power failure of the power grid, namely, in the power failure mode, the energy storage battery only supplies power to the household appliances. Under the economy mode, the user can set charge and discharge time, for example, the battery is charged at night and discharged in daytime, so that valley peak use is realized, and the electric charge is saved. However, the core components of the current home energy storage solution include lithium batteries and energy storage inverters, which are economically costly, and for home users who own electric yachts, they are typically self-contained batteries and bi-directional OBCs (On-Board chargers, which are understood herein to be devices with bi-directional charge and discharge capabilities). These batteries and OBCs can provide a new idea for a home energy storage solution, namely to utilize batteries and bi-directional OBCs on yachts to reduce the cost of home energy storage. In addition, when the yacht is in the island service area, the scheme can also provide power support for the island service area, so that the application scene is further widened. In summary, the existing household energy storage scheme has achieved a certain result in technology and application, but still has the problem of high cost. For home users with electric yachts, how to utilize batteries and bi-directional OBCs on yachts to reduce home energy storage costs is a challenge.
