Re: [EVDL] Charging adapter for J1772?
Noob question here. Isn't the EVSE's current capability part of the J1772 handshake? Even if there's no way to automatically throttle your EV charger, could you query the EVSE through the plug and dial down your charger to the appropriate query manually? Or at least use the EVSE signal to prevent your charger from attempting to draw too much and pop the breaker for the EVSE?

[EVDL] V2G for my grid tied solar?
I know there has been a lot of churn the last few years over Vehicle to Grid technology. I'm not sure how many people really want the utilities to take over their vehicle state of charge, so I'm not sure how viable the whole concept is. With my grid tied solar system my solar stops producing if the grid goes down. One way to prevent this is to have a battery backup system in place. That's usually an investment of at least several thousand dollars. I have two factory OEM PHEVs sitting in my driveway with significant battery packs. I also have a Juicebox 40 for charging which has some charging intelligence already built into it for their Juicenet program, but not really V2G. I feel like I am tantalizingly close to a great solution. So here is the question that I have. How far am I from being able to utilize my car batteries through the OEM port and an EVSE charger, to feed an inverter and keep my house alive and my solar producing during a power outage? Is this tech currently being developed, or is it still just a dream that my come true some day? BTW - I have lived in my house for 20+ years and rarely lose power, but "being prepared" is always on my agenda. I suspect that if I really want a solution within the next couple of years I will need to buy a separate battery for my solar system, or a generator... thanks Damon -- next part -- An HTML attachment was scrubbed...

I also have a Juicebox 40 for charging which has some charging intelligence already built into it for their Juicenet program, but not really V2G. I feel like I am tantalizingly close to a great solution. AFAIK, all car J1772 ports are inherently one way; they feed ac current to the onboard charger. One exception is Tesla where a single charge port either accesses the battery (at SuperChargers) or behaves exactly like a J1772 port. So, for home power from an EV, the chademo/combo port is a better candidate. The biggest problem seems to be that EV makers do not wish that to happen. This V2H problem is something I've been considering seriously for several months. I have three electric meters and I got a PowerWall installed on one last year. I am extremely happy with the PW but much less so with "Tesla Energy", the Tesla branch that deals with municipal and residential battery backups as well as PV. It seems Tesla does not wish to sell many PWs. Anyway, I've been looking at other microgrid alternatives and have not found anything compelling. Jack Rickard (EVTV) is offering some interesting stuff, though. I would like to have a cheap very minimal microgrid which functions like a PW. With the recent discussion of pulling up to 1kw out of any EV through the 12v DC-DC, I've become interested in trying to use an EV's 12v to add up to a kw to my imagined minimal microgrid. I've been experimenting trying to power an Enphase M215 from an EV 12v. I'm stepping up the voltage to 20-30 but have not had sucess. I do not understand MPPT and think that is the likely source of my trouble. A minimal microgrid would be limited in power but could supply more than a PW's worth of energy over night. So here is the question that I have. How far am I from being able to utilize my car batteries through the OEM port and an EVSE charger, to feed an inverter and keep my house alive and my solar producing during a power outage? Is this tech currently being developed, or is it still just a dream that my come true some day? Word is, that Tesla has the grid or gridtie inverter already built into the power electronics. We hope that that V2H capability will some day magically appear via a software update. I see it possible that a Tesla could back feed through a Tesla "Wall Connector". Wall Connectors can do up to 20kw so it should be possible to supply a house via that route. BTW - I have lived in my house for 20+ years and rarely lose power, but "being prepared" is always on my agenda. I suspect that if I really want a solution within the next couple of years I will need to buy a separate battery for my solar system, or a generator... My situation is that I have up to 100wkh per day from PV but need only about 20kwh. So, I am selling most of my PV energy to my utility. During the day, I am awash in power. When/if the grid goes down, most of that power will go to waste. I will hijack your thread and ask if anyone has microgrid suggestions or can give some guidance on using a gridtie inverter on not PV power. I'm very pleased you brought the topic up. Here is some discussion of augmenting a microgrid (or real grid) with EV 12v: https://teslamotorsclub.com/tmc/threads/audio-album-artwork-not-appearing.12635/ ___ UNSUBSCRIBE: http://www.evdl.org/help/index.html#usub ARCHIVE: http://www.evdl.org/archive/index.html INFO: http://lists.evdl.org/listinfo.cgi/ev-evdl.org Please discuss EV drag racing at NEDRA (http://groups.yahoo.com/group/NEDRA)
Re: [EVDL] L1/L2 EVSE for $189
Seems like only a few years ago, when EVSEs were all hardwired, came from big name industrial manufacturers and sported prices over $1000, I predicted it wouldn't be long before you could get them anywhere for under $200. Not many bought that idea. Now if we could only get that Moore's Law effect to work on batteries. Evolution has been pretty impressive, but I'm hoping solid state gives us a step change. We're overdue. We got an unexpected bump with the Tesla Switched Reluctance Motor breakthrough, and that one will benefit many more industries than EVs. I haven't been involved with EVs as long as some here, but I almost feel like I'm watching a child grow and mature. The future looks bright. It's gratifying to be part of it.

Re: [EVDL] V2G for my grid tied solar?
You already have what you need for continuous operation at night in the 1 kW class (refrigerator, well pump and lights, etc) See http://aprs.org/powerwheels.html But it assumes you have the Sunny Boy GT inverter with "secure" power when the grid goes down to charge your EV. $1500 Or if you are lucky to find a UPS of at least 1800W capacity to charge the car, and then you can drive that from batteries that you charge from voltage taps on y our DC array that match the input voltage of the UPS. But ONLY if you seriouisly know what you are doing and do not overcharge the intermediate battery., etc. Bob On Sun, Sep 1, 2019 at 12:28 PM Damon Henry via EV wrote: > I know there has been a lot of churn the last few years over Vehicle to > Grid technology.

Re: [EVDL] V2G for my grid tied solar?
Again, if you find a 72v UPS (6 12v batteries) then you can tap your arrays in groups of three and use that to provide the current to the UPS to dirive your car charger. Just 9 panels in 3 parallel strings of 90v will give maybe 20 amps (or the minimum needed to charge L1) But 12 panels (or about one string array) will give you plenty of current over more hours of the day. That's why I like string inverters beccause I have access to all the DC inputs and ground mount so I can get to them any time I want.

Re: [EVDL] ] *8/30-31 only: BuyNow $1.7k priced, Elf enclosed_e-trike SF-CA> needs battery
I own one and I have walked the hills in San Fran, you are not going to like it there. You will bust a gut trying to go up, and wish it was a car trying to slow and stop going down. I speak from experience as a long time cyclist and one who commuted 25 miles each way on an ELF. You had better be in shape if there is much distance or inclination. I maintained mine myself, but finding experience mech help willing to work on it will be non trivial. Earlier models had a power train that was troublesome. If the motor is hub mounted rather than as a mid drive, then there are durability issues. Not sure why you care about wheel diameter. It is not worth worrying about that, just pump them up hard. You buy it and you will find out why the price has taken a dive. Buy it for yourself, not for a wife or SO.

[EVDL] How2 slow-down lead-acid battery terminal corrosion
Yes, Vaseline! Its an EV old timer method that works. The 'quick and pretty' spray on types just do not last, and should not be used for a long term prevention. See 1min+18sec in this video https://www.youtube.com/watch?v=wZB8oKNDajA Yes its an ice video, & I do not agree totally with their methods. Nor do I in this video https://www.youtube.com/watch?v=UMzvqQGJGEc I do not spoil my tools with acid build up. I neutralize the acid first, then rinse & clean that up, before using my tools. This link yaks about acid build up https://no.co/blog/ultimate-guide-to-clean-and-remove-car-battery-corrosion ... https://www.google.com/search?q=lead+acid+gassing+acid+spray+corrosion I used the same type of anti-acid grease that jay posted, only I bought it in a tube size. Even on a 132VDC EV (22 6V wet-cell PbSO4) pack replacement, I never used much of the tube. I might be wiser to only buy what you need by going with Jay's approach of either several small packets for a pack change, or just 1 or 2 for only a few batteries. If you can't find these, here are some links: https://www.rvautoparts.com/09976-Permatex-Battery-Cleaner-For-Sealing-And-Coating-The-Terminals_p_374771.html Permatex Battery Cleaner For Sealing And Coating The Terminals Price: $1.04 (+shipping) https://www.walmart.com/ip/American-Grease-Stick-AGS-Battery-Terminal-Protector-Dielectric-Grease-Pouch-4-g/128539358 American Grease Stick (AGS) Battery Terminal Protector Dielectric Grease, Pouch, 4 g $1.19 Free delivery I would 1st be concerned as to why there is a build up. Is the pack old (on its last year of tired life) thus its voltages have changed, but the charger is still banging away like it is a new (higher voltage) pack? Could be the last equalizing charger-stage is on too long. Or was electrolyte spilled out of the cells because of over flow. Cells should never be 'topped off before charging. Each cell should only have enough 'distilled water' added to cover the plates before charging. Then once the battery is fully charged, distilled water is added to the ring at the hole for the cap. My approach to working the PbSO4 pack is to first put on old-clothes you don't mind allowing acid to eat holes into, wear rubber/kitchen gloves, and eye protection. Items you'll need are: baking soda, a cup to mix to with tap-water, paper-towels, a glass (windex) type glass cleaner, rubbing alcohol, and the tools to loosen & tighten the terminal clamps. With the ac cord unplugged from the EV, the pack power 'kill switch set to off, and all caps on their cells, I lightly hose down the tops of the batteries. Then make several cups of baking-soda solution (2tbs per cup of tap-water) to pour over the visible acid build up (to neutralize it). Let that bubble up, and set for a few minutes, until bubbling stops. then rinse off with tap-water. Repeat if acid-build up is very bad. Now that the acid level is much lower, use your tools to remove the terminal cables. Place each cable end with acid build up in a baking soda solution for several minutes (to neutralize the acid). Rinse & repeat if needed. I lightly spray the tops of the batteries with the glass cleaner (to remove road-grime contamination), and wipe down with a paper towel. With a new paper towel fold it in a pad, put alcohol on it, and use that to clean the cable ends and terminal sides that with make metal-to-metal contact with each other when joined back together (using your tools). An EV old timer said he put Vaseline on the terminals before you put the clams on (he was a EE). He said the tight frictional fit makes the cable end bite-into the terminal post (making metal-to-metal contact, despite the Vaseline) Im of a different mind-set that has worked well for over 15 years. I do not coat the cable end nor the terminal post, until after I have put the alcohol cleaned pieces together tightly. I then coat all surfaces of each post union (bottom and tops) with said anti-acid grease. With a clean paper towel folded as a 2 ply, I remove the caps and lay them out on the towel. With another clean paper towel, I gently wipe away any road grime still on the battery top that were held by the battery caps (being careful to wipe away from the holes in the battery). I then ensure each cell has enough 'distilled water' to cover the plates. Then check/clean the bottom of a cap with a clean paper towel before replacing the cap back onto the battery. Then I do a slow level-1 l1 charge overnight to fully charge the battery. Afterward, I again remove the caps in the same manner, and then fill with 'distilled-water' the now fully charged battery to its ring at the caps hole. Place the caps back on, check the cable tightness again, and again lightly glass cleaner spray the tops of the battery, wiping down with a paper towel. (btw, the glass cleaner is a mild alkaline solution, so it helps neutralize any residual acid, besides keeping the tops clean for when you show them to the public

Re: [EVDL] How2 slow-down lead-acid battery terminal corrosion
I use the baking soda treatment on the battery tops, too. You will be surprised at the acid on there. Sometimes it’s enough to create a circuit between the posts.
