Discharge
WARNING:
To conform with local laws, High Voltage Lithium Batteries must
be discharged before packing for shipment. Additionally, HV
batteries must be discharged before being put into storage. HV
batteries to be shipped must have a State of Charge (SoC) of
less than 30% or 50%, depending on the region. If the method of
shipment is unknown or uncertain, or the battery is to be
stored, it is recommended to discharge the HV battery to less
than 30%.
WARNING: Do not ship or store an HV battery that has a loss of high voltage isolation. Verify HV battery isolation before packing for shipment or storage. Use the HV Battery Communication Tool, described in Toolbox article #41977 or Customer Document CD-21-16-003, to determine if the HV battery parameters are within safe limits for shipment or storage. |

At the ancillary bay, use the Hioki resistance meter to measure the resistance between the charge port busbar lead and the ancillary bay HV header bolt head. Also perform this test on the other lead and bolt head.
NoteThe acceptable resistance is between 0.050 mΩ (50 μΩ) and 0.195 mΩ (195 μΩ). If the measured resistance is above 0.195 mΩ (195 μΩ), there is too much resistance in the High Voltage joint. Remove the fastener, clean areas with isopropyl alcohol, install fastener back and test again, as appropriate.NoteIf the resistance is lower than 0.050 mΩ (50 μΩ), reposition the probes and measure again. If after 4 attempts the resistance is consistently lower than 0.050 mΩ (50 μΩ), the test has passed; continue to the next step.
