There is current measurement after the fets, see the curled up busbar.
Wait a minute, why would the fets control the HV to the 'grey' HV connector and measure current?
So would this mean that the PTC heater (water???) be a dumb module? Ah 2013 module looking at some info the battery heater just needs a pwm into the junction box.
Plus nice isolation devices (Big SMD packages) just like on the bms slaves.
