System description
The wireless charger system consists of two main assemblies:
1. The WPU: Wireless Primary Unit (transmitter, TX)
a. WPB (Wireless Primary Box) connected to AC
The WPU is typically installed on the wall of the infrastructure.
2. The WSU: Wireless Secondary Unit (receiver, RX)
b. WSB (Wireless Secondary Box) that produces a DC output that is typically used to charge a
battery. The output the WSB produces can be controlled via CAN bus, or via inbuilt charging
The WSU is typically installed on moving equipment containing a battery, such as an AGV or pallet
jack. However the wireless charging system can be used in other applications where there is a
need to transfer power over an air gap.
