Re: 12 kW chademo charging

[i]If I were to do that I'd start with a hefty resistor in series to limit the current. That's an excellent point. In a standard PV gridtie set up, the panels themselves are current the limiter. I guess one way is to add a panel in series to the Chamedo DC, without killing oneself first, to serve a...

Re: 12 kW chademo charging

so has any one yet to connect a grid-tie inverter to the Chamedo port ? even with the grid on, to see if it works ? Joes, Morningstar has a relatively new 600vdc charge controller: https://www.morningstarcorp.com/products/tristar-mppt-600v/ which you could rig up to your ground mounted PV to charge ...

Re: New Owner - Ben got an iMiEV - Again!

I've contacted Solaredge and the word is that the integrated inverter is essentially a grid-tie inverter with a built-in EVSE. So it will shut down without grid power, at least with the current release anyway later this year. It doesn't have a preference setting to use more solar power over grid. If...

Re: New Owner - Ben got an iMiEV - Again!

very nice looking installation and panels. They look like Astronergy panels I have on my roof. I am wondering if you have a plan to keep the micro-inverter on during power outage, in order to continue charging your iMiev ? eventually, you can pick up an "inexpensive" used iMiev/Leaf and ke...

Re: Best charging practices for battery longevity

thanks for all replies. I did find this yesterday "..• 75–65% SoC offers longest cycle life • EVs use 85–25% SoC to prolong battery life • 100–25% SoC gives long runtime, makes best use of battery, but reduces battery life." at this web site: http://batteryuniversity.com/learn/article/how_...

Re: Best charging practices for battery longevity

I just re-read this thread for the same reason as the title, but for a BoltEV application. Let's say if the iMiev has a 60kwh pack and your typical daily usage only needs 16kwh, about 60-miles, or about 25% of the pack capacity. What is the recommended SOC % to hover around for daily charging ? some...

Re: Solar panel charging

We have already have a 5kw grid-tie system and am just toying with the idea of adding more panels. The easier and most cost effective way would be to slap on additional panels with micro-inverter grid-tied. Since our address is already permitted for solar production, it ought to work just fine; thou...

Re: Solar panel charging

Given that PV panels and inverters prices are definitely getting better and better; I am thinking of adding some panels diy but don't want to hassle with permit and inspection etc... I recently found a local distributor so I wouldn't have to pay shipping. One option is to do an "off-grid/standa...

Re: 12 Volt battery is failing, I'm looking for replacement

my plan is to go cheap, since i don't think there is very much demand on the 12v battery. https://www.harborfreight.com/12-volt-35-amp-hour-universal-battery-68680.html $70 at HFreight (less the usual 20% coupon). I've used these on numerous Prius. Is there any reason this 35Ah 12v wouldn't work in ...
