Overview
The Tesla Model S GEN1 Rear HVJB was a High Voltage Junction Box found in the all 2012 through late 2013 Model S. It is centrally located under the rear seat frame, and the Single or Dual GEN1 On-board Charger(s) are located to the right and left of it. It was replaced via gradual phase-in by the GEN2 Rear HVJB starting around Oct2013, when the GEN2 On-board Chargers were introduced; the GEN1 & GEN2 Rear HVJBs are not interchangeable, physically nor electrically.
It functions as a junction for connections to these subsystems:
- Traction Battery Pack (HV DC)
- Drive Unit ("Inverter") (rear only, as the Dual Motor option wasn't offered during the GEN1's life)
- Charge Port (AC and DC input)
- DC-DC Converter (GEN1, which also functioned as the Front HVJB)
- On-Board Charger(s) (GEN1 Chargers only)
Connections
HV
LV
The LV connector on the bottom left side is a 12-pin Molex MX150 series (Molex p/n: 33472-1201). Only 6 of the 12 pins are populated, as follows:
| pin | function |
|---|---|
| 4 | 12V |
| 5 | PWM in |
| 6 | STATUS out |
| 10 | GND |
| 11 | HVIL in (not needed) |
| 12 | HVIL out (not needed) |
