WiSnap + Elithion BMS

The Elithion Lithiumate BMS uses a serial cable to talk to the computer. That’s kind of a pain to see additional information that the SOC display doesn’t tell me. It is also nice to see... [read more]

PG&E Electric Rates and EVs

I never knew much about how I paid for electricity. I didn't know if we had certain hours that were peak or not. So, I called PG&E last week and they explained to me I was on the E1 rate. I told them I had an EV, and they suggested I go to E9 A or E9 B. They are listed here: http://pge.com/tariffs/ERS.SHTML#ERS

Like any good programmer, I decided to do my homework before blindly switching. It turns out that after I did the math, a PG&E representative told me they have a comparison spread sheet on their Plug-In Electric Vehicles page (here's a direct link to the excel spreadsheet). That page seems to lump a bunch of assumptions together about energy use, but I found that page to be quite accurate in its rough estimates.
