eGPU is disconnecting from Lenovo T580 Thunderbolt3 when battery is fully charged

I'm using Lenovo ThinkPad T580 and would like to connect eGPU Sonnet eGFX Breakaway Box 550 with GTX970.

 

When I connect Thunderbolt 3 cable to upper USB-C socket I get error "Thunderbolt device functionality might be limited" I was not able to find any useful information about this issue.

 

So I connected Thunderbolt 3 cable to USB-C socket which is used by docking station.

 

It works fine I was able to install nvidia drivers, but it works perfectly only during the time when battery is charging. When battery is fully charged egpu starts to disconnect/connect all the time. The screenshot shows last moments before it goes through endless disconnect/connect cycles.

 

This eGPU works absolutely fine with my other laptop Dell XPS13 (whether it's fully charged or not)

 

I updated BIOS and already tried different Thunderbolt 3 settings in BIOS.

 

Is there a way to fix this issue?
