AGV truck – wireless charging solution
Analysis of current AGV charging pain points:
Status: AGV’s current charging methods are divided into two types, offline charging and online charging.
The pain points of offline charging are as follows:
There are two methods for offline charging,
The first method is to replace the AGV battery. The pain point is: it takes a long time to replace the battery, and it is troublesome to disassemble. It is necessary to reserve multiple batteries for charging turnover;
The second method is to use a plug at a fixed charging position, and reserve multiple AGVs for the waiting time for charging.
The pain points of online charging are as follows:
Online charging generally adopts the method of brush plate brush block for contact charging, and the charging contacts are worn out and need to be replaced regularly. There is a safety hazard due to the large charging current and possible sparks during charging. In addition, because the charging contacts are exposed parts, they cannot work normally in low temperature condensation, humidity, flammable and explosive environments.
The solution – using wireless charging technology:
As shown in the figure below, a wireless charging and charging platform (including a transmitter power supply and a wireless power supply transmitter) is set in the factory, and a wireless power supply receiver and a charging controller are built into the AGV trolley.
When the wireless charging receiving device in the car is aligned with the wireless charging transmitting device of the charging platform, the wireless charging of the AGV car can be realized;
Many wireless charging platforms are set up in the factory, and the AGV uses the fragmented time to charge randomly, which can make the AGV have power for 24 hours without having to replace the battery, and can also reduce the capacity and cost of the battery.
The advantages of wireless charging technology in AGV car:
1. There is no danger of sparks when charging
Unlike contact charging (metal contact contact charging) used in general charging systems, because we use “inductive charging” (wireless connection), there is no risk of electric shock or sparks; it can be used in low temperature and humidity. , flammable and explosive environments.
2. No need to set special charging area
The wireless charging system does not generate sparks in the charging area, so it is not necessary to set up any special charging area; increasing the space utilization rate of customers.
3. Reduce the labor cost of charging
You can set the charging area anywhere, and the AGV can automatically charge at the parking spot or within the operating area. It is no longer necessary to move the AGV specifically to the charging point and replace the AGV battery. Therefore, the use of human resources and the loss of machine downtime can be reduced, and the production efficiency can be improved.
4. AGV can run automatically for 24 hours!
Several charging points can be set up in the factory, and the AGV can make full use of the gap time for charging at any charging point, so that the AGV’s battery is always charged for 24 hours; so that the AGV can ensure that power is available at any time, thereby improving production efficiency.
5. Reduce battery backup!
Because the AGV will automatically charge when running through wireless charging. This allows for fewer battery backups and lower operating costs.
6. Long battery life!
The traditional charging, due to the particularity of the battery, repeats the rapid charging at a lower depth of discharge, which makes the aging of the plate faster and shortens the service life of the battery. Whereas wireless charging can automatically charge at every stopping point with relatively little depth of discharge (battery drain) and extended battery life.
7. High durability!
With inductive charging and protection of the charging point through coupling, there is no metal corrosion for better durability and longer life than typical contact charging (metal-to-metal contact).
