    anyone else charging their PIP with a blink L2 EVSE?

    i'm finding that my blink keeps crashing over and over again but i can't say it's due to the prius. it might just be on the ... blink again (har har)

    also the prius reports that the charging power is "only" 1.9KW. it's probably a FAQ but is that the proper on-board charger capacity? i think the blink can deliver 3.6KW max.

    We are charging our PIP with the Blink we got from the EV Project for our LEAF. We haven't had any issues. We typically use the PIP Charging Timer to start charging at 5am. Occasionally we charge immediately if we are going out again on the same day. We don't use any settings on the Blink.

    me neither, the blink is set to always on and the timers are set in the leaf.

    after a few crashes the blink seems to have come up.

    anyone know if the 1.9KW charge rate is normal?

    The charge power is limited by the Prius Plug-in's charger. It takes about 3kWh of energy to charge the battery, so 3kWh/1.9kW = 1.6 hours to fully charge, which is consistent with the ~1.5 hours that Toyota says it takes to charge with an L2 EVSE.

    so the reported 4.4kwh battery capacity is the "raw" capacity that Toyota never actually fully uses, per their 80-20 (or thereabouts) battery management?

    4.4 kWh is the full battery capacity. It takes about ~3.2-3.3 kWh to charge the battery using 120V based on measurements with a Kill-a-Watt power meter. With ~85% charging efficiency, that means the actual usable capacity is ~2.7 kWh. I don't know what the lower and upper SOC ranges are, but 20-80% sounds reasonable.

    Someone has already measured the EV SoC range (I forget who)
    Low is 25%
    Hight is 85.1%

    [Added:] 85.1 % came from here.

    pfile, has your Blink been updated to the new firmware release (2.0.20120112 / E1.10)? Mine was updated around the beginning of February, and it has been more stable since then. Our PiP isn't here yet (this week!), so I haven't had the opportunity to charge it with the Blink yet.
