High-voltage battery

 Danger

Risk of fire/risk of explosion due to short circuit and escaping oxyhydrogen gas. Risk of (burn) injury caused by caustic burns to eyes, skin and mucous membranes from battery electrolyte/mist, short circuit and arcing. Risk of poisoning caused by swallowing battery electrolyte or absorption of lead through the skin or body orifices. Risk of death due to voltage U >= 30 V AC and U >= 60 V DC.

No fires, sparks, open flames, or smoking. Wear acid-resistant gloves, clothing, and glasses. Pour battery acid only into suitable and appropriately marked containers.

AS54.10-Z-0001-01A

 Danger

Risk of death when working on component parts and systems with U >= 30 V alternating voltage (AC) or U >= 60 V direct voltage (DC)

Do not touch damaged or defective live component parts and lines or non-insulated electrical connections and lines.

Check

1

Check whether you have the required qualification for assessing the safety of high-voltage on-board electrical systems.



Service Information: Qualification measures for working on high-voltage on-board electrical systems, lithium-ion batteries and gaseous fuel drive systems

SI00.00-P-0156A

Checks before entry into the workshop for a vehicle with faults in the high-voltage battery module (A100) or accident damage

2

Before entry into the workshop, check the high-voltage battery module (A100) and detachable parts in the area of the high-voltage battery module (A100) by means of a visual check for fire, smoke development, consequences of a fire, or internal heat development.

AR47.70-P-0017-01A

 Protocol points in the event of an acute hazard:
A1 Smoke
A2 Fire
A3 Heat development

 Smoke is often an early indication of fire.

If smoke development, tarnishing, or charred detachable parts are determined,



Immediately make an emergency call under the respective location-specific and country-specific emergency call number and do not touch the high-voltage battery module (A100); vacate the danger zone.

3

Before entry into the workshop, check whether accident damage to the underbody or in the area of the high voltage components is present.



Service Information: Handling high-voltage batteries after an accident with airbag and/or pyrofuse triggering

SI54.10-P-0035A

4

Before entry into the workshop, check whether you perceive a pungent odor in the area of the high-voltage battery module (A100).

AR47.70-P-0017-01A

 Protocol point in the event of an acute hazard: A4 electrolyte leakage (visible/smellable).
The opening for pressure relief is located on the top of the high-voltage battery module (A100) and is not accessible. Electrolyte is volatile and has a pungent odor.

Additional checks in the workshop for a vehicle with faults in the high-voltage battery module (A100) or accident damage

5

If no problems are found during operation steps 2 to 4, take the vehicle to the workshop.

6

Connect vehicle diagnosis system and run quick test.



AD00.00-P-2000-06FR

If a fault message is present in high voltage components or an isolation fault is present,



rectify these problems as part of the maintenance work in accordance with the repair documentation.

7

Lift vehicle with lifting platform.

AR00.60-P-1006A

8

Check the housing, incl. threaded connections of the high-voltage battery module (A100), for mechanical deformation, cracks, and openings.

AR47.70-P-0017-02A

 Protocol point: B1 to B5
Mechanical protective cover/housing damaged.

9

Remove high-voltage battery module (A100).

If, as a result of previous tests, the high-voltage battery module (A100) needs to be replaced or of the high-voltage battery module (A100) needs to be removed for further tests.
