I've not paid much attention to this thread lately so sorry if this is repetition.
The current issue of Racecar Engineering has a write up on the TS050 which includes an insight into the cooling testing Toyota were doing outside of EoT parameters at the Prologue.
The battery pack used to be air conditioned and the compressor was driven by the front electric motor. That's why it took so much longer to change the front hybrid system at LM last year compared to Porsche, who had a similar failure. The gas in the air con had to be evacuated and then recharged, adding half an hour to the process.
This year they have ditched the air con in favour of conventional radiators, hence the extra stress testing.
It seems the new system is lighter too. Although the rads are bigger, no air con means no compressor or condensor.
There is no cabin air con either, just vents and fans.
