I'm using Lithium battery (including self make battery pack), with charging / discharging in RC Model Airplanes since 2001 I also experience in the hard way what is the result to store for 5/6 years battery left in fully charged status .. battery capable to deliver over 10A current, now capable...

I think this point has been discussed in 2 or 3 or even more posts in this thread ... check page 2 and 3 About the real SOH .. this is an interesting topic I believe .. the only way to test real SOH is: Fully charge the PHEV Wait 2h for battery to rest and avoid any BMU madness with SOC above...

Question I normally have the switch for internal light set to have cabin light when door are open. When I do this procedure I need to keep the trunk open .. so by default the light would be on. When I did the long procedure, it was in the night, and I did switch off the internal light, else...

About the fuel pump fuse I did try it, and somehow it works .. but only somehow It works fine on the first usage .. the car try only once to start the engine .. it fail .. it show an error on console and does not try anymore But .. on next day or next restart .. it does try multiple time to...

Super job michalsarna We have both your video and the picture of audio file .. it is looking the connection/disconnet process is around 3.2 seconds I will try to replicate this on my car in the weekend

No While charging there is always the DC/DC that provide 12v (normally for charge the 12v battery) from the main battery to the car 12v system line .. so no issue on this Anyhow ... I don't get the issue on slow charge

No it is cycled. It get charged up to 33/35% SOC and discharged down to 30% At high speed the ICE will never stop, but still it charge and discharge the battery around the 30% SOC Even at high speed, still it is needed the main battery for power the eMotor for reduce the drag, plus there is...

Did you record the successful procedure ? In case it will be super if you post it on youTube :ugeek:

Maybe you can try to record your 1-2-3 ... and extract from it how many seconds it did take (any decent wave editor should be able to show the length of a audio segment) ... and add to this if there was any delay between connecting and disconnecting from the wording ... So .. maybe we can have...

:ugeek: :geek: :ugeek: What about get a relation with the sounds. My car once I reconnect the 12v does a sequence of 3 or 4 click .. from the car. Then after this there is a click from the charging box If I stop before the charging box make a click, the charging process will not start, so...

Yes, you are right, you did not mention anything above 4.1v About 10% ... I'm not sure ... I was reading that ideal storage SOC for Lithium battery is between 30% and 50% Yes, some chinese company ship Lithium battery with 10% SOC, or even less, but I believe this is because of airlines...

I'm also failing so far ... I also tried: Simple BMU Reset (Lindqvist method without all the unnecessary parts) 1. Drain Phev battery at least a bit and disconnect 12V battery (-). 2. Connect Phev charger. 3. Connect 12V (-) battery for 3 seconds to start charger. 4. Monitor battery capacity...

I don't think you can even be accurate in this way When voltage get depressed, due to high load and eventually low temperature, it can take hours before the voltage bounce back to the proper unload value .. this is why the BMU take care of the 2h rest before update the SOC after usage. If you...

Discharge curve is very specific to: - Temperature - Load In winter on a highway you might expect to see even 3.3v at 50% SOC In summer on moderate usage, and after some regen .. 4.0v can be seen at same SOC I don't see how you can use this information Only valid information is Voltage per...

Charging is never above 4.1v .. and has nothing to do with SOH About hybrid mode ... if you start a long trip, the hybrid mode will kick in at around 30% SOC, now if SOH was wrong and trip start with SOC around 100% ... Then in automatic mode the car will run in EV mode until 30% SOC, which...

It never happen to me .. also because my old PHEV does not have the Ev button. Possibly the best solution would be to stop the car and restart ... but it might not be an option on highway I think that once the ICE kick in, it does want to run a bit for avoid to stop its operation while it is...

This does not sound good. Yes if the SOH is artificial set to 38Ah while the real battery SOH is only 30Ah or less ... yes it is possible to "over discharge" the battery .. like the guy sportster999 is reporting I think bring regularly down to 3.6v is not good. Even worst is to make a long...

I did try on my 2013 PHEV but it did not work for me I did read from success "stories" that 12V 3 to 5 seconds reconnect for start the charging process .. in theory it should reconnect only until hearing the first click (in my case I let 3 clicks before disconnect the 12v) I will try again ...

The DBCAM is possibly a proper procedure for "re-calibrate" the BMU But the improvement seen by people have nothing to do with balancing, as said this happen all the time the car is charged. The DBCAM make a more deep discharge and then based on the following amount of charge does set a new SOH...

If I would know nothing about Lithium battery, I would believe fully on what state above. But ... there are few things that I know very well, and I don't like to mix good things with wrong legends .. as happen above The battery smoothing/balancing is a legend The battery is kept balanced...
