My current project is a 2015 leaf with 24kWh battery @ 58% SoH
I have added an extender battery into the boot, from a 2015 30kWh leaf @ 62% SoH. This is wired directly into the PDM, using the same bolts that connect busbars inside the PDM. This avoids possible water ingress into spliced HV wiring. Balancing is done weekly with a separate LBC. It all works well. No fault codes. Range is extended but I haven't run it below 30% SoC yet
Combined battery capacity should be around 32kWh
I can fast charge it to 100% SoC
But it doesn't slow charge (L2) beyond about 75% SoC
Any ideas what is causing this behaviour and what needs to be done to fix it?
TIA
