    Please refresh my old man memory. This is a BMS for a Gen-2 Prius?

    Can I get a high level description of what it does since the web page has gone dark?

    Hi Bob,

    Only works with second generation. The BMSplus module interconnects into the CanBus wires just before the battery ECU. It captures the HV Battery SoC message on the CanBus and changes the SoC value and then transmits back on the CanBus so that the Hybrid ECU gets the modified SoC message (higher SoC value) and as a result the Hybrid ECU will ask to use more HV battery and less ICE. That pretty much sums it up.

    How would someone display the can data from this. I have a 7" VGA Lilliput touchscreen that I am hoping to use. However I am wholly ignorant on hardware and programming .. .. I am unsure about CANVIEW

    It was done using mmbasic programming by Geoff (Geoff's Projects - Maximite Basic). Too complex for most people. You can read about it here - (My Duinomite Mega Canview V4 equivalent Project | PriusChat). I no longer have a Prius so I have forgotten it all.

    I had a closer look....the EAA PHEV website has some information as does Calcars......from my understanding if you have/had factory navigation with DVD player below driver seat then you had VGA capability . Gen 2 without factory navigation used a cable (modified) that connected to back of MFD and require a setup

    hello
    NortTexSalv04Prius,
    hybrid assistant
    is a very simple way to display Prius canbus info.
    a good odb2 dongle and a simple smartphone are only required.
    it's free and available from play-store

    my bms2 clone is working, I can see SOC modification according to bms2 on/off button
    when enable, SOC goes to 99% when power is asked.
    I still have to test if power relay is correctly drived in P4 off mode.
    the status led remain always on.

    You can use a Scangauge II. Or Torque Pro. Or a Canview.. You should see the HV battery all bars on your MDF light up all green when the SoC is 99%. Congratulations. Nice work.

    He
    Question
    When you can or have time can you post a working screen shot..?

    When I checked hybrid assistant Link ….the screenshots where like Prius C /Aqua and Yaris

    You mean a OBD2 dongle like the ELM knockoff you see listed on Ebay?
