Tesla Model S

 

Love my Tesla S -

The car has an On-Board Charger Module with feeds the Rapid Splitter (Front Junction Box), the Rear motor inverter and High Power Distribution Module (HPDM) (Front junction block) to battery coolant heater control circuit, high voltage connections from the Rapid Splitter to the HPDM The front motor inverter, the electric air-conditioning compressor, the 2500 Watt DC to DC converter, a High voltage battery coolant heater controller and Positive Temperature Coefficient (PTC) Cabin Air Heater.

Model S SEE Orange cable core and shielding cables  74 feet of high voltage cable through 10 different power electronics components of a 2015 and later Tesla Model S AWD.
