Explosion-proof AGV (Automatic Guided Vehicle) compound system adopting double battery packs

The invention provides an anti-explosion AGV compound system adopting double battery packs. The compound system comprises a main battery power supply loop system, an auxiliary battery power supply loop system and an auxiliary battery charging system. When a positive voltage system of the main battery power supply loop system is established, a positive voltage control unit U3 controls a main loop contactor KM1 to be switched on, and a main battery BAT1 supplies power to a main control unit U2 and an equipment loop unit U1; according to the auxiliary battery power supply loop system, when the power supply voltage of an auxiliary battery BAT2 meets the requirement of a composite system, a positive voltage system is established, and a positive voltage control unit U3 controls a main loop contactor KM1 to be switched on; according to the auxiliary battery charging system, a positive voltage control unit U3 is connected with a main battery BAT1 and an auxiliary battery BAT2, battery parameters are read, when the au
