Abstract

The invention provides an integrated vehicle-mounted charger system. The integrated vehicle-mounted charger system comprises a power factor correction control module, a high-voltage alternating-current side power switch module and a first winding of a transformer module which are connected in sequence, a second winding of the transformer module is respectively connected with a high-voltage direct-current side power switch module and a low-voltage power module through an input selection module; when the selection input module is in the first switching state, the integrated charger is controlledto form a first energy path between the mains supply and the power battery; and when the selection input module is in the second switching state, the integrated charger is controlled to form a secondenergy path between the power battery and the low-voltage battery. In this way, the total weight, size and cost of the vehicle-mounted charger and the vehicle-mounted DC / DC are reduced by fully utilizing the integration technology, the magnetic coupling problem in the magnetic integration scheme is avoided, and platformization of the product is easier to achieve.

Description

technical field [0001] The invention relates to the technical field of electric vehicle charging, in particular to an integrated vehicle charger system. Background technique [0002] As a clean energy vehicle, electric vehicles have the advantages of high energy utilization efficiency, energy saving, environmental protection and low noise, and become the main development direction of future transportation. Vehicle-mounted charger and vehicle-mounted DC / DC are important components of electric vehicles. The vehicle-mounted charger converts the mains power into direct current to charge the power battery pack, and the vehicle-mounted DC / DC converts the high-voltage direct current in the power battery pack into low-voltage direct current into low-voltage direct current. power supply to the load. In the past, the on-board charger and on-board DC / DC were discrete. In recent years, with the sharp drop in subsidies for electric vehicles, the pressure on the cost of complete vehicle...
