The system and vehicle can reduce costs and improve stability.

Description

Technical field [0001] The present invention relates to the field of vehicle technology, and more particularly to a vehicle-in-vehicle charger system, and a vehicle having the vehicle charger system. Background technique [0002] figure 1 It is a circuit diagram of a car charger system in the related art that is connected to the grid and the other end is connected to the battery pack, including Part1 'and Part 2' two-stage circuits. When charging is charged, Part1 'achieves AC-DC conversion and power factor correction, output DC voltage. Part2 'is a DC-DC converter, and the output is suitable for charging the battery pack. For this system, in order to provide a smooth input DC voltage, Part1 'and Part 2' require a large capacity of electrolytic capacitance C1 ', increase the volume and cost of the system, and the electrolytic capacitance C1' is a life, and the earthquake shock Question, the reliability of the system is unfavorable. Inventive content [0003] The present inventi...
