Description

Technical Field

[0001] The present invention relates to a charging method and a charging device for a charging box of an unmanned charging vehicle, belonging to the technical field of unmanned charging vehicles. Background Art

[0002] At present, the energy of traditional fuel vehicles mainly relies on oil, and the shortage of oil and the serious environmental pollution caused by the exhaust gas emitted by fuel vehicles have made it increasingly urgent for humans to develop new green transportation tools. As a green transportation tool, electric vehicles not only have significant energy-saving effects, but also greatly improve the comprehensive utilization rate of energy, zero exhaust emissions, and obvious environmental benefits. With the continuous advancement of rechargeable battery manufacturing technology, electric vehicles will have the strength to compete with traditional fuel vehicles in the near future. At the same time, a prominent problem has arisen. Electric vehicles often cannot continue to drive because the power stored in the power battery is exhausted during driving because they have not reached the charging station. For this reason, the charging box with power is transported to the electric vehicle through an unmanned charging vehicle to recharge the electric vehicle, solving the problem of electric vehicles "laying down" on the road. However, when the power in the charging box is used up, it also needs to be recharged. In order to better realize unmanned and fully automated recharging, relevant equipment needs to be developed.

The cloud platform controls the lifting mechanism under the charging box to rise, so that the charging box and the unmanned charging vehicle are gradually separated. After that, the cloud platform sends a message to make the unmanned charging vehicle drive out. Then the cloud platform controls the lifting mechanism to descend, so that the charging female socket is inserted into the charging male socket to complete the pairing.
