Things are changing a little now, but in the early days the providers would require you to put a deposit into your charging account (like $25) and then charging sessions that were authenticated by their card would be subtracted from your account. When your amount got low, they would...

He spent a total of $2600 for the repair at the local Nissan dealership. The car stopped L2 charging at home. He didn't try it at any other sites or on a Chademo charger. He had it replaced without mentioning it to me; I would have helped him troubleshoot it a bit. After the OBC replacement...

I bought the Setec adapter and it didn't work on a Model S or a Model 3 at ANY of the three EA and EVgo stations I went to. Contacted them for a refund and they wanted me to start trying different firmware. I didn't want to, but I tried their new firmware. It didn't work either. 0%...

Utilities will require UL/NRTL testing as part of the interconnection process. The Wallbox folks can't really apply for UL/NRTL testing until they are done designing the product for North America (and the testing can take a while and cost a bit). As far as the price for testing, an OEM that...

Something like this? https://www.amazon.com/Lectron-Tesla-Charger-J1772-Adapter/dp/B07V7V2QT8?th=1

Just saw this from a few days ago....$89/month lease with about $1400 down. Not a bad deal.... https://cleantechnica.com/2021/08/05/nissan-slashes-price-of-base-leaf-to-28375-offers-89-lease-plan/?fbclid=IwAR33d70LOWipcDzD0RJJTQEJF4vyNvcsD5TqWKF9QP6gs8kytb0VUxN10w0

Do you live in a single family home? Those are usually fed with 240/120v. But if you live in a multi-family home such as a condo or apartment, those are usually fed at 208/120v. That could account for a slightly reduced power level...

Here is an example where Tesla wanted to install superchargers on a Pasadena city parking structure/lot and the only way they could get permission from the City of Pasadena was to provide $140K worth of infrastructure for the City to install their own fast charging stations...I think we'll see...

Riddle me this, group. Scenario: Electrify America site. Say it has 3 dispenser cabinets, and each cabinet has two nozzles. 2 of the 3 have dual CCS, even though only one car can be charged at one time. The third cabinet has a CCS nozzle and a Chademo nozzle. How would you count this site...

I work for the utility in San Diego. When people post about demand charges and how bad they are, I feel that they are missing an important fact that is not often discussed. The demand charges on commercial rates go hand-in-hand with much lower energy prices, on the order of 1/3 the price or...

Think of the frequency of the power system like a belt-driven table saw. When it is free running at a steady state, that equates to 60 Hz on a power system. When you shove a big piece of wood through the saw to cut it (similar to adding to the power system load), you can hear the motor on the...

Don't forget, the first bar is worth something like 15% and subsequent bars are worth about half that (if I'm remembering correctly). So it takes longer for the first bar to disappear than others...

Original battery after 7 years? Replacement time, if that's the case...

In that particular example (possible rolling blackouts), it isn't so much that grid upgrades are necessary as much as it is new generation resources are needed. Fossil plants have been retiring and the State is short of generation resources. Diablo Canyon will be retired in a few short years...

So maybe it was Ghosn all along who was the Chademo fan? :)
