Add my 2017 to the list. First indication was a check engine light. Then went away. Then came back. Then charge interruptions. Then no battery information. Then shift to park. I managed to use a jump battery box to start it and it found the HV batt again. Drove straight to the dealer where its been for 4 days. TBD how it goes.
The following message: Attention: 12V battery low. Please start the engine or switch off the infotainment system. There was also a yellow "12V battery low" warning on the cluster, but forgot to snap a pic of that one. The car was NEVER slow to turn over, or gave me any problems whatsoever starting. The car would charge at 13.3 to 14.6v.
4. Battery Control Module (BCM) and 12V Battery Problems. The Battery Control Module (BCM) is a critical component in electric vehicles like the Jaguar I-Pace. It plays a key role in managing and monitoring the high-voltage battery pack. However, BCM-related issues can occasionally lead to charging problems.
The solar panels charge the lithium battery through the TP4056 battery charger module. This module is responsible for charging the battery and prevent overcharging. The lithium battery outputs 4.2V when fully charged. You need to use a low dropout voltage regulator circuit (MCP1700-3302E) to get 3.3V from the battery output.
When the laptop is turned off, charge the battery for some time. Or, restart the laptop and tap the F2 key to enter the BIOS or System Setup. Allow the battery to charge. Verify if the battery charge percentage has increased. Restart the computer, and go to the next step.
