The battery charging methods of unmanned forklift truck mainly include the following: wired charging and wireless charging. ‌

For wired charging, the AGV unmanned forklift truck should be parked in front of the specified charging pile, and the charging pile and AGV unmanned forklift truck should be connected by cable for charging. The advantages of wired charging are fast charging speed, high charging efficiency, and the power of the charging pile is also relatively large, which can meet the needs of high-power charging of AGV unmanned forklift trucks. However, wired charging requires the laying of cable lines, increasing the cost and complexity, while cable lines are also susceptible to wear and damage, increasing the difficulty and cost of maintenance ‌.

Wireless charging is a relatively new charging method, which realizes wireless charging by installing a receiver at the bottom of the AGV unmanned forklift truck and setting a transmitter in the charging area. The advantage of wireless charging is that it is flexible and does not require laying cable lines, which can save a lot of cost and time. At the same time, wireless charging can also achieve automatic charging, when the AGV unmanned forklift battery is below a certain value, it can automatically return to the charging area for charging. However, the charging efficiency of wireless charging is relatively low, the charging speed is also relatively slow, and the receiver and transmitter need to be set up in the AGV unmanned forklift and charging area, increasing the cost and complexity ‌.

In the specific charging steps, first check whether the charging device is working properly, and then connect the power cord of the charging device to the charging port of the forklift to ensure good contact. Then start the charging device, wait for the device to identify the forklift battery and set charging parameters, such as current, voltage, etc. After the start of charging, the temperature of the forklift battery and the output power of the charging device should be regularly checked to ensure the safety of charging. After charging, turn off the charging device and then disconnect the power cable ‌.
