Problems solved by technology

This power supply system can provide driving and control power for the AGV without a battery, but since there is no energy storage device, the entire running track needs to lay power cables, which not only increases the construction cost, but also reduces the flexibility of the route.

Embodiment 1

[0024] Such as figure 1 As shown, the charging device mainly includes a receiving device 1, a power supply device 2, an AGV system 3, and a wireless transmitting device not shown in the figure.

[0025] Wherein, the power supply device 2 mainly includes a charging terminal 21 , a lithium ion capacitor module 22 (ie, a LIC module), a battery management system (BMS) 23 , a regulated power supply 24 and a braking plate 25 . The lithium-ion capacitor module 22 is composed of several lithium-ion capacitor cells connected in series end to end. The positive pole of the lithium-ion capacitor module 22 is connected to the positive pole of the charging terminal 21, and the negative pole of the lithium-ion capacitor module 22 passes through the 300A fuse and the battery management system in turn. 23 is connected to the negative pole of the charging terminal 21 to form a charging closed circuit. The battery management system 23 is used to monitor signals such as voltage, current, tempera...

Abstract

The invention discloses a charging device of an automated guided vehicle (AGV). The charging device is composed of a power supply device (2) and an AGV system (3). The power supply device (2) includes a power supply closed loop for providing a stable voltage for the AGV system (3). A lithium-ion capacitor module group (22) and a battery management system (23) are connected in series and then are connected in parallel with a voltage-stabilizing power supply (24) to form the power supply closed loop; and the lithium-ion capacitor module group (22), the battery management system (23), and a charging terminal (21) can form a charging closed loop. Besides, the charging device also includes a receiving device (1) and a wireless transmitting device laid in an AGV preset track, wherein the receiving device (1) and the charging terminal (21) can form a closed loop; and the wireless transmitting device and the receiving device (1) are connected in a wireless power supply mode. In addition, the invention also discloses a charging method. According to the invention, an AGV can be charged rapidly on the premise that the vehicle is not stopped, so that the continuous production process of the vehicle is realized.

Description

technical field [0001] The invention relates to a charging device, in particular to a charging device for an AGV trolley and a charging method thereof. Background technique [0002] AGV (Automated Guided Vehicles) trolley is a transport vehicle equipped with an automatic guiding device that can travel along a prescribed guiding path. At present, the power unit of the AGV car is a rechargeable battery. When the AGV is running, the electric energy of the battery gradually decreases, so the AGV battery needs to be charged during the cycle operation. [0003] Traditional AGV trolley power units include lead-acid batteries, nickel-cadmium batteries or lithium-ion batteries. [0004] The internal resistance of lead-acid batteries and lithium-ion batteries is large, and it takes a long time to charge them as the power unit of the AGV car, which will cause the car to stagnate for a long time in the charging area, prompting production interruption and reducing work efficiency; nick...
