    quantified: how much power is used to charge an EV

    Trust me, I'm an engineer. I do already have LeafSpy; I principally use it to periodically gather SOH. I don't dispute its measurements might *marginally* narrow the widths of the peaks in the histogram, but it is also a major hassle to get it running and connected each time just to collect...

    quantified: how much power is used to charge an EV

    Say a driver wants to figure out the electrical power cost of making a trip using an EV. (Alternately, say they want to figure out the CO2 generated by the power grid to make the EV trip possible. Or, maybe they are trying to figure out how many solar panels are needed to offset their...

    lowest mileage LEAF battery fail ever?

    I'm someone who owns and has owned solid, dependable cars that are several decades old; replacement parts ensure vehicles continue working. So, the notion that it should be acceptable that a vehicle (particular a "green" one) needs to be thrown away after limited use really rubs me the wrong...

    lowest mileage LEAF battery fail ever?

    It was stated already, but the vehicle is configured for 80% max charge during my ownership. To elaborate, I start with 80% charge, make a trip, and then charge back to 80%. For a rare long journey, I override the timer to charge to 100% just prior to the trip, make the trip, and charge back...

    lowest mileage LEAF battery fail ever?

    Can anyone claim LEAF battery degradation at even fewer miles? I have a 2011 Nissan LEAF with 17,820 miles. The car is in nearly new condition, except for the battery. The GOM is at 7/12 bars; the SOH is 50.50%; it has 128 GIDs. Ten months ago, it had 16,392 miles, the SOH was 62.77%, and it...

    TCU Teardown

    Just in case someone is looking for the tech specs, I believe what you are referring to is on page 55 of the datasheet: https://www.hirose.com/product/document?clcode=&productname=&series=GT16&documenttype=Catalog&lang=en&documentid=D49384_en All the part numbers mentioned above and their...

    TCU Teardown

    The existing coax connectors are GT16C-1P-H on the PCB and GT16C-1S-HU on the cable side, right? It does look like Hirose already sells an SMA adapter; if I'm reading the Hirose datasheet right, I *think* GT16GP-HRMJ is the right part. However, the $167 price is high; moreover, it doesn't seem...

    TCU Teardown

    To gain some insight into the Nissan LEAF TCU, I bought a couple of cheap Nissan/Infiniti TCU (Telemetry) modules off eBay to take apart and examine. It seemed worthwhile to do a write-up here in case someone eventually looks for this kind of information in the future. NHTSA encouraged Nissan...
