Combined with the characteristics of the traditional two lithium batteries on-board charger, the lithium battery Single-stage on-board charger was developed for electric vehicles, it used UCC28070 as system control core and MC9S08DZ60 as system monitoring and data transmission control core, control algorithm was developed, such as constant voltage, constant current and charging process, control circuit of the power transform was designed. Prototype experimental results showed that control of the charging process, data transmission, monitoring and protection functions of the on-board charger were achieved and high power factor and efficiency was obtained.
