Re: Need a longer range ev

I would try to find out if there is any near future plan for DCFC installation along your route, as well as to consider your time frame. I don't know how near retirement you are, but your driving need would change. We have an 2014 iMiev, '16 Volt, and a '17 Bolt; totally now over 100K electric miles...

Re: Troubleshooting and repair for On-board Charger (OBC), DC-DC Converter

hi y'all - I am still struggling to convince myself that it's best to stop charge with the trigger. Most relay contact needs some sort of protection upon a disconnect, due to the inductance back discharge. Recall the old days with ignition points & condensers. Sure, you would think that Mitsu de...

Re: Troubleshooting and repair for On-board Charger (OBC), DC-DC Converter

hello - am I understanding this correctly that these cap and resistor are there to protect the relay contact, mainly upon disconnect ? if so, would it more prudent to turn off charging externally by turning off the EVSE AC power rather relying on the relay contact ? am just looking for some preempti...

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_...
