Hi Lawrence, My interpretation of Bruce's comments were that he liked you to disclose what your relation with EVRUS is - are you employee, investor or not financially tied but just a happy user, that you are posting about them regularly and appear to have inside information? This clarity will help other EV'ers judge better how to interpret your posts about EVRUS and may have impact on how you can post about that company, as it is generally frowned upon if an employee or financially interested party generates promotional posts on this list unasked. Most manufacturers/business owners I see on this list wait till they are asked about their product or may jump in when they have a very relevant solution for the question that someone posted on here, but they need to be modest about the amount of self-promotion, so that is what I saw in Bruce's post as a question to you to disclose that relation.
BTW, I am impressed that they can install fast chargers for such an affordable cost and I agree that for most cars (read: Leaf type batteries) a charging speed of about 25kW is sufficient. I drove to a 44kW Fast Charger last month to see how that worked and record the response from my Leaf's battery pack while charging and I arrived with less than 40% real SoC on LeafSpy, the Leaf indicated that I would barely make the trip back home if somehow it would not work but everything worked fine, LeafSpy showed 110 Amps into the pack and only a few minutes later the SoC had already risen to around 50% when the first cells started hitting the 4.115V limit that the Leaf BMS maintains and the current started throttling back. About 5 mins into the charging session the current was at 86A so this is 34kW, two minutes later it was 75A so it was already below 30kW (max pack voltage 395V) and it continued to drop until a half hour later the pack arrived above 88% real SoC on LeafSpy and the charging session automatically terminated. With a 25kW charger, the max charging current is limited to 25,000W / 395V = 63A for a Leaf. This will make the initial part of the session about 1.7 times as long, but since the CHAdeMO charger that I saw starts being throttled by my Leaf's BMS pretty soon, I agree that the charging time will only be impacts by about 10 mins (depending how deep you discharged). It is the nature of the beast and that is a simple matter of Physics so a different charging station cannot suddenly charge the Leaf in a much shorter time because it is not the charger but the Leaf battery and BMS protection that limits the charging rate and therefor determines the time. Do let us know what kind of interest you have in EVRUS!

Before EVRUS who scrounged together grants and an affordable 25kw charger there was no way to drive from Sacramento;/San Francisco/NorCAL on the Interstate 5 Freeway. As far as charging time our chargers take 10 minutes longer than the 40kw units....BTW There is an NRG charger that will charge you to 100 percent in Fairfield at the Nissan Dealer. Sweet unit but it cost half a million dollars...our units are under 30k installed. So you can sic the dog on me and not know or have an employee give the real scoop on new level three locations. BTW nobody is getting rich on this. Grants have funded most everything being done. Lately I have been driving the route from San Jose to Castaic. My boss doesn't want me to drive directly to Lebec from Lost Hills so I've been going to Bakersfield Nissan. I think this is a waste of time. The next time I go I'm going to insist on driving directly from Lost Hills to Lebec to see if it can be done for real. I did it the other way with a 38% remaining charge(Nissan Leaf 84 mile version)...but up the Grapevine is a different story. In my opinion the 101 between Salinas and Santa Barbara is the next Chademo area of need. There is already a CCS route on 101. CCS needs a route down the central valley as none exists now. So if you are going from Sacramento to LA you have to go through San Francisco and take the 101 to LA. The 99 has plenty of fast chargers(no CCS) but the 5 is quicker from San Francisco or San Jose. From my searches there is a need for some fast charging on the 5 North of Sacramento to Oregon...but sometimes the market must bear the burden...I'll talk to my boss. Maybe he can find a grant.
