EVA I

Evaluation tool for development of WPT transmitter designs up to 15 W

Developed by nok9, sole provider of compliance and reference tools for QI (BPP & EPP)

___________

Ideal development platform for WPT transmitters up to 15W

___________

Enables evaluation of designs and operating points in different WPT solutions

___________

Fully compliant with the WPC Power Class 0 specification

___________

Modular design for flexibility and scalability

SIMPLE AND SLEEK

EVA I is an ideal tool kit for rapid prototyping and reliable comparison of different designs and prototype solutions. Developers can utilize EVA I for the evaluation of their design, without the need to develop counterpart products themselves. A company developing receivers or transmitters for Power Class 0 applications can use the EVA I to evaluate the coupling, losses and operating points of their design. Equally important for research and development, EVA I serves as a dynamic and affordable evaluation tool for the analysis of system operations and benchmark of a receiver or transmitter module and coupling with different designs. EVA I is designed to be simple and sleek, easily connected to a computer or laptop through a USB port, thereby enabling full firsthand evaluation of different designs in a realistic use case scenario. EVA I comes in two stand-alone variants: EVA I BST (Base Station Tester) for testing transmitters and EVA I MDT (Mobile Device Tester) for testing receivers.

PROBLEM STATEMENT

Evaluation and benchmark is critical for the initial stage of product development, in order to select the best possible designs and components. However the ability to properly evaluate a product depends on access to reliable reference counter parts.

  • Commercial samples are usually accessible but often lacks the proper control and validation of measurements
  • Access to compliance test tools are costly and time critical

USER

The EVA I systems are ideal evaluation tools for developers and designers of WPT transmitters up to 15 W, during early development stages:

  • Evaluate prototypes with focus on Tx/Rx communication, (voltage, current, frequency), coupling factor and efficiency
  • Compare different WPT receiver or transmitter solutions and designs
  • Simulate different receiver or transmitter designs

EVA I BST

EVA I BST (Base Station Tester) is an evaluation platform for WPT transmitters (PTx) development, designed to support the WPC Qi standard.

The EVA I BST converts the AC input from any connected receiver coil to a DC output. Values are measured and presented in the GUI, through the USB connection to any external laptop. Operating parameters set in the GUI are interpreted by the EVA I BST unit and passed on through the EVA I TPR.

HARDWARE

__________________

The EVA I BST is a portable and modular platform that can be expanded with both HW and SW upgrades, purchased separately. The Starter Kit consists of a Control Unit and one TPR (Test Power Receiver), which serve as the PRx coil and placed on top of the PTx Device Under Test (DUT). Additional upgrades of HW include FOD kit and Sniffer probe.

CONTROL UNIT

The main control and processing unit. It contains the logical elements, measurement boards and electronics. When connected to a separate host computer, such as a PC, a powerful and use- friendly GUI enables configuration settings of parameters and use cases to then provide real time data collection and processing of test results.

EVA I TPR

The power transfer coil and the component that is coupled with the device under test (DUT), e.g. the transmitter. Through the EVA I TPR the electromagnetic signal is converted to electrical signals. A variety of TPRs are available, matching all reference designs defined in the Qi specification. The standard connectors also allow for proprietary coils to be connected directly to the EVA I BST unit.

_________________

The state of the art Graphical User Inteface is similar to other nok9 CATS tools (reference test equipment of WPC). Operating and real time measurements are presented to the user both in numerical values and graphical status bars, while the packet log displays communication as sent and intepreted by the tool. Utalizing graphical icons and visual indicators, the GUI provides real-time control over the systems operating parameters, allowing the user to interact with any electronic parameter and setting.

The GUI allows for full control of the tool, acting as a PRx (Qi receiver), while providing the user with live presentation of direct readouts of both communication log and key parameter measurement values.
