VRM series Vehicle charging pile Application: On-board DC charging of vehicles such as electric cars, taxis, engineering vehicles and coaches. Overview: VRM360 series is an intelligent on-board DC Vehicle charging pile promoted by SICON to meet market demands. It adopts advanced modular structure design concept and cutting-edge electronic circuit technology. It is internal vehicle charging module of electric cars, converts AC mains to DC power which can be used by electric car battery. Rectiﬁer module input is single-phase mains, output DC is 200VDC-450VDC / 250VDC-650VDC / 300VDC-750VDC, to meet demands of different voltage battery pack. Functions such as start-up self-detection, AC input over/under voltage protection output overload protection over temperature protection are inside the module. Active power factor calibration technology, DC-DC conversion technology, full digital DSP control are adopted. The DC-DC power circuit adopts alternating tri-level series resonance soft switch technology, the efﬁciency of which can reach 300 KHz, with high reliability, high availability, high maintainability and high efﬁciency. Feature: ● Wide input voltage range:90-264V, input surge protection design, single module power:3.3KW、6.0KW; ● Adopting DSP digital control technology, full digital control from input to output. ● Alternating series resonance soft switch technology decreases power device bearing capacity. ● Input harmonic<3%, input PF 0.99, system efﬁciency >95%. ● Ultra wide output voltage range: adjustable 250~420VDC, meets demands of varies voltage of battery pack. ● Low output DC ripple, no effect on battery life. ● Monitor equipped with standard CAN communication interface, easy to exchange data with external device; ● Protections such as over voltage protection, under voltage alarm at input side, over current, short circuit protection at output side. ● 13.8VDC auxiliary power, for BMS in car. Active power factor calibration rectiﬁe Input over-voltage, under-voltage protection Over temperature protection Output over-voltage, over-current and short circuit protection DC/DC converter Output protection Sampling feedback
