Re: Mitsu Tech said I set car to not charge on Mondays

logicalmethods, glad to hear the 12v battery replacement solved your car's erratic charging behavior. 1) The 12v battery is the source of most of the problems experienced by the i-MiEV, although it is normally not an issue while the car is charging (because the dc-dc is keeping the 12v at the proper...

Re: Care and Feeding of the OBC/dc-dc

Depressing the button on the J1772 connector while its plugged into the car results in a seemingly-instantaneous relay click in the EVSE. The resolution of my power monitor isn't good enough - need a scope. Edit: Update. This morning I paid attention and I could swear that the sequence was (the car ...

Re: Got Solar!

ed5000, does your water heater have a heat pump? I have a GE GeoSpring, but it had issues and I've modified it for TOU.

Re: Care and Feeding of the OBC/dc-dc

Coulomb, thank you very much for your detailed explanation with the schematic - I should have reviewed the J1772 interface myself before posting. The concept of the J1772 switch triggering the vehicle controller to first ramp down the charging power had escaped me. Presumably, using the Remote does ...

Re: Care and Feeding of the OBC/dc-dc

This post is about turning OFF power to the car when charging. There are four ways that the car turns off charging - 1. When it is fully charged, the OBC sends a shutoff signal to the EVSE which stops the power flow 2. When timed using the Remote, presumably the Remote receiver sends a signal to th...

Re: Euro spec i-MiEV, 2013 mod, LED headlights

Too bad I can't see the pics. The photos show up fine on both my iPad and MacBook. You might try using a different browser. Edit: Just tried it with a very old Mac Mini and obsolete OSX using ancient Safari, Google Chrome, and Firefox browsers, and all the photos showed up on each of the browsers. ...

Re: Charging from a variable amperage 240V supply (PV Solar)

TrojanHussar, when you export electricity to the grid, does the power company use that to reduce your bill or do they pay you for it? I like to think of the grid as a huge battery that temporarily stores the energy I've given it; in my case, the power company uses what I export to it simply to reduc...

Re: Care and Feeding of the OBC/dc-dc

PV1, thanks for that and for bringing attention to yet another i-MiEV quirk. Never would have suspected that not starting the car after opening the door would leave a higher quiescent drain on the 12v battery. Continuing with 12v, I'm now seriously toying with installing a "12v" Headway Li...

Care and Feeding of the OBC/dc-dc

Our OBC/dc-dc is proving to be the i-MiEV's Achilles heel. Not wishing to contaminate kiev's excellent thread detailing the troubleshooting and repair of the On Board Charger (OBC) which also contains the pack-to-12v dc-dc converter, I thought I would start this thread specifically to pursue the min...
