I’ve got a couple of general Qs from a customer regarding BQTesla 150 solution:
note: board = transmitter (like PowerMat)
- What is the efficiency of charging? Is it really 70% for BQTesla 150 solution?
- Can you put more devices on one board? If so, I assume that the board won’t be able to provide the same current like for single device. Is there any formula how to calculate current losses if there are more devices on the board.
- Can the board communicate w/ more than one device lying on board?
- Is this wireless charging solution standalone (so that there is no need to attached MCU) Can send and receive data about charging status and conditions? What’s the communication protocol between transmitter and receiver?
- Customer doesn’t have resources to create these antennas for transmitting and receiving. Do we have 3rd parties who can help them to design it?
- Do we have reference design for transmitter and receiver – incl. layout that they can just copy?
- Who large that board can be.
Thank you.
