Wherein, the distribution module 10 can be with filling the electric energy storage of electric pile output in auxiliary battery 60, for whole car control system provides the electric energy, and when the driving is at the in-process of traveling, power battery also can be for auxiliary battery charging to guarantee that auxiliary battery can normally provide the electric energy for whole car control system 80.

With continued reference to fig. 6, the cart further includes a second DC/DC converter 70;

the input end G1 of the second DC/DC converter 70 is electrically connected to the second end F2 of the auxiliary battery 60, the output end G2 of the second DC/DC converter 70 is electrically connected to the vehicle control system 80, and the second DC/DC converter 70 drives the vehicle control system 80 based on the electric energy output by the auxiliary battery 60.

Specifically, the second DC/DC converter 70 converts the voltage of the DC signal output by the auxiliary battery 60 into a voltage corresponding to the vehicle control system 80 to drive the vehicle control system 80, wherein the vehicle control system 80 may include a generator control system, a transmission control system, a vehicle body control system, and the like. In addition, the auxiliary battery 60 may also provide power for lights, gauges, and other body accessories.

With continued reference to fig. 6, the cart further includes a drive train 90; the drive train 90 is electrically connected to the third output a7 of the power distribution module.

The transmission system 90 is a power transmission device between the engine and the driving wheels of the vehicle, and is used for ensuring that the vehicle has the traction force required under various driving conditions. The power distribution module 10 may provide the power harvested by the charging post directly to the drive train.

Optionally, with continued reference to fig. 6, the power distribution module 10 further includes a first DC/DC converter 111;

the input end E1 of the first DC/DC converter 111 is electrically connected to the power battery 100, the output end E2 of the first DC/DC converter 111 is electrically connected to the transmission system 90, and the first DC/DC converter 111 drives the transmission system 90 based on the voltage output by the power battery 100.

Specifically, the first DC/DC converter 111 is disposed in the power distribution module 10, and when the power battery is charged, the power battery 100 provides electric energy to drive the vehicle to run through the transmission system 90. The voltage output from the power battery 100 is converted into a voltage matched with the transmission system 90 by the first DC/DC converter 111 to drive the transmission system 90.

The traveling crane provided by the embodiment includes the traveling crane charging system in the above embodiments, and therefore, the traveling crane provided by the embodiment also has the beneficial effects described in the above embodiments.
