Voltage Check

• Be sure to read and follow the "General Safety Information and Caution" before doing any work related with the high voltage system.
Failure to follow the safety instructions may result in serious electrical injuries.
1. Measure the voltage between the service disconnect plug upper (+) terminal and [High voltage battery –PRA] connecting cable (-) terminal.
→ Specification: About 150 V
2. Measure the voltage between the service disconnect plug lower (-) terminal and [High voltage battery –PRA] connecting cable (+) terminal.
→ Specification: About 120 V
If the temperature continues to rise when measuring it at 30 minute intervals, submerse the
battery in salt water immediately.
3. Isolation resistance check(using a MΩ tester)
(1) Measure the isolation resistance between the power relay terminal (+) and the battery pack
cover.
(2) Measure the isolation resistance between the power relay terminal (-) and the battery pack
cover.
▶ Criteria: 5MΩ or less (at 500V)
▶ Measures: Insulate the battery using insulating materials.
(Refer to "Take insulation actions for parts that may short circuit.)
4. Take insulation actions for parts that may short circuit(Visual inspection)
(1) High voltage battery – PRA cable terminal
(2) BMS voltage sensing connector
▶ Insulation actions
– Use the insulation tape or rubber cap to prevent short circuit to the battery pack, cells, modules.
– Fix the connector terminal to prevent wiring from moving.
5. Electrolyte leakage check
– Check for odors within 30cm of the battery pack (electrolyte odors like chemicals or acryl).
▶ Measures: Submerse the battery in salt water immediately if a smell is detected.
Remove the service disconnect plug and store the battery under the same conditions as a new
Storage
battery.
Transport Minimize impacts and ensure the battery does not come in contact with other parts.
Transport the battery to the designated disposer; discharge it by submersing it completely in salt water
Disposal
and carry out the disposal procedure.
Remove the service disconnect plug; insulate all exposed terminals; place the battery in a cool, dry
place away from volatile or combustible substances; use insulating materials (insulation tape, rubber
caps, etc.) or vinyl to wrap the battery; use anti-shock materials inside the box.
Storage
▶ Insulation action: Refer to "Take insulation actions for parts that may short circuit.
▶ Packing: Abnormal battery must be packed as same as a new battery.
Transport Minimize impacts and ensure the battery does not come in contact with other parts.
Transport the battery to the designated disposer; discharge it by submersing it completely in salt water
Disposal
and carry out the disposal procedure.
