I have several samples of 'good' 48 amp multi-hour charge sessions on different HPWC's. The 'normal' temperature of my samples is suggesting a plateau of maybe ~145F with good relays and the HPWC in a shaded garage at ~70F. I don't recall the handle temps, but 110F seems reasonable. I don't know where the HPWC will start throttling, but it looks like you've found that to be perhaps 200F. For reference, 75C is 167F, while 90C is 194F.Ok. The engineer in me is gonna drive me nuts if I keep staring at this. What do we believe to be the normal operating temperature of the gen 3 when charging at 48A. I have the wall monitor app measuring the PCB, Handle, etc. As well as a temperature gun.
I have read the trip temperature (three red lights) to be ~200F on the PCB and 110F on the handle. Agree?
Regardless of that, what do we see as nominal during 48A charging for multiple hours (evened out steady state)?
The relays on Gen3 HPWCs models ending in -F and before are known to be dubious. Each of the two relays has two contactors in it, and if one is notably better than the other, the relay will overheat and may eventually completely fail.
