System voltage high P0563 Error Code

[Cradle]

I have a Fieldmaster with Ctek 120s and D240se with a lithium Lifepo4 battery 300A as second battery. The duel battery system was set up at factory and I only replaced the original FEB battery with the lithium. This year I travelled through Simpson Desert and Around Alice Springs. The second battery was charged so well and there was no shortage of power for my rice cooker, induction cooker and water kettle. I did not see this error code when travelling. However, I have not driven the vehicle lately and the second battery got drained almost to 15%, which is the protection level. Main battery was almost normal at 75%. This error came out twice. My AI research came with this advice;

• Lithium low → aggressive bulk charge
• Smartpass opens
• D250SE demands current
• Trickle path allows reverse influence
• Voltage excursion occurs
• P0563
  

Has anyone experienced yellow Engine warning light on the dash connected to System High Voltage? Now, I am thinking of solutions on this issue.

A 300A Lithium battery is a really big battery and it can take a large bulk charge. The CTEK 250SE can only charge the Lithium battery at 20 amps.* I wonder whether there is a mismatch when the Lithium battery is drained like you say.

What is the charging voltage showing on the Electrical screen when the error occurs?

Do you have a battery monitor fitted to both batteries? If yes, what are the graphs showing?

What brand is the 300A Lithium battery? The CTEK system, in the IG, is not designed to charge such a big battery. When driving many kilometers a day that might not matter, but parked up that is a different scenario.

* I have assumed the 250SE is set to a Lithium charging profile for the second battery.

I’m no expert, but I’d start by isolating the batteries and charging them separately with a smart charger.

From my reading of the Ctek manual if you only have a D250se then the charge limitation is 20 amps but paired with a Smartpass 120S its considerably higher at 120amps.

X2 checking that the lithium profile for the service battery is enabled in the D250SE. I also agree with @Logsplitter it would be worth charging the batteries separately and seeing how they hold charge.

Also remember that Li batteries are generally not designed for starting applications and there may be issues if the starter battery can't start the car and the Smartpass connects the 2 together. In this case the amp draw may exceed the limit of the Li battery which may cause damage to the Li battery. The Smartpass trickle charging function shouldn't flatten the auxiliary battery unless the vehicle is parked up for a very long period.

The lithium battery is from Ecowatt and it gets charged really fast. Ctek can charge maximum of 300amp batteries according to their manual. From 70% to 100%, it only need just one hour drive. Yesterday I drove 45 minutes twice, thus all up 90 minutes. The lithium battery was flat at 15% but when I finished driving it was at 79%. It's a smart battery which i see all data on my phone app. My phone connects to the battery direct via Bluetooth. It also shut off if excess amp is taken out. Once I was cooking with an induction cooktop and I mistakenly turned on a water kettle. The battery shut itself off. With the app, you can reopen the power again. I removed the error code halfway yesterday, and drove the other half but no warning light came out. I will observe more from now on.

If the 120S and 250SE can give a combined 140 amps to the Ecowatt Lithium battery, the battery take a charge up to 300 amps (recommended charging rate is 150amps - which is a big number). That could also explain the error message, because that would be a big power drain on the car electrics, even for the IG. What is the IG console showing as the amps being drawn during driving?

I am not sure you can combine the charges when there are two different battery chemistries involved. We should send a message to CTEK and find out. Maybe it can, with the alternator charging the main battery and the 120S and 250SE charging the aux battery.

Charger makers love to quote figures in manuals, but as a board rule of thumb I have heard sparkies say a system should not be run continuously above 80% of the system’s capacity. My 50 amp Anderson circuits are fused at 40 amps, not 50 amps.

Does your phone app tell you the battery temp of the Lithium battery? Because if it is charging as quick as you say - I suspect there is a lot of heat being generated and the CTEKs maybe really hot. For example, on my Invicta lithium battery box (BB), the 25 amp charger gets extremely hot, after about 30 minutes. I am talking burns your hands hot. I plug a USB fan into the BB and point it at the charger to control heat. I think this happens because the Invicta Lithium battery can keep drawing a charge at 25 amps and the little charger is therefore working its rear end off 100% of the time - without active cooling.

The CTEKs do not have active cooling either. If they are working at 140 amps, I suspect they need it.

Grenadier's battery charging status panel looks always normal to me.

The Ecowatt battery company once checked my history online and advised me to lower the voltage from Ctek. I will talk to Ctek to find out more, and Ecowatt as well to analyse the battery data.
