ABSTRACT: In order to reduce the pollution caused by fuel vehicles to the environment, electric vehicles are becoming the means of transportation. The replacement of fuel vehicles by electric vehicles is a future trend. Based on practical requirements, a 120 kW direct current charger has been designed. Taking the MK60DN512 as the core controller, a direct current charger control system is designed and implemented. The overall solution of the direct current charger control system is designed. According to the functional requirements of the direct current charger, a system hardware platform is built based on embedded technology. The hardware mainly consists of MK60DN512 microcontroller, start/reset circuit, JTAG download/debugging circuit, clock circuit, minimum system power supply, output voltage sampling and signal conversion circuit, output current sampling and signal conversion circuit, AC relay control circuit and temperature detection circuit.
