Hello there all you electrified downstaters, retiree McCorkle checking in from the NY hinterlands (Middleburgh).  Glad to see some charging stations are trickling in at the lab!

Mary, if I get this right, that your rate is thirteen cents per kWh, I suggest selling folks on the miles per dollar you get, or better yet, equivalent in gas costs.  For example, I get between 3 and 4 miles/kWh on my 2018 Volt, depending on temperature, terrain, etc.  Not sure what gas prices are down there, but taking the national average of 3.4 $/gallon, and 3.5 miles/kWh, one gets (3.4 / 0.13) * 3.5 = 92 miles for the cost of one gallon.

Average ICE mpg in the US is what, 22?  25?

interesting that 92 / 25 = 3.7 is not all that far off from the Carnot cycle waste heat loss ratio in ICE engines, isn't it?

Dear Gene and EV Users,

 

Great news on more chargers – I haven’t been using the lab chargers as much in the last couple of months since I got a L2 at home since the super off-peak rates from PSEGLI are around $13c/kwh.

 

I have some colleagues who are considering an EV/PHEV but due to lack of inventory at local dealerships cannot get a test drive, would some of the EV owners at BNL be willing to give tours or test drives of their vehicles? If so can I direct them to send email  this list if they are interested in a particular car? Maybe we could also try to organize a showcase day when it gets warmer.

Hi,  EV users

 

In addition to forwarding to this list this note from the administrator of the Lab's charging program and the message it conveys about respecting other users and their access to the charging stations, I want to highlight two items:

 

1) If it is inconvenient for you to leave work to move your vehicle to/from a charging station, then the Level 1 charging option may indeed be a better match for your situation. I think some people believe the Level 1 charging program to be expensive because of its one-price-for-all arrangement, but if it used al day for at least 2-3 days of each week, then it is actually less expensive than the Level 2 charging (which is roughly ~$0.19/kWh). You can adjust these numbers as you like, but roughly you get...

 

$17.56 / [(1.2 kW) x (8 hours/day) x (2.5 days/week) x (4 weeks/month)] = ~$0.18kWh

(and you might draw higher than 1.2 kW or use it for more hours)

 

2) The news of an effort to bring additional charging stations is a big deal - I look forward to the continued program growth! Please keep in mind that this growth is also likely include charging for Labratory-owned vehicles, and that those vehicles would likely have priority.  But given how difficult it has been to grow the program over the years, we should welcome what we can get!

 

Thanks,

-Gene

Hello EV Users,

 

Thank you for signing up and utilizing our Level 2 charging stations onsite! It has been noted that some users stay connected all day or well past the time their vehicle is fully charged. While it is very rewarding to see that the chargers are encouraging acquisitions of more electric vehicles, it also increases the difficulty for finding an open station to charge. Please be kind to your fellow EV neighbors. When vehicle charging is complete, an alert is sent by ChargePoint. Kindly move your vehicle at that time so it is available for others to utilize.  We are in the process of getting more Level 2 charging stations installed to better meet the demand.

 

If all level 2 charging ports are taken, don’t hesitate to sign up for the Level 1 charging sites and charge there.  Go to BNL | Guest Services | Electric Vehicle Charging Program< to learn more!

 

 

 

All the best,

 

Amanda Kuzujian
