The invention relates to the field of motor home high-voltage energy storage, in particular to a direct-current fast charging device for a motor home double-pack energy storage system and a control method of the direct-current fast charging device. The motor home double-pack energy storage system is charged through external power supply equipment, and the external power supply equipment comprises a new energy automobile direct-current charging pile; the motor home double-pack energy storage system comprises double high-voltage battery packs, an all-in-one controller, a direct-current quick charging pile and a direct-current quick charging device. Direct current output by the new energy automobile direct current charging pile efficiently charges the double-high-voltage battery pack through the direct current quick charging device. And the direct current output by the high-voltage battery pack is converted into 12V direct current and 220V alternating current through the all-in-one controller, so as to supply power to 12V direct current and 220V alternating current electric equipment. According to the direct-current fast charging device and the control method thereof, direct-current fast charging of the double packs can be effectively and reasonably controlled according to the devices of the motor home energy storage system and real-time working conditions, the charging efficiency is improved, the charging capacity of the double packs is improved, and the service life of the double packs is prolonged.
