I have the AeroVironment L2 charging station, ordered and installed as part of the Nissan LEAF reservation system. While it does charge my LEAF most of the time, there are some issues:
1- just ungodly expensive IMO for the wiring work, unit, etc. Total was just north of $4k. In our area, a permit and concomitant inspection are required.
2- there were no extra breakers on my panel so AV added a dedicated 40-amp circuit to a new breakout box outside by my SmartMeter. The power company confirmed my meter did not need an upgrade to support the additional power.
3- AV asked me if I wanted a shut-off breaker next to the charging station for convenience. I said yes and am very glad I did. See below.
4- I had the option of a 15- or 25-foot charging cable; I chose the shorter one as the station is close to where the front of my LEAF is parked. There might be value in the longer cable if you plan to charge outside your garage for whatever reason (more than one EV?). The cables are not interchangeable...they are hardwired into the station and are ordered as two different units.
5- the AV is a 30-amp unit, helpful for when I can afford that Tesla.
6- there is a red trouble light on the station front panel and it comes on during or after a charge about once a week, sometimes more often. AV tells me this is a safety feature of the device that recognizes a problem of some sort with the power coming into the unit. The ONLY way to reset this light is to cut power to the unit, hence my joy at having a circuit breaker next to the station. Power should be cut for enough time for all the internal capacitors to discharge, a few hours according to AV.
Downside: these trouble lights halt the charging function and I have awakened to an uncharged LEAF on several occasions. Although we do have the occasional power outage in Central Ohio, and more frequent power blips, none of the other electrical equipment with electronics in my home is bothered at all. After 8 months of this I am trying to get AV to replace the charging station but I've been put off for three weeks now due to "lack of technician availability."
Would I get this unit again? No. It has proven to be too annoying, expensive, and I have lost faith that I'll have a charged car in the a.m.
What would I do instead? Have a local electrician run and test the wiring, and add the Lowe's or Home Depot charging stations myself. Or at least I think I'll do that when that Tesla comes in.
