Re: i-MiEV Cuts Out After Hitting Bump

A while ago, my motorcycle died right after hitting a pothole. Apparently the shock loosen something in the 12v battery and sorted it out thus overloaded the generator/alternator. I would also check the 12v health.

Re: i-Miev Battery Cell Testing

I think you are referring to charge shuffling. I am not sure if it's possible for deeply out of balanced cell, and if it does, it may take a really long time. Imagine a worse case scenario where all cells are around 80% SOC, and the one newly swapped cell is at 10%. The available range would also si...

Re: i-Miev Battery Cell Testing

The challenge is how to balance the cells with respect to each other, since they are all in series ? When I rebuilt the Prius' pack, I had to connect all the modules in parallel for a couple of days while exercising slow up/down charging. At least with the Prius pack being NiMh, one can top balance ...

Re: Annual inspection and "required" maintainence?

hello everyone, I finally get around to bring my 2014 with 21Kmiles in for the airbag recall. The dealer insisted that I need to do the Maintenance (~$4xx) in order to keep the warranty. I thought that's a bit steep; and the main items listed in the Maintenance schedule are high voltage cabling insp...

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...
