Re: Supplemental cooling for the charger.

Finally get a chance to poke around the on board charger/DCDC. Boy that thing can really get warm. It seems that one of the problem is that there is no way for the hot air to circulate, it gets all pooled into that canopy. Aerowhatt's fan is great but I would add a hose to duct cooler air lower down...

Re: [POLL] On-Board Charger and DC/DC Converter

1. Year and mileage on your iMiev: 2014, ~20kmiles 2. OBC failure experience: none, but now always lift up rear hatch when charging L2 since learned of the problem on this forum. Thank you all so much !! 3. 12V Battery Condition, Age: original 4. 12V Battery Maintenance Frequency and Procedures: the...

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...
