Said charging device (2) includes: a first conversion module (3); a second conversion module (4); and a means (6) for controlling the first conversion module (3). The first conversion module (3) is suitable for converting an input AC current into an intermediate current and supplying said intermediate current to the second conversion module (4). The second conversion module (4) is suitable for converting the intermediate current into an output current and supplying said output current to the battery (5). The intermediate current is direct current, and the output current is also direct current. The controlling means (6) is suitable for adjusting the voltage of the intermediate current on the basis of operating parameters of the second conversion module (3)."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Vehicle battery external loading device including an AC/DC converter having a resonant insulated stage","description":"The invention relates to a device (2) for charging a motor-driven device battery (5).
