Request to suggest power line communication development kit and software

Other Parts Discussed in Thread: C2000WARE, AFE031, TIDA-060001, LAUNCHXL-F28069M

Respected sir,

I have to use powerline communication in my design. I have searched for the TI's PLC kit on TI site,

and I have found the TMDSPLCKIT-V3 kit. But this kit is out of stock, rather this is no longer manufactured.

Now I am facing the difficulty that which PLC kit should I use? Please suggest the PLC kit and also which software

should be used for that respective kit.

Regards

Nisha

    Hi Nisha,

    The owner of PLC is out-of-office today. He will get back to you as soon as he returns. Thanks for your patience!

    Nisha,

    We have removed the eMETER based PLC kits from TI.com; we are no longer developing new solns for the eMETER/standalone Power Line Communications market.

    However, we do have a low cost PLC implementation based on FSK physical layer supported in C2000 devices that can be integrated with other system functions.

    You can read about the concept and data rate here, the MAC is based on SunSpec, but can be adapted to suit your end equipment needs

    http://www.ti.com/lit/an/sprac94b/sprac94b.pdf

    If this will meet your system requirements here are the components you will need:

    LAUNCHXL-F28379D launchpad

    TIDA-060001

    C2000Ware  C:\ti\c2000\C2000Ware_1_00_04_00\device_support\f2837xd\examples\cpu1\boostxl_afe031_f28379d_xxxxx

    Best,

    Respected sir,
    I want to design the DC charger for electric vehicle. In that design i want to use the power line communication. will the above design is suitable for my case or not ?
    Also I want to ask that TIDA-060001 is the reference design and not available for sale, so what should I do? I have no idea how to design the board using AFE031. Please help me out.

    Regards

    Nisha,

    It really depends on the system needs for the PLC in the DC Charger if this will be suitable or not.  This method can work over AC or DC(i.e. Charger to the Grid or Charger to the EV), but the native datarate is ~200bps.  As I said, we have provided the source code, such that it could be modified to speed this up a bit.

    I would check the charging infrastructure you are building around for their requirements on speed and/or protocol type:

    CCS: https://www.charinev.org/ccs-at-a-glance/what-is-the-ccs/

    CHAdeMO: https://www.chademo.com/    

    For charger to Grid, it is most likely up to the utility company of that region.

    We also have a reference design targeted at DC (level 3) Chargers here: http://www.ti.com/tool/tidm-1000  This is also based on the F28379D, so if the BW requirements are met with the above it would be a very straightforward addition.

    Regarding the comments of TIDA-060001 being design only, all the applicable BOM/schematics/layout files are provided such that customers can make a physical design with their PCB vendor of choice.

    Respected sir,
    Thank you for your reply. I will proceed accordingly. You mentioned that you have provided the source code for this.
    Where would I found that code ?

    Nisha,
    The examples for Rx and Tx are included in the C2000Ware download I referenced a few post up. The only source that is not provided is that of the Rx calculations/math, which are held in a library. Based on you analysis of how the current protocol is working, if you feel that is not sufficient for your application then you are welcome to request the source for the Rx, a URL is contained in the application note for doing so.

    Respected Sir,

    In the TIDA-060001 TI's reference design LAUNCHXL- F28379D has been used. Instead of this can I use LAUNCHXL-F28069M ?
    Also the source codes for AFE031 using F28379D are available in C2000Ware but the same are unavailable for F28069. Can I get those codes ?

    Regards

    Nisha,

    Currently the FW is only written for the F2837xx devices as you mention.  However, it should be fairly straightforward to migrate it to the F2806x device you mention with the following in mind.  I'm also going to add another device, the F28004x since it also meets the requirements.  A LaunchPad featuring the F280049C device should be on TI.com around the middle of this quarter(July-Sept)

    CPU Clock Speed: the SPI data rate and PWM timings will need to be adjusted:

    F28379D = 200 MHz

    F2806x = 90MHz

    F28004x = 100MHz

    In terms of HW signals(SPI/PWM/ADC) the use of the LAUNCHXL-F28069M will work although there might be some GPIO changes/ADC input changes needed in the code. i.e. SPITX is on a different GPIO on the different devices.

    There shouldn't be an issue with the algos, as all of these three MCUs have the VCU (Viterbi Accelerator) which is used in the Rx portion of the FW.

    Let me know if you have other questions/concerns.

    Respected sir,

    Can you please tell us that OCPP Protocol (Open Charge Point Protocol) is supported by AFE031 or not?
    Can I implement that protocol using power line communication IC ? I have searched for this but I did'n get the actual answer.

    Regards,

    Nisha

    Nisha,
    I took a quick look at the OCPP specs, but I cannot find any Physical layer(PHY) info contained in them. They largely are focused on the MAC layer and above. With that said, the concentration of this spec is looking at the comms between the charger and the EV or the CSMS and the charger. In my experience with the comms from charger to EVSE the trend is to use Wideband PLC, which would not be supported by the AFE031. Furthermore, TI does not have a Wideband PLC chipset/offereing at this time.

    Best,
