Household type intelligent composite charging and discharging pile regulated based on electricity price

Abstract

The invention discloses a household type intelligent composite charging and discharging pile regulated based on electricity price and belongs to the field of charging piles for electric cars. The household type intelligent composite charging and discharging pile comprises a housing, a control panel, a charging and discharging port, a charging and discharging driving module, a bidirectional alternating power distribution box, a bidirectional metering electricity meter, a main control module, a communication module, a power grid control center server and the like. Each composite charging and discharging pile exclusively belongs to a specific user for use; the characteristics that the utilization rate of the electric cars at night is low, the load of the power grid at night is at valley bottom and the allowance of a new-energy power generation system is relatively large are combined; electricity price lever and power grid regulation and control information are utilized for regulating theenergy of the power grid and consumption of new energy; and the functions such as repairing and maintenance of the electric cars are integrated. The household type intelligent composite charging and discharging pile has the advantages of being simple in structure, relatively low in cost, convenient to use, complete in function and capable of gaining considerable benefits on the premise of guaranteeing the maximum car use freedom degree and comfort level of a user, and providing favorable conditions for development and popularization of green and environment-friendly type automobiles.

Description

technical field [0001] The invention relates to a charging pile, in particular to a multifunctional intelligent composite charging and discharging pile which is installed separately and can perform charging and discharging operations. It belongs to the technical field of charging piles. Background technique [0002] As a green transportation tool with broad development prospects, electric vehicles are popularized at an extremely fast speed, and the future market prospects are also extremely huge. In the context of the global energy crisis and serious environmental crisis, charging piles and charging stations are the infrastructure for electric vehicles. The Chinese government actively promotes the application and development of new energy vehicles and their supporting facilities, which has very important social and economic benefits. benefit. [0003] At present, electric vehicles can only be charged at specially built public charging stations or parked in garages with cha...

Problems solved by technology

However, the charging station in this patent is public and centralized, and when it is necessary to purchase and sell electricity, it calls nearby electric vehicles to drive to the charging station.

Obviously, the ability to adjust the power grid is limited by the capacity of the charging station; it is difficult for users to spare time to stay at the V2G charging station for a period
