The present invention relates to a transformer for an on-board charger of an electric vehicle, the transformer being used as an on-board charger (10) of an electric vehicle for charging a high-voltage battery (30) of the electric vehicle with common AC power (220V AC) supplied from a charger (G) of an electric vehicle (V), the transformer comprising: a housing (110) in which an installation space (Sa) is formed; a cover (120) for opening and closing an installation space (Sa) of the housing (110); a flat-plate-type primary coil (130) which is built in the mounting space (Sa) of the housing (110) and receives power supplied from the charger side of the electric vehicle; and a plurality of flat-plate-type secondary coils (140) which are built in the mounting space (Sa) of the housing (110), and which independently generate an induced current from the primary coils (130) by means of magnetic field induction and output the induced current to a high-voltage battery, whereby the size can be reduced, the productivity of a product can be improved, and the price competitiveness of the product can be improved.

    本发明涉及电动汽车的车载充电器用变压器,作为将从电动汽车(V)的充电器(G)供应的常用交流电力(220V AC)向电动汽车的高压电池(30)充电的电动汽车的车载充电器(10),包括:外壳(110),其形成有装入空间(Sa);盖子(120),其用于开闭所述外壳(110)的装入空间(Sa);平板型的1次侧线圈(130),其在所述外壳(110)的装入空间(Sa)内置,接收从电动汽车的充电器侧提供的电力;平板型的多个2次侧线圈(140),其在所述外壳(110)的装入空间(Sa)内置,从所述1次侧线圈(130)分别独立地通过磁场感应生成感应电流,向高压电池输出,由此,具有如下益处:能够缩小尺寸,提高产品生产性,而提高产品的价格竞争力。
