The present application discloses an integrated on-board charger circuit and a manufacturing method, and an integrated on-board charger. When the fixed terminal of the control unit is connected to the first selection terminal, the first processing circuit is used to transmit the first part of the energy of the commercial power to the power The battery (600), the second processing circuit is used to transmit the second part of the energy of the commercial power to the low-voltage battery (700); when the fixed terminal of the control unit is connected to the second selection terminal, the third processing circuit is used to transfer the power battery The first part of the energy of (600) is fed back to the power battery (600), and the fourth processing circuit is used to transmit the second part of the energy of the power battery (600) to the low-voltage battery (700). By transmitting the mains power to the power battery and the low-voltage battery, the power battery can transmit energy to the power battery and the low-voltage battery, so that the on-board charger can meet the diversified use needs in future scenarios.
Description
technical field [0001] The present application relates to the technical field of electric vehicle charging, and in particular, to an integrated on-board charger circuit and a manufacturing method, and an integrated on-board charger. Background technique [0002] In recent years, in order to protect the environment and reduce the use of non-renewable resources, new energy has been gradually introduced in the field of automobile manufacturing and application. Electric vehicles are the main force of new energy vehicles, and electric vehicles are further divided into pure electric vehicles, hybrid electric vehicles and fuel cell vehicles. As new energy vehicles gradually become an important development direction of the automotive industry in the future, on-board electronic equipment (such as DC / DC converters and integrated on-board chargers) is showing a trend of miniaturization, integration and high power density. At present, the integrated on-board charger circuit has realize...
