Dilong's efficient three in one vehicle power supply M64 series products effectively integrate on-board charger (OBC), DC/DC converter and high-voltage distribution unit (PDU), which is a high-performance integrated vehicle power supply tailored for electric vehicles by Dilong. This product is an intelligent and highly integrated 3 in 1 onboard charger, which includes a 6.6 kW OBC module, a 1.5 kW DC/DC module and a PDU module.
Dilong M64 series products adopt advanced all-digital control technology, PFC active power factor correction and LLC resonant frequency modulation technology, which have the characteristics of high efficiency, high power, small volume, reliable operation, wide input and output voltage range and zero pollution to the power grid. The charging method adopts automatic conversion of constant power, constant voltage and constant current, which effectively saves charging time and prolongs the service life of the vehicle battery. The communication control adopts CAN 2.0B communication protocol, which has the functions of intelligent charging, intelligent monitoring and fault alarm. At the same time, an independent auxiliary power supply is built in to supply power for the BMS battery management system.
This three in one on-board charger is designed by Dilong New Energy Technology Hebei Co. Ltd. for the charging and buck conversion of electric vehicle battery packs. Through efficient integration, it reduces the number of vehicle harness connectors and the trouble caused by the installation of split power supply, which can effectively save vehicle space.
Its various performance indexes have reached the international advanced level, and the water-cooling design makes the product run trouble-free for a longer time, reducing the natural defects and use risks due to the selection of fan cooling mode.
Product advantage:
- High power density, novel design scheme and low system cost;
- Small size, light weight and high integration;
- High performance index, high safety and reliability;
- Complete protection function, with the basic protection function of power supply;
- High working efficiency, with peak efficiency of 96%;
