  • Page 1 LD Wireless Charging Technical Guide LD-60 LD-90 LD-250 25230-000 A...
  • Page 2 20452-700. Disclaimer The wireless charging system is not an OMRON product. As a result, it is the responsibility of the system integrator (or the end user) to determine the appropriateness of any wireless charging system, perform the implementation, and ensure its safe use.
  • Page 3 Cybersecurity To maintain the security and reliability of the system, a robust cybersecurity defense program should be implemented, which may include some or all of the following: Anti-virus protection • Install the latest commercial-quality anti-virus software on the computer connected to the control system and keep the software and virus definitions up-to-date.
  • Page 4 • When constructing network infrastructure, communication failure may occur due to cable disconnection or the influence of unauthorized network equipment. • Take adequate measures, such as restricting physical access to network devices, by means such as locking the installation area. •...

Disclaimer Information in this document is provided solely as a reference. OMRON does not guarantee the suitability of this wireless charging implementation for any particular purpose.
  • Page 8 2 LD Wireless Charging Reference Design This section contains information about the following: • Prohibited LD battery connections • Allowed LD Core connections Wiring details • • Battery characteristics and Wiferion settings • Wiferion hardware alignment and installation 2.1 Anatomy of the LD Battery and Prohibited Actions The LD battery pack is known as a split path battery pack, containing two separate current paths for charge and discharge current.
  • Page 9 battery’s charge path (but not the discharge path). More information is provided in Section 2.3 LD Battery Interface Circuit. The circuit schematic and wiring in this document ensure that only the wireless charging or contact charging plug can be physically connected to the CHARGE port at one time (not both). Please refer to Section 2.4 Wiring Details and Section 2.4.2 Required Detailed Wiring Schematic and Drawing for more information.
  • Page 10 2.2 Charge FET (Field-Effect Transistor) Manipulation Modern lithium-ion battery chargers require battery voltage to be applied to the charger’s connection terminals before allowing charging current to flow. The Wiferion system follows this paradigm. The LD battery pack was designed for a custom charger that required the opposite. In other words, the battery required the charger to present its voltage to the battery first before charging could take place.
  • Page 11 The image below shows where the power to supply the interface circuit comes from (USER PWR port on the Core). The net in red (SW_VBAT_OUT1) should be used to present a voltage of >21 V at the charge net which is a part of the interface circuit. The net in blue (SW_VBAT_OUT2) provides power to the Wiferion ME (EXT.
  • Page 12 2.4 Wiring Details This section contains details about the following: • Required cable for connection from LD Core to Wiferion ME Unit Wiring schematics and drawings for: • o ME Unit o Battery interface circuit o Block diagram o WC-H1, -H2, -H3 and -H4 cables 2.4.1 Connection From Core to Wiferion Mobile Electronics (ME) Unit To create the complete cable (WC-H1) shown in Section 2.4.2 Required Detailed Wiring Schematic and Drawing, you must use this off-the-shelf cable assembly, Molex PN: 0369240210 (shown below).
  • Page 13 2.4.2 Required Detailed Wiring Schematic and Drawing...
  • Page 17 The battery pack has a nominal resting voltage of 25.6 V. The BlueConfig Software settings that OMRON used in this development project are shown in the table below. For more instructions on how to configure these settings in BlueConfig Software, refer to Wiferion Software and Configuration Manual (Document No: KD100612).
  • Page 18 2.6 Alignment and Installation of Mobile and Stationary Unit The stationary coil and the mobile coil must be parallel to each other where their IrDa interfaces are aligned and facing each other. The optimum gap between the stationary coil and the mobile coil is 15 to 40 mm as stated in Specification for etaLINK 3000 on PULS Wiferion website.
  • Page 19 More information regarding installing and assembling the mobile and stationary units can be found in Wireless Charging System etaLINK 3000 Operating Instruction Manual (Document No.: KD 100801). Application Guideline The picture above is a reference design for explaining the concept of interference. In some installations, there have been reports that the infrared (IR) sensors on the Wiferion coils interact with lasers on the AMR.
  • Page 20 3 LD Battery Firmware Change To accommodate reliable wireless charging using Wiferion, OMRON has implemented the following two firmware changes to the LD battery (shown in the table below). It is required to update the firmware of the battery (PN: 20542-700) if the revision is older than AC. See Application Guideline in this section for more details.
  • Page 21 4. Successful complete bootup of the AMR after the restart will prove that the firmware update is completed. ARAM logs will also have traces of the update being successful. 4 Software Settings and Configuration This section provides guidance on a method to control the user power using the peripheral power output feature.
  • Page 22 • Type: The triggers for the output. This should be set to custom. Once the above configuration is set, it can then be controlled in two ways: Either through ARCL commands or through MobilePlanner tasks, as mentioned below. Toggling the power inside a macro using a MobilePlanner task is simpler compared to the ARCL command method.
  • Page 23 Application Guideline For opportunity charging, it is recommended to use the engage task (requires enable in Configuration tab) under the goal so that the AMR is prevented from rotating when at the charger. You must also use customOutputOn and customOutputOff to properly toggle the I/Os (SW_VBAT_OUT1 and SW_VBAT_OUT2).
  • Page 24 Application Guideline To start charging reliably for docked state/long-term/balancing charging, it is required to trigger the I/Os in the sequence shown in the below figure. These are some key points to note: • Before moving towards the target, make sure both SW_VBAT_OUT1 and SW_VBAT_OUT2 are off.

  • Page 26 This feature disables functionality of the AMR to actively check and switch to Docked state when it starts receiving a charge. Advantages: • This prevents the AMR from switching to Docked state when it receives a charge in each wireless charger/goal. This will allow the AMR to continue with the jobs without any interruptions.
  • Page 27 For warranty inquiries of wireless charging components, please contact each component’s customer support. 4. As part of its standard warranty disposition process, Omron retains the right to request shipment of suspected AMR failed components back to the factory for detailed analysis. AMR damage due to improper construction, connection, usage, and/or environment remains excluded from AMR warranty.
