Traction battery
Removal
From the hatch opening:
- Remove the carpet in the hatch compartment floor, to reveal the battery
- Turn the orange safety plug from LOCK to UNLOCK and pull it out
- Remove the black plastic air coupling on the rear-left
- Remove the bolts on either side of the battery (3 bolts on each side)
- Disconnect the battery:
- Orange HV connector on the right (flip the lever)
- Big black signal connector on the left (unscrews)
- Small connector next to the signal connector (snaps)
- Hook an engine hoist to the two round holes in the black metal on either side of the battery
- Hoist the battery out of the car
To open the battery:
- You need a #35 security Torx driver, and a #35 Torx driver
- Remove all the screws in the 2 top covers
- Cover over the fans
- Cover over the batteries and electronics
General description
Component locations
The battery includes (as seen when in the vehicle):
- Air blowers in the rear compartment
- NiMH cells in the center
- 2 layers of cells
- each layer in a left and right group
- each group has 13 columns of 5 cells in series
- total: 2 * 2 * 13 * 5 = 260 cells
- pack voltage: 1.3 V * 260 = 338 V
- controller on the right side
- contactors and HV connector on the right-front corner
- safety plug on the left-right corner
- a converter of some sort on the left side
Connectors
The battery has 3 connectors, with a total of 34 wires:
- C4227A - 28 wires - control
- C4227B - 2 wires - low power HV to the AC/DC converter
- C4227C - 4 wires - traction HV, interlock signals
