Re: for sale 2012 Miev Chicago area

i would bet that your problems will go away when you replace the OEM aux battery. Put the money for the obdii tool toward a new battery. i hardly ever use my scantool, but i use that battery every day...

Re: Turtle at Half Charge Under Load?!?!?!

What is the age and condition of the 12V aux battery--is it the original OEM or has it been changed, etc.? We have a separate thread devoted to troubleshooting the OBC/DCDC Converter with lots of detailed information in post #2 about testing the 12V aux battery. i would have expected to hear that th...

Re: Turtle at Half Charge?!?!?!

Please add "under load" to your subject line. Usually if turtle mode is triggered, it doesn't turn off until the pack is re-chargged. But in your case the light comes on under high load with a full throttle and with the Heater ON, then turns off when you release the throttle. Try again wit...

Re: Battery Degradation

But the fact that the cells do not fall to the required level of 2.8 V is also caused by a bad cell ?? and what can be done now? It is believed that if you replace one new element, the device will stop charging, is it true? The car will shut down when only 1 cell reaches the low voltage limit, and ...

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

That session was just short of 4 hours, and the current ramp-down started after a little less than 2 hours. It says you added 6.64 kwh, and you said that it was 3 bars short of full. So when you started the session you were at about 7 bars. 4 hours at a true level 2 will usually add about 12 bars, s...

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

From an engineering standpoint, there are numerous relays and contactors throughout the vehicle that are critical for safe vehicle operation and for chargging, and some must never be switched under load due to arc-flash damage to the contacts. The 12V aux battery is the power source for the energizi...

Re: Battery Degradation

They appear to be the same sized cell, but it's not clear if these are new or used. Also based upon the limited description information (for example: "Brand: AAA") it's not clear that these are actual G.S. Yuasa LEV50 (50 A-Hr) cells, or some copy, but they do look like real Yuasa LEV50 ce...

Re: Battery Degradation

Howdy Aleks, Welcome to the forum. It appears that cell #43 is weak and probably worn out. Due to the operating system, the capacity and range of the battery pack is limited by the weakest cell. We have seen a member (Martin) replace just the one weak cell and restore his pack, see a video in this t...

EVSE relay and Main Contactor sequence observation

Recently i made an effort to notice the J 1772 push-button sequence on my Bllink Level 2 (240 vac) EV SE. It occurs almost instantly, but after a very brief delay the EV SE relay opens first, then about 1 second or less later, the contactors in the car can be heard to open. [edit] i repeated the obs...
