Abstract

The invention provides a charging circuit and a charging device. The circuit comprises a power supply input circuit whose input end is connected with a power grid, and a power adjustment circuit whoseinput end is connected with the output end of the power supply input circuit. The power adjustment circuit is used for adjusting the input power of a power supply. The circuit further comprises a transformer whose input end is connected with the output end of the power adjustment circuit, a power supply output circuit whose input end is connected with the output end of the transformer and outputend is connected with a charging interface, and a control circuit which is connected with the power adjustment circuit and the power supply input circuit and used for monitoring the input voltage of the power supply input circuit and controlling the power adjustment circuit to adjust the power supply input power according to the input voltage. According to the charging circuit provided by the invention, the power adjustment circuit and the control circuit are arranged; the control circuit monitors the input voltage; and at the same time the control circuit controls the power adjustment circuitto adjust the input power according to the monitored input voltage to adapt to the voltage fluctuations of the power grid to prevent current from exceeding rated current.

Description

technical field [0001] The invention relates to the technical field of new energy vehicles, in particular to a charging circuit and a charging device. Background technique [0002] Electric vehicles (Blade Electric Vehicles, referred to as BEV) are a type of new energy vehicles, which refer to vehicles that use vehicle batteries as power sources and motors to drive wheels. Compared with fuel vehicles, they have low emissions, energy saving, environmental protection, and low noise. Small, low cost and other advantages, it belongs to the green vehicle advocated by the contemporary era, and its sales volume is also increasing year by year. [0003] As we all know, charging is the first problem that electric vehicles need to face. In order to realize the charging of electric vehicles, charging devices such as charging piles are currently arranged on roads, basements, and residential areas to meet the charging needs of electric vehicles. When in use, charging devices such as cha...
