Inspect HV insulating gloves.
참고Check gloves for damage prior to use, Refer to service document TN-15-92-003 R1, for information on inspecting HV gloves.
-
Put on HV insulating gloves and
leather over gloves.
참고Make sure to wear Electrical Protective Gloves any time Hioki tester is used.
-
Install amp clamp to RDU HV
harness.
참고Verify meter is zeroed out before performing measurement, Measure single cable. Verify ammeter is installed in correct direction. If current > 0.5A do not proceed with disconnecting HV connector. In this case, start vehicle electrical isolation again to make sure that all was properly shut down. Escalate for assistance as requiredIf current < 0.5A, Ok to disconnect and check voltage at HV plug on the battery side.
-
Release RDU HV harness from HV
battery.
참고1x connector, Release locking tab and rotate the release lever up to disengage the connector, Do not force the release lever up, Ensure the alignment tabs on the RDU header are not damaged.
-
Verify no high voltage at RDU HV
header.
참고Make sure to wear PPE (HV gloves, safety glasses) when working on high voltage component, Measure B+ to Ground, B- to Ground, B+ to B-, If voltage is greater than 10V, Pack contactors are not open or welded, Stop work and reach out to Service Engineering.
-
Lower vehicle until tires are touching
the ground.
참고Raise lift off locks, then hold lock release lever to keep locks free while vehicle is lowered.
-
Cut away insulation covering pyro
cover.
참고If insulation is present then cut away.
-
Remove pyro disconnect cover.
참고2x bolts, E10, 10 Nm.
-
Remove the pyro disconnect
insulators.
참고2x insulators, Make sure to wear proper PPE from this step onward until the ancillary bay cover has been secured.
-
Remove bolts securing pyro disconnect
to ancillary bay.
참고2x bolts, 5 Nm + 60 degrees, Discard after removal.
-
Remove pyro disconnect from
ancillary bay.
참고1x connector from the bottom, Lift pyro disconnect straight up and out of the ancillary bay.
- Install pyro disconnect dummy cover.
장착
- Record the replacement pyrotechnic battery disconnect serial number and part number for later entry into SCA.
-
Perform a zero adjust of the Hioki
resistance meter in preparation to measure resistances later in this procedure. See
저항계(영점 조정).
경고이 절차의 남은 단계를 진행하면서 HV 절연 장갑 및 가죽 장갑 보호구를 착용해야 합니다. 별도로 명시하지 않은 경우 장갑 또는 보호구를 벗지 마십시오.
- Remove pyro disconnect dummy cover.
- Use an IPA wipe to clean the HV mating surfaces of the shunt, busbar, and the pyrotechnic battery disconnect, and allow at least 1 minute to fully dry.
- Set the multimeter to the "LoZ" (low impedance) mode.
-
Measure the voltage between the busbar
(top) and shunt (bottom) for at least 10 seconds, so as to balance the voltage across
the pyrotechnic battery disconnect mount points.
참고The voltage displayed on the multimeter is not as important as balancing the mount points.
-
Position the pyrotechnic battery
disconnect into the ancillary bay, align the pins of the connector with the disconnect, and
then press the disconnect straight down onto the busbars.
참고If the pyrotechnic battery disconnect immediately triggers, perform these alternative steps, otherwise go to step 8:
-
Install bolts securing pyro disconnect to ancillary bay.
참고2x patch bolts, 13mm, 5 Nm +60 degrees, Install new fasteners.
-
Measure resistance from pyro disconnect to busbar.
참고1x HV joint, 0.060 mΩ (60 μΩ) or less, Verify Hioki tester is properly zeroed before usage, If the impedance is higher, escalate a Toolbox session, as appropriate.
-
Measure resistance from the pyro disconnect to shunt.
참고1x HV joint, 0.045 mΩ (45 μΩ) or less, Verify Hioki tester is properly zeroed before usage, If the impedance is higher, escalate a Toolbox session, as appropriate.
-
Install the pyro disconnect insulators.
참고2x insulators.
-
Install pyro disconnect cover.
참고2x bolts, E10, 10 Nm.
-
Raise vehicle fully and lower lift onto locks.
