Electric Vehicles (EVs) as one alternative of clean transportation now has a growing market. To enhance the ecosystem of the EVs we must reduce dependencies on limited number of public batteries swapping stations or public battery charging station. This research aims to create a switched-mode power supply that specific to charge EVs battery using households electricity power especially in Indonesia, which is commonly limited to 900VA. Since electric motorcycle commonly using 80V/20Ah battery this charger design must follow the maximum rated voltage and current of the LiPo batteries. To be more specific our charger equipped with active power factor correction rectifier, with efficiency >97% and power factor >99%, and LLC dc-dc converter, with efficiency >90%, to convert input voltage 220VAC (rms) into output voltage 80VDC. The charger also designed to be deliver 800W power into the batteries, so it will not surpassed the limited household power
